Runtime or Health Monitoring Diagnostics
Runtime diagnostics are also called health monitoring (HM) diagnostics. These diagnostic tests provide
information about the health of a live device. They detect runtime hardware errors, memory errors, the
degradation of hardware modules over time, software faults, and resource exhaustion.
Runtime diagnostics are nondisruptive and run in the background to ensure the health of a device that is
processing live network traffic. You can enable or disable runtime tests. You can change the runtime interval
for a runtime test.
Recommended best practice: Do not change the runtime interval from the default value.
Note
The following tables describe the runtime diagnostic tests for a module and a supervisor.
