Shoot. I just reset the subsystem thinking maybe there was a stuck job or something.

Before I did that though, it reported the following for snapshots_maintenance. The Job Status was Waiting, the Last Run Status was SUCCESS, the Last Run Time was last night at 22:30:xx and the Next Run Time was 3 days from yesterday.

Attached is a screen shot of the audit log for type = BACKUP.

Are new indices written directly to the Log Repository or do they get moved over during the snapshot_maintenance process?

I'm looking at my repository and I don't see any new indices after 9/17. I think that's why my local storage is being consumed on each Log Server. The indices are not being created/moved to the repository.

Need to figure this out ASAP or I'm going to run out of storage over the weekend. Please help.

New indices are not written directly to the repo. They are stored locally and then moved over during maintenance.

Sometime a bad backup will cause problems and can be identified by a 0 byte file in the repo. Review the contents of the repo with "ls -alh /nlsrepcc'.

Do you see any curator jobs running if you run "ps aux | grep curator" ?

If you don't see anything running, tail the jobs.log while you then force the snapshots_maintenance job to run:

Code: Select all

tail -f /usr/local/nagioslogserver/var/jobs.log
Let us know if this produces any errors.

I don't see any errors, but the snapshot was not created. It looks like it ended right after the job was started.

There appears to be an issue with a urllib3 python package that got installed. Run the following to remove it and install one that should work:

Code: Select all

pip uninstall urllib3
yum install python-urllib3
Then run the maintenance job again while tailing the jobs.log to make sure it works.

It appears to be running now. Thank you!

Do I need to be worried about these errors?

You likely have a lot of indices that have backed up and resulting in a few timeouts. I wouldn't be too worried about this now as long as things are getting deleted and moved over to the repo. If they continue into next week we can check into it.

Good morning, it looks like the snapshot that ran on Friday completed successfully, so we're back up and running.

Thanks for your support as always.
