Nsclient++ Check_Mem

[tenda21]

Anyone know how to change the ok, the status information and put something like: Memory usage: total: 3838.52 Mb - used: 1178.90 Mb (31%) - free: 2659.61 Mb (69%)

That change would have to be made to the plugin that is running the check, as that is what is responsible for this status output.

[tenda21]

know where is this plugin to make the necessary changes?

The plugin is likely check_nt. This is a compiled c program, so you will need to find the source code from our nagios-plugins github account or write a wrapper script to call instead and alter it.

I'm using the alias of NSClient + +, would not use the nrpe make make the query to a windows server:

My configuracion:

define service{
use generic-service
host_name teste
service_description Memory
check_command check_nrpe!alias_mem
}

But a teste:

In commands.cfg

define command {
command_name check_mem
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -n -c CheckMem -a type=physical MaxWarn=$ARG1$ MaxCrit=$ARG2$ ShowAll=long
}

In test.cfg
define service{
use generic-service
host_name test
service_description RAMss
check_command check_mem
}

But nagios display: CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

OK, so you are using check_nrpe, it is still a compiled c program and the source would need to be modified or a wrapper script created to call it and then alter the output. If you wish to look at the source, it is on our sourceforge account for nrpe(included with the linux daemon)

[tenda21]

to be able to use the command check_mem have to create a script?

[sreinhardt]

No, likely you just need to enable it on your nsclient system. Could you post your nsc.ini please? Also run:

Code: Select all

nmap -p 5666 [host\IP of nsclient system]

Is that the only nsclient/nsc.ini file in your installation directory? That looks like a sample.
