Grafana: Open-source monitoring and observability platform
Query and visualize metrics from multiple data sources.
Learn more about Grafana
Grafana is a web-based observability platform written in Go that aggregates data from various time-series databases and log storage systems. It uses a plugin architecture to support multiple data sources including Prometheus, Loki, Elasticsearch, InfluxDB, and PostgreSQL, allowing queries to be executed against heterogeneous backends. The platform includes features for creating templated dashboards, defining alert rules with visual editors, and exploring metrics and logs through ad-hoc queries. Deployments typically run as a containerized service in monitoring stacks, serving as a central visualization layer for infrastructure and application observability.
Multi-source data mixing
Supports querying and combining data from different data sources within a single dashboard or panel, with data source selection available on a per-query basis. This includes custom datasources through the plugin system.
Plugin-based extensibility
Uses a plugin architecture for data sources, panels, and applications, allowing third-party extensions without modifying core code. The ecosystem includes community and vendor-maintained plugins for various backends and visualization types.
Integrated alerting and exploration
Combines metrics visualization, log exploration, and alert rule definition in a single interface. Features include preserved label filtering when switching between metrics and logs, and split-view comparisons of different time ranges and queries.
import { DataSourceApi } from '@grafana/data';
import { getDataSourceSrv } from '@grafana/runtime';
const ds = await getDataSourceSrv().get('Prometheus');
const result = await ds.query({
targets: [{ expr: 'up', refId: 'A' }],
range: { from: 'now-1h', to: 'now' }
});
console.log(result.data);Grafana v12.3.2 delivers security improvements, bug fixes for alerting race conditions, and enhancements to avatar handling and Elasticsearch annotations.
