## Be sure to correctly edit the STATION_CALL, XASTIRDIR, and LOGDIR variables

##

## STATION_CALL: The callsign used by Xastir (include suffix if one is in use)

## XASTIRDIR: The directory where Xastir's data, config, etc files are found.  Typically ~/.xastir

## LOGDIR:  Logs are typically stored in ~/.xastir/logs.  Ensure that permissions are set appropriately to allow the munin user to read these logs

# Location of active instance of Xastir

XASTIRDIR="/home/USERNAME/.xastir"

# Grab the station's callsign from Xastir config

# this currently does not derive the station call correctly when called by the server, but works using munin-run...

#STATION_CALL=`grep ^STATION_CALLSIGN:.* $XASTIRDIR/config/xastir.cnf | awk -F":" '{print $2}'`

STATION_CALL=""

# Location of Xastir's logs (this can be a symlink to where Xastir actually writes the logs)
