Event::Stats is a Perl module for event loop statistics. Instrument the Event module in order to gather statistics.
Determines whether statistics are collected. Arithmetically adds $yes to the usage count. Stats are enabled while the usage count is positive.
$round_sec = round_seconds($sec)
Statistics are not collected in one second intervals. This function converts a *desired* time interval into an *available* time interval. Units are in seconds.
$elapse = total_time($sec)
Due to long-running callbacks, measurement intervals may take longer than expected. This function returns the actual clock-time for a given measurement interval.
($rans, $dies, $elapse) = idle_time($sec)
($runs, $dies, $elapse) = $watcher->stats($sec)
Return statistics for the last $sec seconds of operation. Three numbers are returned: the number of times the callback has been invoked, the number of uncaught exceptions and the number of seconds spent within the callback. Also see NetServer::ProcessTop.
Useful for debugging. XXX
