Doppler Benchmarking

Measure the performance of Doppler

Will measure messages per second, per minute, and per hour.

How it Works

This is a command line tool that will emit X amount of messages over Y units of time.

• run etcd etcd (assuming it is installed)
• run doppler bin/doppler (from loggregator root, make sure it's the latest binary')
• run dopplerbenchmark go run main.go in loggregator/src/tools/dopplerbenchmark

-writeRate	15000	Number of writes per second to send to doppler
-stopAfter	5m	How long to run the experiment for
