This holds the name of the global ERM resource policy currently applied system-wide; an empty string means no global policy is active, and an admin activates one by writing any policy name that already exists in cermConfigPolicyTable into this scalar. Because writing a zero-length string here removes the currently active global policy, this single object functions as the on/off switch and selector for whichever thresholding rules govern resource-exhaustion alerts across the entire device, not just one process. Setting this scalar to 'CPU-Memory-GlobalPolicy' would immediately apply that named policy's rising/falling thresholds to every resource owner on the box, while writing an empty string back out would revert the device to having no systemwide policy at all.
