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? /Janne
