Monitor Netphone calls with Checkmk
The modular monitoring tool Checkmk gives you an overview of your Netphone servers.
With the network monitoring tool Checkmk you can record the number of simultaneously active calls of a Swyx or Netphone server. We have compiled the necessary settings for you below.
Step 1
The Checkmk Agent must be installed on the Swyxserver. In the file C:\ProgramData\checkmk\agent\check_mk.user.yml enter the following sequence in the section winperf:
winperf:
counters:
- SwyxServer: swyxserver
This means that the performance values of Swyx are also output by the Checkmk Agent.
Step 2:
Create the file winperf_swyxserver with this content on the Checkmk server under /opt/omd/sites/<sitename>/local/share/check_mk/checks:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
# Example output from agent:
# <<<winperf_swyxserver>>>

Above file winperf_swyxserver for download
After a rescan of the services within the program, a new service called "Active Calls" is available to you, which you can also activate immediately.
