Question #271536 on Graphite changed:
https://answers.launchpad.net/graphite/+question/271536

    Status: Open => Answered

Jason Dixon proposed the following answer:
Without knowing how you intend to consume the data, you could use the
removeAboveValue() function which excludes any values above the defined
threshold.

http://graphite.readthedocs.org/en/0.9.12/functions.html#graphite.render.functions.removeAboveValue

Example targets:
asPercent(collectd.graphite.memory.memory-used, sumSeries(collectd.graphite.memory.memory-*))
removeAboveValue(asPercent(collectd.graphite.memory.memory-used, sumSeries(collectd.graphite.memory.memory-*)),14.4)
