I have a Splunk Enterprise instance with a 1GB license set up to aggregate logs in a small Windows AD environment (Server 2016 DC, CentOS file server, and < 10 Win10 workstations). I currently have the DC, file server, and 3 workstations deployed. I keep getting license usage warnings. Upon investigation, the CentOS server where the Splunk server is installed is by far the largest license user (on average 200% usage). Furthermore, my linux_audit sourcetype is the main source of the usage. That sourcetype only monitors /var/log/audit/audit.log. On disk, /var/log/audit/audit.log is only 74MB, so I have no idea why I am using 2GB+ of license every single day! Can anyone help?
