Capture health check

The maintenance utility monitors the capture processes to determine whether they are in good health.

If the utility decides the capture processes are unhealthy, it performs a forced restart. The forced restart stops the capture processes, clears the runtime statistics that they collect, and then restarts them. The health check helps the capture processes recover from situations that degrade the effectiveness and performance of the capture processes. When the maintenance utility determines that capture is unhealthy and needs a restart, it writes a message to the maintenance log file to indicate this situation.
