# availability - defining what it means for a variable to be "available"
# There are two types of availability definitions: for an RRD or for an
# RRD on a particular host. The RRD may also be a wildcard RRD, like
# "df-*" or an instance of an RRD, like "df-/home". The definitions
# look like:
#
# rrd RRDNAME VARNAME CF RELATION THRESHOLD
# and
# host HOSTNAME RRDNAME VARNAME CF RELATION THRESHOLD
#
# The CF is one of LAST, MIN, MAX or AVERAGE, with rrdtool's usual
# meaning. The RELATION can be any one of: <, <=, >, >=, or =.
# The THRESHOLD is the number which the value of VARNAME must be
# in the correct RELATION. (Clear as mud.)
#
# As an example, take the following definition:
#
# rrd ping rcvd > 0
#
# This means that the variable 'ping' must be greater than zero for it
# to be considered "available". All time intervals where it isn't, or
# for which no data is available, are considered "unavailable".
#
# There are also two other record types: colors and thresholds. A colors
# record looks like:
#
# colors COLOR1 ...
#
# A thresholds line looks like:
#
# thresholds NUMBER ...
#
# and must have the same number of values as the colors line. Only one of
# each. Here's an example to make the use clear (I hope):
#
# colors avail1 avail2 avail3 avail4
# thresholds 99 98 95 90
#
# The colors line requires that the colors 'avail1', ... be defined in the
# colors config-file. The thresholds line specifies that if an availability
# is 99% or above, it should be colored 'avail1' color, 98% or above, use
# 'avail2' color, etc.
