I am pretty new to ELK stack. We monitor a particular server health using ELK stack. We have Metricbeat which sends statics and based on that we have index created in Elastic. Kibana visualization is created based on this. But from last couple of days we get below error in Kibana.
We validated Index Management to check if we have data. We could find that there is no issue in streaming as we continue to receive data.
When tried to view the index from Discover, got below Request Timeout Error.
Any query we run in Dev Tools returns Internal Server Error, as like below.
We have ELK setup in dockerised env, ie, seperate docker for Elastic, Logstash and Kibana. When I restart the Kibana container alone, Kibana is back normal. But after sometime, I get this error again.
Tried below solution, but nothing positive.
What could be the reason. We are stuck with this for sometime. Thanks in advance
