If you are using Graphite & Diamond, graph-index will help you to build a wonderful index view !

• support regex search
• some pre-defined dashboard
• easily hack and a few lines of code

#Running

First:

git clone https://github.com/douban/graph-index.git
cd graph-index

edit the config.py to modify graphite_url, in our case it is http://graphite.intra.douban.com

then:

as a dependency, you should add a cron to update metrics like this: crontab -e, and put */5 * * * * python /path/to/update-metrics.py in it

finally:

now everything is ready, we can run it by:

./graph-index.py

graph-index also supports multi-workers with tools like gunicorn, In my case, I started it like this:

cd graph-index
/usr/bin/gunicorn -w 5 app:'default_app()' -b 0.0.0.0:8808

regex will draw a graph for each metric, for example: servers.[^\.]+.loadavg.01$

plugin:server:regex will display a graph with all metrics on hostname,for example: plugin:cpu:hostname

merge:regex will merge matched metrics in a single graph, for example: merge:.*loadavg\.01$

group\s*by\s*\-?\d+ will draw multiple graphs group by the \-?\d+-th field, for example: loadavg\.01$ groupby1
