The 15th Symposium on Software Performance (SSP ’24) was held from November 5 to 7, 2024 in Linz, Austria. It was the first edition of the SSP series that took place outside Germany.

Every year, the SSP brings together researchers and practitioners interested in software performance and related quality attributes. The scope of SSP spans measurement, modeling, benchmark design, and run-time management.

On September 22, 2024, we released version 2.0.0 of our Kieker framework for application performance monitoring and dynamic software analysis.

We dedicate this major release to our dearly missed friend and colleague André van Hoorn who passed away during the development of this release. He was one of the founding developers of Kieker and head maintainer for many years. He supported the efforts to transform Kieker into a modern framework and tool set for monitoring, performance analysis and architecture recovery. Therefore, we dedicate this release to him.

We release all Kieker libraries via Maven repositories. Information on repositories and downloads are available at https://kieker-monitoring.net/download/ and the source code release is available at https://github.com/kieker-monitoring/kieker/releases/tag/2.0.0.

We started the development of instrumenting Python last year and have developed monitoring probes for Python and two weaving approaches. They will be presented (hopefully) at the Symposium for Software Performance. However, the tooling is already available and can be found on GitHub. Currently, we are integrating new features, cleanup the code and write documentation for end users. All these artifacts will become available in the general Kieker documentation.

Kieker now provides monitoring probes for C, Fortran and any other language supported by the GNU Compiler Collection or the Intel compilers including ifort. The code is currently available on GitHub. In the near future, we will provide Debian/Ubuntu packages for the library and examples.

We developed in iObserve support to monitor user behavior, create user behavior models and cluster them. These features will now be integrated in the the Kieker main repository to ease their use and make them available for a larger audience.

The behavior model monitoring provides additional entry level probes that record calls from web browsers or other services interacting with the monitored service.

The 12th Symposium on Software Performance (SSP ’21), was held from November 8 to 10, 2021 in Leipzig, Germany. Luckily, the SSP could take place as a physical meeting despite the Covid-related circumstances.

Every year, the SSP brings together researchers and practitioners interested in software performance and related quality attributes. The scope of SSP spans measurement, modeling, benchmark design, and run-time management.

We are happy to announce that we released our Kieker trace diagnosis tool in Version 5.2.0. A must-have tool to analyze and filter your Kieker monitoring logs! Apart from some internal improvements, we also fixed some bugs and are now using and supporting Kieker 1.15. The full changelog can be found at https://github.com/kieker-monitoring/kieker-trace-diagnosis-ui/blob/5.2.0/CHANGELOG. Download the latest release at https://github.com/kieker-monitoring/kieker-trace-diagnosis-ui/releases.

On October 8, 2021, we released version 1.15 of our Kieker framework for application performance monitoring and dynamic software analysis. As usual, the release is available for download at https://kieker-monitoring.net/download/.

The 12th Symposium on Software Performance (SSP 2021) will take place in Leipzig, Germany on November 9-10, 2021. It will be a joint meeting of the Descartes, Kieker, and Palladio research groups.

In addition to invited talks from practitioners and researchers, we welcome contributions from academic, scientific, or industrial contexts in the field of software performance, including but not limited to approaches employing Descartes, Kieker, and/or Palladio.

We solicit technical papers (5-6 pages, CEUR-WS format) and extended abstracts for industry or experience talks (maximum 700 words).

The 11th Symposium on Software Performance (SSP ’20), was held as an online event from November 12 to 13, 2020. Every year, the SSP brings together researchers and practitioners interested in software performance and related quality attributes. The scope of SSP spans measurement, modeling, benchmark design, and run-time management. SSP 2020 was planned to take place in Leipzig, Germany. Unfortunately, due to the Covid-related circumstances, a physical meeting was not possible.
