Grafana Overview

Grafana is an open-source observability platform used for visualizing metrics, logs, and traces from various backends. It provides an interactive UI for creating dashboards, setting alerts, and correlating data across multiple sources. With its extensible plugin system, Grafana connects to a wide array of databases and services. High availability, scalability, and role-based access controls make it suitable for large production environments. Frequent releases introduce new features, security patches, and occasional breaking changes.

Chkk Coverage

​

Curated Release Notes

Chkk keeps watch over Grafana’s upstream releases to highlight security patches, deprecated APIs, and new features relevant to your clusters. It condenses verbose changelogs into key operational insights, so you can quickly see what requires attention. Any known issues or breaking changes are flagged early, helping you plan upgrades with minimal guesswork. By highlighting direct impacts to your environment, Chkk takes the guesswork out of tracking Grafana upgrades.

​

Preflight & Postflight Checks

Before upgrading, Chkk automatically inspects your Kubernetes version, Grafana config, dashboards, and plugins to confirm compatibility with the new release. It warns you if specific flags, authentication settings, or dependencies will break. Post-upgrade, it verifies that Grafana is fully operational, including data source connectivity and alert rules. These checks reduce the risk of discovering issues only after the change has taken effect.

​

Version Recommendations

When your current Grafana version nears end-of-life, Chkk proactively recommends stable upgrade paths, weighing factors like recent security advisories and known bugs. It accounts for the maturity of new features, ensuring you don’t jump prematurely to versions lacking broad community validation. Urgent patches are flagged separately if they address critical vulnerabilities. This data-driven approach balances novelty against reliability, giving you a well-rounded upgrade strategy.

​

Upgrade Templates

Chkk provides repeatable Upgrade Templates for both in-place and blue-green strategies. Each template includes pre-upgrade backups, step-by-step instructions, and health checks to minimize downtime. In-place upgrades streamline the process on smaller clusters, while canary deployments reduce risk by running two versions in parallel. These templates enable a smooth experience whether you’re updating a small Dev cluster or a global production environment.

​

Preverification

Chkk can perform a full test run of your Grafana upgrade in a representative “digital twin” environment. It copies your configuration, dashboards, and data sources to detect any plugin or schema issues before touching production. Failures in the simulated upgrade guide you to fix configurations or resource constraints. By isolating possible pitfalls early, you avoid disruptive surprises on live clusters.

​

Supported Packages

Chkk accommodates Grafana deployments via Helm, Kustomize, or straight Kubernetes manifests. It understands custom images, private registries, and specialized builds, so you can maintain existing workflows without compromise. If using GitOps, Chkk can analyze your manifests and automatically propose changes needed for safe upgrades. This unified approach helps ensure consistency and compliance across all environments you manage.

Common Operational Considerations

• Performance Optimization: Use caching or downsampling to prevent slow queries, and allocate sufficient CPU/memory to Grafana. Monitor its internal metrics to detect bottlenecks early.
• Plugin & Data Source Management: Keep plugins updated to compatible versions and restrict who can install them. Validate connectivity and credentials periodically, especially after upgrades.
• Alerting Best Practices: Create clear alert rules with meaningful thresholds to avoid noise. Ensure redundant notification channels and apply silences during maintenance windows.
• Storage & Retention: Use MySQL/PostgreSQL in production for Grafana’s database, and back it up routinely. Align retention policies with your observability stack to avoid data mismatches.
• Scaling Strategies: Deploy multiple Grafana instances with a shared database for HA, and shard heavy queries or dashboards if needed. Use load balancing to distribute user sessions effectively.
• Security & RBAC: Integrate with SSO to enforce centralized authentication, and limit admin roles. Secure data source credentials and network access to protect sensitive observability data.
