Filebeat consuming disk space

ErSumit · November 26, 2018, 9:34am

Filebeat process is utilizing disk space. No clue why and where?
Whenever disk utilization reaches high, I restarted filebeat service and disk utilization reduced.
How can I fix this?

I have not changed much of default parameters
Filebeat is serving about 20 files 24*7 to logstash server

Please help!

kvch · November 26, 2018, 10:21am

Is is possible that Filebeat has too many open file handles? What is the output of lsof -c filebeat?

ErSumit · November 26, 2018, 12:41pm

Yes, kvch
In output of 'lsof -c filebeat' I can see files from last 4 days.

How can I fix this? In my case files are named as --YYYY.mm.dd.log
and files only of todays date will get updated.

But I can see this line in logfile
log/harvester.go:253 File is inactive: --YYYY.mm.dd.log. Closing because close_inactive of 5m0s reached.
don't this closes file open handler?

ErSumit · November 26, 2018, 12:46pm

Even I can see lines from file of 23rd Nov is processed today. I can see them on kibana dashboard -> Discover

Log Message of 23rd Nov is arrived to logstash and thus elasticsearch today(26th Nov). Even this is causing me in wrong data.
What could be the reason? Please help in this as well.

I have 5 instances of filebeat and 5 logstash instances, as well.
The cluster consist of 3 master + 2 data nodes
