The health monitor subsystem comprises agent, manager, interface, and common processes. The agent process monitors a respective voice messaging system component operative on the host. The manager process monitors and manages detected faults on the host. The interface process exposes a status responsive to the host. The common process monitors and manages a platform of hosts. The health monitor subsystem enables monitoring at the component, host, and platform levels.
