Hi [email protected],

Can you run the full check command from the CLI on the Nagios XI server so we can take look at the plugin you are using any arguments being passed? Please post the full output to the thread as well.

The,

The system module in NCPA is for getting basic information and does not have the ability to perform many checks.

{
"system": {
"node": "localhost.localdomain",
"machine": "x86_64",
"uptime": [
1456124,
"s"
],
"version": "#1 SMP Fri Apr 20 16:44:24 UTC 2018",
"time": 1613148917.61594,
"release": "3.10.0-862.el7.x86_64",
"timezone": [
"CST",
"CDT"
],
"agent_version": "2.2.2",
"system": "Linux",
"processor": "x86_64"
}
}

See: https://www.nagios.org/ncpa/help.php#api-modules-system

If you want to check the offset of the system time against a NTP server, I would recommend using check_ntp_time (part of the nagios plugins).

See: https://www.monitoring-plugins.org/doc/ ... _time.html

You'll have to install on the NCPA server and put in the the plugins directory. An example, check would be as follows:

Code: Select all

./check_ncpa.py -H <ip-address-remote-host> -t '<your token>' -M 'plugins/check_ntp_time' -q 'args= -H 0.centos.pool.ntp.org  -w 0.5 -c 1'

Let us know if you need assistance installing the plugin or setting this up.
