Hi, I have been running DPA for a month now, and we have been working on getting our (pretty appalling) SQL Wait times down.
We have been making progress, and released a new version of our app early on Tuesday 10th December.
I looked at the Total Wait Chart on the trend screen this morning (11th Dec) and thought "Yay! we've cracked it" - total wait for Tuesday 10th Dec is shown as 20mins, down from around 80mins the previous day. Have a look at this screen grab:
Then I looked at the Daily Wait chart for yesterday and thought "Hang on, this looks much like it did the day before":
Indeed, the Total Wait time during JUST the one hour slice at 3pm (highlighted) was over 17 minutes, and a rough add-up of the total wait time for the whole of the 10th December indicated that the total wait was indeed still around 80 minutes, the same as the day before.
So. What is going on here? Why is the Total Wait trend chart misleading or just plain wrong??
