In October we upgraded our dynaTrace installation from 6.3 to 6.5 and noticed that the metrics for perceived render time seems to have went down pretty substantially directly after the upgrade. Since we have no other (known) changes, and the difference seems to correlates to the upgrade date we are curious if someone else also have noticed something similar, or if there are some known changes in how the calculations for perceived render time are performed in between version 6.3 and 6.5? Unfortunately this issue didn't really surface until now, and the visit detail data for this time period isn't available any longer (therefore the question if there are any known changes between the version that can explain the behaviour we are seeing).
Solved! Go to Solution.
Which update version of Dynatrace AppMon 6.5 do you have?
It seems to be a know issues which has been fixed in the 6.5.7 version and I guess it was started from the version 6.5.4
JLT-154926 - Perceived Render Time module doesn't capture images if they are loaded too quickly.
Few other critical fixes and improvements done for the Perceived Rander Time also.
