Kibana CPU Load

Hi,

I am running a small single ELK instance just for visualizing some logs.

Because the process consumes around 12 % CPU when idle, I have tried to deactivate a few things in kibana.yml:

telemetry.enabled: false
xpack.fleet.enabled: false
xpack.securitySolution.enabled: false
xpack.uptime.enabled: false
xpack.apm.enabled: false
xpack.reporting.enabled: false
xpack.actions.enabledActionTypes: []

But that made no difference :(.

According to the logs, alerting and taskManager are still started. How can I deactivate these plugins?

What else could be causing the permanent load?

What are the specs of your server? Are you running anything else in the server besides Kibana?

Also, is this causing any issues? And by idle you mean that no one is accessing Kibana?

This looks like normal behavior, I don't think disabling those plugins will change anything.

It is a VM - the hypervisor is running on an Intel N100 SoC.

In that particular VM are Kibana + Logstash + single Elasticsearch running. It is just for visualizing firewall logs.

Yes, idle = no one is accessing Kibana.

It's not really a problem, but I'm wondering why Kibana seems to be permanently querying Elasticsearch.
