System and method for comprehensive performance and availability tracking using passive monitoring and intelligent synthetic activity generation for monitoring a system

Abstract

One or more passive collectors watch a system's real activity confirming normal responses to requests. This passive monitor may have other purposes such as measuring real performance, and determining normal completion of requests which provides complete and accurate performance and availability of the monitored system. When the passive monitoring no longer detects actual activity, the preferred embodiment automatically triggers the execution of synthetic activity which simulates the real usage of the system. This active monitoring determines the state of the usage of the system. If the simulated use of the system results in an abnormal completion of the activity, an outage is recorded. The simulation occurs on a regular interval until the passive monitor sees real normal activity.
