System socket datasetedit

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.

This is the socket dataset of the system module.

It is implemented for Linux only.


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

Here is an example document generated by this dataset:
