Nagios: bash is missing

Question

I'm monitoring NTP server with nagios and nrpe, at the nagios server, when I get the following error: Service Status UNKNOWN Status information I am missing an important component : bash

The plugin is: http://archive.groundworkopensource.com/groundwork-opensource/trunk/monitor-core/nagios/plugins-contrib/check_procr.sh

The output when I do bash -x check_procr.sh is:

+ myself=check_procr + verify_dep + needed='bash cut egrep expr grep let ps sed sort tail test tr wc' ++ echo bash cut egrep expr grep let ps sed sort tail test tr wc + for i in '`echo $needed`' + type bash /dev/null + '[' 1 -eq 1 ']' + echo 'I am missing an important component : bash' I am missing an important component : bash + echo 'Cannot continue, sorry, try to find the missing one...' Cannot continue, sorry, try to find the missing one... + exit 3 

Thanks in advance

Answer 1

Edit the function verify_dep() so that the line

 type $i > /dev/null 2>&1 /dev/null 

is changed to

 type $i > /dev/null 2>&1 

Afterwards, it should work. The original line was wrong and always resulted in an error.
