#Semaphore statistics

Plugin: windows.plugin Module: PerflibObjects

#Overview

Inter-Process Communication (IPC) enables different processes to communicate and coordinate with each other. This collector monitors IPC semaphores, which are synchronization tools that:

• Control access to shared resources (like files, memory, or devices).
• Ensure only one process can access a resource at a time.
• Prevent conflicts between competing processes.

It queries for the 'Objects' object from Perflib in order to gather the metrics.

This collector is only supported on the following platforms:

• windows

This collector only supports collecting metrics from a single instance of this integration.

#Default Behavior

#Auto-Detection

The collector automatically detects all of the metrics, no further configuration is required.

#Limits

The default configuration for this integration does not impose any limits on data collection.

#Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.

#Setup

#Prerequisites

No action required.

#via File

The configuration file name for this integration is netdata.conf. Configuration for this specific integration is located in the [plugin:windows:PerflibObjects] section within that file.

The file format is a modified INI syntax. The general structure is:

[section1]
    option1 = some value
    option2 = some other value

[section2]
    option3 = some third value

You can edit the configuration file using the edit-config script from the Netdata config directory.

sudo ./edit-config netdata.conf

#Examples

There are no configuration examples.

#Alerts

There are no alerts configured by default for this integration.

#Metrics

Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

#Per System

These metrics refer to the entire system.

This scope has no labels.

Metrics:

Metric	Dimensions	Unit
system.ipc_semaphores	semaphores	semaphores
system.ipc_mutexes	mutexes	mutexes
