Kieker 1.14 released

On May 12, 2020, we released version 1.14 of our Kieker framework for application performance monitoring and dynamic software analysis. As usual, the release is available for download at

  • New features (selection)
    • Integration of a novel pipes-and-filter framework and filters in
      Kieker.Analysis based on TeeTime (
      version 3.0). Additional documentation will be added. Currently, the
      TeeTime-based framework and filters exist in parallel to the
      existing infrastructure. The long-term plan is that the
      TeeTime-based infrastructure replaces the existing one.
    • New file system writer to replace the existing ones in the next
      Kieker release
    • Generic file writer supporting different compression types
    • Monitoring support for Spring-based REST communication with AspectJ
    • Support for enums in IRL
    • Support for additional compression algorithms in the file writers
      and readers
    • New TeeTime reader stages with a common interface to use them in
    • Introduced new Kieker tool framework covering command line and
      configurations file evaluation (see Writing Tools and Services)
    • Added monitoring of database calls (including the SQL statement)
    • Introduced new data bridge tool, called collector
    • Ensuring support for Java 7, 8, 9, and 10
  • Improvements and refactorings
    • Moved the Kafka readers and writers into a separate Gradle module.
      This is supposed to be a schematic example and other technology-specific
      modules are to follow. The goal is to improve the dependency management.
    • Many cleanups and improved test coverage
    • Restructuring of sub-projects tools have now separate projects and
      shared tool features can be found in kieker-tools
  • Infrastructure
    • Included Clover test coverage tool, migrated from FindBugs to
    • Replacing Jar file dependencies to Maven Central dependencies
    • Switched to Jenkins declarative pipeline
    • Updated the build system to provide separate bundles for all tools
  • Documentation
  • Bug fixes and improvements to code, performance, tests, documentation,
