Slow indexing and large index


(J.L.) #1

For this environment i'm using ES + Logstash + GrayLog2

I've manually ( and stupidly ) deleted the elasticsearch indices in
/var/lib/elasticsearch/....

Then i've cleaned mongodb to reset the GL2 config

Logstash is reading logfiles and sending GELF output

In GL2 i created Inputs for UDP GELF

All is working fine BUT the indexing is now very slow, on average 50
messages per second.

I saw frequent numbers of over 2000 messages per second

What can i do to analyze, troubleshoot, fix this issue ?

Best Regards,

Joris
