# Definition Syntax:
#
#    [name]
#    pattern = regex
#    retentions = timePerPoint:timeToStore, timePerPoint:timeToStore, ...
#
# name: Arbitrary unique name for the rule
# pattern: Regular expression to match against the metric name. For syntax see:
#          https://docs.python.org/3/library/re.html#regular-expression-syntax
# retentions: Retention schema for the metric
#
# Remember: To support accurate aggregation from higher to lower resolution
#           archives, the precision of a longer retention archive must be
#           cleanly divisible by precision of next lower retention archive.
#
#           Valid:    60s:7d,300s:30d (300/60 = 5)
#           Invalid:  180s:7d,300s:30d (300/180 = 3.333)
#
# This retention is set at the time the first metric is sent.
# Changing this file will not affect already-created .wsp files.
# Use whisper-resize.py to change existing data files.
