Redis Timeseries Metric

I've been playing around with trying to make it as simple as possible to start logging a few metrics with as little effort in setup as possible.

As I was working on Papertrail I came up with a couple interesting ideas, some of which were inspired by OpenTSDB.

Storing metrics

In this example we are pretending we're processing emails as background jobs and would like to track how many we've sent over time.

samg

class ApplicationController
  private
  def newrelic_metric_path(action_name_override = nil)
    format_string = case
      when request.format.html?
        '.html'
      when request.format.json?
        '.json'
      when request.format.xml?
        '.xml'

>> engine = ArelBack::Engine.new(ar.connection, Arel::Visitors::MySQL)
>> table = Arel::Table.new(ar.table_name, engine)
>> table.project(Arel.sql('*')).to_sql
=> "SELECT * FROM `awesome_table` "
>>

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

### Generic Dockerfile demonstrating good practices


### Imports

# Bad-ish, we do not need Ubuntu for this, nor do we want latest if we are using in a build system, predictable is better
FROM ubuntu:latest

# Better, using a small image since our app has no dependency on Ubuntu
FROM alpine:3.3
