Nagios Support Forum

Hi Team,

We have a HP-UX box for which CPU statistics is not showing data when we are running the script as a service.

However when we are running it manually on server it's working fine.
Server output:
/opt/nrpe/libexec/check_cpu.sh
CPU STATISTICS OK : user=0% system=0% iowait=0% idle=100% nice=0.00% steal=0.00% | CpuUser=0;CpuSystem=0;CpuIowait=0;CpuIdle=100;CpuNice=00.0;CpuSteal=00.0;70,40,30;90,60,40
Nagios error:
/usr/local/nagios/libexec/check_nrpe -H 172.24.x.x-t 60 -c check_cpu -n -a '-w 70,40,30 -c 90,40,30'
ERROR : Bad count parameter in Warning Threshold

# Release : 2.3
# Creation date : 8 September 2007

# Package : DTB Nagios Plugin
# Description : Nagios plugin (script) to check cpu utilization statistics.
# This script has been designed and written on Unix plateform (Lin

easily
# be changed by editing the variables $IOSTAT at the top of the sc
ript.
# The script is used to query 6 of the key cpu statistics (user,sy
stem,iowait,steal,nice,idle)
# at the same time.

# USAGE : ./check_cpu_stats.sh Regards,

We don't support custom plugins but here are some troubleshooting steps.

Run the plugin as the nrpe user, usually this is the user nagios. You can find it's definition in nrpe.cfg.
Run the plugin locally through nrpe, eg check_nrpe -H 127.0.0.1
Use the latest NRPE daemon and run in debug mode:

Just checking in since we have not heard from you in a while. Did @avandemore's post clear things up or has the issue otherwise been resolved?

Hi ,

I believe this is nagios plugin. Also the plugin is working locally not working when we are configuring as a service.

However it's suddenly start throwing the error.

The error
ERROR : Bad count parameter in Warning Threshold
It is caused by too many variables in the warning and critical threshold settings when you ran the check using the check_nrpe plugin.

Try this example below and see it it works for you.

We are getting same error. Please find below the data:

[root@dfwlxngxi01 ~]# /usr/local/nagios/libexec/check_nrpe -H snguxap7.X.X. -t 60 -c check_cpu -n -a '-w 70 -c 90'

Can you post the nrpe.cfg file from the HP-UX server so we can see view the settings?

I have restarted the NRPE Agent and it's started working fine.

Did you have any further (related) questions or are we okay to close this thread?

Yes..U can close the thread.
