Why has the SQL Data Sharing Group error count decreased during the current interval for Detector for Db2 for z/OS (PDT).
When a PDT collection is stopped for one of the data sharing group members, it's metrics are subtracted from the current interval group metrics.
The first example below shows the metrics for a 2 member data sharing collection (Group <group>):
1) 19.0 ----- DETECTOR DS Group SQL Error Summary Display ----- 18/08/29 16:36

_ -305 404 2 18/08/29 16:36:42 18/08/29 16:32:49
The 2nd print is taken 4 minutes later, after the PDT collection was stopped for one of the members.
Notice the decrease in the Error count:
