%SYSTEM.Monitorabstract class %SYSTEM.Monitor
The %SYSTEM.Monitor class provides an interface for accessing the
System Monitor. You can Get/Set/Clear the system 'State' and 'Alerts' counter.
You can use it via the special $SYSTEM object.
You can call help to get a list of all entrypoints:
Returns the number of alerts posted to messages.log.
Clears the alerts counter and sets the system state = 0 (OK).
Clears the alerts counter.
Read messages from the alerts.log file. Returns the number of messages in 'Alerts' and an array of those messages in 'Messages'. 'LastAlert' contains the last message added to the alerts.log file.
This may be called periodically to get only recently added alerts. The first time GetAlerts is called, the caller should set LastAlert="". The caller may then retain the returned value and pass that LastAlert back in subsequent calls, to only retrieve messages added since then.
Set the system state. See State() for allowed integer values.
Returns the system state as an integer.
-1: System is hung
0: System state is OK
