Overview

WizTelemetry Logging is an extension component in the KubeSphere Observability Platform for log collection, processing, and storage.

• Installing or configuring the WizTelemetry Logging extension
• Understanding log collection architecture (container logs + disk log collection)
• Using the log query API to query logs

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 Logging 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-logging -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.
