New question #282148 on Graphite:
https://answers.launchpad.net/graphite/+question/282148
I've installed the latest megacarbon branch along with my standard Graphite
install. I'm trying to get the aggregator up and running but struggling to
find much in the way of documentation. I have 2 write carbon daemons and a
single relay on running on the same node.
Both of my write carbon daemons are setup as writers only i.e.
#/opt/graphite/conf/carbon-daemons/writer-(1,2)/daemon.conf
PIPELINE = write
My relay is setup to filter, relay and aggregate:
#/opt/graphite/conf/carbon-daemons/relay/daemon.conf
PIPELINE = filter,aggregate,relay
Within my relay aggregation rules I have the following entry:
test.aggregate.all.requests (60) = sum test.aggregate.requests
When I try and submit a metric matching this input mask I receive the following
error in the relay console.log:
18/01/2016 11:12:05 :: Unhandled Error
Traceback (most recent call last):

I've struggling to understand where this configuration setting needs to be
placed?
