If the custom agent monitor does the basic as well as detail monitoring, then the basic monitoring code must be conditional. This avoids scheduling of basic monitoring if only detail monitoring is required to be scheduled. VCSAG_GET_MONITOR_LEVEL api can be used to check if basic, detail or both monitoring is required to be scheduled.

Using api VCSAG_GET_MONITOR_LEVEL monitor entry point can decides whether to perform basic and detail monitoring based on the values of MonitorFreq and LevelTwoMonitorFreq attributes respectively.
