Nagios Support Forum

I still haven't figured this one out. Doesn't it seem very odd that these UNKNOWN entities can be queried just fine via the host NCPA API and via cli from the nagios host but show up as unknown in the Web UI? This is from the nagios log.. note checking / works fine but the other two mount points don...

Greetings, Strange issue where some valid services and mounts show up as UNKNOWN in the 4.4.6 core web UI but direct queries provide valid return data. api shows valid data as well. Direct query of a mount point: /usr/local/nagios/libexec/./check_ncpa.py -H host -t 'token' -P 5693 -M 'disk/logical/|...

This was an iptables issue needing to add ACCEPT rules before REJECT rules on the client.

Greetings, Running a Nagios 4.4.6 core server and using NCPA active checks on a group of hosts. All Windows hosts and a RHEL 8 server working fine. Got a Redhat 6 server with the NCPA 2.2.2 linux 64bit client installed and listener is up. Firewall opened for default tcp 5693 on the client. Set token...

I think I figured it out.. maybe this will help the next newb.. replace / with | [nagios@server etc]$ /usr/local/nagios/libexec/check_ncpa.py -H client -t 'token' -P 5693 -M 'disk/logical/|/free' --warning 10: --critical 5: -u G OK: Free was 50.23 GB | 'free'=50.23GB;10:;5:; [nagios@server etc]$ /us...

Thanks all the examples are for Windows disks. All I need is an example of the syntax for checking /var/log which I can't seem to find anywhere.

Hello all, I've stood up a 4.4.6 core install and using NCPA client on Windows and Linux clients. I've managed to get the Windows clients reporting properly for services etc. I can't find any examples of config files for Linux specifically syntax for checking partitions/mount points. I'd like to mon...

Oh my what a newb mistake. Normally we don't have windows firewall on but did on a test client. Things work fine now with the NCPA config.

Thanks Ben,

Perhaps I'm confused as I don't see any tokens being passed in the configs on the referenced object def site. How does Nagios authenticate to the NCPA client?

Thanks again for your reply.

Greetings, I'm just looking for some clarity on what is the proper config for active monitoring of Windows. I had it in my brain that NCPA was sort of a replacement for the NSClient. I'm working with the latest 4.4.6 core code in a new install. The sample config files for Windows have the NSClient r...
