Hi, 
In our system, we use monitor by TICK stack (include: Telegraf  for collect metric, InfluxDB for storage metric, Chronograf for visualize and Kapacitor alarming), which is popular monitor solution.
We hope can integrate vitrage in, so we decide to write kapacitor datasource contribute for vitrage. 
The work is almost done , you can review in:

So i send this mail hope for more review, ideal,... Appreciate it.
also ask: have any step i miss in pipeline of contribute datasource vitrage? like create blueprints, vitrage-spec,vv.. Should i do it?
