NAME

       tirex-tiledir-check - check tile dir

SYNOPSIS

       tirex-tiledir-check [OPTIONS] MAP

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.
