Visual Bus Monitor
For the past few weeks, I've been focusing on seeing how we can improve the development / debugging experience with ErraiBus. The biggest component of this, is our new Swing-based ErraiBus Monitor application.
It's really straight-forward to get up and running.
You simply add it as a runtime dependency, and bootstrap GWT Development Mode with the -Derrai.tools.bus_monitor_attach=true VM flag, and this magical UI should automatically appear as ErraiBus bootstraps.
When the monitor is activated, it attaches probes in into the bus and records all activity accordingly. You can drill down into individual services and examine individual messages that have been received to debug any mysterious problems that arise.
There will be more details to come as I firm up the tool, but I thought I'd share my progress with the community since Heiko says I don't blog enough :)
