Simulator

Start a simulation with load balancer and event stream.

How to run

Run like go run *.go <url> [<event_file>] [<output_file>]. Default values for event_file and output_file are data/events.csv and logs/YYYY-MM-DD/HH:ii:ss.log respectively.

Notes that default simulation file(data/events.csv) has a lot of events, so you may need multiple worker nodes. We recommand at least 8 worker nodes with 4 vCPU for each node (e.g. EC2 m4.xlarge).

$ go run *.go http://localhost:8111
$ go run *.go http://localhost:8111 data/events_small.csv
$ go run *.go http://localhost:8111 data/events_small.csv output.log

If you want to generate your own event stream, you can use generate_event_streams.py on utils. The CSV file only contains FunctionName, StartTime pairs, so you can easily create another simple simulation scenario.
