ELK stops accepting logs

[Danp]

@scottalanmiller Any idea where to implement this change?

Also found this Github issue.

Not sure if this is correct, but I added the line set LS_HEAP_SIZE=2g to /opt/logstash/bin/logstash.

Did it fire up? If so, probably right

Yes, it started. I just wasn't sure if this was the correct place to implement the change.

How would I verify that the heap size is now 2g?

[scottalanmiller]

How are you starting Logstash? If you look in /etc/init.d/logstash, the start script has the heap size hard coded there. If you are starting from the system, you will need to change it there, I'm sure.

[scottalanmiller]

Still up or has it crashed again?

[Danp]

Did it fire up? If so, probably right

So, my earlier change was not correct. Found this in the logstash.err file -- No such command "LS_HEAP_SIZE=2g" .

How are you starting Logstash?

I followed your instructions to build the ELK server, so everything is handled by systemd.

If you look in /etc/init.d/logstash, the start script has the heap size hard coded there. If you are starting from the system, you will need to change it there, I'm sure.

I missed that yesterday when I examined that file.Thanks!

Seems like there a memory leak somewhere. From logstash.err-20160316:

Error: Your application used more memory than the safety cap of 2G.
Specify -J-Xmx####m to increase it (#### = cap size in MB).
Specify -w for full OutOfMemoryError stack trace

@Danp Just as a similar item MineCraft FTB has a similar memory leak issue. I have yet to find a solution for it (among the the million of people talking about it around Google)

[Danp]

Ran a plugin update. Will see if that has any effect.

Updated logstash-codec-json 2.1.0 to 2.1.1
Updated logstash-filter-dns 2.0.2 to 2.1.0
Updated logstash-filter-json 2.0.3 to 2.0.4
Updated logstash-input-beats 2.1.3 to 2.2.0
Updated logstash-input-rabbitmq 3.1.4 to 3.3.0
Updated logstash-input-redis 2.0.2 to 2.0.3
Updated logstash-output-elasticsearch 2.5.1 to 2.5.3

[Danp]

During the command bin/plugin update, received the error

Error Bundler::InstallError, retrying 1/10
An error occurred while installing manticore (0.5.5), and Bundler cannot continue.
Make sure that `gem install manticore -v '0.5.5'` succeeds before bundling.

Discussions on similar issues can be found here and here.

Lots of reports on this, although I have a feeling that it might not be a leak but might be just "how much memory Logstash needs."

Try setting it to something high and see if it stops expanding.

I already went from 1g to 2g. I could be off base, but I suspect a memory leak b/c it runs for days before the OOM condition occurs. The only active feed is from my XO server, and that activity should be light.

Found this current Github discussion that describes the plugin update issue I ran into.

That would be the expected behaviour whether a leak or just hasn't fully grown yet.

[Danp]

Finally back up and running...

What did you do?

[Danp]

@scottalanmiller Reinstalled ruby-maven and manticore.
