WizTelemetry Ruler
Overview
WizTelemetry Ruler is an extension component in the KubeSphere Observability Platform that provides event alerting and log alerting capabilities. It can define alerting rules for K8s native events, K8s/KubeSphere auditing events, and K8s logs, evaluate incoming event data and log data, and send alerts to specified receivers such as alertmanager, etc.
When to Use
Installing or configuring the WizTelemetry Ruler extension
Creating, updating, or deleting alerting rules (RuleGroup/ClusterRuleGroup)

Components Component Description Default Enabled whizard-telemetry-ruler Core ruler component for alerting true
Dependencies
WizTelemetry Platform Service (whizard-telemetry): RequiredWizTelemetry Events (whizard-events): Required if event alerting is enabledWizTelemetry Auditing (whizard-auditing): Required if auditing alerting is enabledWizTelemetry Logging (whizard-logging): Required if logging alerting is enabledWizTelemetry Notification (whizard-notification): Optional (for alert notification)WizTelemetry Data Pipeline (vector): Required if alerting persistence is enabledOpenSearch (opensearch): Required if alerting persistence is enabled
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 Ruler to?
Step 2: Get Latest Version (if not provided by user) MUST do this to get the latest version:
kubectl get extensionversions -n kubesphere-system -l kubesphere.io/extension-ref=whizard-telemetry-ruler -o jsonpath='{range .items[*]}{.spec.version}{"\n"}{end}' | sort -V | tail -1
This outputs the latest version (e.g., 1.5.0). Note this down - you'll use it in the InstallPlan.
Step 3: Get AlertManager Host (if configuring sink) Only perform this step if you need to configure sink for alert notifications.
The AlertManager proxy service (alertmanager-proxy) is deployed in the host cluster and exposed via NodePort (default port: 31093).
Step 3.1: Get a host node IP
kubectl get nodes -o jsonpath='{.items[0].status.addresses[?(@.type=="InternalIP")].address}'
Step 3.2: Confirm with user
Ask user to confirm the AlertManager host IP:
Detected AlertManager host: <NODE_IP>
Detected AlertManager port: 31093
Alert URL: http://<NODE_IP>:31093/api/v1/alerts
Do you want to use this URL for alert notifications?
If user confirms → Use http://<NODE_IP>:31093/api/v1/alerts as the sink URL
If user provides different URL → Use the user-specified URL
Note: If using WizTelemetry Notification extension, ensure it is installed before installing WizTelemetry Ruler.
Install WizTelemetry Ruler ⚠️ IMPORTANT: Complete prerequisite steps BEFORE this step.
Based on your selections:
Target clusters : User-confirmed cluster namesAlertManager URL : From Step 3 (if configuring sink) ⚠️ CRITICAL: InstallPlan metadata.name MUST be whizard-telemetry-ruler. 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 templateDO NOT modify the structure or hierarchy ⚠️ CRITICAL: All placeholders MUST be replaced with actual values. DO NOT leave them as placeholders.
