This warning is actually not important for ausearch/report, but is meaningful for auditd. What this means is that you have incremental flushing halfway setup. Meaning that the value is non-zero as if you intended to flush periodically, but you don't actually have incremental selected as the flushing technique. The fix is to either select incremental as the flushing technique or set freq to 0 so that its consistent with the flush technique. The reason that you would want to use incremental flushing is for performance. I'd recommend 100 or 200 for the freq setting on a busy or aggregating server. I'd recommend 50 for everyone else. > I do not fully understand the impact of what the flush parameter.

It means you may not be getting the logging performance that you intended. -Steve -- Linux-audit mailing list [email protected] https://www.redhat.com/mailman/listinfo/linux-audit
