How to create daily reports with System Center Operations 2012 and PowerShell - Part 2

This second entry in this series of blogs delves into reporting on database health. It also aims to explain how PowerShell can be used to extract information from Operations Manager to show the health state of the operations and data warehouse databases and then output this onto an HTML page.

The focus on the Operations Manager databases reflects its key importance in the running of System Center Operations Manager 2012. The operational database contains all configuration data for the management group, it also stores all monitoring data that is collected and processed for the management group. The data warehouse database stores monitoring and alerting data for historical purposes. Information that is written to the Operations Manager database is also written to the data warehouse for long term storage. For more information on the Operations Manager infrastructure please visit Operations Manager Key Concepts at the link provided below:

Subsequent posts will continue to build on this report to provide key reporting of system health.

Now run using the command from the previous blog to start the script, replacing parameters as required, as illustrated in this example:

PowerShell.exe Daily-Report.ps1 MSServerName c:\scripts Daily-Report.htm

This will produce a report similar to the below :
