From the ReactiveFramework to StreamInsight and Back

In my last post I showed how to send StreamInsight output streams to a UI via the ReactiveFramework . Here’s we’ll do the reverse, by sending an RX stream into a CEP stream. Instead of a partial example, I’ll use an end to end example showing simulated...

Routing StreamInsight output streams to a UI

One compelling feature of StreamInsight is it’s in-process hosting model. In addition to reducing the complexity of server side installs, it’s now possible to have a  CEP engine in the client UI. The simplest way of getting CEP streams onto the UI...

Exploring the Reactive Framework part II

Talk around the water cooler is that it might be possible to use the Reactive Framework for some lightweight CEP. I’ll correct some of the (big) mistakes from my last post and build up a “jumping” window extension method for IObservable s.   In my...

CPU Monitoring and Alerting via Performance counters, Coral8, and PowerShell

The PowerShell team has a short post on using V2 cmdlets to Monitor performance counters. Building on that, and the prior work with the PoShAdapter, here’s a sample with Coral8 and PowerShell to alert you via SMS when the rolling 30 seconds average CPU...

Using Coral8 and PowerShell to receive eventing data

I’ve updated the PowerShell Coral8 adapter so it can be used to receive input. Rather than demonstrate input from a database or an RSS stream, both of which can are supported by the native Coral8 adapters, I have a demo with WMI events. In this case allowing...

In-process PowerShell adapter for Coral8

A few days ago a thought crept into my head; wouldn’t it be nice if I could have a Coral8 in-process adapter to run PowerShell code? If it worked it could potentially be a “universal” adapter, limiting the need for custom one-off adapters. Coral8, out...
