This read-write Integer32 (0..65535) sets how often, in seconds, the PDU logs its metrics, with logging disabled entirely if the value is under 10. An admin raises or lowers this to balance how granular the historical current/power data is against how much log storage it consumes. For example, an admin investigating a suspected intermittent overload sets logInterval to a low but valid value like 10 to capture finer-grained current readings.
