canaryd is an aggregator for measurements taken by sensord. It ingests metrics via UDP and stores a small window of them in a Redis instance. Those measurements are then made available via a simple HTTP API.

$ go get github.com/canaryio/canaryd
$ cd $GOPATH/src/github.com/canaryio/canaryd
$ godep get
$ godep go build

canaryd is configured via the environment. The following values are allowed:

• PORT - port the HTTP and UDP servers should bind to, defaulting to '5000'
• REDIS_URL - URL for the redis backend, defaults to redis://localhost:6379

canaryd allows metrics to be recorded to Librato. You can configure with the following environment variables:

• LIBRATO_EMAIL - email address of your librato account
• LIBRATO_TOKEN - token for your Librato account
