ExplorViz in a Nutshell

Live trace visualization of large software landscapes for comprehension of systems and applications [1] Selected Challenges

  • Finding abstractions to understand huge landscapes but also application-

level details

  • Live visualization of thousands or even millions of traces

Learnability

  • Setup requirements are manageable
  • Monitoring Management is easily accessible…
  • … but requires knowledge about program

internals

Usability Evaluation Results & Discussion Setup Efficiency

  • Faster execution of repeating tasks

Memorability

  • Workflow seemed to be memorable …
  • … but casual users might show another

result

Low error rate

  • System helped to resolve errors during
  • peration…
  • … but did not prevent flaws

Satisfaction

  • Graph design is pleasant to use
  • Management dialogs require more work

Conclusions & Future Work

24 More research required

  • Wider range of probands

Observations indicate good usability (Simple) Monitoring Management works

  • Prevent errors
  • Provide templates
  • Refactor GUI forms

Application Discovery method works

  • JDK 9 usage?
  • Cryptic execution

commands?
