We're troubleshooting an issue in our cluster and came across the following in \_nodes/hot\_threads. ``` 87.3% (436.2ms out of 500ms) cpu usage by thread 'elasticsearch[host1.domain.com][marvel.exporters]' ``` The above is showing up rather frequently, and I'm not sure what to make of it. I don't think it's the root cause of the issue, but I'm not sure I fully understand what it's doing. Any guidance would be appreciated. Thanks. ---

Are you logging your Marvel data into the same cluster? Cause if you are then that's why, take a look [here](https://www.elastic.co/guide/en/marvel/current/_installation.html#_installing_a_secondary_monitoring_cluster) for best practises. ---

@warkolm Thanks for the link. I'll have to look into a monitoring cluster for sure. ---
