Change subject: core: Monitor action executions with hystrix ...................................................................... core: Monitor action executions with hystrix Wrap all action executions into synchronous hystrix commands. This allows easy live monitoring of all actions. The hystrix event stream servlet is listening on http://<host>/ovirt-engine/services/hystrix.stream Hystrix monitoring is disabled by default. It first needs to be enabled with engine-setup -s HystrixMonitoringEnabled=true and a restart of the engine is required. Afterwards it can be controlled with JMX MXBean methods: HystrixCommandController#monitor*('true') Also more fine grained control on which commands should be monitored is possible in the JMX bean. To get a nice monitoring dashboard use hystrix-dashboard and point it to the hystrix stream url. The url is protected with basic auth, like the rest api. Hystrix dashboard requires the basic auth parameters to be provided in encoded form. If your credentials are admin@internal:engine you have to provide 'Basic YWRtaW5AaW50ZXJuYWw6ZW5naW5l' Benefits are: * Easier verification while implementing features, because failing commands are immediately visible on the dashboard. * Easier verification for QA because of the same reason. * Immediate insights in what is going on inside the application for our solution architects and support when customers are facing problems.
