# Socket statistics Plugin: proc.plugin Module: /proc/net/sockstat ## Overview This integration provides socket statistics. This collector is supported on all platforms. This collector supports collecting metrics from multiple instances of this integration, including remote instances. ### Default Behavior #### Auto-Detection This integration doesn't support auto-detection. #### 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. ## 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 Socket statistics instance This scope has no labels. Metrics: | Metric | Dimensions | Unit | |:------|:----------|:----| | ip.sockstat_sockets | used | sockets | | ipv4.sockstat_tcp_sockets | alloc, orphan, inuse, timewait | sockets | | ipv4.sockstat_tcp_mem | mem | KiB | | ipv4.sockstat_udp_sockets | inuse | sockets | | ipv4.sockstat_udp_mem | mem | sockets | | ipv4.sockstat_udplite_sockets | inuse | sockets | | ipv4.sockstat_raw_sockets | inuse | sockets | | ipv4.sockstat_frag_sockets | inuse | fragments | | ipv4.sockstat_frag_mem | mem | KiB | ## Alerts The following alerts are available: | Alert name | On metric | Description | |:------------|:----------|:------------| | [ tcp_orphans ](https://github.com/netdata/netdata/blob/master/health/health.d/tcp_orphans.conf) | ipv4.sockstat_tcp_sockets | orphan IPv4 TCP sockets utilization | | [ tcp_memory ](https://github.com/netdata/netdata/blob/master/health/health.d/tcp_mem.conf) | ipv4.sockstat_tcp_mem | TCP memory utilization | ## Setup ### Prerequisites No action required. ### Configuration #### File There is no configuration file. #### Options There are no configuration options. #### Examples There are no configuration examples.
