Jatin,

Here is how I use it with sudo :

In my nrpe.cfg :
command[check_mem]=/usr/bin/sudo
/usr/local/nagios-plugins/current/libexec/check_mem.pl -w 10 -c 5

visudo :
User_Alias      SU_TO_NAGIOS_PLUGINS_USER = nagios
Cmnd_Alias      SU_TO_NAGIOS_PLUGINS =
/usr/local/nagios-plugins/current/libexec/check_mem.pl -w 10 -c 5
SU_TO_NAGIOS_PLUGINS_USER ALL = NOPASSWD: SU_TO_NAGIOS_PLUGINS

Root permissions will allow nagios to read memory attributes.

Subject: [Nagios-users] check_mem shows : "NRPE: Unable to read output"

Hi

I had downloaded the perl file for check_mem plugin and copied in the 
libexec folder of the target machine that needs to be monitored. On the 
localhost it returns correct values but when i shoot the command from 
the nagios server using NRPE i am getting the following :

NRPE: Unable to read output

Is it an issue with NRPE or check_mem plugin.

The output for check_mem on the localhost is :

<b>CRITICAL: Memory Usage (W> 5, C> 6): 30% <br>Swap Usage (W> 5, C> 6):

1%</b>|MemUsed=30%;5;6 SwapUsed=1%;5;6

I have defined the command also in the nrpe.cfg file. All other commands

work fine except for the check_mem plugin.

Please let me know what to do next.

Thanks
Jatin
