Today, we launched a completely restructured and redesigned web site for our application performance monitoring and dynamic analysis framework Kieker: https://kieker-monitoring.net.
Any feedback on the new site is highly appreciated!

Kieker Days ’12 great success
The KoSSE-Symposium: Application Performance Management (Kieker Days 2012), which took place on November 29/30 in Kiel, has been a great success. 50 participants from academia and industry listened to 16 talks presented by researchers and practitioners. See the symposium web site, the KoSSE news post, and the DiWiSH photo gallery (in German) for details and photos.

Kieker 1.6 released
Today, we released version 1.6 of our Kieker framework for application performance monitoring and dynamic software analysis.
Major features
- Web-based UI for editing and running analysis projects (beta version)
- Adaptive monitoring: (De)activate monitoring on method signature level
at runtime based on signature patterns - Restructured and extended graph/visualization filters (trace coloring,
tooltips etc.) - Log rotation for file system writer
- Logging API: SLF4J support and logger selection via JVM argument
- Many new AspectJ-based probes for detailed event-based tracing
- Refactored realtime replayer based on new re-usable filters (realtime delay,
record logger etc.) - Java EE example: Now included in core binary release archive and based
on MyBatis JPetStore deployed to Jetty server - Definition of configuration properties and default values for analysis
plugins and repositories now annotation-based - Removed legacy control servlet (JMX interface should be used instead)
Quality
- Bug fixes
- Added a number of (JUnit) tests
See the release notes for details.
Kieker presented at ICPE 2012
At the 3rd ACM/SPEC International Conference on Performance Engineering (ICPE 2012) in Boston (MA, USA) we gave an invited poster/demo presentation of our Kieker framework.

- Added a number of (JUnit) tests
See the release notes for details.
Kieker accepted by SPEC RG
The SPEC Research Group, a group within the Standard Performance Evaluation Corporation (SPEC), has launched a repository of peer-reviewed tools for quantitative system evaluation and analysis. One of the first tools to pass the review process for this repository is our Kieker framework for application performance monitoring and dynamic software analysis.
- For details, please refer to the SPEC RG’s news post

- Enable/disable flushing of FS Writer
- Configurable shutdown delay for asynchronous writers
- Configurable Servlet parameters for periodic samplers
- Direct support for asynchronous analysis
- Java 5 no longer supported
- Refined Microbenchmark (+ SPEC macro-benchmark configuration)
