A software circuit breaker observes an amount of free memory available in an application server and a duration of a garbage collection process performed by the application server. The application server executes an agent comprising a plurality of processes for monitoring performance of the application server. Based on the amount of free memory and duration of the garbage collection process, the circuit breaker anticipates a likely crash of the application server. In response to anticipating the likely crash, the circuit breaker disables one or more processes of the agent.

Mitigating crashes of an application server executing a monitoring agent

A system performs discovery and instrumentation of processes of an application based on process performance. The system includes one or more processors configured to: determine a duration score for a process indicating a relationship between a duration time for the process and a transaction time for a transaction including the process; determine an instrumentation threshold value; determine whether the duration score satisfies the instrumentation threshold value; and in response to determining that the duration score satisfies the instrumentation threshold value, instrument a second process invoked by the process to receive a second duration time for the second process when execution of the second process is detected in a second transaction trace of a second transaction. In some embodiments, the system prunes instrumented processes that primarily invoke subprocesses, and are thus unimportant for performance monitoring.
