System socket datasetedit

This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview 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.
