ME ( Metric Extension ) Metric Is Not Collected For Some Databases

By default, ME metric will not be collected if associated target has a severity on response:state metric. So override this default by explicitly choosing Advanced option while creating ME.

For some databases, ME ( Metric Extension ) is not collecting data. But for the rest databases, it is working fine.

Checking the ME ( Metric Extension ) definition and found an advanced option is not selected.

After creating a new version of this ME ( Metric Extension ) by checking this mentioned option, it works fine.

The reason is  this database has frequent Warning/Critical response metric alert. like  :
