Nagios Support Forum

on the ubuntu system:

root@gberger-ubuntu:/usr/local/nagios/libexec# /usr/local/nagios/libexec/check_cpu_stats.sh -w 85 -c 95
/usr/local/nagios/libexec/check_cpu_stats.sh: 140: /usr/local/nagios/libexec/check_cpu_stats.sh: Syntax error: redirection unexpected

on a RHEL6 system:
[root@ehealth-linux ~]# /usr/local/nagios/libexec/check_cpu_stats.sh -w 85 -c 95
CPU STATISTICS OK: user=2.61% system=10.02% iowait=0.00% idle=87.37% | user=2.61% system=10.02% iowait=0.0%;85;95 idle=87.37%

We can see there is an error.

What is the output of this command on your ubuntu system:

root@gberger-ubuntu:~# head /usr/local/nagios/libexec/check_cpu_stats.sh
#!/bin/sh
# ========================================================================================
# CPU Utilization Statistics plugin for Nagios
#
# Written by : Steve Bosek ([email protected])
# Release : 1.3
# Creation date : 8 September 2007
# Revision date : 18 October 2007
# Package : DTB Nagios Plugin
# Description : Nagios plugin (script) to check cpu utilization statistics.
root@gberger-ubuntu:~#

Change the first line from:
#!/bin/sh
To:
#!/bin/bash

Then try running the plugin from the command line again it should fix the problem.

Great, this seems to work now.

Question, shouldn't the ubuntu agent have this set be default, especially since we selected the ubuntu dist during the installation process?


We did not have an issue witth the RHEL6 and CentOS systems.

All right! I will be locking this topic.

I already let our developers know, and they are updating the plugin. The issue should be fixed shortly.
