In this post (the second of six in the series), we’ll look into time synchronization on important servers on the Zylinc system.
Background: Many organizations want to be able to monitor how their critical IT and communications solutions perform, so that they can quickly deal with any potential problems before many users become affected. If you work in IT operations or a similar function, and your organization uses Zylinc, this blog series is for you. It covers what you need to know if you’re going to monitor the operational status of a Zylinc solution.
A Zylinc backend system basically has two parts: a Windows part and a Linux part.
The Zylinc Windows Application Server is the server that runs the Windows-based parts of the Zylinc solution.
The Zylinc Media Server is the server that runs the Debian Linux-based part of the Zylinc solution. The Media Server answers calls to queues, plays music on hold, makes interactive voice response (IVR) menus work, etc. The Media Server also hosts the browser-based Zylinc Administration Portal in a Tomcat service that runs on the Linux operating system.
Correct time synchronization is critical on both the Windows Application Server and the Media Server. That’s why it’s a very good idea to monitor that time synchronization works as expected.
On Windows, time synchronization is usually handled as a part of the domain membership, and event log errors are available when you need to monitor the state of the time synchronization service.
On the Linux-based Media Server, time synchronization relies on internal or external NTP (Network Time Protocol) servers. Because you can’t monitor the Linux NTP daemon status directly on the Media Server, we recommend that you monitor the state of the NTP servers that you use.
The next post in this blog series will be about monitoring Zylinc Media Server services. Here’s an overview of the rest of the series:
- Monitor Zylinc Media Server services
- Monitor relevant Windows services
- Monitor relevant Tomcat services on Windows
- Monitor SQL Server availability
