Whizard Events

WizTelemetry Events

Overview

WizTelemetry Events is an extension component in the KubeSphere Observability Platform for Kubernetes event collection, processing, and storage.

When to Use

• Installing or configuring the WizTelemetry Events extension
• Understanding event collection architecture
• Using the event query API to query events

Components

Dependencies

• WizTelemetry Platform Service (whizard-telemetry): Required
• WizTelemetry Data Pipeline (vector): Required
• OpenSearch (opensearch): Required

Installation

Prerequisites

REQUIRED: Complete all steps in order before generating InstallPlan.

Step 1: Get Available Clusters and Confirm Target

⚠️ CRITICAL: DO NOT proceed until target clusters are determined.

Step 1.1: Get available clusters

kubectl get clusters -o jsonpath='{.items[*].metadata.name}'

Step 1.2: Determine target clusters

• If user explicitly specified target clusters in the request → Use those clusters directly, proceed to Step 2
• If user did NOT specify target clusters → Ask user to confirm which clusters to deploy to, then proceed to Step 2

Ask user (if not specified):

Available clusters: host, dev
Which clusters do you want to deploy WizTelemetry Events to?

Step 2: Get Latest Version (if not provided by user)

MUST do this to get the latest version:

kubectl get extensionversions -l kubesphere.io/extension-ref=whizard-events -o jsonpath='{range .items[*]}{.spec.version}{"\n"}{end}' | sort -V | tail -1

This outputs the latest version (e.g., 1.4.0). Note this down - you'll use it in the InstallPlan.

Install WizTelemetry Events

⚠️ IMPORTANT: Complete prerequisite steps BEFORE this step.

Based on your selections:

• Target clusters: User-confirmed cluster names

⚠️ CRITICAL: InstallPlan metadata.name MUST be whizard-events. DO NOT use any other name.

⚠️ CRITICAL: config field is YAML format. You MUST:

• Use the config structure exactly as shown in the template
• DO NOT add configuration fields that are not shown in the template
• DO NOT modify the structure or hierarchy

⚠️ CRITICAL: All placeholders MUST be replaced with actual values. DO NOT leave them as placeholders.

Template

apiVersion: kubesphere.io/v1alpha1
kind: InstallPlan
metadata:
  name: whizard-events
spec:
  extension:
    name: whizard-events
    version: <VERSION>  # From Step 2
  enabled: true
  upgradeStrategy: Manual
  clusterScheduling:
    placement:
      clusters:
        - <TARGET_CLUSTERS>

Replace placeholders:

• <VERSION>: From Step 2 (e.g., 1.4.0)
• <TARGET_CLUSTERS>: User-confirmed cluster names

Note: OpenSearch sink configuration (endpoints, auth) is provided by the vector extension. Make sure vector is installed and configured with OpenSearch before installing events.

Event Query API

Query Events

curl -X GET "http://whizard-telemetry-apiserver.extension-whizard-telemetry.svc:80/kapis/logging.kubesphere.io/v1alpha2/events?operation=query&sort=desc&size=10&cluster=host" \
  -H "X-Remote-User: admin"

Query Parameters:

Extension Operations

Check Extension Status

kubectl get installplan whizard-events
kubectl get extensionversions -l kubesphere.io/extension-ref=whizard-events

Uninstall Extension

Uninstall from all clusters:

kubectl delete installplan whizard-events

Uninstall from specific cluster:

To remove WizTelemetry Events from a specific cluster, update the InstallPlan by removing that cluster from clusterScheduling.placement.clusters:

apiVersion: kubesphere.io/v1alpha1
kind: InstallPlan
metadata:
  name: whizard-events
spec:
  extension:
    name: whizard-events
    version: <VERSION>
  enabled: true
  upgradeStrategy: Manual
  clusterScheduling:
    placement:
      clusters:
        - <REMAINING_CLUSTERS>  # Remove the cluster you want to uninstall from
