The RTO measurement is the time interval during which the MES Middleware server is not available:
RTO = RTO (T2) – RTO (T1)
where
-
T1 = The time-stamp when the MES Middleware service cannot be detected. This also can be the time-stamp for when the "fault" is introduced into the system (e.g., Live Migration cutover, power off, network disabled or an operating system failure).
-
T2 = The time-stamp when the MES Middleware service is detected on the target machine (by using the services log on the target machine to determine T2).
If more than one clock is involved, be sure to either synchronize the clocks or understand the offset. In addition, MES Middleware service was monitored using Windows Performance Monitor (PerfMon).
