Throttle (Windows) 

PM> Install-Package Shuttle.Esb.Module.Throttle

INFO

This package currently makes use of Performance Counters which are only available on Windows. In due course these will be replace with Event Counters which are cross-platform. Pull Requests are welcome if you'd like to refactor in the meantime.

The Throttle module for Shuttle.Esb aborts pipeline processing when the CPU usage exceeds given percentage.

The module will attach the ThrottleObserver to the OnPipelineStarting event of all pipelines except the StartupPipeline and abort the pipeline if the SPU usage is exceeds the given percentage.

Registration / Activation

The required components may be registered by calling ComponentRegistryExtensions.RegisterThrottle(IComponentRegistry).

In order for the module to attach to the IPipelineFactory you would need to resolve it using IComponentResolver.Resolve<ThrottleModule>().
