Hi Team,

I had successfully installed centreon NSClient on windows server 2019 and modified the parameter in 

nsclient.in file and add my poller servers IP address like 172.24.XX.XX/32. 

restarted the nscp service. 

what is the next step ? unable to view the systems in Centreon Server’s host for monitoring.

Please help.  Thanks.

Hi there,

First thing first, did you add the centreon server in allowed host parameter on nsclient.ini ?

Then test communication between centreon and your client with telnet.

telnet <client IP> <port>

If telnet is working on port you defined, test communication from centreon with your plugin

check_nt -H <client IP> -p 12489 -v CLIENTVERSION

Hi  Jul3s,

i am able to telnet from Centeron poller to client ip with port 5666

Below command is correct to test the connectivity from Centeron poller to below client ip

 check_nt -H 172.24.xx.xx -p 12489 -v Centreon NSClient++

Please try those commands from centreon server :

check_nt -H <client ip> -p 12489 -v USEDDISKSPACE  -l C -w 80 -c 90

check_nt -H <client ip> -p 12489 -v CPULOAD  -l 2,95,100

 

If both are working, that means you can, at least, monitor space and cpu.

 

Next step, will be to create the client host and the services if not already created on your centreon WUI

-bash: check_nt: command not found
 

You got to put the complete path to check_nt if not defined in your PATH env variable.

Exemple : /usr/lib64/nagios/plugins/check_nt -H 172.24.xx.xx -p 12489 -v USEDDISKSPACE  -l C -w 80 -c 90

Hi Jul3s,

 

Thanks for the update. issue resolved now.

For notification I had configured Postfix on Centreon server and tested the smpt and able to receive email from Centreon by using SMTP commands. Still notification is not receiving for critical event generated Centreon WUI.
