Graphs of Average Transaction Response Time & Percentile Transaction Time are not consistent
The Analysis graphs should be consistent. Either all graphs should have thinktime included or all graphs should not include thinktime. The graph of Average Transaction Response Time does not include thinktime whereas the graph of Percentile Transaction Time has thinktime inlcuded in it.
To fix this issue download this patch from the support website.
patch_for_percentile.zip — Patch.
Unpack it into folder where you install LR (the folder which contains bin subfolder) ie. C:\Program Files\HP\LoadRunner
This patch will solve problem with newly created sessions. The Analysis sessions that were created BEFORE applying this patch will not be affected and issue for them will remain.
So, please recreate your sessions from raw results if needed.
Alternatively, you can try the workaround given below:
Just create the .lra file from the results folder by clicking the .lrr file. We see that Percentile transaction response time has thinktime included in the transaction, whereas for the same transaction Average Response Time Graph is showing a much lower value. This is due to thinktime not being included for Average Response Time graph.
Create the Analysis file (*.lra file) from the .lrr file by clicking on it and do the following:
View -> Set Filter/Group by -> Click on the right side of Think Time,
You will get a pull down menu, choose include Think time. In the original graph of Average Transaction Response time, think time was not included.
Once think time is included, you will see for transactions the average response is about the same value as Percentile transaction response time .
The two graphs are now comparable.
