Engflow has metrics for remote execution, we need a script which can extract this data.

Talking with engflow, they have[ a grpc API|https://github.com/EngFlow/engflowapis] (example java client) they expose for collecting build events. This is not ideal as we would need to write and maintain a build event collection service ourselves, store the data somewhere, and then finally write something to extract the data into the build metrics and developer workflow metrics tools. If this is the case we may need to break this ticket down into smaller chunks for creation of such system.

 
Engflow has an analytics page which appears it would require collecting and storing the build events, so hopefully there is a way to access that data instead of writing our own thing.
