This read-create CienaGlobalState object sets the administrative state, enabled or disabled, of an individual PM instance, per its description, controlling whether this specific instance is meant to be actively collecting, independent of the global cienaCesPmGlobalState switch covering the whole PM subsystem. Setting this to disabled on one instance stops that specific collection point without affecting any other PM instances configured on the device, which matters when only one particular monitoring point needs to be paused, for example during planned maintenance on that port, rather than all PM activity. An engineer temporarily silencing PM collection for a single port under maintenance, while leaving other instances running, would disable just this object for that instance rather than touch the global PM state.
