HELP, its all stopped working!

I have just realised that no logs were received after 4.30 this morning.

All the services are up and running, I can access any old data no problem. Everything is working normally but no new log data?

We did have a disk space alert from Ubuntu which appears to have sorted itself out as we now have a few GB free. Has this affected something within Graylog?

All help more than welcome.

Hey @mr_m_cox,

is your disk usage still over the disk-level-watermark of elasticsearch? Default is 80% I think.
If yes, than your problem could be, that elasticsearch is not allowing a new index to be created because of too low disk space.

Take a look at system/overview in your Webinterface and look if your Elasticsearch is marked as green. Also, you could try curl -XGET localhost:9200/_cat/shards?h=index,shard,prirep,state,unassigned.reason| grep UNASSIGNED on your elasticsearch (change ip/port if needed) to see if any and which index is not assigned.

Greetings - Phil

This is my overview, the indexer issues have been there all along and I am yet to resolve but don’t appear to cause a direct problem to functionality like this has.

Sorry, I missed something. Try

curl -XGET "localhost:9200/_cat/shards?h=index,shard,prirep,state,unassigned.reason" --stderr - | grep "UNASSIGNED"

What does Graylog write in the Indexer Failure log?

Just prints nothing and returns to prompt.

Index Failure Log but as I said, its has been doing this all the time its been configured, not only since the 4.30 fail.

Well ok, what does the log file of your graylog-server say for the time since 4:30?

The button on the right saying “Pause Processing” was se to “Resume Processing”.

Now all works. would that have been a shutdown following disk space issues?

Tell a lie,I am getting messages in but not out. I have no sources or messages in the last few hours still, not even in the last 5 mins.

I have just had a google around and cant really find anything about why I would be getting input but no output.

I have cleared my journal as the journalreader service was stopped failed.

Any suggestions? Its clearly taking in messages but not outputting meaning all current time frame searches are empty and no sources.

UPDATE

Still broken. Got hundreds on ins and no outs.

Any advise or suggestions would be more than welcome. Everything looks set correctly in the web interface, just not happening

Have you tried restarting elasticsearch and graylog? This fixed it for me when I had the problem that the output wouldn’t restart after a full disk.

I have rebooted the box, restarted the graylog, elasticsearch and mongod services.

I think I have cleared the journal although a little unsure of the location. I dont know what else to do. It was working great yesterday, filled the disk overnight and now wont come back.

Arghh!

disk is now expanded, along with RAM to provide plenty of space now.

Can you provide your /var/log/graylog-server/server.log file or is this a security problem for your company?
