Subject Munin plugins stupid question
Date Wed, 22 Jun 2011 21:24:10 GMT
Heya!

I know I should probably be able to figure this out on my own, but...

The Cassandra Munin plugins (all of them) define in their storageproxy_latency.conf the following
(this is from a 0.6 config):

read_latency.jmxObjectName org.apache.cassandra.db:type=StorageProxy
read_latency.jmxAttributeName TotalReadLatencyMicros
read_latency.type DERIVE
read_latency.cdef read_latency,3000000,/

Ok... Why is the derived difference divided by 3 million?  A three-second update interval?
