Nagios Support Forum

Hello

On the monitored windows 2012 Servers

The plugin check_ntp_time.c'is placed Under C:\Program Files (x86)\Nagios\NCPA\plugins

Then when testing from NagiosXI to see if we can get the offset time from NTP
/usr/local/nagios/libexec/check_ncpa.py -H remotehost -t code-P 5693 -M 'plugins/check_ntp_time.c' -a "-u '-H NTPServerIP -w 60 -c 120'"

Resulting this

UNKNOWN: Error occurred while running the plugin. Use the verbose flag for more details.

Same result if executing
plugins/check_ntp_peer.c
or /check_time.c


Here is the listener log from the server hosting the NCPA agent

Any suggestion on how to acceive the same goal in different way that can work?

This plugin is not a Windows application, so it is not going to work... I would recommend finding a plugin that would work on Windows. Here's one that I found on the Nagios Exchange:

https://exchange.nagios.org/directory/P ... 29/details

Testing the plugin from the command line on the Nagios XI server: Hope this helps.

Thanks for sharing the right plugin

After placing the plugin on the target windows server
I am getting this when trying it on my end not sure what I am doing wrong. Can you idenify any wrong syntax?


[root@rdnagios libexec]# ./check_ncpa.py -H X.X.X.X -t Token -M 'plugins/check_windows_time.bat' -q 'args=1.1.1.1,args=60,args=120'
"C:\Program Files (x86)\Nagios\NCPA\plugins\check_windows_time.bat" - Nagios plugin that checks time offset against a specified ntp server.

Usage: "C:\Program Files (x86)\Nagios\NCPA\plugins\check_windows_time.bat" <timeserver> <warning threshold in seconds> <critical threshold in seconds>
Examples: "C:\Program Files (x86)\Nagios\NCPA\plugins\check_windows_time.bat" pool.ntp.org 120 300

Open the ncpa.cfg file in a text editor, change this line: to this: Save, exit, and restart ncpa_listener service on the Windows machine.

Next, try your check by adding "-v" at the end of your command for increased verbosity: and show the output.

Also, post the entire ncpa_listener.log on the forum. It should be located in the "C:\Program Files (x86)\Nagios\NCPA\var\log" folder.

The requested steps were done

Please find attached logs

Thanks for the logs! What is the output of the command below?

We haven't been able to recreate the issue in house. It seems like the plugin shows you the usage... it is almost like your arguments are not taken. I am not sure why this would be.

Have you modified the settings in the ncpa.cfg file from "defaults"? Can you post your ncpa.cfg file on the forum? Please hide/obfuscate sensitive info.

Have you tried running your check against a different NTP server? Can you try the command below and show the output?

Please find the attached ncpa.cfg of the target server

Do you get the same error when you run the command below?
