Expected Dashboard Sections and Panels

(Can be tweaked (add or remove panels/sections) according to available metrics)

General Overview

This section provides a high-level overview of the cert-manager's health and performance metrics, allowing for a quick assessment of the system's current state.

Panels

• Total Certificates Issued

  • Description: Displays the total number of certificates successfully issued by cert-manager.

• Active Certificates

  • Description: Shows the current number of active certificates managed by cert-manager.

• Certificate Requests

  • Description: Illustrates the number of certificate requests processed, including pending and completed requests.

• Uptime

  • Description: Displays the total uptime of the cert-manager since the last restart.

Certificate Issuance

This section focuses on the metrics related to the issuance of certificates, helping monitor the creation and provisioning of TLS certificates.

Panels

• Certificates Issued per Issuer

  • Description: Shows the number of certificates issued by each configured issuer (e.g., Let's Encrypt, HashiCorp Vault).

• Issuance Rate

  • Description: Displays the rate at which certificates are being issued over time, measured per minute/hour.

• Issuance Success Rate

  • Description: Illustrates the percentage of successful certificate issuances versus failed attempts.

Certificate Renewal

This section provides insights into the certificate renewal process, ensuring that certificates are renewed in a timely manner to maintain security.

Panels

• Certificates Pending Renewal

  • Description: Shows the number of certificates that are approaching their expiration date and are pending renewal.

• Renewal Success Rate

  • Description: Displays the percentage of successful renewals versus failed renewal attempts.

• Renewal Duration

  • Description: Illustrates the average time taken to renew certificates, highlighting any delays in the process.

Error Metrics

This section monitors errors and failures within cert-manager operations, aiding in the troubleshooting and resolution of issues.

Panels

• Certificate Issuance Errors

  • Description: Displays the number of errors encountered during the certificate issuance process.

• Renewal Errors

  • Description: Shows the number of errors that occurred during the certificate renewal process.

• API Server Errors

  • Description: Monitors errors related to communication with the Kubernetes API server, affecting cert-manager's functionality.

Resource Usage

This section provides insights into the resource consumption of the cert-manager, helping ensure it operates efficiently within the Kubernetes cluster.

Panels

• CPU Usage

  • Description: Displays the CPU usage by the cert-manager pods, indicating the processing load.

• Memory Usage

  • Description: Shows the memory consumption of the cert-manager, helping identify potential memory leaks or inefficiencies.

• Pod Restarts

  • Description: Monitors the number of times cert-manager pods have restarted, which could indicate stability issues.

API and Event Metrics

This section tracks API requests and events handled by cert-manager, providing visibility into its interactions within the Kubernetes ecosystem.

Panels

• API Request Rate

  • Description: Displays the rate of API requests processed by cert-manager over time.

• Event Processing Rate

  • Description: Shows the number of Kubernetes events processed by cert-manager, indicating its responsiveness to cluster changes.

• Failed API Requests

  • Description: Monitors the number of failed API requests, aiding in identifying communication issues with the Kubernetes API server.

Expected Dashboard Variables

• namespace – Filter metrics based on the Kubernetes namespace where cert-manager is deployed.
• issuer – Select specific certificate issuers (e.g., Let's Encrypt, HashiCorp Vault) to filter metrics.
• certificate_name – Filter metrics based on specific certificate names.
• cluster – For multi-cluster setups, filter metrics based on the Kubernetes cluster.
• deployment.environment
