Apply CPU stress inside a target Java process on a Linux machine for a configurable duration so you can test how the JVM behaves under compute pressure.

Apply memory stress inside a target Java process on a Linux machine for a configurable duration so you can test how the JVM behaves under memory pressure.

Throw a configured exception from a target class and method in a Java process on a Linux machine so you can test how the application handles unexpected exceptions.

Add latency to a target class and method in a Java process on a Linux machine so you can test how the application behaves when an internal method slows down.

Override the return value of a target class and method in a Java process on a Linux machine so you can test how callers handle unexpected return data.

Force garbage collection in a target Java process on a Linux machine for a configurable duration so you can test how the workload behaves under repeated GC events.

Generate sustained CPU load inside a JVM running in a target Kubernetes pod to test how the application behaves when its Java process is starved of CPU.

Cause Kafka producer or consumer calls from a JVM running in a target Kubernetes pod to throw a configurable exception on a chosen topic so you can test caller error handling.

Add a configurable delay to Kafka producer or consumer calls from a JVM running in a target Kubernetes pod, scoped by topic, so you can test timeout, back-pressure, and lag behavior under slow Kafka traffic.

Cause a specific Java method in a JVM running in a target Kubernetes pod to throw a configurable exception so you can test how callers handle the failure.

Add a configurable delay to every invocation of a specific Java method in a JVM running in a target Kubernetes pod so you can test how callers and dependents behave under slow methods.

Override the return value of a specific Java method in a JVM running in a target Kubernetes pod so you can test how callers behave when a method silently returns wrong data.

Cause MongoDB operations from a JVM running in a target Kubernetes pod to throw a configurable exception on a chosen database, collection, and operation so you can test caller error handling.

Add a configurable delay to MongoDB operations from a JVM running in a target Kubernetes pod, scoped by database, collection, and operation, so you can test timeout and back-pressure behavior under a slow MongoDB.

Cause Solace publisher or subscriber calls from a JVM running in a target Kubernetes pod to throw a configurable exception on a chosen topic or queue so you can test caller error handling.

Add a configurable delay to Solace publisher or subscriber calls from a JVM running in a target Kubernetes pod, scoped by topic or queue, so you can test timeout and back-pressure behavior under slow Solace messaging.

Cause JDBC calls from a JVM running in a target Kubernetes pod to throw a configurable exception on a chosen table and SQL operation so you can test caller error handling.

Add a configurable delay to JDBC calls from a JVM running in a target Kubernetes pod, scoped by table and SQL operation, so you can test timeout and back-pressure behavior under a slow database.

Force the JVM in a target Kubernetes pod to run garbage collection on a configurable schedule so you can test how the application behaves under repeated GC pauses.
