Nagios Support Forum

Hi Team

Need your help regarding high CPU usage on our Nagios Log server
Post checking we found out it is causing due to Java Process.

As a workaround we are rebooting the server, post which Nagios Log server is functioning properly.

However this issue is happening frequently
Could you please provide permanent solutions for it, with proper steps.
Our current Nagios Log Server version is 2.1.6

Depending on things like the number of open indexes you have, and the influx rate of log entries, the Elasticsearch process can take up large amounts of CPU time as well as RAM. What are the specs on your system as far as number of CPU cores and RAM amount? Is this on a virtual or physical system? Also, the header lines from top would be helpful in addition to just these two.
