Microsoft Exchange Server Monitoring

Microsoft Exchange Server is a messaging platform that provides secure email and scheduling tools for individuals and organizations and other useful tools to simplify communication and collaboration accross users. It is available as a hosted service as well as on-premise software.

What You Can Monitor

This Opspack allows you to monitor all the metrics you need to efficiently run a Microsoft Exchange Server, providing service checks for high level status information about services, mailflow statistics and client connectivity, as well as important metrics for the exchange database.

Host Templates

The following Host Templates are provided within this Opspack. Click the name of each Host Template to be taken to the relevant information page, including a full Service Check description and usage instructions.

Exchange - Connectivity - ActiveSync Requests	Shows the number of HTTP requests received from the client via ASP.NET per second. Determines the current Exchange ActiveSync request rate. Used only to determine current user load.	N/A	N/A

Microsoft Exchange Server Monitoring Prerequisites

Opsview Monitor Version 6.2.0 or newer - Exchange Server 2016 or Exchange Server 2019, other versions may be compatible but are not officially supported.

Known Issues

The 'Exchange - Connectivity - Web App Connected Users' service check may report inconsistently high values sometimes, this is because the value returned from the performance counter is incorrect. A possible workaround is to restart IIS by running the following command: shell iisreset
