I've been trying to install this pluggin on my nagios but i'm not able to make it works. I'm monitoring an asterisk server from my Nagios server and now i want to add this pluggin to monitorize a trunk SIP state. My goal is to set up an alert for this to be informed in case the SIP trunk is down. We have better deal with this provider so in case that the SIP trunk is down we can adjust our calling policy til the SIP trunk recovers and start using it again.
I think i finally install the pluggin but is not working as expected. I'm gonna write down all the process that i followed and if you can take a look and tell me where i'm wrong and how to fix it i'll grateful.
- First of all I add the pluggin .sh into my nagios pluggin folder.
- Then I went to commands.cfg and add the following command.
Code: Select all
define command{
command_name check_peer_status
command_line /usr/lib64/nagios/plugins/check_peer_status.sh -H 192.168.253.60 -u root - s PASSWORD -t sip -p T-partner
}- After that I went to my file newhost.cfg where I have defined my monitorized hosts and the services and add this.
Code: Select all
define service {
use generic-service
host_name asterisk_voip
service_description Custom SIP monitor
check_command check_peer_status
}- I restart the service and everything seems to work fine, but when I go to the Nagios web interface I find this warning for the service.
Code: Select all

Check your configuration file(s) to ensure that they contain valid
directives and data defintions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read

'Whats New' section to find out what has changed.[/color]
I get the pluggin on http://exchange.nagios.org/directory/Pl ... us/details and this is the script if you want to check it
