Nagios Core 4.0 with NCPA and NRDP

[abrist]

Can post the newest ncpa log entries?

[skynardo]

Sorry for the delay, got side tracked on a couple other projects. Below are the current ncpa_passive.log entries:
I am no longer getting the /tmp files piling up on my nagios server.

Did you define a host a host for NCPA's NRDS to send to? Is that a valid configuration in NRDP on the nagios server?

[skynardo]

Are you talking about the host definition for the machine where the NCPA client is running? If so, this is that definition:

define host{
use linux-server
host_name devut514
alias devut514
address devut514.unigroupinc.com
}

Or do you mean I need to define my nagios Host as well ?

Here is the current service status

[sreinhardt]

He means on the NCPA server, did you specify the configuration options for the NRDP receiver (generally on the nagios machine)? Since NRDP is passive, the agent needs to know where to send data back to.

[yancy]

skynardo,

Can you run the following on your Nagios Core box

Code: Select all

cat corelog.newobjects

Thanks,

-Yancy

[skynardo]

OK, ncpa is sending the 3 checks to my nagios server (where nrdp server is installed)
nagios.log is complaining about the host being ""

[1382730952] Successfully launched command file worker with pid 3615

My ncpa.cfg on devut514 is shown below:
Note, I changed %HOSTNAME% to devut514 in the [passive checks] stanza, but still having the same issue

Yancy,

I did a find from root on my nagios server and could not find a file named corelog.newobjects

[slansing]

You still have not told us if you created the configuration for "devut514" on the nagios server. It would be created in:

Code: Select all

http://<ipaddress.of.nagios.server>/nrdp

Does "Freddy" exist?

In one of your original posts you indicated a passive check result coming from "devhost":

### NRDP Check ###
start_time=1382019953.0
# Time: Thu, 17 Oct 2013 09:25:53 -0500
host_name=
devhost

check_type=1
early_timeout=1
exited_ok=1
return_code=1
output=
WARNING: Percent was 11.8%|'percent_0'=11.8%;9;80

If this is the case "Freddy" may have the wrong configuration.

[skynardo]

I apologize, when you asked about creating a configuration for devut514 on the nagios server, I thought you were referring to the nagios host definition under /usr/loca/nagios/etc. For NRDP, I only followed the INSTALL.TXT file found in /usr/local/nrdp which does not mention creating configurations for clients that are sending passive checks to NRDP server (which is what I think you are saying I need to do). Freddy==devhost==devut514. I was initially trying to strip out actual host names, but in later posts failed to do so.

[slansing]

No problem at all this can get a bit confusing at times..

So, you do have Freddy listed as the host on the nagios server?

Freddy==devhost==devut514

Because NCPA's NRDS must send to a valid and current host configuration.
