-------------------------------------------------------------------------------- 1 | # Graph Index 2 | 3 | If you are using [Graphite](https://github.com/graphite-project/graphite-web) & [Diamond](https://github.com/BrightcoveOS/Diamond), graph-index will help you to build a wonderful index view ! 4 | 5 | * support regex search 6 | * some pre-defined dashboard 7 | * easily hack and a few lines of code 8 | 9 | # Screenshot 10 | 11 | ![Screenshot](https://raw.github.com/douban/graph-index/master/static/image/graph-index.png) 12 | ![Screenshot](https://raw.github.com/douban/graph-index/master/static/image/graph-index-server.png) 13 | ![Screenshot](https://raw.github.com/douban/graph-index/master/static/image/graph-index-plugin.png) 14 | 15 | # Running 16 | 17 | First: 18 | 19 | ```shell 20 | git clone https://github.com/douban/graph-index.git 21 | cd graph-index 22 | ``` 23 | 24 | edit the config.py to modify `graphite_url`, in our case it is `http://graphite.intra.douban.com` 25 | 26 | then: 27 | 28 | 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 29 | 30 | 31 | finally: 32 | 33 | now everything is ready, we can run it by: 34 | 35 | ``` 36 | ./graph-index.py 37 | ``` 38 | 39 | graph-index also supports multi-workers with tools like gunicorn, In my case, I started it like this: 40 | 41 | ``` 42 | cd graph-index 43 | /usr/bin/gunicorn -w 5 app:'default_app()' -b 0.0.0.0:8808 44 | ``` 45 | 46 | # Grammar 47 | 48 | `regex` will draw a graph for each metric, for example: `servers.[^\.]+.loadavg.01$` 49 | 50 | `plugin:server:regex` will display a graph with all metrics on `hostname`,for example: `plugin:cpu:hostname` 51 | 52 | `merge:regex` will merge matched metrics in a single graph, for example: `merge:.*loadavg\.01$` 53 | 54 | `group\s*by\s*\-?\d+` will draw multiple graphs group by the `\-?\d+`-th field, for example: `loadavg\.01$ groupby1` 55 | 56 |
