The stamp log function is used to insert a line into any System Monitor trace that is running. The line in the trace indicates the date, time, user name and extension plus additional information. The line is prefixed with LSTMP: Log Stamped and a log stamp number. When invoked from a Avaya phone with a display, Log Stamped# is also briefly displayed on the phone. This allows users to indicate when they have experienced a particular problem that the system maintainer want them to report and allows the maintainer to more easily locate the relevant section in the monitor trace.
