Maintenance plan duration shown in history

Question

Here is an export of our sql 2005 maintenance plan history

Date,Source,Severity,Plan Name,SubPlan Name,Task Name,Duration
06/07/2009 05:08:29,,Unknown,Weekly optimisation,Subplan_1,,05:08:25
06/07/2009 05:07:41,,Unknown,,,Shrink Database Task (localhost),00:00:48
06/07/2009 04:50:40,,Unknown,,,Rebuild Index Task (localhost),00:16:41
06/07/2009 00:00:37,,Unknown,,,Purge DataStoreException (localhost),00:01:08
06/07/2009 00:00:37,,Unknown,,,Truncate HelpDeskMonitoring (localhost),00:00:07
06/07/2009 00:00:37,,Unknown,,,Execute SQL Server Agent Job Task (localhost),00:00:00
06/07/2009 00:00:05,,Unknown,,,Back Up Database Task (localhost),00:00:32

Why the duration of each steps is fast, but the overall maintenance has taken 5h ? How can I find which task is taking that amount of time...

Answer 1

Look at the start times and you will see that Purge DataStoreException Started at :37 and the next step started at 5:07.

This is not a standard SQL maintenance task, but something custom you have inserted, correct?

What is it doing?
