Exchange System Health Test

The Exchange System Health Test monitors health sets (groups of monitors) and health information on your Exchange 2013/2016 server, verifying the state of each health set’s monitors. Monitors that are similar or are related to a component’s architecture are grouped to form a health set. Health sets provide the health information for applications and services such as Outlook Web App, Exchange ActiveSync, the Information Store service, content indexing, and transport services on your Exchange 2013 and Exchange 2016 servers.

This test allows you to ensure the health state of health set (whether health or unhealthy).

You can run the system health test against Exchange 2013 and later.

Test prerequisites

For example, to run Exchange 2007 Server Health on one server, the maximum space required (with default parameters) would be:

•
Raw data: 1.2 KB x 1 day x 48 bi-hourly values= 58 KB
•
Hourly data: 1.2 KB x 7 days x 24 hourly values = 202 KB
•
Daily data: 1.2 KB x 30 days x 1 daily value = 36 KB

For example, you have a medium-sized environment with the following characteristics:

•
Monitoring 50 Exchange servers
•
Each Exchange server has an average of 5 stores
•
Each Exchange server has an average of 10 queues
•
Running one of each test using the default counters
•
Using default monitoring of 30 minutes for all tests
•
Using default data retention of 7 days for hourly aggregation data
•
Using default data retention of 30 days for daily aggregation data
•
Running Internal Server Delivery Health fully meshed with all servers

The approximate space required for historical data would be:
