Monitor Sangoma Vega VOIP Gateway with Nagios

Today the topic is about how we can monitor the Sangoma Vega VOIP Gateway with Nagios Core Monitoring tools. Around 6 months back I got a project to Build a Monitoring system for the entire IT infra. So I started with Nagios Core 4.3, and  it was going fine. Then I stuck in with Sangoma Vega 400G VOIP Gateway. Our Telephony server is connected with this Vega device and I want to monitor the Interface status, call status and No of active calls.

I started searching the same in Google and Forums, but no Luck. Finally I got the solution and configured the same. Here I mentioned all the steps I did to configure the same. Maybe this article will help you to set up Nagios monitoring for Sangoma Vega Device.

Therefore I use the below setup for Monitor Sangoma Vega with Nagios Core 

I use CentOS Linux 7.6

Nagios Configuration Directory:  /usr/local/Nagios/etc/objects

First of all, you have to configure the Vega device so follow the below steps

Step-1

  1. Login to the Vega web application
  2. Go to Expert Config
  3. Under Expert Config select LoggingNagious monitoring
  4. Create the SNMP Communities and enable Get, Set and Traps
  5. Add your SNMP server IP and subnet in SNMP Manager 
  6. Select the Community and the SNMP versions 

Now we have to Add the Host in the Nagios 

Now you have to add the Vega MIB file in Nagios Core.

Step-2

First of all you have to Define the Host. So I add the host details in the /usr/local/nagios/etc/objects/switch.cfg. Below is the host entry. You can also create a separate host file for that. 

define host{

    Use generic-switch; Inherit default values from a template

    host_name vegagateway; The name we’re giving to this Gateway

    alias   Sangoma Vega Gateway; A longer name associated with the Gateway

    address   192.168.1.1; IP address of the Gateway

    hostgroups  witches; Host groups this Gateway is associated with

    }

After that you have to create a service Template. There for I add the below template in /usr/local/nagios/etc/objects/templates.cfg

define service{

name telephonyservice ; The ‘name’ of this service template

active_checks_enabled 1; Active service checks are enabled

passive_checks_enabled 1; Passive service checks are enabled/accepted

parallelize_check 1; Active service checks should be parallelized

obsess_over_service 1; We should obsess over this service (if necessary)

check_freshness 0; Default is to NOT check service ‘freshness’

notifications_enabled 1; Service notifications are enabled

event_handler_enabled 1; Service event handler is enabled

flap_detection_enabled 1; Flap detection is enabled

process_perf_data 1 ; Process performance data

retain_status_information   ; Retain status information across program restarts

retain_nonstatus_information ; Retain non-status information across program restarts

is_volatile 0; The service is not volatile

check_period 24×7; The service can be checked at any time of the day

max_check_attempts 3; Re-check the service up to 3 times 

check_interval 5; Check the service every 10 minutes

retry_interval 2; Re-check the service every two minutes

contact_groups admins; Notifications get sent out to everyone in the ‘admins’ group

notification_options   w,u,c,r; Send notifications about warning, unknown, critical, and recovery notification_interval       10; Re-notify about service problems every hour

notification_period      24×7; Notifications can be sent out at any time

    register 0; DON’T REGISTER THIS DEFINITION – IT’S NOT A REAL SERVICE

}

Step-3

After that You have to do the below services entry /usr/local/nagios/etc/objects/switch.cfg under SERVICE DEFINITIONS section

The below service monitor the ISDN port. The Sangoma Vega 400G have 2 LAN port and 4 PRI port

So the port range is ifOperStatus.1 – ifOperStatus.6 First 2 port is for LAN and 3-6 are for PRI

So in the below Service definition it will monitor the First PRI port

define service{

    use   telephonyservice; Inherit values from a template

    host_name vegagateway; The name of the host the service

    service_description ISDN-Port1; The service description

     check_command   check_snmp!-C public -o ifOperStatus.3 -r 1 -m RFC1213-MIB; The command used to monitor the service

     check_interval    5; Check the service every 5 minutes under normal conditions

     retry_interval    1; Re-check the service every minute until its final/hard state is determined

    }

The below service monitors the concurrent calls on that particular port. Here I also use  the same port similarly ifOutboundCurrUse.3 mean the first PRI port 

define service{

    use telephonyservice; Inherit values from a template

    host_name vegagateway; The name of the host the service

    service_description Calls-Port1; The service description

    check_command   check_snmp!-C public -o ifOutboundCurrUse.3 -r 1 -m Vega-MIB -w 28 -c 29; The command used to monitor the service

    check_interval 5; Check the service every 5 minutes under normal conditions

    retry_interval 1; Re-check the service every minute until its final/hard state is determined

    }

Vega current calls
