The Health Monitor API
The libmsvcs-pmon library provides monitoring functionality to the data and control CPUs on MultiServices PICs. The information is aggregated and provided to the Routing Engine.
Features include:
- Heartbeat APIs for control and data plane applications to enable runtime status detection. If a process misbehaves, the health monitor takes the action for which the process has registered.
- Monitoring gives a process a way to get the update about the health of a different process that has already registered for heartbeat monitoring.
- Service name resolution provides a dynamic way for any server process to advertise its IP address and the port number internally to the other processes.
- Synchronous and asynchronous ways exist to retrieve and control the high-availability notification and state for the
rms interface and its children.
