I am using nsclient on a windows server and trying to get the status of a process on the server using check_nt. I want check_nt to return CRITICAL when the process is not running on the server instead it is returning Warning. Is there something that I have to specify in the command line to report it as CRITICAL. This is the command that I am using
What version of NSClient are you using? I know in some cases upgrading to NSCP-0.4.1.90-x64 has fixed similar issues. That said, There are some pretty serious bugs in 4.3, so I would suggest 4.4 or higher. Of course, if you are already using a newer version, we will have to dig a little deeper.
on both the server and the client run nmap on that port and give the output. Do that locally if you are not your network admin (else you might get a call from your network admin).
Once we know where it's closed, we can work on opening it up.
