Nagios Support Forum

Hi!
I use check_procs plugin to check processes running on remote hosts via NRPE.
Everything is OK, but only for the one of remote hosts I get wrong response on web-interface.
It constantly shows from 15 till 30 Zombies on host. When I check with top locally, there are no Zombies or maximum 1.
I tried to run the plugin locally and compared with top output. They both give identical response.
That means it is not the plugin problem.
Any ideas what should I check ?
Thank you

What do you have defined as the NRPE command for this plugin on the machine that is misbehaving?

nrpe.cfg

command[check_zombie_procs]=/usr/lib64/nagios/plugins/check_procs -w 20 -c 30 -s Z

Can you post both the output from running the command manually on the remote host and the result of the NRPE from the XI interface?

In addition, in the XI interface for that service can you click the service name and under the Advanced tab post a screenshot so I can see the perfdata?

Sorry, but I'm using Nagios Core

for now I have again Zombies = 0 on web interface.
As soon as I get this issue again, I will send you output of web -interface, plugin's output and top output

My mistake. Same process though. This is the info I need:

it is on web-interface :

this is a CLI command I run locally:
./check_procs -w 20 -c 30 -s Z


the output:
PROCS OK: 0 processes with STATE = Z

Zombies numbers are different on web-interface and taken from service windows because this number is changing constantly. From 0 till 30.
Do you need real image of window?

I've just remarked that PERFORMANCE DATA line is empty for all services for all hosts.
Something is wrong with that?

Performance Data: rta=0.044000ms;300.000000;500.000000;0.000000 pl=0%;80;100;0
that is for the host the service is running on
