Surely by now you have tasted the goodness that is tables.  No?  Stop now and go read up on the table command.  No, really, right now!  I’ll wait… OK, now that you are a tables expert, it’s clear to you that this is very powerful, but as I’m sure you read in the fine print, there’s no way to get to the table data outside of tmm.  That means no shell access, no icontrol access, no nada.  But, as is often the case, iRules to the rescue!    The REST interf...
Last week I talked about generating a heat map 100% via iRules, thanks to the geolocation magic in LTM systems, and the good people over at Google letting us use their charting API. This was an outstanding way to visualize the the traffic coming to your application. For those interested in metrics it provides a great way to see this data in a visually pleasing manner.  That said, it was pretty basic.  All it showed was the United States which, for anyone that has used the internet much...

Ever wondered how you could bring the power of iControl to your browser? A little AJAX (Asynchronous Javascript and XML) magic and you'll be well on your way to building a real-time web-based management or monitoring application for your BIG-IP using iControl. What's probably going to sound strange is that the AJAX part of the web application is the easy part. That's right, AJAX is easy. That's because security restrictions on the XMLHttpRequest object - the heart of AJAX - mean that you c...
By Lori  MacVittie In the increasingly buzzword compliant world of SOA and Web 2.0 it is inevitable that you have, or will, come across three of the industries’ favorite terms: composites, mashups, and processes. These terms represent concepts that while similar actually describe very different uses of services. The distinctions between the three are subtle and in many cases it makes almost no sense to differentiate between them. But one of the goals of SOA is to provide a common ...
Introduction Any large development library has some choices to make about implementation, and iControl is no exception. A library is designed to give others access to routines that you have written (in our case, BIG-IP interfaces), and when the public-facing interfaces are defined, the designers have to try and foresee how the majority of users will want to use the library.  With iControl for BIG-IP, the design was approached as what I call “Building Block Minimalist”. That’s where you bu...
kSOAP is a lightweight access library for web services. Designed with hand-held devices in mind, it's light and easy to use, but documentation and samples for the project is lacking. YOu can download the kSOAP libraries and JavaDoc documentation here. There are not a ton of solid examples out their for using KSOAP to access web services, in fact, only one page on a wiki has good solid examples, and they're not well explained. Since we're using kSOAP to access BIG-IP from cell phones via JavaSE...
Configuring the Web Accelerator Module Using the WebAccelerator Module should be viewed as adding a complex profile to an HTTP/S Virtual Server.  This profile is added by creating a WebAccelerator enabled class and assigning it as a resource to a Virtual Server with an HTTP profile. Expand the WebAccelerator portion of the UI and click on the plus sign of the Classes section to create a new WebAccelerator enabled class. Just give it an appropriate name, accept all the other ...
