Self-Hosting DORA Metrics Dashboard

This document outlines how to self-host a DORA (DevOps Research and Assessment) metrics dashboard. Self-hosting provides control over your data, but requires technical expertise. Several open-source and commercial solutions exist. This guide discusses general approaches and considerations. It does not cover specific code implementations.

Understanding DORA Metrics​

DORA metrics are a set of key performance indicators (KPIs) that measure the performance of software development teams. They provide valuable insights into team velocity, stability, and overall effectiveness. The core DORA metrics are:

  • Deployment Frequency: How often code is successfully released to production.
  • Lead Time for Changes: The time it takes for a code commit to reach production.
  • Mean Time to Recovery (MTTR): The average time it takes to restore service after an incident.
  • Change Failure Rate: The percentage of deployments that cause a failure in production.

Choosing a Self-Hosting Approach​

Several options exist for self-hosting a DORA metrics dashboard, each with varying levels of complexity:

  1. Build Your Own: This involves developing a custom solution from scratch, giving you maximum flexibility but requiring significant development effort. You'll need to:

    • Collect data from your CI/CD pipelines, version control systems, incident management tools, and other relevant sources.
    • Store the data in a database.
    • Develop a dashboard to visualize the metrics.
    • Implement alerting and reporting capabilities.

  2. Leverage Open-Source Tools: Several open-source tools can help you collect, store, and visualize DORA metrics. This reduces development effort but may require configuration and customization. Examples:

    • Prometheus: A popular open-source monitoring and alerting toolkit that can be used to collect DORA metrics.
    • Grafana: An open-source data visualization tool that can be used to create dashboards based on Prometheus data.
    • Jaeger/Zipkin: Distributed tracing systems useful for measuring lead time for changes.
    • Various CI/CD plugins/scripts: Many CI/CD systems have plugins or scripts for extracting DORA-related data.
    • DevLake: An open-source dev data platform for measuring DORA metrics (https://devlake.apache.org/).

  3. Extend Existing Monitoring Solutions: If you already use a monitoring platform like Datadog, New Relic, or Dynatrace, you may be able to extend it to collect and visualize DORA metrics. This can be a simpler approach if your platform already supports custom metrics and dashboards.

Prerequisites​

Regardless of the chosen approach, you'll need the following:

  • Infrastructure: Servers or cloud resources to host your database, data processing pipelines, and dashboard.
  • Database: A database to store the collected metrics data (e.g., PostgreSQL, MySQL, TimescaleDB, InfluxDB). Timeseries databases are often favored for performance.
  • Programming Skills: Proficiency in programming languages like Python, Go, or JavaScript, depending on the tools and technologies you choose.
  • Data Engineering Skills: Understanding of data collection, transformation, and storage techniques.
  • CI/CD System Knowledge: Familiarity with your CI/CD pipelines and how to extract relevant data.
  • DevOps Tooling Knowledge: How to query and integrate with incident management systems, source control, etc.
  • Monitoring Setup: A configured environment including access to API keys and other credentials to query required source data.

General Steps for Self-Hosting​

The specific steps will vary depending on your chosen approach, but the following provides a general outline:

  1. Identify Data Sources:

    • Determine the systems that contain the data required to calculate DORA metrics (e.g., CI/CD tools, version control systems, incident management tools).
    • Understand the data formats and APIs provided by these systems.

  2. Implement Data Collection:

    • Develop scripts or pipelines to collect data from the identified sources.
    • Automate data collection using scheduling tools like cron or Airflow.

  3. Transform and Store Data:

    • Clean and transform the collected data to ensure consistency and accuracy.
    • Store the transformed data in your chosen database.

  4. Develop the Dashboard:

    • Choose a visualization tool (e.g., Grafana) or develop a custom dashboard using a framework like React or Vue.js.
    • Connect the dashboard to your database and create visualizations for the DORA metrics.

  5. Implement Alerting and Reporting (Optional):

    • Configure alerts to notify you of significant changes in DORA metrics.
    • Generate regular reports to track progress and identify areas for improvement.

  6. Secure the Infrastructure:

    • Implement appropriate security measures to protect your data and infrastructure. Use proper access control.
    • Encrypt data in transit and at rest.
    • Regularly update your systems to address security vulnerabilities.

Example: Using Prometheus and Grafana​

This provides a conceptual example.

  1. Collect Data Using Prometheus Exporters/Scripts:

    • Develop scripts or use existing exporters to collect DORA metrics from your CI/CD pipelines and other systems.
    • Expose these metrics in Prometheus format (text-based format that Prometheus can scrape).
    • Configure Prometheus to scrape these metrics endpoints.

  2. Configure Prometheus:

    • Install and configure Prometheus to scrape your metrics endpoints.
    • Define alerting rules in Prometheus to trigger notifications based on metric thresholds.

  3. Create Grafana Dashboards:

    • Install and configure Grafana.
    • Add Prometheus as a data source in Grafana.
    • Create dashboards in Grafana to visualize the DORA metrics collected by Prometheus.
    • Use PromQL (Prometheus Query Language) to query and aggregate the data.

Challenges and Considerations​

  • Data Complexity: Collecting and transforming data from various sources can be complex and time-consuming.
  • Data Accuracy: Ensuring the accuracy and consistency of the data is crucial for reliable metrics.
  • Maintenance Overhead: Self-hosting requires ongoing maintenance and support.
  • Scalability: Your solution should be scalable to handle increasing data volumes and user traffic.
  • Security: Implement robust security measures to protect your data and infrastructure.
  • Time Investment: Building and maintaining a self-hosted DORA metrics dashboard requires significant time and effort.
  • Tooling Expertise: Expertise in the chosen tooling stack will improve the chances of a successful implementation.

When to Consider Self-Hosting​

  • Data Privacy and Security Concerns: If you have strict data privacy and security requirements that cannot be met by cloud-based solutions.
  • Customization Needs: If you need to heavily customize the dashboard to meet your specific requirements.
  • Integration with Existing Systems: If you need to integrate with existing systems that are not supported by commercial solutions.
  • Cost Considerations: In some cases, self-hosting can be more cost-effective than commercial solutions, especially for large organizations.
  • Regulatory Requirements: Some industries have regulatory requirements around where development/operational data is stored.

Alternatives to Self-Hosting​

  • Cloud-Based DORA Metrics Platforms: Consider commercial DORA metrics platforms like LinearB, Haystack, or Sleuth if self-hosting is not feasible. These platforms typically offer pre-built integrations, dashboards, and reporting capabilities. Many CI/CD platforms also provide DORA metrics as part of their offering.

This guide provides a general overview of self-hosting a DORA metrics dashboard. Carefully evaluate your requirements and choose the approach that best suits your needs and resources. Consider the significant upfront and ongoing maintenance efforts involved.
