Are you sure there are logs being sent?

uploaded the current logstash log

It looks again its not receiving logs, and though we provided enough ram and cpu, utilization seems to be very high. Always, cpu is higher than 150%.

While 150% isn't that high is you have several processors, which is causing that, ?

I've seen this before: I'd make absolutely certain the logs you're sending to syslog inputs are RFC3164 compliant. Or, alternatively, send the non-compliant logs to a generic tcp or udp input instead.

And based on these invalid formats, it is possible that the logs are being put into indexes with the incorrect dates.

Also, the error above is from Jun 18 which would be recorded in the index 3 weeks ago.
