I have several Elastic Searches clusters in several Kubernetes Clusters.
Several VMs are sending the logs through filebeat to Logstash.
Some logs show very wired pattern.
The following graph shows that the number of transactions from one machine.
As you see, the logs are coming from 7:00 pm for few hours.
Log rotator create a new file at 7:00 pm.
I don't know where to look at for this issue. Any suggestions are welcomed.
Please help me to resolve this issue.
