This object is a running counter of how many times the master/standby MPU has switched over since the system last started up. A rising count between checks signals MPU instability, such as flapping redundancy, prompting the admin to investigate hardware or software faults rather than treating it as a one-off event. For example, seeing this counter jump from 1 to 4 within a single day would alert an admin to repeated, abnormal MPU failovers worth escalating.
