OK, A wee bit of background:
The Apdex method converts many measurements into one number on a uniform scale of 0-to-1 (0 = no users satisfied, 1 = all users satisfied). The resulting Apdex score is a numerical measure of user satisfaction with the performance of enterprise applications. This metric can be used to report on any source of end-user performance measurements for which a performance objective has been defined.
The Apdex formula is the number of satisfied samples plus half of the tolerating samples plus none of the frustrated samples, divided by all the samples:
Apdext = (Satisfied Count + Tolerating Count / 2) / Total Samples
where the sub-script t is the target time, and the tolerable time is assumed to be 4 times the target time. So it is easy to see how this ratio is always directly related to users' perceptions of satisfactory application responsiveness.
Example: if there are 100 samples with a target time of 3 seconds, where 60 are below 3 seconds, 30 are between 3 and 12 seconds, and the remaining 10 are above 12 seconds, the Apdex score is:
(60 + 30 / 2 )/ 100 = 0.75
So... I can get SLA's for all the steps in an app... can get little Check marks and Xs
Is there any way to generate an Apdex (Or Apdexish) number automaticlally?
Something like... Total Number of Checks for test/total number of test steps... would look nice on the Summary page, right?
