Wiztelemetry Tracing

WizTelemetry Tracing

Overview

WizTelemetry Tracing is an extension component in the KubeSphere Observability Platform that provides distributed tracing functionality based on the OpenTelemetry standard.

When to Use

• Installing or configuring the WizTelemetry Tracing extension
• Understanding tracing architecture (Generator + Operator + Collector + Agent)
• Using the tracing query API to query traces, spans, service graphs
• Configuring OpenTelemetry auto-instrumentation for applications

Components

Dependencies

• WizTelemetry Platform Service (whizard-telemetry): 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

bashCopy code
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):

Copy code
Available clusters: host, dev
Which clusters do you want to deploy WizTelemetry Tracing to?

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

MUST do this to get the latest version:

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

This outputs the latest version (e.g., 1.0.6). Note this down - you'll use it in the InstallPlan.

Step 3: Get Generator Endpoint

Get a node IP from the target cluster:

bashCopy code
kubectl get nodes -o jsonpath='{.items[0].status.addresses[?(@.type=="ExternalIP")].address}' 2>/dev/null || \
kubectl get nodes -o jsonpath='{.items[0].status.addresses[?(@.type=="InternalIP")].address}'

This outputs a node IP (e.g., 192.168.1.100). Use this as the generator endpoint.

If multiple shards (e.g., generator.shardCount: 3), generate all endpoints:

bashCopy code
NODE_IP="<NODE_IP>"
for i in 0 1 2; do
  PORT=$((32318 + i))
  echo "  - http://${NODE_IP}:${PORT}"
done

Replace <NODE_IP> with the actual node IP from the previous command.

Step 4: Confirm Configuration with User

Before creating the InstallPlan, confirm the following with the user:

Copy code
I'll install WizTelemetry Tracing with the following configuration:
- Version: <VERSION>
- Target clusters: <TARGET_CLUSTERS>
- Generator endpoint: http://<NODE_IP>:32318
- OpenSearch endpoint: <OPENSEARCH_ENDPOINT>

Do you want to proceed? (yes/no)

If user confirms, proceed to create the InstallPlan. If not, adjust the configuration based on user feedback.

Step 5: Create InstallPlan

CRITICAL: InstallPlan metadata.name MUST be wiztelemetry-tracing. 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.

Based on your selections:

• Target clusters: User-confirmed cluster names
• OpenSearch endpoint: User-provided (default: https://opensearch-cluster-data.kubesphere-logging-system.svc:9200)
• OpenSearch credentials: User-provided (default user: admin)

Template

yamlCopy code
apiVersion: kubesphere.io/v1alpha1
kind: InstallPlan
metadata:
  name: wiztelemetry-tracing
  namespace: kubesphere-system
spec:
  extension:
    name: wiztelemetry-tracing
    version: <VERSION>  # From Step 2
  enabled: true
  upgradeStrategy: Manual
  config: |
    global:
      generator:
        endpoints:
          - http://<HOST_NODE_IP>:32318
      storage:
        opensearch:
          auth:
            strategy: basic
            user: <OPENSEARCH_USER>
            password: <OPENSEARCH_PASSWORD>
          endpoints:
            - <OPENSEARCH_ENDPOINT>
    generator:
      shardCount: 1
      service:
        nodePort: 32318
  clusterScheduling:
    placement:
      clusters:
        - <TARGET_CLUSTERS>

Replace placeholders:

• <VERSION>: From Step 2 (e.g., 1.0.6)
• <HOST_NODE_IP>: Node IP from Step 3 (e.g., 192.168.1.100)
• <OPENSEARCH_USER>: OpenSearch username
• <OPENSEARCH_PASSWORD>: OpenSearch password
• <OPENSEARCH_ENDPOINT>: OpenSearch endpoint (e.g., https://opensearch-cluster-data.kubesphere-logging-system.svc:9200)
• <TARGET_CLUSTERS>: User-confirmed cluster names

Enable Agent (Log File Collection)

To enable tracing data collection from local log files, set agent.enabled: true in the config. This deploys a DaemonSet that scans log files and forwards traces to the generator.

Enable Demo

To enable the OpenTelemetry Demo (generates sample trace data), set demo.enabled: true in the config.

Send Traces to Tempo

To forward traces to Tempo instead of OpenSearch, modify the collector.collector.config:

yamlCopy code
collector:
  enabled: true
  collector:
    config: |
      exporters:
        otlp:
          endpoint: <TEMPO_DISTRIBUTOR_GRPC_ENDPOINT>
          headers:
            x-scope-orgid: wiztelemetry-tracing-ks
          tls:
            insecure: true
      service:
        pipelines:
          traces:
            exporters:
              - otlp
              - otlphttp

Multiple Generator Instances

To scale the generator for higher throughput, increase generator.shardCount and update global.generator.endpoints:

yamlCopy code
global:
  generator:
    endpoints:
      - http://<HOST_NODE_IP>:32318
      - http://<HOST_NODE_IP>:32319
      - http://<HOST_NODE_IP>:32320

generator:
  shardCount: 3
  service:
    nodePort: 32318

shardCount must match the number of endpoints in global.generator.endpoints. The nodePort of each shard increases in sequence starting from the configured service.nodePort.
