About the ADF Performance Monitor

The first version of the ADF Performance Monitor was created by Frank Houweling and released in 2009. This was first an ADF 10g version; this version consisted of printing performance metrics in JDevelopers console log only (what methods, operations and queries were executed, when and how often). The urgent need of performance visibility came back every time in somewhat all Oracle ADF projects; nearly all ADF applications had performance problems in some way and extreme difficulty in identifying these bottlenecks.

One year later (2010) the second version was released including saving metrics to the database. In 2011 a dashboard application was added that visually reported the performance metrics saved in the database. Last years the monitor has been extensively improved and extended with many new and advanced features.

Over last years the ADF Performance Monitor has been implemented in more than 50 Oracle ADF business production applications – in more than 25 countries in the world; for example in the Netherlands, Germany, Belgium, United Kingdom, France, Spain, Canada, United States, Switzerland, Austria, Romania, Poland, Libanon, Sultanate of Oman, India, China, Australia, e.g.
