Wer mittels Munin den Lighty tracken will, wird feststellen, dass es im gegensatz zum Apache-Status keine Anzeige der Idle-Servers gibt.
Aus diesem Grund habe ich mal fix einen Patch für die Version 1.5.0 geschrieben, der die Ausgabe der ?auto Page um die Anzeige von “IdleServers” und “Scoreboard” ergänzt.

[UPDATE]
Der Patch wurde im Changelog 2045 bzw. 2046 ins nächste Lighttpd Release aufgenommen.
