We have ELK cluster in Kubernetes and monitoring is enabled for Elasticsearch and was working fine. Today it stopped working.
Please find the monitoring chart of Kibana below.
Monitoring index for today ( .monitoring-es-7-2020.05.29) is there, but not much activity. Yesterday's index have about 1.2k docs per minute, but today only 40docs per minute and no chart.
Is there a way to check the monitoring status?
Where should I be looking for issues ?
