Some questions about NCPA

[tgriep]

Try running this for the firewall settings to see if that allows all hosts in.

Code: Select all

/sbin/iptables -I INPUT -p tcp -m tcp --dport 5693 -j ACCEPT
/sbin/service iptables save

For your check, you would only have to define it like this.

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H 192.168.56.1 -t nagi_os_NCPA -P 5693 -M memory/virtual

Try that and see if that resolves it for you.

/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 everything instead of the default value (it even replaces the "%").

How do I translate this to an command:

Code: Select all

https://192.168.56.1:5693/api/disk/logical/C:|?token=nagi_os_NCPA

This freezes the terminal, I have to cancel it with CTRL + C:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H 192.168.56.1 -t nagi_os_NCPA -P 5693 -M disk/logical/C:|

Try wrapping the "disk/logical/C:|" in single quotes:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H 192.168.56.1 -t nagi_os_NCPA -P 5693 -M 'disk/logical/C:|'

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.

What is the specific issue that you are having at the moment? 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 is the installation guide and threads of people who attempted to use NRDP but eventually given up because they could not figure out how to get it running.

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

[Box293]

In relation to passive checks the service definitions remain the same.

If your Nagios services are not being updated from the NRDP client, check the nagios.log file as it will make noise if it can't find the host or service.
