System socket_summary metricset

This functionality is experimental and may be changed or removed completely in a future release. Elastic will take a best effort approach to fix any issues, but experimental features are not subject to the support SLA of official GA features.

The System socket_summary metricset provides the summary of open network sockets in the host system.

It collects a summary of metrics with the count of existing TCP and UDP connections and the count of listening ports.

This metricset is available on:

  • FreeBSD
  • Linux
  • macOS


There are no configuration options for this metricset.


For a description of each field in the metricset, see the exported fields section.
