RedHat NCPA test install - UNKNOWN for all checks

Hello XI Support

We have installed NCPA agent on the test RedHat EL 6.6
All checks produced same error: UNKNOWN: Error occurred while running the plugin. Use the verbose flag for more details.

Please advice how to troubleshoot from here?

Thank you

What version of the NCPA agent did you install? Run the following commands on the RHEL machine, and show the output in code wraps:

Code: Select all

ps -ef | grep ncpa
tail -100 /usr/local/ncpa/var/ncpa_listener.log
Show us one of the "failing" checks run from the command line on the Nagios XI server along with the output of it.

Example:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H <client ip> -t 'mytoken' -P 5693 -M memory/virtual/percent -w 80 -c 90

In this case, the issue may be in the wizard. What is the version of the "NCPA Agent" wizard that you are currently using?

Admin->Manage Config Wizards

Can you show us the "memory usage" service configuration?

CCM->Services->memory usage->View Text Config

-t 'ncpa_test' -P 5693 -M memory/virtual/percent -w 50 -c 80
Can you show us the actual config file? I expected to see something like this:

Code: Select all

define service {
	host_name				x.x.x.x
	service_description		Main Memory Usage
	use						xiwizard_ncpa_service
	check_command			check_xi_ncpa_agent!-t 'mytoken' -P 5693 -M memory/virtual/percent -w 50 -c 80
	max_check_attempts		5
	check_interval			5
	retry_interval			1
	check_period			xi_timeperiod_24x7
	notification_interval	60
	notification_period		xi_timeperiod_24x7
	contacts				nagiosadmin
	_xiwizard				ncpa
	register				1
	}
Also, show us the screenshot of the "Service Status" page with the failing ("Unknown") services.

We saw that your check works from the command line when using an IP address:
Works from XI CLI:
[root@fikc-nagxidev01 ~]# /usr/local/nagios/libexec/check_ncpa.py -H 10.102.36.62 -t 'ncpa_test' -P 5693 -M memory/virtual/percent -w 80 -c 90
OK: percent was 35% | 'percent_0'=35%;80;90;
Does it work with a hostname? What is the output of the following commands?

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H fihp-rheltst01.konecranes.com -t 'ncpa_test' -P 5693 -M memory/virtual/percent -w 80 -c 90
nslookup fihp-rheltst01.konecranes.com

nslookup fihp-rheltst01.konecranes.com

This worked too ("localhost" somehow appeared under host address after using NCPA agent Wizard. Unsure if this specific to us.
- sorry did not check (did not think about something that simple)

Got it - guessing this is similar to the last one you mentioned with the wizard.

Are we good to mark this thread as resolved?
