Hey, I'm relatively new to ES and am building out a cluster for some pretty heavy lifting. Throughout my whole process of building and troubleshooting this thing so far, there's been a pattern of spikes to almost 100% CPU load every 5 minutes on all of my nodes. The graph only shows it happening on some each time, but that's just the 1 minute check interval on my metrics agent not catching the short event on each node each time.
Can anyone help me identify what's causing this? Is it normal or something I should be trying to fix? I can tell you it's the Java process on the node doing it, not some other process.
What troubleshooting steps can I take? What info can I provide here? I did some struggling with X-Pack today but was not able to get it running (and trying is pretty disruptive). Is that the right tool?
I've been stuck at this for a couple days. Can anyone provide any input?
