GPXLOGGERD(8) BSD System Manager's Manual GPXLOGGERD(8)NAMEgpxloggerd — GPX logging daemon
SYNOPSISgpxloggerd [-dhVv] [-D level] [-f template] [-u user [:group]]
[-p pidfile] [-m meters] [-M meters] [-a degrees]
[-I interval] [-i timeout] [server [:port [:device]]]
DESCRIPTION
The gpxloggerd is a tiny daemon that connects to GPSD(8) and logs
received fix information in the GPX format. By default the gpxloggerd
connects to GPSD(8) at the localhost:2947 and logs to stdout GPX data for
all GPS devices served be the daemon.
The options are as follows:
-h Print usage and exit.
-V Print version number and exit.
-v Be as verbose as possible when writing GPX log. For now this
means logging of ⟨fix⟩, ⟨sat⟩, ⟨hdop⟩, ⟨vdop⟩ and ⟨pdop⟩ fields,
which bloats size of produced GPX significantly. By default this
option is turned off, and only coordinates, time and elevation
are logged.
-d Detach from terminal and become a daemon.
-D level
Set the underlying libgps(3) library to the given debug level.
-f template
Write data to the given file instead of stdout. The template
isn't a bare filename, but can be a format for the strftime(3).
-u user [:group]
Lower the daemon priveleges to the specified user and group.
-p pidfile
Write the daemon pid to the specified file.
-m meters
Suppress logging of track segment in case if it lays within the
specified distance away from the previous logged track segment.
This option is useful to avoid polluted GPX traces at parking
lots and other places, where vehicle stands still for long time.
The option is turned off by default.
-a degrees
Suppress logging of track segment unless the course (azimuth,
bearing) of the vehicle has changed to a value equal or greater
than the specified angle in degrees. This option is useful to
make traces on straight roads more sparse. The option is turned
off by default.
-M meters
Set maximum track segment length. This option is meaningful only
in conjunction with the -a option. The default value is 200
meters.
-i timeout
Start new track if the time jump between current fix and previous
logged one is above the timeout. By default timeout value is 300
seconds.
-I interval
Specify logging interval between trackpoints in seconds. The
default one is one second.
When the gpxloggerd daemon receives SIGHUP it finalizes GPX in the cur‐
rent output file, closes it and then starts a new one using the config‐
ured template as a file name.
