how to monitor a process that shouldn't be running ?

[nagmoto]

Hi

check_proc doesn't alert if a process shouldn't running.
Is there other plugin can do this kind of checking ?
Ex, a host has telnet or ftp server daemon running should trigger an alert.


Thanks

You could actually do this, just set your critical value to >=1 like so:

Code: Select all

/path/to/your/check_procs -c 1 -C nagios

Return: PROCS CRITICAL: 6 processes with command name 'nagios' | procs=6;20;1;0;

There are some fancier things you can do, to get the full usage, check out:

Code: Select all

/path/to/your/check_procs -h

Thanks for the answer on checking the ftp or sshd process using check_proc command.

Can I also do the ftp/ssh port scanning from Nagios server side ?

In regards to your first question that slansing answered, you can also use the negate plugin in similar situations where the threshold might not be a viable option:

The doc mentions XI but works for Core as well.

As for the port scanning, that is available in XI using the Autodiscover Wizard, which uses nmap in the backend.
