Changing the metric threshold in EM should do it. It should be easy to
confirm in EM:
1) Go to DB target homepage.
2) Oracle Database -> Monitoring -> Metric and Collection Settings
3) Change the value for "Blocking Session Count"
4) Click OK at the bottom of the page
There might be one more "OK" to click. After some short delay, poll the
DBA_THRESHOLDS view on the target again and you should see it.
