### Usage:
### define the tiles for the dashboard in sections

# Settings:
# example:
# --------------------
# [settings]
# show_top_bar=True
# --------------------
# options:
#   show_top_bar (True / False) [optional]
#     If True, the dashboard will show the current date and the time on the top
#     if False, the dashboard will not show a top-bar
#   default: True
#   hint: the top-bar has got a height of 5%!

[settings]
show_top_bar=True

# Tiles:
# example:
# --------------------
# [tile1]
# type=mon
# source=192.168.0.2
# status=up
# --------------------
# options:
#   type (mon / d3js) [required]
#     tells the program what kind of tile you need.
#     a "mon" tile can be used for IT infrastructure monitoring purposes
#     a d3js tile can be used to display a chart
#   default: -
#
#   source (<IP> or <FQDN>) [required for mon-types]
#     ONLY FOR MON-Type tiles!
#     tells the tile which resource to watch
#   default: none
#
#   status: (up / down) [required]
#     ONLY FOR DEBUGGING PURPOSE - WILL BE REMOVED LATER
#     simulates up and down events for mon-type-tiles

[tile1]

source=192.168.0.2

[tile2]
