Ax\_Metrics - "BI Glue" Business Intelligence middleware Python library
=======================================================================
Overview
--------
Ax\_Metrics is an Business Intelligence (BI) open source Python
middleware library facilitating aggregation of metrics and KPIs from any
source and custom reporting for humans or other APIs.
Target Problem
~~~~~~~~~~~~~~
1. You have multiple systems of all scales generating metrics and logs.
2. Your centralized or distributed Data Warehouse (DW) collects this
data, indexes it by time, and makes it available.
3. You want fast, friendly, pretty, clean access to KPIs that will help
you grow your business.
4. Most solutions are incompatible, insecure, expensive, or far too
complex.
5. You have technical knowledge at least on the level of understanding
HTML, XML, YAML, etc.
The Solution: Ax\_Metrics
~~~~~~~~~~~~~~~~~~~~~~~~~
Ax\_Metrics is a library to empower BI initiatives. The *components
described below* work together to comprise a powerful hub for connecting
data, processing it, and getting it where it needs to be.
MDefL
^^^^^
Ax\_Metrics **Metrics Definition Language** - Model your metrics and
KPIs (Key Performance Indicators) with just a few lines of this
YAML-based definition language, defining where and how they're located,
indexed, and typed. *Some example metric sets ("MetSets") used by
automated tests: metset1.yml and metset-http.yml.*
EMFetch
^^^^^^^
Ax\_Metrics **Extensible Metrics Fetch** - The EMFetch engine provides
low level access to raw time-indexed metrics data for the rest of
Ax\_Metrics. Metrics described by your MDefL reference the EMFetch
plugin used to access them. *Plugins like emf\_http are available for
use, or extend them with your own Python code to easily integrate with
any custom data source.*
MQL
^^^
Ax\_Metrics **Metrics Query Language** - Create MQL queries in this
YAML-based query language to slice, dice, time shift, forecast, smooth,
compare, and format your data into reports for humans or other APIs. *An
example query used by automated tests can be seen in mqe-query2.yml,
while an even more complex query set containing multiple pre-defined
queries can be seen in queryset2.yml.*
MQEngine
^^^^^^^^
Ax\_Metrics **Metrics Query Engine** - Embed MQEngine in your BI flow or
place it behind a web server to process MQL queries on demand, within
any security/authorization layer and web app you already use. MQEngine
is the Ax\_Metrics core that processes any query you throw at it and
yields data sets.
EROut
^^^^^
Ax\_Metrics **Extensible Report Outputter** - ERout outputters present
data reports from MQEngine in many formats, for humans or further API
consumption. *Plugins like csv and geckoboard\_numsec (for your 60" LCD
dashboard powered by `Geckoboard <http://www.geckoboard.com/>`__) are
available for use, or extend them with your own Python code to easily
integrate with other any data consumer, human or machine.*
Servant
^^^^^^^
Ax\_Metrics **Servant** - The high layer Servant is available to wrap
everything up in a convenient package. This is the recommended
integration point for most Ax\_Metrics use: *build a Servant around a
ServantConfig object, then construct ServantRequest objects and feed
them to the Servant. This is also the best place to start if you want to
dig into the Ax\_Metrics code itself, as it leads to all other pieces.
See test\_servant.py for test code that invokes Servant.*
Ax\_Metrics is *NOT...*
~~~~~~~~~~~~~~~~~~~~~~~
NOT a web service
^^^^^^^^^^^^^^^^^
Ax\_Metrics does NOT include any web services or APIs that run in the
background or require hosting or IT/DevOps support. It is a software
library to utilize and integrate as you see fit. (Though it does include
some helper routines to make integrating with your own web environment
easier.)
NO persistence DW capabilities
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Ax\_Metrics fetches data dynamically and generates reports on demand.
Some data may be cached for performance purposes, but this cache should
be considered a volatile implementation detail only. Your data is
assumed to already persist in a queryable form.
NOT a turnkey solution
^^^^^^^^^^^^^^^^^^^^^^
Ax\_Metrics requires custom integration into DW sources, custom
definition of metrics and reports, and often customization of output
formats. It is a powerful and time-saving support library for use in BI
data visualization projects, but it is not a magic bullet.
NOT a visualizer or chart generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Ax\_Metrics is designed to be used *with* visualization and charting (or
other) output systems. It is a middleware library that helps fetch,
analyze, and wrangle your data into a format ready to be visualized.
"Can't I can just use SQL instead?"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If your data already exists in a relational database, then you already
have direct access to it. You can write SQL queries to generate various
reports, but as you analyze more deeply, your queries will become
complex, slow, and eventually impossible, requiring additional
processing outside of your DB.
Review various 3rd party charting packages and you'll see mostly
simplistic examples like "sales per month by region" which are easily
queryable from raw data. That's a great start, but it will only get your
BI efforts so far.
Ax\_Metrics treats raw time series data (such as might be stored and
queryable in a relational DB) as the *input* to deeper BI analysis. Read
on to see some examples of the types of reports it can produce. And in
addition to higher level analysis, Ax\_Metrics can also provide ties in
to multiple DW sources as well as the foundation for your metrics
definitions and queries, all written in the high-level user-friendly
languages MDefL and MQL, allowing you to focus on your own personal
business metrics instead of reinventing the wheel.
In summary, you can use SQL (or anything else) to query raw time series
data, but when you layer Ax\_Metrics on top of that, you add
intelligence and move your data closer to more powerful and useful
visualization and analysis.
Examples of Use
---------------
Example Metrics
~~~~~~~~~~~~~~~
Anything that can be measured numerically over some period of time is a
valid metric.
Examples:
- new trials
- new sales
- new revenue
- invites sent
- invites read
- invites accepted
- web visitors
- web requests
- expenses
- app server errors
Example Reports
~~~~~~~~~~~~~~~
Once your metrics are defined and the EMFetch plugins integrated with
your data sources, a wide variety of reports can be easily built to view
that data. Much of the power of Ax\_Metrics arises out of the rich time
frame model and query language.
Examples:
- amount per 5 minutes for the last 6 hours
- daily amount over past 30 days, compared to same 30 day period 1 year
ago *(e.g. visualized as multi-series (2) line chart)*
- amount in current calendar week to date, compared to previous week
and same week 1 year ago *(e.g. as multi-series (3) line chart)*
- amount in calendar month to date, compared to forecast amount *(e.g.
visualized as bullet chart)*
- amount in last completed calendar quarter, measured weekly with 30
day smoothing, compared to forecast amount, previous quarter, and
same quarter last 2 years *(e.g. visualized as multi-series (5) line
chart)*

Genesis
~~~~~~~
This project was inspired in late 2014 by a need to effectively digest
and visualize large amounts of business metrics -- to measure, guide,
challenge, and inspire. The source code is cleaned and released under a
liberal license in the hopes that others will find it useful and build
on it.
