Splunk Add-on for Unix and Linux - rlog script not working?

Path Finder

I'm trying to get auditd events into Splunk using the script from the Splunk Add-on for Unix and Linux. It isn't working.

The audit logs are not being ingested. No errors are appearing in index=_internal for the host. It is successfully scheduled through the ExecProcessor component:

0400 INFO ExecProcessor [1975905 ExecProcessor] - New scheduled exec process: /opt/splunkforwarder/etc/apps/Splunk_TA_nix_l1_inputs/bin/

To attempt to address the problem I have done the following:

  1. Had the host owner ensure dependent utilities are installed (listed in
  2. Had the host owner change the log_group from root to splunk in /etc/audit/auditd.conf (suggested in

When executing rlog in debug mode (./ --debug) we get the following output:

  • As splunk user:
    Blank output
  • As root user:
    Expected output

Additional details:

  • This host was recently rebuilt. Before the rebuild the audit logs on this host were ingesting successfully through the Add-On.
  • Other scripts through the Add-On are working on this host.
  • This problem has not materialized on any of our other hosts utilizing the Add-On.

Thanks in advance for your input!
