About monitor profiles
In TrueSight, monitoring profiles are profiles to which the monitor types (application classes) you want to enable are associated. Each KM contains multiple monitoring profiles and help to reduce unnecessary monitoring. Each monitoring profile is associated with a group of monitor types. The monitor types that belong to a profile are pre-determined. You cannot add or remove monitor types from a profile.
