Subject Re: [ANN] hawtio: a new lightweight HTML5 console for Apache Camel, ActiveMQ, JMX, OSGi & Fuse Fabric
Date Fri, 25 Jan 2013 11:32:07 GMT
it looks really nice…I just give it a try, trying to install it in Karaf,
where is my Camel project running, but after ~50 minut I wasn't succesfull.
I was trying to utilize Fuse features.xml, to install hawtio, but that
wasn't probably good idea :)
I'll come back to it later, but if there is a easy way how to install
hawtio as OSGi bundle into Apache Karaf, let me know, please.
I'm still new in those things, so most probably I just did something wrong,
or over-complicated :)

> A quick summary of the current features for camel folks:
> * If you have any camel contexts running in a JVM when hawtio starts
> up it adds an Integration tab which shows all the camel contexts
> running.
> * You can start/stop/suspend/resume the context and its routes; then
> look at all the metrics for routes/endpoints/processors. The Charts
> tab lets you visualise the real time metrics.
> * You can create new endpoints; browse endpoints which are browsable &
> send messages to endpoints (with syntax editing support for JSON / XML
> / YAML / properties)
> * You can visualise all the camel routes or a specific camel route for
> a context in the Diagram tab and see real time metrics of how many
> messages are passing through each step on the diagram. e.g.
> * Clicking on a Route allows you to Trace it; when tracing if you send
> a message into a route then it captures a copy of the message at each
> point through the route. So you can step through (scroll/click through
> the table) a route and see the message contents and how the message
> flows through the EIPs - highlighting where on the diagram each
> message is. This is very handy for figuring out why your route doesn't
> work :) Spot where the heading disappears! Or see why the CBR doesn't
> go where you expected.
> In general most of the runtime features of the open source Fuse IDE
> eclipse tooling are now supported in the camel hawtio plugin; so
> available in a web browser.

> So if you're vaguely interested in web consoles for Apache Camel I

> Feedback appreciated! Its hawt, but stay cool! ;)
