This section describes a feature in peepd whereby the server can record incoming events for later playback and a closer listen. The events are stored in ''round-robin'' fashion in a playback file specified on the command-line. The maximum number of events is set as a define in the playback.h file in the server code and defaults to 3200 events. The size of the plaback file varies greatly with the amount of XML data that might be sent through the messaging structure but 3200 events should generate a playback file well under 1 MByte. There are five command-line options used to get the playback code running:
-playback-mode -record-mode -record-file=-start-time=
-end-time=
The recording file defaults to /var/log/peeplog, which is set via a #define in main.h. Otherwise, events are recorded to the file specified by the -record-file option. peepd does not do recording by default. To kick peepd into recording mode, you need to use the -record-mode option and optionally the -record-file option. An example:
./peepd -record-mode -record-file=test.log
Then to playback, you need to specify -playback-mode and peepd will playback the events in the log and then exit. As always, -record-file is optional. An example:
./peepd -playback-mode -record-file=test.log
Since there are many events in a single log file, you'll probably
want to play back sounds between a specific time. peepd lets
you do this through use of the -start-time=
and
-end-time=
options. If a -start-time is given
without an -end-time, peepd will play back from the start
time to the last event in the file. The date format used is the same as the
output of date except without the specifier for EST/PST. The date format
used is defined in playback.h as a string to strptime. An
example:
./peepd -playback-mode -f testlog -t 'Wed Mar 14 22:15:45 2001' -e 'Wed Mar 14 22:17:00 2001'
Note that the 24 hr time clock is used. It's less ambiguous and simpler.
