Assuming you have Chaos Mesh installed locally, the Chaos Dashboard will export the API on port 2333 by default. So, if you haven't changed anything, you can fill in http://localhost:2333.

Then use the port-forward command to make the API externally accessible:

kubectl port-forward -n chaos-mesh svc/chaos-dashboard 2333:2333

Finally, click Save & test to test the connection. If it shows a successful notification, the setup is complete.

Authentication

If you deploy Chaos Mesh with permission authentication, you need to add the Authorization header to the configuration. You can follow the steps below to add the header:

1. Click the Add header button.
2. Fill in the Authorization in the Header field.
3. Follow this section to get the token.
4. Fill in the Bearer YOUR_TOKEN in the Value field.

Then don't forget to click Save & test to test the connection.

Query

The data source plugin looks at the Chaos Mesh through the lens of events, and the following options are responsible for filtering the different events:

• Object ID

  Filter by object uuid.

• Namespace

  Filter by different namespace.

• Name

  Filter by object name.

• Kind

  Filter by kind (PodChaos, NetworkChaos, Schedule...). You can also input an arbitrary kind if you implement a new kind in Chaos Mesh.

• Limit

  Return at most this many events, newest first, across all selected variable values. Leave empty or use a negative integer for no limit. Use 0 to return no events.

The Object ID, Namespace, Name, and Kind filters are passed as parameters to the /api/events API.

Variables

The data source plugin supports adding query variables by different metrics:

• Namespace

  After selection, all available namespaces will show in the Preview of values directly.

• Kind

  Same as Namespace. Retrieve all kinds.

• Experiment/Schedule/Workflow

  Same as Namespace. Retrieve current all experiments/schedules/workflows.

  You can also specify the queries to further filter the values, for example, ?namespace=default will only retrieve the experiments/schedules/workflows in the default namespace.

Annotations

You can integrate events into panels via annotations, the following is a sample creation, it will retrieve all PodChaos events:
