Line-by-line Monitor Programming Interface
Programmers can also interface with the InterSystems IRIS MONITOR facility through the %Monitor.System.LineByLineOpens in a new tab class. Methods are provided for each menu option in ^%SYS.MONLBL. For example, start monitoring by calling:
Set status=##class(%Monitor.System.LineByLine).Start(Routine,Metric,Process)
You can select which routines and processes to monitor. You may also select any of the other standard performance metrics supported by the %Monitor.System classes. Use the Monitor.System.LineByLine.GetMetrics() method to retrieve a list of metric names:
Set metrics=##class(%Monitor.System.LineByLine).GetMetrics(3)
Selecting 3 as the parameter prints a list of all available metrics with a short description for each to the current device.
Stop monitoring by calling:
Do ##class(%Monitor.System.LineByLine).Stop()
You can retrieve the collected counts using the %Monitor.System.LineByLine:Result query, where the counters for each line are returned in $LIST format.
See %Monitor.System.LineByLineOpens in a new tab for more details.
