| 22 | ## Overview |
| 23 | |
| 24 | This integration provides metrics from the `netstat`, `snmp` and `snmp6` modules. |
| 25 | |
| 26 | |
| 27 | |
| 28 | This collector is supported on all platforms. |
| 29 | |
| 30 | This collector supports collecting metrics from multiple instances of this integration, including remote instances. |
| 31 | |
| 32 | |
| 33 | ### Default Behavior |
| 34 | |
| 35 | #### Auto-Detection |
| 36 | |
| 37 | This integration doesn't support auto-detection. |
| 38 | |
| 39 | #### Limits |
| 40 | |
| 41 | The default configuration for this integration does not impose any limits on data collection. |
| 42 | |
| 43 | #### Performance Impact |
| 44 | |
| 45 | The default configuration for this integration is not expected to impose a significant performance impact on the system. |

| 73 | ## Alerts |
| 74 | |
| 75 | |
| 76 | The following alerts are available: |
| 77 | |
| 78 | | Alert name | On metric | Description | |
| 79 | |:------------|:----------|:------------| |
| 80 | | [ 1m_tcp_syn_queue_drops ](https://github.com/netdata/netdata/blob/master/src/health/health.d/tcp_listen.conf) | ip.tcp_syn_queue | average number of SYN requests was dropped due to the full TCP SYN queue over the last minute (SYN cookies were not enabled) | |
| 81 | | [ 1m_tcp_syn_queue_cookies ](https://github.com/netdata/netdata/blob/master/src/health/health.d/tcp_listen.conf) | ip.tcp_syn_queue | average number of sent SYN cookies due to the full TCP SYN queue over the last minute | |
| 82 | | [ 1m_tcp_accept_queue_overflows ](https://github.com/netdata/netdata/blob/master/src/health/health.d/tcp_listen.conf) | ip.tcp_accept_queue | average number of overflows in the TCP accept queue over the last minute | |
| 83 | | [ 1m_tcp_accept_queue_drops ](https://github.com/netdata/netdata/blob/master/src/health/health.d/tcp_listen.conf) | ip.tcp_accept_queue | average number of dropped packets in the TCP accept queue over the last minute | |
| 84 | | [ tcp_connections ](https://github.com/netdata/netdata/blob/master/src/health/health.d/tcp_conn.conf) | ip.tcpsock | TCP connections utilization | |

| 93 | ## Metrics |
| 94 | |
| 95 | Metrics grouped by *scope*. |
| 96 | |
| 97 | The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels. |
| 98 | |
| 99 | |
| 100 | |
| 101 | ### Per Network statistics instance |
