I'm running sanity test for almost 36 hours to check the behavior of new ELK server against Merticbeat,Kibana and ES ( I've installed last versions of ES,Kibana and Metricbeat ( nothing elase is running )
Java process is taken ~ 1.68%
Node process ( Kibana ) ~ 1.42%
And sometime rtkit-damon is reached 13% and most of time it isn't shown in Metricbeat.
My question is : what is this process and it's normal the above stat and why some time it reached ~13% from process utilization.
Environment : RHEL 7.2 ,Memory: 64 GB RAM, Processor: Intel Xeon Processor - Dual - 8 cores - 2.8GHz
