Grafana plugins: Extending Observability for DevOps Engineers and SREs

Grafana plugins are a powerful way for DevOps engineers and SREs to extend and customize their monitoring, visualization, and observability workflows in Grafana. This article provides an in-depth look at what Grafana plugins are, the main types available, how to install and manage them, and practical examples to help you get started.

What are Grafana plugins?

At its core, Grafana is a flexible open-source platform for monitoring and observability that connects to a wide range of data sources and visualizes complex metrics in dashboards. Grafana plugins enhance this core functionality by adding new ways to connect to data, visualize information, and integrate with DevOps tools and third-party services. Plugins allow users to tailor Grafana to their unique needs, making it a key platform for modern DevOps and SRE teams.
Grafana's extensibility through plugins and APIs allows for seamless integration with other DevOps tools, enhancing its capabilities and adaptability.[1]

Types of Grafana plugins

There are three main categories of Grafana plugins:

  • Data source plugins: Enable Grafana to connect to external databases, monitoring tools, or APIs and fetch data in a Grafana-friendly format.[2][13]
  • Panel (Visualization) plugins: Add new ways to visualize data, such as gauges, heatmaps, or status panels.[2]
  • App plugins: Bundle dashboards, data sources, visualizations, and custom pages to provide integrated solutions for specific needs (e.g., monitoring Kubernetes, CI/CD pipelines).[2]

Why are Grafana plugins essential for DevOps?

  • Unified observability: Aggregate data from diverse sources (Prometheus, Elasticsearch, Azure DevOps, GitHub, etc.) into a single dashboard.[1][3][5][7][13]
  • Custom visualizations: Choose or build tailored visualizations for unique metrics or logs.
  • Seamless integration: Connect Grafana with CI/CD tools, issue trackers, cloud providers, and more.
  • Workflow automation: Use app plugins to automate and streamline repetitive monitoring tasks.

Here are some practical examples of popular Grafana plugins that benefit DevOps teams:

    1. Restart Grafana and add the data source via the UI.
    2. Configure Azure DevOps access credentials.
    3. Create dashboards showing build status, deployment frequency, or PR trends.
  1. GitHub Data Source Plugin[13]
    Connects to the GitHub API to visualize repository activity, issues, and pull requests. Great for SREs tracking release velocity or open bug trends.
    1. Configure API access tokens in the data source settings.
    2. Build panels showing PR counts, issue status, or commit frequency.
  2. Stat Panel Plugin
    A popular panel plugin for quick-glance metrics like uptime, error rates, or deployment status.

Add the Stat panel to any dashboard and bind to a metric. For example, showing HTTP 5xx errors:

sum(rate(http_requests_total{status=~"5.."}[5m]))

Install:

grafana-cli plugins install grafana-github-datasource

Install the plugin:

grafana-cli plugins install grafana-azuredevops-datasource

Azure DevOps Data Source Plugin[5][7]
This plugin lets you query data from Azure DevOps, such as build pipelines, releases, and pull requests, directly in Grafana.Example query for listing build pipelines (using the plugin's query editor):

{
  "service": "pipelines",
  "resource": "runs",
  "project": "YourProjectName"
}

Prometheus Data Source Plugin
This is the default plugin for integrating Prometheus metrics into Grafana dashboards. Prometheus is widely used for infrastructure and application monitoring in Kubernetes and cloud-native environments.

1. Go to Configuration > Data Sources in Grafana UI.
2. Click Add data source and select Prometheus.
3. Enter your Prometheus server URL and save.

Once added, you can use PromQL to query metrics and visualize them in panels.

How to install and manage Grafana plugins

Grafana plugins can be installed from the official Grafana plugin catalog or by using the Grafana CLI. Here’s how DevOps engineers and SREs can manage plugins efficiently:

Install a plugin via Grafana CLI

grafana-cli plugins install <plugin-id>
systemctl restart grafana-server

Replace <plugin-id> with the ID from the Grafana plugin catalog.

Install a plugin via the Grafana UI

  1. Log in to Grafana as an admin.
  2. Go to Configuration > Plugins.
  3. Find the desired plugin and click Install.

Upgrading and removing plugins

# Upgrade all plugins
grafana-cli plugins update-all

# Remove a plugin
grafana-cli plugins uninstall <plugin-id>

Building custom Grafana plugins

For advanced use cases, you may need a custom plugin to connect to proprietary systems or create bespoke visualizations. Grafana provides a robust plugin platform and CLI tools for plugin development.[2]

Scaffolding a new plugin

npx @grafana/create-plugin my-custom-plugin

This command sets up a development environment with sample code, TypeScript, and React components. From here, you can customize your data source, panel, or app plugin logic.

Useful resources

  • Official Grafana plugins documentation: Setup, querying, and plugin lifecycle management.[9]
  • Grafana Plugin Platform: React component library, CLI tools, and guidance for building high-quality plugins.[2]

Best practices for using Grafana plugins in production

  • Version pinning: Always pin plugin versions for stability across environments.
  • Access control: Use Grafana’s RBAC features to restrict plugin management to trusted users.
  • Security: Review plugin source code or use only officially maintained plugins, especially for data sources with sensitive information.
  • Monitoring plugin health: Regularly check for plugin updates and monitor logs for compatibility issues after Grafana upgrades.

Conclusion

Grafana plugins are essential for DevOps engineers and SREs aiming for comprehensive, scalable, and actionable observability. With an ever-growing ecosystem of plugins and the ability to build your own, Grafana adapts to virtually any monitoring need — from aggregating CI/CD pipeline metrics to visualizing custom KPIs. Start exploring the Grafana plugin catalog today to unlock the full potential of your observability platform.
