Metron Benchmarking

Measure the performance of Metron

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

Note there is a script loss_report.sh which does the following housekeeping for you

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 metron bin/metron -config=src/tools/metronbenchmark (from loggregator root, make sure it's the latest binary')
• run metronbenchmark go run main.go in loggregator/src/tools/metronbenchmark

If you get in a bad state you might need to delete the doppler keys from etcd:

curl -X DELETE http://localhost:4001/v2/keys/doppler?recursive=true
