proposal for presentation, week3: An Introduction to Application-level Chaos Engineering and Its Tools

[nagavem]

Presentation by Nagasudeep [email protected]
and Akhil Yerrapragada - [email protected]

Introduction to chaos engineering and its tools

Fault injection vs Chaos engineering differences.

Comparision between chaos machine with other chaos engineering systems (Ex: Simian Army).

Performace evaluation of a spring application using chaos machine/chaos monkey.

Please note that we will be refering to "A Chaos Engineering System for Live Analysis and
Falsification of Exception-handling in the JVM
" to consider some inputs as we see very little documentation available.

Hi @nagavem , thanks for the PR! Could you also add a short statement (1-3 sentences) about the relevance and timeliness for Chaos Engineering & Devops in your README? (see presentation#how-to-register-your-topic)

Another issue to be fixed is the folder's name. You don't need to add the @kth.se part. The folder's name should be Vemula-vemula-akhilyerrapragada905 instaed.

Hi! As part of our presentation which includes some evaluation results using tools like "Chaos monkey","Gremlin" and "ChaosMachine", I was trying to work with chaos machine on a springboot appliaction. I see an issue which says "Failed to execute goal fr.inria.gforge.spoon:spoon-maven-plugin:3.2:generate (default) on project WebApplication: Exception during the spoonify of the target project.". Tried looking for a solution online but no luck so far. I see this which is closed issue in spoon. Can you help me out in fixing this?

[gluckzhang]

Hi @akhilyerrapragadaa , thanks for trying ChaosMachine :)
Could you provide more debugging information? I assume you are using the annotation_processor, which is the only module in ChaosMachine using Spoon. You could also directly use ChaosMachine as a JavaAgent and provides a filter to inject exceptions into target packages.

@gluckzhang Thank you for looking into this.
Yes! I'm using annotation processor and the commands suggested in this repo.

1. I've impoted chaosmachine-annotation-processor.jar to my project and used the mentioned annotation
   

2. when running the application
   

3. Failed execution
   

Regarding using chaos machine as a java agent, thank you for the input. We will be trying it for sure! :)

Note: The tool is really cool!

@gluckzhang I have made some changes to the readme and also updated the folder name.
Do let me know if this is good to proceed.

[gluckzhang]

@akhilyerrapragadaa , thanks for the info. We are happy that you find ChaosMachine interesting. Feel free to give more feedback. I will take a look at the errors and be back to you later :)

We could even have more discussions in the future regarding research work on chaos engineering if you are interested in doing a master thesis :D

[gluckzhang]

Hi @nagavem, thanks for the updates! I would still expect some explanations about relevance and timeliness. Some other suggestions have been added directly to the README. When others are reading your contribution in this repo, the first thing they will take a look at is this README file, so let's polish the text a bit before merging it :)

[gluckzhang]

Thanks for the updates. Now the PR is merged!

Hi @akhilyerrapragadaa , this PR was merged before your fix. Have you created another PR to update the file? I didn't see it.
