Deferred Update of MSreplication_monitordata

Hello,

for monitoring reason I query daily the system table MSreplication_monitordata like this:

 select last_distsync from distribution.dbo.MSreplication_monitordata where publication ='Publ_Prod_TAGDR01'

Unfortunately it seems that the whole table is not updated automatically after the subscriber jobs finished run. Though after starting the Replication Monitor of the Management Studio and running again the same query, then it shows the current information of the last run.

My environment: SQL Server 2005 Standard Edition on distribution side, where the monitoring runs, and Express Edition at the Subscriber. We implemented Snapshot distribution with push subscription because of Express Edition. The 137 Subscriber Jobs runs every morning in a period of approx. one hour.

Any suggestions why the system table doesn't show the current data automatically? Did I traped in a bug?

Regards

Peter
