Objective
- Prerequisites: It is assumed that the participants know how to administer and operate PRTG Network Monitor or have previously participated in the course PEUP01 – The Core of PRTG.
- Duration: 8 hours.
- Description:
Asterisk is a software implementation that powers IP PBX systems, VoIP gateways, conference servers, and is used by SMBs, call centers, carriers, governments and all kind of companies worldwide, therefore it’s an important component to monitor. IT admins needs to continuously control the amount of concurrent calls processed at peak levels, down service events, resource availability of the Asterisk server and so on.
We have designed this training so that Asterisk administrators can learn how to create a monitoring scheme using PRTG Network Monitor automating the surveillance of Asterisk as a whole and get the most out of this excellent monitoring tool.
Students will learn how to monitor Asterisk servers using the SSH and SNMP telemetry protocols, which offer different forms of complementary control. Using SSH we will teach how to quickly create PRTG plug and play sensors and how to create customizable sensors using an SSH script to monitor the hardware and operating system where Asterisk resides.
The SNMP protocol allows direct monitoring of the Asterisk application, for this purpose we will show how to enable and validate the operation of the telemetric service in Asterisk and in the Operating System and also how to use the MIB file to create customizable sensors.

Custom Sensors
Custom sensors can perform a number of monitoring tasks that extend the standard sensor set. Apart from parameterized versions of Simple Network Management Protocol (SNMP), Packet Sniffer, and NetFlow sensors, you can create your own sensors using Windows Management Instrumentation Query Language (WQL) or Python, by compiling an .exe file, using any Windows software development tool, and you can request any Representational State Transfer (REST) application programming interface (API) that returns JavaScript Object Notation (JSON) or Extensible Markup Language (XML) and map the results to channels.
We will be showing how to use the following sensors:
Asterisk Sensors
The training will be focused on how to create a monitoring schema to check the Asterisk Services like the Active/processed Calls.
In the training
- How SNMP works
- The Asterisk Mib File
- https://www.circitor.fr/Mibs/Html/A/ASTERISK-MIB.php
- How to import/test the MIB File in PRTG
- How to create a custom sensors for Asterisk using the SNMP OID’s
Notes:
1) The SNMP configuration for the Asterisk is out of the scope of this training.
We can recommend the following link for that purpose:

2) Beware that we aren’t an Asterisk expert so we will be using for the training some basic OID’s.
