Nagios Support Forum

So I am monitoring the service, confirmed by running tasklist on the box. I'm running NSClient version 0.4.0.172. Even the local nagios http service is reporting incorrect, and that's the config "out of the box" I didn't touch that at all. Also, as for the email, I already have my exchange...

Also, anyone else have the incorrect reporting with check_nt. I will try to figure out the npre - but I am not clear on that yet. Is it a remote sid...

Nagios is working, I am able to add hosts and such, they appear on the web GUI, etc. My issue is two things: 1...

Thank you so much!! I really appreciate it. That was the issue, I'm on my way now, thank you. yum install perl was the answer.

I installed all packages as per the quickstart guide. Using yum to install them. What can I do to check if Perl is installed and if not, how to install?

more information, when running the ./configure --with-command-group=nagcmd I get the attached as part of the output
