Timeout in check_wmi_plus.pl

Hi guys,
It seems like the timeout set into the plugin check_wmi_plus.pl is ignored when the check is executed by modgearman.
Running the check in a gearman queue, we get a CRITICAL status with output "(Service Check Timed Out On Worker: ...)" and execution_time >=60s while without gearman, the same service go into UNKNOWN status with "UNKNOWN - Plugin Timed out (15 sec)".
Any idea about this behaviour?. We would like to executed those services through gearman with timeout=15s.
We are running Nagios XI 2012R2.9 and mod_gearman-1.4.14.
Thanks
Best Regards

Can you post the service config along with the other relevant configs (templates, commands, etc.)? Also, post the "mod_gearman_worker.conf". Hide sensitive info.

I might be wrong here but it looks like you have your check_wmi_plus command defined with a hardcoded timeout of 15 secs
Code: Select all
define command {
command_name check_wmi_plus
command_line $USER1$/check_wmi_plus.pl -H $HOSTADDRESS$ -u username -p password -t 15 $ARG1$
}
I would just try changing the -t 15 to -t 60 in your command def and see if that solves your problem.

I would think 15 seconds should be plenty.
I'm assuming this works form the Nagios server proper, just not from gearman? Is it on the same host or a different host? If different I'd look at your firewall configuration.

yes, with gearman the script's timeout is ignored.
yes, wiht gearman the script timeout is being ignored
We experience this issue on all services using check_wmi_plus.pl as plugin
No problem when running the check from the commandline of nagiosxi server and worker servers.
Our Modgearman workers and nagiosXI belong to the same subnet.

On the worker that is failing, can you increase the debug log level and send in the log file?
Edit the mod_gearman_worker.conf file on the remote worker.
Change this from
to
Restart the worker
Code: Select all
service mod_gearman_worker restart
Then post the following file after the check is run.
Code: Select all
/var/log/mod_gearman/mod_gearman_worker.log
