README

        
metronome

=========

Mini-graphite that uses client-side java script to render graphs w/o depending on graphite.

'metronome' implements the carbon protocol, so anything that can feed Graphite can feed metronome.

We also accept submissions via POST:

For example, to submit RX bytes for eth0:

    while true;

    do

        VAL=$(ip -s link ls eth0 | grep RX -A 1 | tail -1 | awk '{print $1}')

        wget -q --post-data="" "http://127.0.0.1:8000/?do=store&name=rxbytes&timestamp=$(date +%s)&value=$VAL" -O /dev/null

        sleep 1

    done

To retrieve data:

    $ wget http://127.0.0.1:8000/?do=retrieve&name=rxbytes&begin=0&end=$(date +%s)&callback=jsonp

This delivers a JSONP callback with your values in there.

To view, try html/index.html

Installing

==========

Dependencies include a recent g++ (4.7+), Boost and libeigen.

Installing Eigen

----------------

Either install `libeigen3-dev` (Debian, Ubuntu), `eigen3-devel` (Fedora, EPEL).

To install it manually:

    $ wget http://bitbucket.org/eigen/eigen/get/3.2.1.tar.bz2

    $ tar xf 3.2.1.tar.bz2

Compiling

=========

    $ ./bootstrap

    $ ./configure

    $ make

If you installed libeigen manually, use `./configure --with-eigen=/path/to/eigen`

Running

=======

    $ mkdir stats

    $ ./metronome --stats-directory=./stats

Next, host the 'html/' directory somewhere on a webserver, and edit 'html/local.js' so

it knows the Webserver IP address of metronome (port 8000 on :: by default).

Thanks to

=========

Aki Tuomi for the excellent [yahttp](https://github.com/cmouse/yahttp), 

[Rickshaw](http://code.shutterstock.com/rickshaw/) for the graphs. [Eigen](http://eigen.tuxfamily.org) for the math. And a cast of thousands for C++2011.

status

======

"Toy" for now - stores all data in flat files, which we read in their entirety to 

replay data.

But, starting to look nice.
