Fairly regularly I give a training on Weblogic Tuning and Troubleshooting, where I talk about JVMs, Garbage Collections, and some subsystems of Weblogic, JMS and JDBC for instance, and how to tune and troubleshoot them.
One of the larger parts of the training is the Weblogic Diagnostic Framework. I find it quite interesting, but also pretty complex. And maybe therefor hardly used in the every day Weblogic administration. And that might be a pity, because it can be quite powerfull. You can find the use of it in Fusion Middleware, with preconfigured policies and actions. But I guess that other tooling on Weblogic diagnostics and monitoring, like WLSDM also rely on it (although I don’t know for sure).
Configuring WLDF might be quite hard, and during the last run of the training, I figured that it might help to turn the solution of the workshop into a script. At least to show what you’re doing when executing the labs. But, certainly also to show how you can put your configurations into a script that you can extend and reuse over different environments.
This week I got a question on the Oracle community, To be notify of les warning Logs, that made me remember this script. Maybe it’s not exactly the answer, but I think at least it can be a starting point. And I realized that I did not write about it yet. Read the complete article here.
