I found that the "Blocking sessions" graph shows me multiple sessions being blocked. But when i want to check which ones, the blockers list does not list all of them, if any.
Am I missing something?
What wait types do you see in the details section of the blockers tab?
Well this is awkward... I can't find the exact graph that I posted earlier, even after going through all days...
Anyway I found another example (now with date, so I can find it later)
After looking at the Blockers tab a little closer I found the "Blockers involved in deadlocks are not included." message. So when I checked the deadlock list, sure enough there were plenty...
So OK, lets drill a little deeper into the time dimension...
After that, the Blockers tab and the deadlock list is empty...
