    Identifying Bottlenecks in a Visualization Platform for Tracing Adaptation Decisions
    (Softwaretechnik-Trends Band 39, Heft 4, 2019) Pfannemüller, Martin; Becker, Christian
    Measuring the performance of different operations as part of a software system can help to identify performance bottlenecks. This information can be used to improve the performance of the monitored system. In previous work, we proposed a visualization platform for observing and understanding adaptation decisions in self-adaptive systems. In this paper, we apply Kieker as a monitoring solution to measure the runtime of different operations based on the granularity of methods and tasks. As a result, we identified possibilities for improvements in our implementation.

    State Space Exploration for Planning Reconfigurations in Cloud-native Systems
    (Softwaretechnik-Trends Band 43, Heft 1, 2023) Ege, Florian; Höppner, Stefan; Tichy, Matthias; Stieß, Sarah
    Current self-adaptive systems do a poor job of coordinating their reconfigurations, and those that provide coordination capabilities offer few facilities to under stand how the system decides on its behavior. In this paper, we outline a state graph, the central artifact of a new approach for a self-adaptive system which utilizes simulations provided by Slingshot to decide on adaptations. Slingshot is a simulator on the Palladio ecosystem. We describe the structure of the state graph and its usage in our self-adaptive system approach. We further discuss technical challenges for Slingshot that need to be solved to implement the envisioned self-adaptive system.
