Chaos Mesh Data Source

Grafana data source plugin for Chaos Mesh.

Features

• Visualize Chaos Events on the table
• Show Chaos Events on the graph with Annotations
• Display different Chaos Events by Variables

Installation

grafana-cli plugins install yeya24-chaos-mesh-datasource

Setup

After installed, you can add this data source in Configuration -> Data Sources, then you will enter the settings page:

Only the URL field needs to be filled in and the others can be ignored.

Assuming you have a local Chaos Mesh installed, the dashboard will default export its API in port 2333. So, if you don't modify anything, you can simply fill http://localhost:2333 into it.

Then use port-forward to active:

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

Finally, click Save & Test to test the connection. If it shows that the connection is successful, then the setup work has been completed.

Options

Except for the url, this data source plugin has such options as below:

Query

Mostly, there will be three options to be responsible for filtering events:

• Experiment - Filter by the experiment name. Must be a full name.
• Namespace - Filter by different namespaces
• Kind - Filter by Chaos kinds

For real world usage, normally you will use these options in two situations:

• Specify all fields to locate an experiment more precisely.
• Let Experiment be empty to reduce the constraints of events filtering.
• Pass a variable like $experiment to query to control the events displaying.

Annotations

Edit example:

For usage, you can refer to the content described by Query.

Variables

If you choose the Variables type to query and select the data source to Chaos Mesh, You can get three different kind values.

Specify by choosing different metric:

• Experiment

  After selection, a text input field will occur, fill in the value of the experiment name you want to settle. Usually, you will fill in the partial name of some experiments to get the related experiment names.

  For example, you have two experiments:

  random-pod-kill and random-pod-failure

  Then you can fill random in the text field to get these experiments.

• Namespace

  After selection, all available namespaces will show in Preview of values directly. Without other operations.

• Kind

  Same as Namespace.
