For each subroutine of the selected routine(s), the report displays a tag number, the counts for each metric, and the subroutine<br />
label (if source code is available).<br />

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