Simple Go agent to ingest streaming data from Turbine via SSE and push it into StatsD as a gauge or to InfluxDB as a series.

Property Munging

All keys related to properties (such as max threadpool size, queue lengths, etc.) are stripped by default.

Properties of the following patterns are kept:

  • current*
  • rollingCount*
  • latencyTotal_*
  • isCircuitBreakerOpen

Normal keys are pushed under my-prefix.my-cluster.MyCommandImpl.rollingCountSuccess

Latency histograms are pushed under my-prefix.my-cluster.MyCommandImpl.latencyTotal.xx_pct

isCircuitBreakerOpen will be either 0 or 1.

Additionally, all numeric metrics are divided by the number of reporting hosts. This is because Turbine simply sums all metrics, including percentiles.

StatsD caveat

All metric values are cast from float64 -> int64.

Running

Create a config.toml with your config

# Turbine connection information
host = "turbine.yourcompany.com"
port = 80
tls_enabled = false
clusters = ["cluster1", "cluster2"]

# Backend to stream updates to, 'influxdb' or 'statsd'
backendtype = "influxdb"

[statsd]
host = "127.0.0.1"
port = 8125
prefix = "hystrix"

Build the project

go build

And deploy the resulting binary & config

./crankshaftd

Or run with a different config

./crankshaftd dev.toml
