This read-write parameter controls how the TSUIQ collects and stores statistics for this PVC, with options like 'auto' (track if memory allows) or manual (require explicit enablement). Network engineers use this to balance monitoring detail against memory consumption, especially on devices with many PVCs or limited RAM. For example, setting a high-priority PVC to manual stats collection ensures detailed counters are always maintained, while setting lower-priority PVCs to 'auto' allows the device to skip stats when memory is tight.
