[![Build Status](https://travis-ci.org/o/simmetrica.png?branch=master)](https://travis-ci.org/o/simmetrica)#Simmetrica (simple-metric-aggregator)Simmetrica is a lightweight framework for collecting and aggregating event metrics as timeseries data. It also comes with beautiful customizable dashboard for visualizing metrics with charts.![preview](https://raw.github.com/o/simmetrica/master/preview.png)###Dependencies* Python 2.6 or greater* Redis ServerMost of the current Linux distributions (also Mac OS X) comes with Python installed default. Simmetrica also uses `redis` for storing data, you can install `redis-server` with your favorite package manager.###Installinggit clone git://github.com/o/simmetrica.gitcd simmetricapip install -r requirements.txt**You need to run `redis-server` before pushing events and querying stored data.**###How to feed dataWe will use `push` method for notifying our events, it has 3 parameters:First parameter is `event`, which is canonical name of your input data. You'll use this name when querying data and configuring dashboard. Second is `increment`, this optional argument is useful for overriding event count for submitting multiple events in a single operation. Last parameter `now` is defaults to current Unix timestamp, lets you to specify when event occurs.###How to query dataTo aggreagate stored data, we will use `query` method, it has 4 parameters:First one is `event`, as you guessed, we already used this value for feeding our data. `start` and `end` parameters take Unix timestamp for specifying interval of time-series. This parameters are mandatory. Last parameter `resolution` is used for defining the resolution / granularity of data. This is an optional parameter and it defaults to `5min` (five minutes). Possible values are `min`, `5min`, `15min`, `hour`, `day`, `week`, `month` and `year`.###Using library#####Feeding>>> from simmetrica import Simmetrica>>> simmetrica = Simmetrica()>>> simmetrica.push('add-cart-action')[1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L]Overriding default parameters:>>> simmetrica.push('nginx-connections-received-5min', increment=5, now=1364298120)#####Querying>>> start = simmetrica.get_current_timestamp() - 600>>> end = simmetrica.get_current_timestamp()>>> results = simmetrica.query('add-cart-action', start, end, 'min')>>> for time, val in results:...     print time, val...1364297940 01364298000 01364298060 01364298120 01364298180 01364298240 01364298300 01364298360 01364298420 01364298480 11364298540 2###Using command-line#####Feeding➜ python cli.py push add-cart-actionokOverriding default parameters:➜ python cli.py push nginx-connections-received-5min --increment=5 --now=1364298120#####Querying➜ python cli.py query add-cart-action 1364297990 1364298608 --resolution=min1364297940 01364298000 01364298060 01364298120 01364298180 01364298240 01364298300 01364298360 01364298420 01364298480 11364298540 2Beautify with [spark](http://zachholman.com/spark/)➜ python cli.py query add-cart-action 1364297990 1364298608 --resolution=min | awk '{print $2}' | spark▁▁▁▁▁▁▁▁▁▄█###Using REST#####FeedingAfter running `app.py`➜ curl 127.0.0.1:5000/push/add-cart-actionokOverriding default parameters:➜ curl 127.0.0.1:5000/push/nginx-connections-received-5min?increment=5&now=1364298120#####Querying➜ curl "127.0.0.1:5000/query/add-cart-action/1364297990/1364298608?resolution=min" | python -mjson.tool{"1364297940": 0,"1364298000": 0,"1364298060": 0,"1364298120": 0,"1364298180": 0,"1364298240": 0,"1364298300": 0,"1364298360": 0,"1364298420": 0,"1364298480": "1","1364298540": "2"}###Overriding redis connection parametersAs default Simmetrica connects to Redis on `127.0.0.1:6379` with database `0`.#####In library>>> from simmetrica import Simmetrica>>> simmetrica = Simmetrica(host='192.168.5.30', port=7000, db=16, password=qwerty)#####In commandline and REST`redis_host`, `redis_port`, `redis_db` and `redis_password` parameters can be passed as commandline arguments in `app.py` and `cli.py`.➜ python cli.py ... --redis_host=192.168.5.30 --redis_port=7000 --redis_db=16 --redis_password=qwerty###Dashboard#####Running web application➜ python app.py* Running on http://127.0.0.1:5000/Now, you can see your shiny dashboard with pointing your browser to `http://127.0.0.1:5000/`.Optionally a custom config file can be specified with the `--config` flag.➜ python app.py --config myConfig.yml#####Configuring dashboard blocksDashboard is configured with `config.yml` file, this file has a yaml list called `graphs`.
