nagios wont monitor the service groups i have defined

Post by sampan1 »

I configured the server file to add a host however after adding the configs I tried to monitor the groups I defined on the web console but it didn't show.
I ran the 'systemctl status nagios -l' command. Below is the output

Code: Select all


 systemctl status nagios -l

Hi @ampan1

Did you restart Nagios after after adding the host/services to your configuration?

Code: Select all

service nagios stop
service nagios start
You may have an error in your notification command. Are you receiving notifications? Try running the following to check for configuration errors:

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

There are few options for monitoring agents. You can use NRPE to monitor Linux and NSClient++ to monitor Windows systems.

However, we also have our own cross platform monitoring agent called NCPA (Nagios Cross Platform Monitoring Agent) that you can use for both Linux and Windows.

NCPA Downloads:
https://www.nagios.org/ncpa/#downloads
NCPA Documentation:
https://www.nagios.org/ncpa/#docs

To get started with NRPE on Linux, see:

Monitoring Hosts with NRPE:

Let me know if you have any other questions.
