Traffic Stats is a utility written in Go that is used to acquire and store statistics about CDNs controlled by Traffic Control. Traffic Stats mines metrics from the Traffic Monitor APIs and stores the data in InfluxDB. Data is typically stored in InfluxDB on a short-term basis (30 days or less) and is used to drive graphs created by Grafana which are linked from Traffic Ops. Traffic Stats also calculates daily statistics from InfluxDb and stores them in the Traffic Ops database.

go mod vendor -vto get the dependencies
Once the tests pass, run
go installto build and install the Traffic Ops client package. This makes it accessible to Traffic Stats.
