metrics

The metrics package provides a simple metrics "Reporter" interface which allows the user to submit counters, gauges and timings (along with key/value tags).

Implementations

• Prometheus (pull): will be first
• Prometheus (push): certainly achievable
• InfluxDB: could quite easily be done
• Telegraf: almost identical to the InfluxDB implementation
• Micro: Could we provide metrics over Micro's server interface?

Todo

• Include a handler middleware which uses the Reporter interface to generate per-request level metrics
  • Throughput
  • Errors
  • Duration
