LogServer 201451.4

Noticed today that my backups have stopped. I dont normally check these very often as I have been on other projects. Looks like the last listed indice is for August.

Logs do not show any errors..

Can someone point me in the right direction on where to look to see why this has stopped?

Without spending a ton of time debugging I would jump on recommending an upgrade. There have been vast improvements in the backup system since the release you're using:

https://assets.nagios.com/downloads/nag ... HANGES.TXT

VAST - I'd bet $1 that simply upgrading will 100% solve your issues.

I agree, and that is planned. However I want to make sure we have this function working properly before hand as we keep 7 days live. This was working fine.

I did fine a log I didn't look at before at /var/log/elasticsearch/ which I have attached.

Seeing this...

Code: Select all

I see this repeating many times.

The best log to look at isn't persistent.

Can you do a tail -f on /usr/local/nagioslogserver/var/jobs.log and then run your backup? The output there is likely going to be the most useful.

Also can we check the health of your indices?

Code: Select all

curl 'localhost:9200/_cluster/health?level=indices&pretty'

Thanks

Also I failed to mention this issue:

nlsoldindices.png

As you can see from the screenshot we have a source that seems to have it's system time off, or is sending old events. I can delete these and they will show up again within a few hours.

Since they are so far out of the index dates could this be causing the issue?

The 7 days limit works just fine with the normal daily indexes but leaves these two behind.

To the best of my limited knowledge, the indexes are based upon receipt timestamp, not having anything to do with a timestamp in the event. You have to write a filter if you want the @_timestamp field replaced, and even then I'm not sure it's possible.

I'm assuming that these indexes always have a fixed size? Or are they growing/shrinking when you delete them? If the time was really far off on a node I think we'd have a not-green cluster status. I'm really not sure what's going on. Take a look at their last modified date on the system:

Code: Select all

ls -l /usr/local/nagioslogserver/elasticsearch/data/907e60a9-dc29-411e-96e8-2dfe503e0867/nodes/0/indices

Posted: **Wed Nov 11, 2015 1:29 pm**

Will do.

Can we address the other information I provided for the current backup of indexes issues?

Posted: **Wed Nov 11, 2015 2:06 pm**

I'm not entirely convinced that the problems aren't related...

Posted: **Wed Nov 11, 2015 2:12 pm**

Here are the results on your command.

No the size will vary along with the date. Two days from now they will read 4-27 etc...
