This change adds support for diagnostics by decomposing the existing
interface into two interfaces -- one for stats, and the other for
diags. It also adds some basic monitor of system, network, and the Go
runtime.
* Capitalize first letter of message
* Log all services staring consistently
* Remove some extraneous log statements in meta.Store
* Log data dirs for meta, data and hinted handoff
Previously there was a batcher per connection and each batcher was
flushed when the connection was closed. This didn't have much of an
effect when multiple clients connected and disconnected since it would
flush the batch immediately. It also did not help UDP traffic.
Instead, there is now a shared batcher for the service so that multiple
connections will not cause frequent flushes.
Provides a little more flexibility in controlling the parsed
metric names for metris like:
servers.localhost.cpu.cpu0.user
Previously, you could only use a single field like "cpu", "user"
or a wildcard to match "cpu.cpu0.user". You can now pull out "cpu"
and "user" and join them together in the metric name using a custom
separator character. By default this is ".".
