Hi guys

i'm new here, i use Nagios 4.0.2 and mod_gearman all works great.

Is anybody succeeded to run pnp4nagios with a gearman worker ?

Thank you

I have not tried with 4.0.2, but you can find information on the pnp4nagios website:
http://docs.pnp4nagios.org/pnp-0.6/modes#gearman_mode

Thank you I have already installed pnp4nagios 0.6 with Nagios 4.0.2 and mod_gearman but i have an error on web interface "perfdata is empty"

My pnp-worker works great there is no queue process. Under /usr/local/pnp4nagios/var/perfdata there is no file created

User nagios can write under /usr/local/pnp4nagios/var/perfdata and no error in logs.

i don't understand

Do you have logging enabled in process_perfdata.cfg? Have you added the necessary bulk processing commands to nagios.cfg?

Yes

Have you added the necessary bulk processing commands to nagios.cfg?

No i just followed this tutorial http://docs.pnp4nagios.org/pnp-0.6/config#gearman_mode, i thought with gearman this was not necessary

Hmm, I'm not sure how extensively mod_gearman has been tested with core 4 since the core workers were released with it. Can you send a copy of your nagios.cfg?

Hello happy new year!

the only thing i changed in nagios.cfg is :

Code: Select all

event_broker_options=-1
broker_module=/opt/lib/mod_gearman/mod_gearman.o config=/opt/etc/mod_gearman/mod_gearman_neb.conf
process_performance_data=1

and i just followed pnp4nagios + Gearman mode tutorial http://docs.pnp4nagios.org/pnp-0.6/modes#gearman_mode.

The perfdata is processing, here my gearman_top view

Code: Select all

Queue Name                       | Worker Available | Jobs Waiting | Jobs Running

 hostgroup_1                      |              15  |           0  |           1

 perfdata                         |               1  |           0  |           0
 worker_01                        |               1  |           0  |           0
 worker_02                        |               1  |           0  |           0
--------------------------------------------------------------------------

but the directory /usr/local/pnp4nagios/var/perfdata is still empty.
Nagios/pnp4nagios logs looks good

i can't figure out : /

EDIT:

I set up debug mode for pnp4nagios logs and here is the result :

My suspicion is that the "\n" in the perfdata is breaking processing. You may want to open up a bug report at: http://tracker.nagios.org
