This constitutes a large change in how we will parse different data
formats going forward (for the plugins that support it)
This is working off @henrypfhu's changes.
- Adds a client implementation using the prometheus go_client library
that exposes metrics.
- Adds a new type of output "ServiceOutput" which follows inline with
the "ServicePlugin", adding a Stop and Start method for the service
This change also requires the newer prometheus/client_golang code, so
the prometheus plugin needed to be changed.
Added the following to Godep:
- bitbucket.org/ww/goautoneg (in github.com/common/expfmt/encode.go)
- prometheus/common/expfmt (in plugins/prometheus.go)
- github.com/prometheus/common/model (in plugins/prometheus.go)
- github.com/prometheus/procfs (in github.com/client_golang/prometheus)
- github.com/beorn7/perks/quantile (in github.com/client_golang/prometheus)
X-Github-Meta: closes#306
Currently adding with time is broken, because InfluxDB does not support
using precision for timestamp truncation both with and without
timestamps. This will be re-enabled once we fix InfluxDB to use the
precision argument for truncation in all cases, and a "unit" argument
in the line-protocol for adding points with non-nanosecond stamps
Fixes#175
