Cert-Manager Dashboard Integration with OpenTelemetry and SigNoz

This PR introduces a monitoring setup for cert-manager using OpenTelemetry and SigNoz, providing comprehensive insights into cert-manager’s health and performance. This integration allows real-time tracking of certificate issuance, renewal, and error metrics, supporting easier monitoring and troubleshooting of cert-manager activities in Kubernetes environments.

Key Components

1. Dashboard Name: Cert-Manager Dashboard

2. Dashboard Sections:

   • General Overview: High-level view of cert-manager’s health and performance metrics, for a quick assessment of system status.

   • Certificate Issuance: Tracks certificate issuance metrics, aiding in the monitoring of certificate creation and provisioning.

   • Certificate Renewal: Provides insights into the certificate renewal process, ensuring timely renewals to maintain security.

   • Error Metrics: Monitors errors and failures in cert-manager operations, supporting troubleshooting and issue resolution.

   • Resource Usage: Displays cert-manager’s resource consumption within the Kubernetes cluster, helping ensure efficient operations.

   • API and Event Metrics: Tracks API requests and events, providing visibility into cert-manager’s interactions within the Kubernetes ecosystem.

3. Dashboard Variables:

   • namespace: Filters metrics by the Kubernetes namespace of cert-manager.
   • issuer: Filters by certificate issuer (e.g., Let’s Encrypt, HashiCorp Vault).
   • certificate_name: Filters by specific certificate names.
   • cluster: Supports multi-cluster setups by filtering metrics based on the Kubernetes cluster.
   • deployment.environment: Filters metrics by the deployment environment.

Additional Notes

• Configuration Requirements: Requires a Kubernetes cluster (e.g., Minikube or managed clusters).
• SigNoz Ingestion Settings: Customizable OpenTelemetry configuration for routing metrics to SigNoz, with environment variables for specific deployments.

This PR establishes a structured approach for cert-manager monitoring with OpenTelemetry and SigNoz, delivering essential insights for effective certificate management and troubleshooting in Kubernetes.
