OPTIONS

       -h, --help
               Display help message.

       -c, --config=DIR
               Use the config directory DIR instead of /etc/tirex.

       -l, --list=FILE
               Write list of tiles to FILE. See below for format.

       -s, --stats=FILE
               Write stats about tiles to FILE. See below for format.

       -z, --minz=i
               Start processing at min. zoom level i (default=0)

       -Z, --maxz=i
               Stop processing at max. zoom level i (default=19)

DESCRIPTION

       Walks  recursively  through  the tiles directory for the given MAP and checks for wrong directory or file
       names or files that can't be accessed. If problems are found, messages are written to STDERR.

       When the --list and/or --stats options are given, it outputs information about each tile and/or generates
       statistics, respectively. The list and stats are written to the filenames given, if you give '-'  as  the
       filename STDOUT is used.  You can only use STDOUT for either the list file or the stats file.

       Caution:  This command will go through all metatiles on your disk and stat each file. On a lightly loaded
       machine with lots of RAM this can go pretty quick, but under high IO loads it might  take  a  long  time.
       Take this into account if you want to run it regularly from cron or similar.

LIST FILE FORMAT

       The list file is in CSV format with one line per metatile. The fields are:

       age     Age of metatile in seconds.

       size    Size in bytes of the metatile.

       blocks  Number of blocks used for this metatile.

       metatile
               Description of metatile. Format: map=foo x=8 y=0 z=10

       This data can be read with other programs to create statistics etc.

STATS FILE FORMAT

       The  stats  file  is  in JSON format. It contains a hash with the names of all maps as keys and a list of
       zoom levels as their values. For each zoom level there is a nested hash containing the statistics:

       count - Number of tiles
       maxage - Maximum age in seconds
       maxblocks - Maximum number of blocks
       maxsize - Maximum file size in bytes
       minage - Minimum age in seconds
       minblocks - Minimum number of blocks
       minsize - Minimum file size in bytes
       sumage - Sum of ages in seconds
       sumblocks - Sum of number of blocks
       sumsize - Sum of file size in bytes

       The sumage, sumblocks, and sumsize values can be divided by count to get the average.

       This file can be displayed on a human readable format with the Program  tirex-tiledir-stat.  It  is  also
       read by several Munin plugins.

FILES

       /etc/tirex/tirex.conf
               The configuration file.

DIAGNOSTICS

       Returns  0  if  no  errors were found or 1 if there were errors. If there were errors parsing the command
       line 2 is returned.
