Everything in Sight: Kieker's WebGUI in Action (Tutorial)

In order to process monitoring data, the Kieker framework provides an API to define and execute pipe-and-filter oriented analysis networks. We develop a multiuser web application, which uses this API to allow graphical assembling and execution of Kieker analysis projects. Besides supporting programmers with the configuration of pipe-and-filter networks, the application helps to assemble so-called cockpits. Cockpits visualize results from running analyses and provide a live view on software systems within the web application using widgets. Such cockpits can be a useful tool for administrators to observe a system. In this paper, we outline Kieker’s pipe-and-filter API and introduce the web application. We put a main focus on its features, current development state, and planned future. Using an exemplary analysis, we show the tool and its potentials in action.
