Introduction to the Instana Extension
The Steadybit Instana Extension bridges the world of Steadybit and Instana. The extension adds checks to your Chaos Engineering experiments to validate detection of Instana events.
Integration and Functionality
Integration of Instana into Steadybit works via the Instana API. Thus, all you need is an API Key and the base URL of your Instana environment.
Integration of Instana in Steadybit
With the Event Check you can integrate your Instana events into your experiments. Check that your observability strategy is working as expected by verifying that Instana notices a problem which is injected by Steadybit.
With the Create Maintenance Window you can mute your alerting during an experiment to avoid false alarms and avoid incident processes.
Installation and Setup
To integrate the Instana extension with your environment, follow our setup guide.
Instana should detect a crash looping as incident
Intent
Verify that Instana alerts you that pods are not ready to accept traffic for some time.
Motivation
Kubernetes features a readiness probe to determine whether your pod is ready to accept traffic. If it isn't becoming ready, Kubernetes tries to solve it by restarting the underlying container and hoping to achieve its readiness eventually. If this isn't working, Kubernetes will eventually back off to restart the container, and the Kubernetes resource remains non-functional.
Structure
First, check that Instana has no critical events for an application perspective. As soon as one of the containers is crash looping, caused by the Steadybit attack crash loop, Instana should detect this via a critical event to ensure your on-call team is taking action.
