Wilma Plugin Example - Random Error Generator | ||
=============================== | ||
|
||
Purpose of this example | ||
--------------------------------------- | ||
This plugin example was created to show how Wilma can be acted as a special kind of Chaos Monkey. See the original Chaos Monkey [tool here](https://github.com/Netflix/chaosmonkey), which tool is created by Netflix for AWS. | ||
So what kind of Chaos Monkey this example will show? This will simulate the following error situations: | ||
|
||
- E404 error will be received as response in a certain percentage of the requests, randomly | ||
- E500 error will be received as response for another percentage of the requests, randomly | ||
- response timeout will be cause for another percentage of the requests, randomly | ||
|
||
|
||
Implementation | ||
--------------------------------------- | ||
TBD. | ||
|
||
Build | ||
----- | ||
``` | ||
#run extras: Random Error Generator example | ||
./gradlew -b wilma-extras/random.error.generator/build.gradle clean build | ||
``` | ||
After a successful run you will find the wilma plug-in in folder: wilma-extras/random.error.generator/build/libs as a jar file. | ||
|
||
How to Use it? | ||
----------------------------------------- | ||
- Ensure that the compiled randomErrorGenerator jar is available for your Wilma instance | ||
- Configure Wilma to use it (see example configuration above) | ||
