Integrating AJAX with the JMX Notification Framework

Opposite Ends of the Systems Management Stack

Some users have found that IE will cache the response from the AJAX request. This could be due to browser/page settings, but a forced workaround is to timestamp the URL:

var urlstr = "./admin?reqId=0&ts=" + new Date().getTimeStamp();

To XML or Not to XML
Not to XML. Some AJAX designers happily dispense with XML and send the response as plain text:


This clearly depends on your client-side requirement and how loosely coupled the client is from the data required. A simple text response would suffice for a text alert. However, the advantage of the XML model for this article is that the response data can be elaborated further to refine both the status and status-related data. This article demonstrates how you'd parse a more complicated response that the client may have to code to accept.

AJAX presents architectural opportunities that shouldn't be overshadowed by the rich-client frenzy. This article has leveraged the architectural advantage AJAX can provide while addressing the technical requirements for both capacity and security that more exotic uses of this technology will demand.

The standardization of container runtimes and images has sparked the creation of an almost overwhelming number of new open source projects that build on and otherwise work with these specifications. Of course, there's Kubernetes, which orchestrates and manages collections of containers. It was one of the first and best-known examples of projects that make containers truly useful for production use. However, more recently, the container ecosystem has truly exploded. A service mesh like Istio addr...
Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.
Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
Business professionals no longer wonder if they'll migrate to the cloud; it's now a matter of when.
