Filebeat panic and exit?

filebeater · August 31, 2019, 12:49am

Hello, I got the following from stderr while running filebeat, and filebeat just exited.
any idea on why filebeat just dies?
thanks!

@filebeater thanks, I have edit your last comment to reformat the configuration, you can use the preformatted text option (</>) from the toolbar to format configuration and logs next time.

Regarding the logs, could you paste the whole logs? The ones you posted don't seem to contain the original error.

filebeater · September 4, 2019, 6:35pm

I found out it is due to "run out of the memory", Here are the logs:

One thing We find really surprising is that: filebeat consumed much more memory than expected:
we set "channel_buffer_size: 26222400" and we have 512 kafka partitions, which is ~13G in total,
however, it consumes up to 91G runtime: It quickly ramped up to using 91G of memory in a couple of minutes after filebeat restarted. BEATSVERSION=7.3.1 GOVERSION=1.12.9.
hmm, looking up filebeat documentation again, I am confused whether channel_buffer_size is per kafka partition or per kafka broker. If it was per kafka broker, it makes even less sense now, since filoebeat is only connected to "45" kafka brokers per filebeat log:

2019-09-04T20:52:15.672Z INFO kafka/log.go:53 client/brokers registered new broker #38457 at [hostname:port]

an earlier version of filebeat and GO (BEATSVERSION=6.1.3. GOVERSION=1.8.3) consumes up to 43G of memory, still much more than what we expected, but much less than a newer version of filebeat/go). Disclaimer: we did not have chance to verify whether the upgrade is due to GO version upgrade or Filebeat version upgrade or a combo of both.

@filebeater could you upload a memory profile?

You can enable profiling adding the -httpprof localhost:6060 flag to filebeat, and get a memory profile downloading http://localhost:6060/debug/pprof/heap.

filebeater · September 12, 2019, 4:59pm

btw, the above memory usage is observed in our production running. Since that incident, we have since rolled back the filebeat from 7.3 to 6.1.3, we have not observed in production since.
This is not readily repro in our experiment setup, i will keep an eye on this..
On a related note, this is from our experiment: filebeat existed right after start, complaining about:
out of memory: cannot allocate 209715200-byte block (9326067712 in use)
fatal error: out of memory
