This read-only value reports the index of the newest (most recently added) trap occurrence currently stored in the Trap Log; a value of zero means no trap has been logged yet. An admin polls this to detect when new traps have arrived in the log since the last check, by comparing it against a previously observed value. For example, an increasing trpzTraplogNewestTrapIndex between two polls tells the admin new trap occurrences have been logged in the interim, even without receiving the traps directly.
