Annotating dashboards
Annotations are a versatile mechanism to highlight individual events in a time series. By singling out a single data point at a particular time and marking it with metadata, you have the capability to mark up your dashboard panels with rich data, such as text and tagging. Grafana provides two annotation capabilities to choose from – native annotation queries are created interactively and stored with the dashboard on the Grafana server, while data source annotation queries are created as data source queries, with the query and annotation configuration stored with the dashboard.
