Introduction

When executing chaos experiments, you may want to mute your Instana alerts not to bother your ops colleagues. You can do this with this action.

To create a maintenance window the step can be dragged&dropped into the experiment editor.

Use Cases

  • Avoid false positives in your monitoring system
  • Avoid alerting your ops colleagues during chaos experiments
  • Avoid to distract your baselines during chaos experiments

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.
