Setup

$ sudo apt install golang
$ export GOPATH="$HOME/go"
$ bash requirements.txt
$ go run server.go
2018/08/09 17:02:31 Starting HTTP listener on 8080
2018/08/09 17:02:31 Starting TCP listener on 1337

Connect your browser on port 8080 and the AllScale runtime to TCP port 1337. Both ports are configurable.

$ go run server.go --help
Usage of /tmp/go-build252098734/command-line-arguments/_obj/exe/server:
  -http-port int
        port for the HTTP listener (default 8080)
  -msg-gen
        generate random messages
  -msg-gen-interval int
        message generator interval [ms] (default 1000)
  -tcp-port int
        port for the TCP listener (default 1337)

A random message generator is provided and can be activated with -msg-gen.

Message Format

All messages sent between this server and the AllScale runtime are length prefixed.

Every message received from the runtime will be forwarded to all websocket instances -- and vice versa.

See send_test_message.py and receive_test_message for a very basic example.

The rough specification for status updates can be found in runtime_state_dump_example.json.

The random message generator can be used simultaneously.

Performance

Having that many charts rendering in the browser can be quite performance intensive (yeay Javascript). When having the dashboard open, open the browser console and use setRefreshInterval(ms) to adjust the update rate.
