ExpressionTracer
During the first week of May, I got engaged with a customer that needed help with adding more detailed performance metrics of NordicEdge Certificate Server, which is a Tomcat hosted SiteMinder add-on.
The end-result was new metrics providing live-feeds of the
- Certificate status count, i.e., Valid vs. Revoked
- Certificate issuer count
- New certificates count, for some aggregated periodes
- and more…
One of my tools used, was an extension I wrote several years ago, which I also had to brush up and amend with some additional features. The extension is called ExpressionTracer and allows one to inject (almost) arbitrary Java expressions on the target instrumented object.
I plan to publish this tracer type on my site, anytime soon I have some spare time left. If you are in hurry, don’t hesitate to drop me an email.
Introscope extensions
Back in January 2005 I joined an existing San Francisco based company named Wily Technology. This was the beginning of a few years of hectic traveling, hacking and trouble-shooting. Meaning I traveled around in Europe, mostly UK and Germany, working at customer sites (some very large banks) helping them with performance and problem analysis of large Java EE systems.
The tool Wily provided was named Introscope and was the first tool in its market segment when it started in 1999 and was the market leader all the time. One of my key missions was developing (hacking) numerous extensions for Introscope based on customer requests or my own observation of what I though the customers (or we professional consultants) needed.
As part of my re-launch of Ribomation as an independent consultant I have partnered with CA-Wily to partly do what I once did for Wily. Wily Technology was later acquired by CA. During this spring I have helped a governmental institution in Northen Sweden with a roll-out of Introscope as a monitoring solution for their Java systems.
One specific task was to enable alert integration with Tivoli. Back at the Wily era, I wrote an alert action extension for OpenView integration. In this case, I decided to make the extension more general and versatile, ant not tied to any specific SMC tool. The end-result is now released as open source and can be found here: SMC AlertAction.
Intro to Wily Introscope
I gave an internal speech, 8 May 2008, regarding what I did in the past, regarding application performance management using Wily Introscope, for current collegeuages.
