Powershell Script - Using EMS Get-MessageTrackingLog + LogParser to Retrieve Top-Traffic Metrics for the Hubs in a Site

10/02/2013:All mail admins will occasionally see "odd" Exchange HubTransport queuing behavior for "unknown" reasons (I'll generally notice these type of events in response to monitoring alerts or via a looping get-queue monitoring script I run 24/7).

In most cases these little 'surges' come and go in a matter of minutes with no material impact or footprint. But on other occasions, you see something about the queuing that warrants further investigation into exactly what occurred:

• Possibly your interest is piqued due to the amount of mail that queued up (say a sudden spike into hundreds if not thousands of messages in normal delivery queues)
• Or possibly you want to check further due to mail rapidly piling up in queues where you traditionally should see little to no traffic (e.g. in the Unreachable queue).
