# Version 1 - 1/19/11 - Initial release
|
|
#
|
|
# Munin plugin to graph the signal strength/quality for a HDHomeRun TV tuner.
|
|
# Developed and tested against a HDHR US Dual model.
|
|
#
|
|
# Requires the hdhomerun_config binary. It can be obtained from
|
|
# http://www.silicondust.com/support/hdhomerun/downloads/linux/
|
|
# Or if you are running Debian/Ubuntu:
|
|
# apt-get install hdhomerun-config
|
|
#
|
|
# Place the hdhomerun_ script in your munin plugins directory (usually
|
|
# /usr/share/munin/plugins) and create symlinks of the format
|
|
# "hdhomerun_<deviceid>_tuner<number>", such as hdhomerun_123456_tuner0.
|
|
# The deviceid can be obtained by running "hdhomerun_config discover".
|
|
# Alternatively, the script supports the suggest option which will
|
|
# scan for all HDHomeRun devices on the network and set up the symlinks.
|
|
# To do this, run:
|
|
#
|
|
# munin-node-configure --shell | grep hdhomerun | bash
|
|
#
|
|
# Note: It will assume you have a dual tuner model and set up links
|
|
# for tuner0 and tuner1. If you have a single tuner model, just delete
|
|
# the tuner1 link.
