Diagnostic Logging in Exchange Server 2007

Unlike Exchange Server 2003, Exchange Server 2007 does not provide any GUI tool to configure diagnostic logging feature from the Exchange Console. Instead PowerShell cmdlets can be used to configure diagnostic logging levels. It might seem little tedious, but with a little understanding of PowerShell cmdlets, it will become much easier to manage the diagnostic logging.

There are five diagnostic logging levels:-

1. Lowest logging level is zero and is the default for all Exchange Server services except MSExchange ADAccess\Topology and Validation.

2. Low logs events with a logging level of 1 or lower.

3. Medium logs events with a logging level of 3 or lower.

4. Maximum logs events with a logging level of 5 or lower.

5. Expert logs events with a logging level of 7 or lower.

There are two PowerShell cmdlets which can be used with diagnostic logging.

1. Get-EventLogLevel

2. Set-eventLogLevel
