Misatched counts in metric browser

[John.Gregg]

All,

In the metric browser, I see a DB appear under Backends|Discovered backend call...  I also see the same backend under Overall Application Performance|My Tier|External Calls|Call-JDBC to Discovered backend...

The calls per minute graphs are approximately the same shape, but counts are not even close.  Under backends, the counts are much higher, like 5x higher.  This app only has 1 active tier.

Why is there such a large difference in counts?  I would like to get a breakdown of DB calls per tier, but the numbers seem low.

thanks
