NCPA and NRDS - ERROR... File contains no section headers.

Hello,

I can't seem to get nrds working on the ncpa client. Please see below:

What OS and version is NCPA installed on?

[tkersten]

Hello,

It's SLES 12. I hope that helps.

Thank you.

[tgriep]

On the Nagios XI server in this folder

Code: Select all

/usr/local/nrdp/configs/

is a config file setup for your SLES server.
Can you post that file here?

I think I mentioned this on the forum before - the NCPA-NRDS integration was not fully implemented. The [NRDS] section ended up in the ncpa.cfg by mistake. There should be another ("NCPA") section under the "NRDS Config Manager", but this is still a "work in progress". The idea was to manage all of the nrds or ncpa configs from one, central location (the "NRDS Config Manager" in Nagios XI). This way, you won't need to log in to each client and make any changes there.

It looks like you already installed the NRDS client - these are the "default" Linux checks:

command[__HOST__]=/usr/local/nagios/libexec/check_ping -H localhost -w 200.0,40% -c 400.0,80% -p 1
command[Check Users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
command[Check Load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
command[Check Disk]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /
command[Check Zombie Procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
command[Check Total Procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200

These checks are run on the cron job and could be modified from within the "NRDS Config Manager". I would change:

Code: Select all

handlers = nrds

to

Code: Select all

handlers = nrdp

in the ncpa.cfg.

Note: You can still use NCPA with passive checks but you won't be able to modify them (make changes) from one, central location. You will need to log into each client, modify the checks under the "[passive checks]" section, and restart the "ncpa_passive" service. I hope this makes sense.

Hello,

Ahh, I understand what you mean and the future plans of having everything in XI sounds great. OK, I guess I'll keep an eye out to see if this changes in the future then. In the meantime, can I suggest changing documentation or otherwise to avoid others spending the time I spent on this before reaching this point?

Thank you.

I will be locking this topic for the time being. If the issue is not fixed in the next version of NCPA, feel free to start a new thread. Meanwhile, I am going to follow on this with our developers. Thank you!
