Understanding metrics values.
Hello,
could you correct me if I'm wrong:
Response time = start of A until end of E
Duration = start of A until end of G
Exec sum = sum of all (ie A+B+C+D+E+F+G)
CPU sum = sum of time when CPU is working (must be <= A + C +E +G)
Wait Sum = sum of time when thread wait on a specific object to be notified. (ie Object.wait)
Suspension Sum= sum of time when thread are suspended because GC activity
Sync sum = thread wait another a resource (ie synchronized )
IO = Exec sum – CPU Sum - Wait Sum – Suspension Sum – Sync sum
Is there a way to know the time spent in B, D and F (ie communication layer.
Thanks

B, D, and F are what is called "Inter-tier time" and you will get this in the Transaction Flow Diagram as long as you have an agent on both ends of each communication layer.
