OSquery is an operating system instrumentation framework for OS X, Linux, and FreeBSD. It enables you to gather a variety of system and monitoring information.
OSquery docs: http://osquery.readthedocs.io/en/stable/
Note: I use default directory locations for Splunk and OSquery
Splunk App Installation:
Install like a standard app in the Splunk 'apps' directory on your search head(s).
Splunk Forwarder Configuration:
[monitor:///var/log/osquery/osqueryd.results.log]
sourcetype = osqueryd.results
The searches are built off of the 'osqueryd.results' sourcetype. If you'd like to use a different sourcetype the dashboards will need to be updated. Plan to update this in the future.
