This true/false flag indicates whether UCS Manager considers the currently sampled CPU-load and memory-usage statistics for the fabric-interconnect switch's onboard OS not fully trustworthy, for example because the sample was collected under unusual conditions. An administrator building automated alerting on switch load or memory should exclude or flag samples where suspect is true, since acting on a low-confidence reading could trigger a false alarm. For example, a SystemStats sample marked suspect right after a supervisor failover would tell an operator to disregard that particular reading rather than treat it as evidence of a real load spike.
