the definitive roadmap

FnordMetric v1.0

================

ROADMAP

-------

  > Core: Backend

    - FnordMetric::Timeseries (min/max, values, punchcard, to_histogram etc)

    - split up fnordmetric.namespace block into multiple files

    - caching

    - use rack websocket instead of em websocket

    - gauge garbage-collection

    - store per-session-data

    - callback on session-flush

    - fix specs

    - new full_example.rb

  > Core: Frontend

    - show notification when connection lost

    - reconnect on disconnect

    - gauge-view: interval selection dropdown

    - overview view: gauge list (a'la github graphs landing)

    - overview view: num active users, system stats

    - fix pie widget

    - fix html widget

    - fix toplist widget

    - formatter: num, time, currency, percent, time_of_day

    - fix hash-history fu

    - minimize/pack js

    - put images into one sprite

    - nice empty states

  > Eventfeed Gauge

    - fix

  > Timeseries Gauge

    - timeseries-gauge/widget: set resolution via "tick buttons" 

    - timeseries-gauge: realtime tab w/ moving average

    - timeseries-widget: tooltip -> show key noun

    - timeseries-gauge: calculate option (sum, average, progressive_sum)

    - timeseries-gauge: incr_counter / incr_divisor for avg

    - timeseries-gauge: overview realtime gauge

    - timeseries-gauge: overview series weights

    - timeseries-gauge: overview all numbers

    - timeseries-gauge: punchcards

    - timeseries-gauge: cmp. w/yesterday option

    - display trends

  > Distribution Gauge

    - render std. deviation

    - render max/min/avg over time

    - display trends

  > Toplist Gauge

    - here be dragons

    - display trends

    - show multiple keywords

  > Timeseries Widget

    - timeseries-widget: cardinal on/off should be skeuomorph

    - timeseries-widget: moving average/smoothing option

CHANGELOG

---------

  > improved ui

  > highcharts is dead, long live d3.js :)

  > websockets instead of ajax

  > new gauges: timeseries, toplist, distribution (anti-repetition!)

  > new widget: ...

  > splitted up code into acceptor, web, worker etc.

  > splitted up javascript code

  > refactorings, no server-side rendering

  > less ram usage / garbage collection / single tick

  > fnordmetric:announce redis pusub event-data instead of event_id

WIKI

----

  > fnordmetric

    > sending data 

      - _type, _time field mandatory

      - tcp, udp, redis, http

      - events containing user data (_session, _name)

      - _namespace

    > running fnordmetric

      - standalone

      - standalone w/ multiple workers

      - configuration options

  > event handlers

    - data, time, session etc methods

    - storing data in the session

    - end-of-session callback

  > gauges

    > timeseries gauge

      - calculate-option: count, sum, progressive_sum, avg

      - incr / incr_counter / incr_divisor

    > toplist gauge

    > distribution gauge

  > custom dashboards

    - here be dragons

  > examples

    - full_example.rb

  > hacking

    - here be dragons

IDEAS

-----

  > value correlation / scatter plot (2d) gauge

  > geo_distribution_gauge

  > correlation_gauge (2- or n-dimensional?)
