Grafana 13.3 adds cross-dashboard variables, Notebooks, and first major UI refresh since version 7

Grafana Labs has released version 13.3 of its open-source observability platform, bringing several features aimed at reducing operational overhead and improving collaborative workflows. The headline addition is cross-dashboard variables, which let administrators define a variable once and apply it across multiple dashboards rather than maintaining duplicate copies per dashboard. These shared variables can be scoped globally across an organization or restricted to specific folders, though the feature remains in public preview and requires a feature toggle on self-hosted installations.

The release also debuts Notebooks, a new document type that lets users combine dashboard panels, Explore queries, Grafana Assistant outputs, and manual observations into a single editable, shareable record. This targets incident response and post-mortem workflows by eliminating the need to stitch together screenshots and external documents. Complementing this, Grafana Assistant now supports a planning mode for dashboard creation, generating a structural proposal with panels, visualizations, and layout for user review before commit. The update also delivers the first phase of Grafana's largest visual refresh since version 7, with redesigned themes, revised typography, and updated UI controls.

What changes in Grafana 13.3

• Cross-dashboard variables: Administrators can define variables once and reuse them across multiple dashboards, with global organization-wide or folder-scoped availability; currently in public preview and enabled via grafana.dashboardGlobalVariables feature toggle on self-hosted instances.
• Notebooks: New document type combining dashboard panels, Explore queries, Assistant findings, and observations into editable, searchable, exportable documents for incident documentation and knowledge sharing.
• Grafana Assistant planning mode: Assistant can propose dashboard structure including panels, visualization types, variables, and layout as a read-only preview before user approval, with undo support for multi-panel changes now generally available.
• Visualization enhancements: Panel thresholds support dashboard variables for dynamic threshold adjustment; Sort by transformation handles multiple fields; panel descriptions display as subtitles; cross-filtering extended to Histogram, State timeline, and Status History; panel-specific time settings and comparisons reach general availability.
• Alerting migration: Public preview support for importing existing Prometheus or Mimir Alertmanager configurations including notification routing into Grafana Alerting, reducing manual recreation during migration.

Why it matters

For platform engineering and SRE teams running self-hosted Grafana stacks, the cross-dashboard variables and Alertmanager import path reduce maintenance burden and migration friction in heterogeneous monitoring environments. The Notebooks feature addresses a persistent gap in open-source observability tooling by providing native incident documentation without requiring external wikis or note-taking applications, potentially tightening feedback loops between detection, investigation, and post-mortem review in Linux-based operations workflows.
