we have 2 DC(data center) and in each DC we have 26 servers.
We have configured elk on all servers.
We could see filebeat is sending data to logstash from all servers.
While checking in kibana, we are not seeing logs from 1 DC(13 servers) and remaining 39 servers logs we are able to see in kibana.
I have checked the trans_log and found that those 13 servers logs are not present in that.
Can you please provide your input.
What could be the cause?
