ChaosAgent is a agent which can be attach to JVM, it is used to provide the inject trigger point for JVMChaos(byteman).
For example, when we want to trigger garbage collection, need to specified a CLASS and METHOD in byteman's rule file. ChaosAgent provide the trigger CLASS(org.chaos_mesh.chaos_agent.TriggerThread) and METHOD(triggerFunc), it will execute triggerFunc every 5 second.
The byteman's rule file looks like below:
RULE gc test
CLASS org.chaos_mesh.chaos_agent.TriggerThread
METHOD triggerFunc
HELPER org.chaos_mesh.byteman.helper.GCHelper
AT ENTRY
IF true
DO
gc();
ENDRULE
