Editing Software performance testing (section)

=== Performance monitoring ===
This forms the other face of performance testing. With performance monitoring, the behavior and response characteristics of the application under test are observed. The below parameters are usually monitored during the a performance test execution

Server hardware Parameters

* CPU Utilization
* Memory Utilization
* Disk utilization
* Network utilization

As a first step, the patterns generated by these 4 parameters provide a good indication on where the bottleneck lies. To determine the exact root cause of the issue, [[software engineer]]s use tools such as [[Profiler (computer science)|profilers]] to measure what parts of a device or software contribute most to the poor performance, or to establish throughput levels (and thresholds) for maintained acceptable response time.
