Logging thousend files via Splunk Forwarder causes high CPU load
Hi there,
we have a oracle logging directory with thousend .aud files for logging to Splunk.
Each day over 700 new files will be created.
We experience a heavy workload on the system caused by the splunkd process.
We think splunkd monitores ALL files and after some weeks a hugh bunch of filemonitoring threads are occuping the CPU.
How can we tell splunk not to monitor already indexed files and only have a look on new created. The closed file will never be changed anymore.
Our inputs.conf:
[monitor:///oracle/Q*/trace/audit/*.aud]
sourcetype=oracle:audit:text
whitelist = \w.+.aud
ignoreOlderThan=7d
index=oracle_sap
disabled = false

I think you have to create your own script to delete/move/rename the indexed files.

Hi,
How are your new files named? Any thing to differentiate new and old.

The naming doesn't seem to be helpful. Since new files are created every day, decrease ignoreOlderThan to 2 or 3 days. This can reduce load.
