Hello, 

I'm working on adding performance instrumentation to the Parsoid codebase with statsd/node-txstatsd, and then visualizing the metrics via Grafana.  I'm at the stage where I'm looking to add the metrics' namespaces and schema to the WMF Grafana configs.   

It looks like WMF has Grafana working with Graphite/Carbon as a metrics database and ElasticSearch as the db database,  where can I find the production Carbon config files to input the settings for tmy metrics? 

Also, from my research WMF's carbon data retention schema is set to  '1m:1y, 10m:10y',  should I default to this as my retention schema? 

Note that the metrics are fired off anytime the Parsoid API is used so each datapoint doesn't necessarily represent a minute/second/etc of data.  

Thanks,

Christy
