Testing Siebel Business Applications > Execute Performance Tests > Measuring System MetricsResults collection should occur during a measurement period while the system is at a steady state, simulating ongoing operation in the course of a business day. Steady state is achieved once all users are logged in and caches (including simulated client-side caches) are primed. The measurement interval should commence after the last user has logged in and completed the first iteration of the business scenario. The measurement interval should last at least one hour, during which system statistics should be collected across all server tiers. We recommend that you measure the following statistics:
The analysis of the statistics starts by identifying transactions with unacceptable response times, and then correlating them to observed numbers for CPU, memory, I/O, and so on. This analysis provides insight into the performance bottleneck. |
