Introducing PostgreSQL Dashboard

## A real-time monitoring screen based on Dashing and Sinatra

PostgreSQL Dashboard is simple monitoring tool that provides a live
activity report of a PostgreSQL instance.

Here's a screenshot :

It is designed to be displayed on a large screen in a monitoring room or
an open space office. The current dashboard is currently composed of 5
widgets :

* General Info : Version, number of host databases, etc.
* Hit Ratio : The % of data found in cache
* Buffers : The number of new buffers allocated
* Queries : The number of active queries currently running
* Twitter : A glimpse of the #PostgreSQL feed

## Extensibility

Adding a new widget should be fairly easy. This tool is designed so that
you can write a custom widget to display the stats you find relevant or
a dynamic graph on some "business logic" valuation.

The layout is also entirely flexible. You can easily drag'n'drop any
widget to put it wherever you want on the screen. And HTML code of the
dashboard can be modified for specific needs, such as specific screen
dimensions.

## Links & Credits

Some parts of this tool are based on the work done on other PostgreSQL
tools, especially [pgstats](https://github.com/gleu/pgstats) and
[pgcluu](http://pgcluu.darold.net/)

PostgreSQL Dashboard is an open project distributed under the PostgreSQL
license. Any contribution to build a better tool is welcome. You just
have to send your ideas, features requests or patches using the GitHub
tools.
