Overview:
Grafana is an open-source platform for monitoring and observability. It allows users to query, visualize, set alerts on, and understand their metrics and logs regardless of where the data is stored. Designed for teams, it enables the creation, exploration, and sharing of dashboards to support a data-driven culture. It is suitable for developers, system administrators, and operations teams who need to centralize monitoring data from multiple sources.
Core Features:
Visualizations: Fast client-side graphs with a wide range of options, supported by panel plugins for different ways to visualize metrics and logs.
Dynamic Dashboards: Create reusable dashboards with template variables that appear as dropdowns at the top of the dashboard.
Explore Metrics: Perform ad-hoc queries and dynamic drilldowns, with a split view to compare different time ranges, queries, and data sources side by side.
Explore Logs: Switch from metrics to logs while preserving label filters; search through logs or view them in a live stream.
Alerting: Visually define alert rules for important metrics; Grafana continuously evaluates rules and sends notifications to Slack, PagerDuty, VictorOps, and OpsGenie.
Mixed Data Sources: Supports mixing different data sources in a single graph, specifying a data source on a per-query basis, and works with custom data sources.
Use Cases:
Monitoring infrastructure and application performance by querying and visualizing metrics from various storage backends.
Troubleshooting incidents by exploring logs alongside metrics with preserved label filters.
Building operational dashboards for teams to share real-time status and historical data.
Setting up automated alerting on key metrics with notifications sent to communication and incident management tools.
Why It Matters:
Grafana provides a self-contained, open-source platform for centralizing observability data from multiple sources without requiring proprietary infrastructure. Its support for mixed data sources and per-query data source selection offers flexibility for teams with diverse monitoring stacks. The platform’s focus on dynamic, template-driven dashboards and integrated alerting reduces the need for separate tools when building a monitoring workflow.
