nagios plugin support (#21294)
* nagios module * zabbix module * fixed CI failures * Tidy up package description to better align with our other descriptions. Also use the correct minimum version for the conflicts line. * Fix up permissions handling in DEB postinst script. * Actually enable plugin for DEB package builds. * Add plugin to RPM packages. * go mod tidy * go mod tidy * move zabbixprecproc pkg * cleanup * fix: remove duplicate Job.Module() method introduced by merge * refactor: use label prefix convention for vnodes, add metadata, fix race - Replace Address/Alias/Custom fields on VirtualNode with label prefix convention: _address, _alias for reserved macros, _VAR for custom host variables, unprefixed for regular labels - Remove duplicate Job.Module() (master already has it from #21595) - Add metadata.yaml for nagios, zabbix, and scheduler modules - Update config_schema.json to document label conventions - Fix data race in Scheduler.armTimer() by capturing ctx locally before passing to timer goroutine closure * fix: scheduler restart safety and metadata accuracy - Nil timers in Stop() so restart recreates closures with fresh ctx - Fix zabbix metadata: state dimensions match actual emitter code (collect_failure/lld_failure/extraction_failure/dimension_failure/ok) - Fix nagios metadata: vnode path is /etc/netdata/vnodes/ not vnodes.d/ - Fix scheduler metadata: "per-job timers" not "timer heap" * refactor: remove TypeOverride from go.d Chart struct Dashboard groups charts by context, not chart type ID, so TypeOverride provides no user-visible benefit while adding complexity to the core framework. Charts now use the default job.FullName() as their type ID. * fix: collapse multi-line alert expressions to single lines Netdata health alert parser does not support multi-line warn/crit expressions. Also replaced multiple lookup lines in nagios_state with calc referencing dimensions directly. * style: go fmt alignment fixes after TypeOverride removal * fix: use static chart titles and remove dev stock configs - Replace dynamic per-job chart titles with static titles - Remove nagios.conf and samples.conf stock configs (dev paths) * chore: remove TODO files from PR --------- Co-authored-by: Austin S. Hemmelgarn <austin@netdata.cloud> Co-authored-by: ilyam8 <ilya@netdata.cloud>

+# scripts.d.plugin (preview)
2
+
3
+`scripts.d.plugin` runs stock Nagios checks inside Netdata without modifying the
4
+original plugins. Jobs are executed through a dedicated scheduler/executor,
5
+perfdata metrics become native Netdata charts, and every run emits structured
6
+logs (stdout/stderr/state transitions) over OTLP.
7
+
8
+> **Status:** preview. The core execution pipeline, charts, and logging are in
9
+> place, but configuration options and documentation may still change before GA.
10
+
11
+## Configuration overview
12
+
13
+Each YAML file under `/etc/netdata/scripts.d/*.conf` (or the stock directory
14
+shipped in `usr/lib/netdata/conf.d/scripts.d/`) follows the standard go.d layout:
15
+one top-level `jobs:` array, where each entry is a complete Nagios job
16
+definition (plugin path, arguments, scheduler name, vnode, retries, etc.). This
17
+matches what dyncfg exposes—when you edit a job in the UI you are editing the
18
+same YAML object you would put on disk.
19
+
20
+Example:
21
+
22
+```yaml
23
+jobs:
24
+ - name: ping_localhost
25
+ scheduler: default
26
+ plugin: "/usr/lib/nagios/plugins/check_ping"
27
+ args: ["-H", "127.0.0.1", "-w", "100.0,20%", "-c", "200.0,40%"]
28
+ timeout: 60s
29
+ retry_interval: 1m
30
+ max_check_attempts: 3
31
+```
32
+
33
+There is no nested structure anymore—module files only list explicit
34
+jobs, and every job is autonomous. Plugin-level toggles (for example enabling or
35
+disabling modules) live in `/etc/netdata/scripts.d.conf`, but all scheduling,
36
+macros, and chart definitions stay inside the module job files just like go.d.
37
+
38
+### Argument macros
39
+
40
+Jobs can bind up to 32 `$ARGn$` macros via the optional `arg_values` array.
41
+Entries in `args` that reference `$ARG1$` … `$ARG32$` are replaced with the
42
+corresponding values before execution, and the same values are exposed through
43
+`NAGIOS_ARGn` environment variables for the plugin to consume.
44
+
45
+### Time periods
46
+
47
+`check_period` controls when a job is allowed to run. Define time periods inside
48
+the module configuration (for example `/etc/netdata/scripts.d/nagios.conf`) and
49
+reference them from individual jobs:
50
+
51
+```yaml
52
+# /etc/netdata/scripts.d/nagios.conf
53
+time_periods:
54
+ - name: 24x7
55
+ alias: Always on
56
+ rules:
57
+ - type: weekly
58
+ days: [sunday, monday, tuesday, wednesday, thursday, friday, saturday]
59
+ ranges: ["00:00-24:00"]
60
+
61
+jobs:
62
+ - name: local_plugins
63
+ check_period: 24x7
64
+ logging:
65
+ enabled: true
66
+ otlp:
67
+ endpoint: 127.0.0.1:4317
68
+ tls: false
69
+ timeout: 5s
70
+```
71
+
72
+The `logging` block enables OTLP log forwarding to Netdata's `otel.plugin`
73
+instance. The sample config keeps `tls: false` so local collectors can start
74
+without certificates; set `tls: true` (and optionally `tls_ca` / `tls_cert` /
75
+`tls_key`) to enforce encryption, even when emitting to `127.0.0.1:4317`.
76
+Adjust the endpoint, timeout, or headers if your OTLP
77
+pipeline lives elsewhere or requires authentication.
78
+
79
+### Scheduling semantics & skip behavior
80
+
81
+Every job owns a dedicated timer. When the timer fires the scheduler enqueues
82
+the job unless it is already queued or executing—matching Nagios Core's
83
+"single-flight" behavior. If a run is skipped this way, the skip counter for
84
+that job increases and the next run occurs at the normal cadence (there is no
85
+catch-up burst). Use the `nagios.runtime` chart's `skipped` dimension or the
86
+stock `health.d/nagios_skipped.conf` rule to monitor how frequently this happens
87
+and to page when a job repeatedly overlaps.
88
+
89
+### Scheduler telemetry
90
+
91
+The `scheduler` module publishes native charts so you can monitor queue depth,
92
+job throughput, and the “time until next execution” for each worker pool. Look
93
+for contexts such as `nagios.scheduler.jobs`, `nagios.scheduler.rate`, and
94
+`nagios.scheduler.next` to confirm schedulers are keeping up with load. Changes
95
+to scheduler definitions (worker counts or queue sizes) are applied live—when
96
+you edit the scheduler job, the underlying runtime is recreated and existing
97
+jobs are reattached automatically.
98
+
99
+### Charts, labels, and units
100
+
101
+Each job now derives a deterministic chart identity from its scheduler name and
102
+the fully expanded plugin command line. That signature feeds every chart ID and
103
+context, so different executions of the same script (for different URLs, hosts,
104
+etc.) keep separate time-series across restarts.
105
+
106
+- **Contexts & families** – job charts live under `nagios.<script>.<measurement>`
107
+ (for example `nagios.http_check.latency`). This keeps “apples with apples” in
108
+ the Netdata menu even when multiple jobs share a script.
109
+- **Labels** – all charts share the same label set: `nagios_job`,
110
+ `nagios_scheduler`, and `nagios_cmdline` (the fully expanded plugin
111
+ invocation). Perfdata charts add `perf_label`. The uniform labels make filtering
112
+ dashboards and health alerts straightforward.
113
+- **Titles** – chart titles describe the script + measurement (e.g. “Nagios
114
+ http_check response time”) rather than the monitored endpoint, so all charts
115
+ with a shared context render cleanly in the UI.
116
+
117
+#### Unit normalization & scaling
118
+
119
+Netdata stores integers, so scripts.d.plugin normalizes perfdata to base units
120
+before emitting metrics:
121
+
122
+| Input unit | Canonical unit | Scaling behaviour |
123
+|------------------------------|----------------|---------------------------------------------------|
124
+| Bytes, KB, MB, GB, TB | bytes | Converted to raw bytes, divider = 1 |
125
+| Bytes per second (KB/s …) | bytes/s | Converted to bytes/s, divider = 1 |
126
+| Seconds, ms, µs, ns | seconds | Stored as nanoseconds, divider = 1 000 000 000 |
127
+| Percent (`%`) | % | Value ×1000, divider = 1000 |
128
+| Counters (`c`) | c | Stored as-is |
129
+| Any other unit or unitless | original text | Value ×1000, divider = 1000 |
130
+
131
+When a plugin flips between `KB` and `MB` (or `ms` and `s`) the collector still
132
+publishes a single chart in base units, so there are no spurious RRD resets. If
133
+a metric genuinely changes semantics (for example, from bytes to seconds) or a
134
+job’s cadence changes, scripts.d.plugin re-sends the CHART definition so Netdata
135
+can flush/recreate the series with the new metadata.
136
+
137
+The scheduler also exposes a `nagios.scheduler.next` chart showing
138
+“time until the next job fires” in seconds (nanosecond precision). Expect it to
139
+track the configured intervals; spikes indicate the executor is falling behind
140
+(worker starvation, very long-running checks, etc.).
141
+
142
+### Cadence (`update_every`)
143
+
144
+Jobs follow the same cadence controls as go.d collectors: set `update_every`
145
+(seconds) inside each job definition to run faster or slower than the default
146
+60 s interval. When omitted, scripts.d picks a conservative default (currently
147
+60 s). This field applies to both Nagios and Zabbix jobs so you can mirror your
148
+existing polling schedules.
149
+
150
+### Logging over OTLP (TLS support)
151
+
152
+Structured logs are forwarded to OTEL via `logging.otlp`. Besides `endpoint`,
153
+`timeout`, `tls`, and `headers`, you can now set:
154
+
155
+- `tls_ca`: custom CA bundle for the collector
156
+- `tls_cert` / `tls_key`: client certificate pair for mutual TLS
157
+- `tls_server_name`: override the TLS SNI when the collector name differs from the
158
+ endpoint host
159
+- `tls_skip_verify`: disable server certificate verification (not
160
+ recommended outside of lab environments)
161
+
162
+When `tls` is `true`, the plugin always establishes a TLS 1.2 connection using
163
+these settings. Set `tls: false` only for loopback collectors or other trusted
164
+plaintext networks.
165
+
166
+### LLD lifecycle
167
+
168
+Zabbix-style jobs keep their LLD catalogs and missing-instance counters in
169
+memory. Restarting the agent or reloading the plugin resets that state, mirroring
170
+how go.d collectors reset transient discovery data. If you need longer retention,
171
+keep the plugin running continuously; no on-disk cache is maintained.
172
+
173
+### Zabbix preprocessing
174
+
175
+Dependent pipelines share the same `.steps` schema as the standalone
176
+`zabbix-preproc` library. Step `type` accepts human-readable tokens such as
177
+`jsonpath`, `csv_to_json`, or `snmp_walk_value`. The optional `error_handler`
178
+field understands the native Zabbix actions: `default`, `discard`, `set-value`,
179
+and `set-error`. When you choose `set-value` or `set-error` provide the fallback
180
+text via `error_handler_params`.
181
+
182
+### Mock integration tests
183
+
184
+A small suite of mock Nagios plugins lives under `tests/plugins/`. They exercise
185
+state handling, perfdata parsing, macro substitution, long output logging, and
186
+skip semantics without requiring external services. Run them with:
187
+
188
+```bash
189
+cd src/go
190
+go test ./plugin/scripts.d/tests
191
+```
192
+
193
+The tests stub `nd-run`, execute the mock scripts through the scheduler, and
194
+assert the emitted metrics/logs. Extend this suite whenever you add new
195
+collector features so we keep a fast end-to-end signal in CI.
196
+
197
+## Building
198
+
199
+Enable the plugin during CMake configuration:
200
+
201
+```bash
202
+cmake -DENABLE_PLUGIN_SCRIPTS=On ..
203
+cmake --build . --target scripts-plugin
204
+```
205
+
206
+The resulting binary lives at `usr/libexec/netdata/plugins.d/scripts.d.plugin`.
207
+Stock configuration ships in `usr/lib/netdata/conf.d/scripts.d/`.

+ metrics_description: |
28
+ This module runs unmodified [Nagios plugins](https://www.nagios-plugins.org/) inside Netdata without any changes to the plugins themselves.
29
+
30
+ For each configured job it collects:
31
+
32
+ - **Check state**: OK / WARNING / CRITICAL / UNKNOWN (with soft/hard state tracking).
33
+ - **Performance data**: Every `label=value;warn;crit;min;max` metric emitted by the plugin is parsed and charted automatically, with unit normalization where possible.
34
+ - **Execution telemetry**: Runtime duration, scheduling latency, CPU time, peak RSS memory, and disk I/O per job.
35
+ - **Scheduler health**: Running / queued / scheduled job counts and throughput rates.
36
+ method_description: |
37
+ Jobs are executed via `nd-run` (the Netdata unprivileged helper) at the configured `check_interval`.
38
+ Standard Nagios macros (`$HOSTADDRESS$`, `$ARG1$`, `$USERn$`, etc.) are expanded before execution.
39
+ Plugin output is parsed according to the [Nagios Plugin API](https://nagios-plugins.org/doc/guidelines.html):
40
+ the first line provides the status and optional performance data after the `|` separator.
41
+ default_behavior:
42
+ auto_detection:
43

44
+ No auto-detection. Each job must be explicitly configured with a `plugin` path pointing to the Nagios plugin executable.

214
+ ### Virtual Node Label Conventions
215
+
216
+ When a job references a `vnode`, the module reads Nagios macros from the virtual node's **labels** using prefix conventions:
217
+
218
+ | Label key | Nagios macro | Environment variable | Description |
219
+ |-----------|-------------|---------------------|-------------|
220
+ | `_address` | `$HOSTADDRESS$` | `NAGIOS_HOSTADDRESS` | IP address or DNS name of the host |
221
+ | `_alias` | `$HOSTALIAS$` | `NAGIOS_HOSTALIAS` | Human-readable host alias |
222
+ | `_VARNAME` | `$_HOSTVARNAME$` | `NAGIOS__HOSTVARNAME` | Custom host variable (any `_` prefixed key except `_address` and `_alias`) |
223
+ | `key` | `$_HOSTLABEL_KEY$` | `NAGIOS__HOSTLABEL_KEY` | Regular label (no `_` prefix) |
224
+
225
+ Example vnode configuration (`/etc/netdata/vnodes/hosts.yaml`):
226
+
227
+ ```yaml
228
+ - hostname: web-server-1
229
+ guid: 12345678-1234-1234-1234-123456789abc
230
+ labels:
231
+ _address: "192.168.1.10"
232
+ _alias: "Web Server 1"
233
+ _DATACENTER: "us-east-1"
234
+ role: "frontend"
235
+ environment: "production"
236
+ ```
237
+
238
+ This produces:
239
+
240
+ | Macro | Value |
241
+ |-------|-------|
242
+ | `$HOSTADDRESS$` | `192.168.1.10` |
243
+ | `$HOSTALIAS$` | `Web Server 1` |
244
+ | `$_HOSTDATACENTER$` | `us-east-1` |
245
+ | `$_HOSTLABEL_ROLE$` | `frontend` |
246

+ The scheduler module manages the execution of jobs defined by the nagios and zabbix modules.
30
+
31
+ It provides:
32
+
33
+ - **Worker pool**: Concurrent execution with configurable worker count and queue depth.
34
+ - **OTLP logging**: Optional structured log export via gRPC for job execution results.
35
+
36
+ Scheduler-level metrics (jobs status, throughput, next run time) are exposed through the nagios and zabbix modules that use it.
37
+ method_description: |
38
+ The scheduler manages per-job timers and dispatches jobs to a worker pool.
39
+ Each worker executes a job via the configured runner (nagios or zabbix) and reports results back.

26
+ metrics_description: |
27
+ This module runs Zabbix-style data collection jobs natively inside Netdata.
28
+
29
+ It supports Zabbix's master-item + dependent-pipeline pattern: a single collection step
30
+ (command, HTTP, or SNMP) produces raw data, and one or more **preprocessing pipelines**
31
+ extract individual metrics using Zabbix-compatible preprocessing steps (JSONPath, regex,
32
+ JavaScript, SNMP walk, Prometheus parsing, CSV, XPath, and more).
33
+
34
+ For each configured job it collects:
35
+
36
+ - **User-defined metrics**: Each dependent pipeline produces a charted metric with configurable context, unit, family, chart type, and dimension algorithm.
37
+ - **Job state**: OK / WARNING / ERROR / UNKNOWN state tracking per job and per discovered instance.
38
+ - **Low-level discovery (LLD)**: Optional discovery pipelines that dynamically create instances from JSON arrays, similar to Zabbix LLD.
39
+ method_description: |
40
+ Collection supports three modes:
41
+
42
+ - **Command**: Runs an external script/binary via `nd-run` and captures stdout.
43
+ - **HTTP**: Performs an HTTP request and captures the response body.
44
+ - **SNMP**: Queries an SNMP agent (GET or WALK) and captures the result.
45
+
46
+ The raw output is then processed through Zabbix-compatible preprocessing steps to extract metrics.
47
+ Zabbix macros (`{HOST.NAME}`, `{HOST.IP}`, `{#MACRO}`, etc.) are expanded before execution.

+ ### Virtual Node Label Conventions
188
+
189
+ When a job references a `vnode`, the module reads Zabbix host macros from the virtual node's **labels** using prefix conventions:
190
+
191
+ | Label key | Zabbix macro | Description |
192
+ |-----------|-------------|-------------|
193
+ | `_address` | `{HOST.IP}`, `{HOST.CONN}` | IP address or DNS name of the host |
194
+ | `_alias` | `{HOST.ALIAS}` | Human-readable host alias |
195
+ | Other `_` prefixed | N/A | Reserved for future use |
196
+
197
+ The `{HOST.NAME}`, `{HOST.HOST}`, and `{HOST.DNS}` macros are derived from the vnode hostname.

1
+# Zabbix Preprocessing Library - API Design Specification
2
+
3
+**Last Updated:** 2025-11-14
4
+**Status:** Authoritative Requirements
5
+
6
+---
7
+
8
+## USER REQUIREMENTS (FINAL - DO NOT CHANGE)
9
+
10
+### Input Parameters
11
+The Netdata plugin will provide **TWO parameters**:
12
+1. **Unique identifier** for continuity (state tracking)
13
+2. **Just collected value** (the data to preprocess)
14
+
15
+### State Management
16
+- Library **MUST** maintain state based on the unique identifier
17
+- Unique identifier is **unique per shard, NOT across shards**
18
+- Example: "item1" in shard "A" is different from "item1" in shard "B"
19
+
20
+### Output Format
21
+The returned value of any collected sample is:
22
+1. **Array of metrics** (optionally with labels)
23
+2. **Possibly logs/events** to be committed to logs
24
+3. **Structured errors** for the caller to handle and understand what happened
25
+
26
+### Implementation Authority
27
+**Everything else is implementation details that the library author decides.**
28
+
29
+---
30
+
31
+## IMPLEMENTATION DECISIONS (CLAUDE'S AUTHORITY)
32
+
33
+### API Design Decision
34
+
35
+**Chosen Approach:** Explicit itemID parameter + Result struct return
36
+
37
+```go
38
+// Execute processes a single preprocessing step for a specific item
39
+func (p *Preprocessor) Execute(itemID string, value Value, step Step) (Result, error)
40
+
41
+// ExecutePipeline processes multiple steps for a specific item
42
+func (p *Preprocessor) ExecutePipeline(itemID string, value Value, steps []Step) (Result, error)
43
+
44
+// Result contains the output of preprocessing
45
+type Result struct {
46
+ Metrics []Metric // Array of extracted metrics
47
+ Logs []string // Optional log entries (future use)
48
+ Error error // Overall error if preprocessing failed
49
+}
50
+
51
+// Metric represents a single metric output
52
+type Metric struct {
53
+ Name string // Metric name
54
+ Value string // Metric value
55
+ Type ValueType // Value type
56
+ Labels map[string]string // Optional labels
57
+}
58
+```
59
+
60
+**Rationale:**
61
+1. **itemID parameter**: User said "unique identifier for continuity" and "just collected value" as TWO parameters
62
+2. **Result return**: User said "array of metrics" not single value
63
+3. **Error in Result**: Allows partial success (some metrics succeed, some fail)
64
+
65
+### State Key Format
66
+
67
+State keys will be: `"{shardID}:{itemID}:{operation}:{params_hash}"`
68
+
69
+- `shardID`: From NewPreprocessor(shardID)
70
+- `itemID`: From Execute(itemID, ...)
71
+- `operation`: "delta_value", "delta_speed", "throttle_value", "throttle_timed"
72
+- `params_hash`: Hash of step.Params for multi-param operations
73
+
74
+**Example:** `"shard1:item123:delta_value:"`
75
+
76
+### Thread Safety
77
+
78
+- State map already protected with sync.RWMutex (P0 #5 resolved)
79
+- itemID is per-call, no shared state
80
+- Multiple goroutines can call Execute() concurrently with different itemIDs
81
+
82
+### Migration Path
83
+
84
+**Phase 1 (Current):** Keep old API for backward compatibility
85
+```go
86
+// DEPRECATED: Use Execute(itemID, value, step) instead
87
+func (p *Preprocessor) execute(value Value, step Step) (Value, error) {
88
+ // Calls Execute("", value, step) - empty itemID = global state
89
+}
90
+```
91
+
92
+**Phase 2 (After Netdata integration):** Remove deprecated API
93
+
94
+### Multi-Metric Extraction
95
+
96
+Currently, preprocessing operations return single values. Multi-metric extraction (JSONPath arrays, Prometheus scrapes, CSV rows) will be:
97
+
98
+**Phase 1 (Current):** Single metric in array
99
+```go
100
+Result{
101
+ Metrics: []Metric{{Name: "", Value: "result", Type: ValueTypeStr}},
102
+}
103
+```
104
+
105
+**Phase 2 (Future):** Actual multi-metric extraction
106
+```go
107
+// JSONPath with array result
108
+Result{
109
+ Metrics: []Metric{
110
+ {Name: "metric1", Value: "10", Labels: map[string]string{"index": "0"}},
111
+ {Name: "metric2", Value: "20", Labels: map[string]string{"index": "1"}},
112
+ },
113
+}
114
+```
115
+
116
+### Persistence API
117
+
118
+**Deferred to Phase 3** - not needed for initial Netdata integration:
119
+```go
120
+// SaveState exports preprocessor state for persistence
121
+func (p *Preprocessor) SaveState() ([]byte, error)
122
+
123
+// LoadState imports preprocessor state from persistence
124
+func (p *Preprocessor) LoadState(data []byte) error
125
+```
126
+
127
+**Rationale:** Netdata can recreate preprocessor instances on restart. State loss acceptable for now.
128
+

+
131
+## IMPLEMENTATION CHECKLIST
132
+
133
+**Current Status:** Ready to implement P0 #3
134
+
135
+### Tasks:
136
+1. ✅ Document requirements (this file)
137
+2. ⏳ Add itemID parameter to Execute() and ExecutePipeline()
138
+3. ⏳ Update state key generation to use shardID + itemID
139
+4. ⏳ Change return type from (Value, error) to (Result, error)
140
+5. ⏳ Update all step functions to return Result
141
+6. ⏳ Keep deprecated execute() for backward compatibility
142
+7. ⏳ Update all 362 test cases to use new API
143
+8. ⏳ Add tests for per-item state isolation
144
+9. ⏳ Verify all tests still pass (362/362)

+## NOTES FOR FUTURE SESSIONS
151
+
152
+**If discussing API design again:**
153
+- **STOP** - Read this file first
154
+- Requirements are FINAL (from user)
155
+- Implementation decisions are FINAL (from Claude)
156
+- Just implement, don't debate
157
+
158
+**If user requests changes:**
159
+- Update this file with new requirements
160
+- Mark as FINAL
161
+- Implement
162
+
163
+**If API questions arise:**
164
+- Refer to "IMPLEMENTATION DECISIONS" section
165
+- Make decision, document, implement
166
+- Don't ask user unless truly ambiguous

+## BACKWARD COMPATIBILITY NOTES
171
+
172
+**Breaking Changes:**
173
+1. Execute() signature changes: `(value, step)` → `(itemID, value, step)`
174
+2. Return type changes: `(Value, error)` → `(Result, error)`
175
+
176
+**Migration:**
177
+```go
178
+// Old code:
179
+result, err := p.Execute(value, step)
180
+
181
+// New code:
182
+result, err := p.Execute("item123", value, step)
183
+// result is now Result{Metrics: []Metric{...}}
184
+```
185
+
186
+**Compatibility Layer:**
187
+- Keep old execute() as private method
188
+- Old tests can use it temporarily
189
+- Remove after Netdata integration complete
190
+
191
+---
192
+
193
+## REJECTED ALTERNATIVES
194
+
195
+**Why not add itemID to Value struct?**
196
+- User said TWO parameters: identifier + value
197
+- Pollutes Value with state management concerns
198
+- Less explicit than parameter
199
+
200
+**Why not SetItemContext()?**
201
+- Not thread-safe without locking
202
+- Awkward for concurrent processing
203
+- Violates "explicit is better than implicit"
204
+
205
+**Why not per-item Preprocessor instances?**
206
+- Memory overhead (one instance per item)
207
+- Complex lifecycle management
208
+- User said "unique identifier for continuity" not "instance per item"
209
+
210
+**Why not return ([]Metric, error)?**
211
+- Need structured errors AND logs in future
212
+- Result struct allows extension without API changes
213
+- Matches user requirement for "logs/events"

13
+## Installation
14
+
15
+```bash
16
+go get github.com/netdata/zabbix-preproc
17
+```
18
+
19
+## Quick Start
20
+
21
+```go
22
+package main
23
+
24
+import (
25
+ "fmt"
26
+ preproc "github.com/netdata/zabbix-preproc"
27
+)
28
+
29
+func main() {
30
+ // Create preprocessor for a shard
31
+ p := preproc.NewPreprocessor("shard1")
32
+
33
+ // Define preprocessing pipeline
34
+ steps := []preproc.Step{
35
+ {Type: preproc.StepTypeJSONPath, Params: "$.cpu"},
36
+ {Type: preproc.StepTypeMultiplier, Params: "100"},
37
+ }
38
+
39
+ // Process value
40
+ value := preproc.Value{Data: `{"cpu": 0.45}`}
41
+ result, err := p.ExecutePipeline("cpu_metric", value, steps)
42
+ if err != nil {
43
+ panic(err)
44
+ }
45
+
46
+ // Get result
47
+ fmt.Println(result.Metrics[0].Value) // Output: 45
48
+}
49
+```
50
+
51
+## Validation
52
+
53
+Validate steps before execution to catch configuration errors early:
54
+
55
+```go
56
+// Validate a single step
57
+step := preproc.Step{Type: preproc.StepTypeMultiplier, Params: "2.5"}
58
+if err := preproc.ValidateStep(step); err != nil {
59
+ // Handle validation error
60
+ fmt.Printf("Invalid step: %v\n", err)
61
+}
62
+
63
+// Validate entire pipeline
64
+steps := []preproc.Step{
65
+ {Type: preproc.StepTypeJSONPath, Params: "$.cpu"},
66
+ {Type: preproc.StepTypeMultiplier, Params: "100"},
67
+}
68
+if err := preproc.ValidatePipeline(steps); err != nil {
69
+ // Pipeline has invalid configuration
70
+ fmt.Printf("Invalid pipeline: %v\n", err)
71
+}
72
+```
73
+
74
+**Benefits of early validation:**
75
+- Catch configuration errors before processing data
76
+- Especially useful for multi-step pipelines (fail fast)
77
+- Clear error messages indicating which parameter is missing/invalid
78
+- Validates step type, required parameters, parameter format, and error handlers

80
+## Common Use Cases
81
+
82
+### 1. Data Extraction
83
+
84
+**JSONPath** - Extract values from JSON:
85
+```go
86
+steps := []preproc.Step{
87
+ {Type: preproc.StepTypeJSONPath, Params: "$.server.memory"},
88
+}
89
+// Input: {"server": {"memory": 8192}}
90
+// Output: 8192
91
+```
92
+
93
+**XPath** - Extract values from XML:
94
+```go
95
+steps := []preproc.Step{
96
+ {Type: preproc.StepTypeXPath, Params: "//temperature/text()"},
97
+}
98
+// Input: <data><temperature>25.5</temperature></data>
99
+// Output: 25.5
100
+```
101
+
102
+**Prometheus** - Extract specific metrics:
103
+```go
104
+steps := []preproc.Step{
105
+ {Type: preproc.StepTypePrometheusPattern, Params: `http_requests{method="GET"}`},
106
+}
107
+// Input: http_requests{method="GET"} 1027\nhttp_requests{method="POST"} 50
108
+// Output: 1027
109
+```
110
+
111
+### 2. Data Transformation
112
+
113
+**Multiply** - Scale values:
114
+```go
115
+steps := []preproc.Step{
116
+ {Type: preproc.StepTypeMultiplier, Params: "1000"},
117
+}
118
+// Input: 1.5
119
+// Output: 1500
120
+```
121
+
122
+**Regex Substitution** - Transform text:
123
+```go
124
+steps := []preproc.Step{
125
+ {Type: preproc.StepTypeRegexSubstitution, Params: "([0-9]+)\n$1 units"},
126
+}
127
+// Input: Temperature: 25
128
+// Output: Temperature: 25 units
129
+```
130
+
131
+**Trim** - Remove whitespace:
132
+```go
133
+steps := []preproc.Step{
134
+ {Type: preproc.StepTypeTrim, Params: " \t\n"},
135
+}
136
+// Input: " hello "
137
+// Output: "hello"
138
+```
139
+
140
+### 3. Stateful Operations
141
+
142
+**Delta Value** - Calculate differences:
143
+```go
144
+steps := []preproc.Step{
145
+ {Type: preproc.StepTypeDeltaValue},
146
+}
147
+// First call: 100 → 0 (baseline)
148
+// Second call: 150 → 50 (delta)
149
+```
150
+
151
+**Delta Speed** - Calculate rate per second:
152
+```go
153
+steps := []preproc.Step{
154
+ {Type: preproc.StepTypeDeltaSpeed},
155
+}
156
+// Call 1 (t=0s): 100 bytes → 0
157
+// Call 2 (t=10s): 600 bytes → 50 bytes/sec
158
+```
159
+
160
+**Throttling** - Suppress duplicate values:
161
+```go
162
+steps := []preproc.Step{
163
+ {Type: preproc.StepTypeThrottleValue, Params: "300"}, // 5 minutes
164
+}
165
+// Only processes value if changed or 5 min elapsed
166
+```
167
+
168
+### 4. Multi-Metric Extraction
169
+
170
+**Prometheus to Multiple Metrics**:
171
+```go
172
+steps := []preproc.Step{
173
+ {Type: preproc.StepTypePrometheusToJSONMulti},
174
+}
175
+
176
+prometheusData := `
177
+http_requests{method="GET"} 100
178
+http_requests{method="POST"} 50
179
+memory_bytes 8192
180
+`
181
+
182
+result, _ := p.ExecutePipeline("metrics", preproc.Value{Data: prometheusData}, steps)
183
+
184
+for _, metric := range result.Metrics {
185
+ fmt.Printf("%s: %s (labels: %v)\n", metric.Name, metric.Value, metric.Labels)
186
+}
187
+// Output:
188
+// http_requests: 100 (labels: map[method:GET])
189
+// http_requests: 50 (labels: map[method:POST])
190
+// memory_bytes: 8192 (labels: map[])
191
+```
192
+
193
+**SNMP Walk to Multiple Metrics**:
194
+```go
195
+steps := []preproc.Step{
196
+ {Type: preproc.StepTypeSNMPWalkToJSONMulti, Params: ".1.3.6.1.2.1.2.2.1.2"},
197
+}
198
+
199
+snmpData := `
200
+.1.3.6.1.2.1.2.2.1.2.1 = STRING: "eth0"
201
+.1.3.6.1.2.1.2.2.1.2.2 = STRING: "eth1"
202
+`
203
+
204
+result, _ := p.ExecutePipeline("interfaces", preproc.Value{Data: snmpData}, steps)
205
+// Returns multiple metrics with OID indices as labels
206
+```
207
+
208
+**JSONPath to Multiple Values**:
209
+```go
210
+steps := []preproc.Step{
211
+ {Type: preproc.StepTypeJSONPathMulti, Params: "$.servers[*].cpu"},
212
+}
213
+
214
+jsonData := `{"servers": [{"cpu": 45}, {"cpu": 23}, {"cpu": 78}]}`
215
+
216
+result, _ := p.ExecutePipeline("cpus", preproc.Value{Data: jsonData}, steps)
217
+// Returns 3 metrics with values: 45, 23, 78
218
+```
219
+
220
+### 5. Error Handling
221
+
222
+**Discard on Error**:
223
+```go
224
+steps := []preproc.Step{
225
+ {
226
+ Type: preproc.StepTypeJSONPath,
227
+ Params: "$.nonexistent",
228
+ ErrorHandler: preproc.ErrorHandler{
229
+ Action: preproc.ErrorActionDiscard,
230
+ },
231
+ },
232
+}
233
+// Returns empty result instead of error
234
+```
235
+
236
+**Set Custom Value on Error**:
237
+```go
238
+steps := []preproc.Step{
239
+ {
240
+ Type: preproc.StepTypeValidateRange,
241
+ Params: "0\n100",
242
+ ErrorHandler: preproc.ErrorHandler{
243
+ Action: preproc.ErrorActionSetValue,
244
+ Params: "-1", // Default value
245
+ },
246
+ },
247
+}
248
+// Returns -1 if value out of range
249
+```
250
+
251
+### 6. Complex Pipelines
252
+
253
+Chain multiple steps together:
254
+
255
+```go
256
+steps := []preproc.Step{
257
+ // 1. Extract JSON value
258
+ {Type: preproc.StepTypeJSONPath, Params: "$.temperature"},
259
+
260
+ // 2. Remove whitespace
261
+ {Type: preproc.StepTypeTrim, Params: " "},
262
+
263
+ // 3. Extract number (remove unit)
264
+ {Type: preproc.StepTypeRegexSubstitution, Params: "([0-9.]+).*\n\\1"},
265
+
266
+ // 4. Convert Celsius to Fahrenheit
267
+ {Type: preproc.StepTypeMultiplier, Params: "1.8"},
268
+}
269
+
270
+value := preproc.Value{Data: `{"temperature": " 25.0 C "}`}
271
+result, _ := p.ExecutePipeline("temp", value, steps)
272
+// Output: 45

326
+## Architecture
327
+
328
+### Per-Shard State Isolation
329
+
330
+Each preprocessor instance maintains independent state:
331
+
332
+```go
333
+// Shard A - processing metrics from server1
334
+p1 := preproc.NewPreprocessor("shard-server1")
335
+
336
+// Shard B - processing metrics from server2
337
+p2 := preproc.NewPreprocessor("shard-server2")
338
+
339
+// Each maintains separate delta/throttle history
340
+// No state leakage between shards
341
+```
342
+
343
+### Thread Safety
344
+
345
+All operations are thread-safe:
346
+- Concurrent preprocessing across different items/shards
347
+- VM pooling for JavaScript execution
348
+- Read-only MIB-to-OID mappings
349
+- RWMutex protection for stateful operations
350
+
351
+### Performance Optimizations
352
+
353
+- **VM Pooling**: JavaScript VMs reused, not recreated
354
+- **Program Caching**: Compiled JavaScript programs cached
355
+- **Regex Caching**: Patterns compiled once at package init
356
+- **strings.Builder**: Efficient string construction in loops
357
+

221
+// - Supports multi-byte UTF-8 delimiters and quote characters (not just single runes)
222
+// - Special mode when delimiter == quote (disables quoting behavior entirely)
223
+// - Strict validation: rejects \n\r line breaks, unclosed quotes, invalid characters after closing quotes
224
+// - UTF-8 validation: returns error on invalid UTF-8 sequences
225
+//
226
+// Parameters:
227
+// - data: Raw CSV string data to parse
228
+// - delimiter: Field delimiter (can be multi-byte UTF-8 string like "€")
229
+// - quote: Quote character (can be multi-byte UTF-8 string like "§")

231

+// parseSNMPWalk parses SNMP walk text output and extracts value for target OID.
778
+//
779
+// This custom parser processes text output from the snmpwalk command-line tool
780
+// (not binary SNMP protocol data). It handles complex SNMP data formats including:
781
+// - Multiple value types: STRING, INTEGER, Hex-STRING, Timeticks, Counter32, etc.
782
+// - Multiline quoted strings with proper quote tracking
783
+// - Multiline hex strings with continuation lines
784
+// - MIB name to numeric OID translation
785
+// - "Wrong Type" warnings with type/value extraction
786
+// - NULL and empty string handling
787
+//
788
+// Example SNMP walk format:
789
+//
790
+// .1.3.6.1.2.1.1.1.0 = STRING: "Linux server 5.4.0"
791
+// .1.3.6.1.2.1.1.3.0 = Timeticks: (12345) 0:02:03.45
792
+//
793
+// Parameters:
794
+// - data: Text output from snmpwalk command (one or more OID=value lines)
795
+// - targetOID: OID to extract (supports MIB names like "SNMPv2-MIB::sysDescr.0")
796
+//
797
+// Returns:
798
+// - snmpEntry: Parsed entry containing OID, value type, and value
799
+// - error: Parsing error if format is invalid or target OID not found
800
