hi,

Could you please tell me why i have those wrong messages on my nagios interface ?

thanx

You mean on the Windows server? The answer is in the error:

NSClient - Error: Invalid Password.

When you set up your check_nt command, you need to include an option for the password (secret), if you don't use a seperate line for each host, you'll need to make sure when installing NSClient++ to use the same password on all servers:

Code:

# 'check_nt' command definition

define command{

        command_name    check_nt

        command_line    $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -s <password set up on NSClient> -v $ARG1$ $ARG2$

        }

Or the nrpe ones? Those are because either your nagios plugins on the client, or the nrpe plugin on the server isn't installed to use ssl, and the other is. Either both need to be configured with ssl, or both need to be configured without.

Your timing of posting this is actually funny to me. Monday I had to learn how to get Nagios up and running as we're looking at possibly using that to monitor our servers. So I've been troubleshooting issues like this non-stop the last 3 days and have learned ever so much about nagios and the configuration. Still haven't figured out how to get check_nt to check disk i/o though. Got it working on linux through check_iostst, but total failure so far in Windows.

Thanks for your answer.
i am from Paris and beginner on linux system.
can you help me with nagios issues ?
can you tell me what i can monitoring with nagios ?
cpu, free disk space, ram etc... but what about the others services ?

The ldap and DNS don't know. Like I said, I started working with nagios Monday, so have 4 days of experience. This is also not in the scope that my company wants to monitor with nagios, so can't really be of any use there.

Hopefully there's someone with more experience that can help you more than I can.

You can monitor almost anything; start here https://library.nagios.com/library/products/nagioscore and get an acct at the community forums
