ncpa passive checks not working

We have the 1.1 ncpa client and Nagios XI 2014R1.1 server version. I was trying to find a newer linux/windows client but the ncpa download site doesn't really tell you what version it is?

Anyway, I am doing this passive check with that agent and on the nagios server side it just says: "no check results for service yet..."

I have added the passive check on the server side via the wizard.

Here is the client ncpa.cfg:

Code: Select all

[listener]
uid = root
certificate = adhoc
loglevel = debug
ip = 0.0.0.0
gid = root
port = 5693
logfile = var/ncpa_posix_listener.log
pidfile = var/ncpa_posix_listener.pid

[passive]
uid = nagios
handlers = nrdp
loglevel = debug
gid = nagcmd
sleep = 5
logfile = var/ncpa_posix_passive.log
pidfile = var/ncpa_posix_passive.pid

[nrdp]
token = thetoken
hostname = hostname.domain.com
parent = http://hostname.domain.com/nrdp/

[api]
community_string = thecommunitystring

[plugin directives]
plugin_path = plugins/
.sh = /bin/sh $plugin_name $plugin_args
.ps1 = powershell -ExecutionPolicy Unrestricted $plugin_name $plugin_args
.vbs = cscript $plugin_name $plugin_args //NoLogo

[passive checks]
hostname.domain.com|cpu usage = /cpu/percent --warning 80 --critical 90
hostname.domain.com|swap usage = /memory/swap/percent --warning 80 --critical 90
hostname.domain.com|memory usage = /memory/virtual/percent --warning 80 --critical 90
hostname.domain.com|disk-root-used-percent = /disk/logical/|/used_percent --warning 80 --critical 90

The last one is specifically what I added but isn't working.


Any ideas ?

Thanks!

Go to Configure -> Unconfigured Objects. Is anything listed there?

There are quite a few in there but doesn't seem like the one I am looking for. If I clear those out for now will those come back ?

Also, here is what I see on the cilent side in the passive log file... for the one check:

I see this in the host event log though. But if this is the check coming back why wouldn't the hostname be in there ?

Code: Select all

2014-06-10 15:44:46   Error: Got host check result for '', but no such host can be found

[passive checks]
hostname.domain.com|cpu usage = /cpu/percent --warning 80 --critical 90
hostname.domain.com|swap usage = /memory/swap/percent --warning 80 --critical 90
hostname.domain.com|memory usage = /memory/virtual/percent --warning 80 --critical 90
hostname.domain.com|disk-root-used-percent = /disk/logical/|/used_percent --warning 80 --critical 90
Try replacing the "hostname.domain.com" with "%HOSTNAME%", for example:

Code: Select all

%HOSTNAME%|cpu usage = /cpu/percent --warning 80 --critical 90
Save ncpa.cfg and exit. Restart both NCPA services (Listener & Passive).

If this is not fixing your issue, post the "ncpa_passive.log".

I have tried that but that also doesn't seem to work. Here is the output. I did change what the real host name is to: hostname.domain.com in the following.

Thanks

Hm-m, you have "4 checks processed" in the log... Do you have anything in the Unconfigured Objects? Do other (not ncpa) passive checks work fine?

Go to: Admin->Performance Settings->Subsystem, and show us a screenshot of this page.

Yes nothing in un-configured objects listed. It seems like other passive checks are working? Just not the disk-root-used-percent on specifically. seeing the "OK: No data received yet." on that one. I know the "disk root used percent" shows as critical .. I did remove that check but not sure why that one is still showing up.

You don't have anything in Unconfigured Object as these checks are already configured. They seem to be working fine now, after the modifications you made with the exception of the disk check.

Do you see the correct value in the API?

Code: Select all

https://<ip address>:5693/api/disk/logical/|/used_percent
You need to see something like this:

Code: Select all

{
  "value": {
    "used_percent": [
      55.9, 
      "%"
    ]
  }
}
