WizTelemetry Notification

Overview

WizTelemetry Notification is the notification component of the KubeSphere observability platform. It receives alerts, cloud events, and audit logs in a multi-tenant Kubernetes environment and distributes notifications to different channels based on tenant labels (e.g., namespace).

Components

Component	Description	Default
notification-manager	Core notification management, receives alerts, dispatches to channels	true
alertmanager (v0.27.0)	Alert routing, deduplication, aggregation, silencing	true
alertmanager-proxy	Alertmanager API proxy, NodePort 31093	true
notification-history	Stores sent notifications via Vector to OpenSearch	true

Dependencies

Dependency	Type	Required
whizard-telemetry	extension	Required
vector (WizTelemetry Data Pipeline)	extension	Required only notification history is enabled
opensearch	extension	Required only notification history is enabled

CRDs

All CRDs belong to notification.kubesphere.io/v2beta2, scope is Cluster.

CRD	Kind	Description
`notificationmanagers.notification.kubesphere.io`	NotificationManager	Notification manager deployment spec (image, replicas, resources, sidecar, receiver config)
`receivers.notification.kubesphere.io`	Receiver	Tenant-level notification receiver, references Config
`configs.notification.kubesphere.io`	Config	Credential references (via Secret selectors), independent per channel
`routers.notification.kubesphere.io`	Router	Route alerts to receivers based on label matchers
`silences.notification.kubesphere.io`	Silence	Time-bounded silencing, supports matchers

Supported Notification Channels (11 channels)

Channel	Receiver Field	Config Field	Description
Email	`spec.email`	`spec.email`	SMTP with TLS/STARTTLS support
Slack	`spec.slack`	`spec.slack`	Slack webhook + token
DingTalk	`spec.dingtalk`	`spec.dingtalk`	ChatBot + group conversation
WeChat	`spec.wechat`	`spec.wechat`	ChatBot + group conversation
Feishu	`spec.feishu`	`spec.feishu`	ChatBot + group conversation
Webhook	`spec.webhook`	`spec.webhook`	Generic HTTP / HTTPS POST

Config → Receiver Association Mechanism

Config (credentials) --labels--> Receiver (via label selector) --labels--> Router (route matching)
                        │
                        └── namespace for multi-tenant isolation

Config's labels are used by Receiver's *ConfigSelector. Receiver's labels are used by Router's receiverSelector.

Installation

Prerequisites

REQUIRED: Complete all steps in order before generating InstallPlan.

Step 1: Get Latest Version (if not provided by user)

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

This outputs the latest version (e.g., 2.7.0). Note this down.

Step 2: Create InstallPlan

CRITICAL:

metadata.name MUST be whizard-notification
config field is YAML format
DO NOT add fields not shown in the template
Replace all placeholders with actual values

Basic installation:

apiVersion: kubesphere.io/v1alpha1
kind: InstallPlan
metadata:
  name: whizard-notification
spec:
  extension:
    name: whizard-notification
    version: <VERSION>  # From Step 1
  enabled: true
  upgradeStrategy: Manual

Disable notification history:

apiVersion: kubesphere.io/v1alpha1
kind: InstallPlan
metadata:
  name: whizard-notification
spec:
  extension:
    name: whizard-notification
    version: <VERSION>
  enabled: true
  upgradeStrategy: Manual
  config: |
    notification-history:
      enabled: false

Custom index format (monthly):

notification-history:
  sinks:
    opensearch:
      index:
        prefix: "{{ .cluster }}-notification-history"
        timestring: "%Y.%m"

Notification API

All APIs are at /kapis/notification.kubesphere.io/v2beta2/, routed through whizard-telemetry-apiserver.extension-whizard-telemetry.svc:80. No authentication token is required.

API Patterns

The API supports two levels of resources:

Level	URL Pattern	Resources
Global	`/{resources}`	`notificationmanagers`, `configs`, `receivers`, `routers`, `silences`, `secrets`, `configmaps`
Tenant	`/users/{user}/{resources}`	`configs`, `receivers`, `silences`, `secrets`, `configmaps` (NOT `notificationmanagers` or `routers`)

Supported HTTP methods: GET (list/detail), POST (create), PUT (update), PATCH (patch), DELETE (delete).

Query parameters for list endpoints: name, labelSelector, type, page, limit, ascending, orderBy.

Troubleshooting

Issue 1: Notifications Not Sent

Diagnosis steps:

# 1. Check if notification-manager is running
kubectl get pods -n kubesphere-monitoring-system -l notification-manager=notification-manager

# 2. Check if alertmanager receives alerts
kubectl logs -n kubesphere-monitoring-system -l app.kubernetes.io/name=alertmanager --tail=50

# 3. Check notification-manager logs
kubectl logs -n kubesphere-monitoring-system -l notification-manager=notification-manager -c notification-manager --tail=100 | grep -i error

# 4. Check if Receiver and Config exist
kubectl get receivers,configs -n kubesphere-monitoring-system

# 5. Check if silenced by Silence CR
kubectl get silences

Issue 2: Notification History Empty

# 1. Check if vector aggregator is running
kubectl get pods -n kubesphere-logging-system -l app.kubernetes.io/name=vector-aggregator

# 2. Check if vector-sinks secret exists
kubectl get secret vector-sinks -n kubesphere-logging-system

# 3. Check OpenSearch indices exist
# (requires OpenSearch API or Kibana)

Issue 3: Tenant Sidecar Not Responding

# Check sidecar logs
kubectl logs -n kubesphere-monitoring-system -l notification-manager=notification-manager -c tenant --tail=50

# Test sidecar API
kubectl exec -n kubesphere-monitoring-system deploy/notification-manager -- \
  curl -s "http://localhost:19094/api/v2/tenant?namespace=default"

Issue 4: Upgrade Still Using Old Images

# Check image tag config; manually set old tags block upgrades
kubectl get installplan whizard-notification -n kubesphere-system -o yaml | grep -i image

# Remove or update manually set image.tag in InstallPlan config

Important Notes

Dependency order: Install vector, and opensearch first if notification history is enabled
OpenSearch: Notification history sink credentials are auto-loaded from vector-sinks Secret
Multi-tenancy: Tenant sidecar (port 19094) resolves namespace → authorized user mappings
Image tags: Before upgrading, check and remove manually set image.tag to avoid pulling stale images
