    Description

      For the monitoring of our Kubernetes cluster I configured everything according to these instructions:

      https://www.zabbix.com/de/integrations/kubernetes

      At first it discovered everything just fine.

      Now that everything is discovered, if the host with the "Kubernetes nodes by HTTP" template is enabled there are many problems:

      • Data gathering for all hosts just stops, even for non Kubernetes hosts
      • One preprocessing worker runs non stop with 100% CPU utilization
      • After a while the preprocessing manager also runs on 100% CPU
      • RAM filling up over time with the preprocessing manager
      • No other preprocessing worker seems to do anything

      This goes on endlesly if I don't disable this host and restart the server.

      When the host is disabled everything else runs smoothly.

       

      I tried different amounts of preprocessing workers and gave the server more RAM to test if it helps but the problems stay the same.
