mod-gearman |showing false device down

[progressive.nagiosXI]

Hi ,

when mod-gearman error occured we check logs and find below
1.on remote(worker) ,no error found in logs .
2.in Nagiosxi server no log generate at error time but only one error write in logs by nagiosxi,PFA

[tgriep]

Those errors suggest that the Gearman Server cannot connect to the worker.
If you run the following command on the Nagios server, it will show you what workers the Gearman server knows about.

Code: Select all

gearman_top2 -b

If one of the Queues have a lot of Jobs waiting, then that worker is not retrieving the checks so try and restart the worker to see if it starts to process the checks.

Hi ,

still we are not able to restart gearmand service manually in Nagiosxi.

Our Nagiosxi vendor (Nagios Technical Expert ) from where we purchased nagiosxi ,check our profile and gearmand logs and suggest below status.

"[Based on the log we have identified there is are issues in the configuration done for Mod-gearman.

Based on the Mod_gearman logs the worker is unable to find checks on the system and is restarting the same every time. We have to make the changes on the mod_gearmam end and do the reconfiguration]."

Nagios Team Please help for below steps :-
can we remove gearman and reinstall again with fresh setting in NagiosXi(please share documentation)
or
Help us to reset all configuration,version,modules etc

Thanks

If you want to continue on trying to get Mod Gearman Working, I will need the following files form all of the Gearman Workers and the Nagios server if they exist.

Code: Select all

/etc/mod_gearman2/worker.conf
/etc/mod_gearman2/module.conf
/var/log/gearmand/gearmand.log
/var/log/mod_gearman2/mod_gearman_neb.log
/var/log/mod_gearman2/mod_gearman_worker.log

And, you need to run these commands as root on the Nagios Server and post the output here.

Code: Select all

ps -ef
gearman_top2 -b

Unfortunately @tgriep is out today. Can you PM me the files?

[tgriep]

Do you have a remote Mod Gearman worker setup to process this hostgroup called HTMEDIA?
That worker seems to not be processing the jobs so you should try resetting the Mod Gearman worker on that server to see if it starts to process the jobs.

If that does not work, we will need to see the worker.conf file from that server and the /var/log/mod_gearman2/mod_gearman_worker.log file.

Thanks.

Hi ,

Thanks

The check_nwc_healts plugin is a fairly large perl script that does take a log od resources to run so on a large server that has a lot of them running, it would make the load fairly high.
Your worker is running a lot of those checks so that is normal.
You can try and find an alternative plugin that does not load the system as much or run the checks less frequently to help out on the load of the server.

Your PM did not include the worker.conf file from the Gearman Worker server and the /var/log/mod_gearman2/mod_gearman_worker.log file so I would need to see them to continue on.
