Considerations
• To receive status changes for local processors
MONITORNET only provides notification of status changes for remote processors. To receive
notification of status changes for local processors, an application process must still call
MONITORCPUS.
• Change in status of network processors
A process that has enabled MONITORNET receives a system message (-8, -100, -110, -111,
or -113) on $RECEIVE whenever a change in the status of a remote processor occurs. The
processor status bit masks have a 1 in bit cpu number to indicate that the processor is up
and a 0 to indicate that the processor is down. See the Guardian Procedure Errors and
Messages Manual for details on system messages sent to processes.
