<probes>.subscribe command, can with this command be unsubscribed to. If there are zero users on the subscribed probe, some features can be turned off, potentially reducing run-time overhead.
Without any arguments, all probes which have been earlier subscribed too will be unsubscribed. To more precisely select the probes that should be unsubscribed to, there are a number of filters to reduce the scope.
The probe-kind filter specifies which probe-kinds to include. This can be the full name of a specific probe kind, or the string can be a partial kind, for example specifying cpu.exec_modes. would include all probe-kinds starting with this string.
The substr argument filter allows only probes which has a specific string in the probe name to be displayed.
To find probes in a particular object the object argument can be used, only showing the probes on that specific object.
In combination with the object argument the -recursive switch can be used to look at the probes that exists beneath the specified object, in the object hierarchy. This allows zooming in on the probes within a particular subsystem of the entire target system.
Each probe might be assigned with a number of categories represented as strings that describe some property of what they measure. The categories filter can be used to only include the probes which have all of the requested categories included.
Probes can returned different types when read. The probe-types argument allows only certain types to be shown.
