Hi,
I have over 150+ UF and they all behave the same. splunkd CPU usage is about 5% but every hour it spikes, up to 50-60%. This has been going on for many months. I have AIX and Linux UF and they all behave the same.
If I do a fresh install, it doesn't do that. But over time, the spike starts to happen. Recently, to test, I upgraded two AIX UF from version 6.5.2 to 7.0.2.
On one, I wiped out the entire install folder, basically started from scratch. There is no more spike on this one (but only a matter of time before it does it again).
On another, I simply upgraded over the existing install. The spike remained the same.
Something in splunkd is using more CPU over time, every hour. I would like to know what it is so I can possibly disable/play with it. splunkd CPU usage on my servers needs to be as low as possible.
Are people using UF on AIX and Linux seeing this too?
Below: UF that I wiped clean before reinstalling. We can see the spikes stoping after fresh install.
