That's for NSCA. Does it also work for NRDP?
Right now Nagios tells me that "Service is not scheduled to be checked...".

Can you show us the passive checks that you have defined in the ncpa.cfg and post the "ncpa_passive.log"? That's my problem. I have no clue how to define a service for a passive check (sent via NRDP by a NCPA daemon). If I search for help about Nagios, NRDP and passive checks all I find i...

I'm a little confused now. You tell me that a pinging is the default behavior, yet the description says that "If you leave this argument blank, the host will not be actively checked." What exactly means "leave this argument blank"? Is this blank? (The directive "check_comman...

Okay, all active checks seem to work fine now.

I still have no clue where to start with NRDP and passive checks. I do not find any useful information on how to set it up.

So, whenever I define a host Nagios automatically monitors it via a PING check?

Okay, one question arose while setting up services:
How is the "host check" determined? From what I've understood so far an explicit "host check" is never performed, rather the "host check" is based on the results of the "service checks" on the same machine.

/sbin/iptables -I INPUT -p tcp -m tcp --dport 5693 -j ACCEPT /sbin/service iptables save This worked. But what exactly have I done here? The memory command worked as well. How can I set it up that the available memory is displayed in megabyte or gigabyte? "-n M" just puts an M behind ever...

Solved my issue with active checks with NCPA. If you ever encounter this "error of 13" error, the most likely cause seems to be wrongly set owner of rwx rights of a file; in my case it was the file check_ncpa.py . The user Nagios was not allowed to execute the file. The following command f...
