Annotate visualizations

Annotations provide a way to mark points on the graph with rich events. When you hover over an annotation you can get event description and event tags. The text field can include links to other systems with more detail.

Native annotations

Grafana comes with a native annotation store and the ability to add annotation events directly from the graph panel or via the [HTTP API]({{< relref "../../../developers/http_api/annotations/" >}}).

Add annotation

1. In the dashboard click on the Time series panel. A context menu will appear.
2. In the context menu click on Add annotation.
3. Add an annotation description and tags(optional).
4. Click save.

Alternatively, to add an annotation, Ctrl/Cmd+Click on the Time series panel and the Add annotation popover will appear

Add region annotation

1. In the dashboard Ctrl/Cmd+click and drag on the Time series panel.
2. Add an annotation description and tags(optional).
3. Click save.

Edit annotation

1. In the dashboard hover over an annotation indicator on the Time series panel.
2. Click on the pencil icon in the annotation tooltip.
3. Modify the description and/or tags.
4. Click save.

Delete annotation

1. In the dashboard hover over an annotation indicator on the Time series panel.
2. Click on the trash icon in the annotation tooltip.

Built-in query

After you added an annotation they will still be visible. This is due to the built in annotation query that exists on all dashboards. This annotation query will fetch all annotation events that originate from the current dashboard and show them on the panel where they were created. This includes alert state history annotations. You can stop annotations from being fetched and drawn by opening the Annotations settings (via Dashboard cogs menu) and modifying the query named Annotations & Alerts (Built-in).

When you copy a dashboard using the Save As feature it will get a new dashboard id so annotations created on source dashboard will no longer be visible on the copy. You can still show them if you add a new Annotation Query and filter by tags. But this only works if the annotations on the source dashboard had tags to filter by.

Query by tag

You can create new queries to fetch annotations from the native annotation store via the -- Grafana -- data source by setting Filter by to Tags.

Grafana v8.1 and later versions also support typeahead of existing tags, provide at least one tag.

For example, create an annotation query name outages and specify a tag outage. This query will show all annotations (from any dashboard or via API) with the outage tag. If multiple tags are defined in an annotation query, then Grafana will only show annotations matching all the tags. To modify the behavior, enable Match any, and Grafana will show annotations that contain any one of the tags you provided.

In Grafana v5.3+ it's possible to use template variables in the tag query. So if you have a dashboard showing stats for different services and a template variable that dictates which services to show, you can now use the same template variable in your annotation query to only show annotations for those services.

Filter by panel

You can configure the panels to which annotations apply by choosing an option from the Show in section. You can select All panels, which applies to all panels that support annotations, or filter for specific panels by choosing Selected panels or All panels except. The annotations are displayed accordingly.

Add time region

When adding or editing an annotation, you can define a repeating time region by setting Query type to Time regions. Then, define the From and To sections with the preferred days of the week and time. You also have the option to change the timezone, which is set to the dashboard's timezone, by default.

{{< figure src="/media/docs/grafana/dashboards/screenshot-annotation-timeregions-10.png" max-width="600px" caption="Time regions business hours" >}}

The above configuration will produce the following result in the Time series panel:

Querying other data sources

Annotation events are fetched via annotation queries. To add a new annotation query to a dashboard open the dashboard settings menu, then select Annotations. This will open the dashboard annotations settings view. To create a new annotation query hit the New button.

{{< figure src="/static/img/docs/v50/annotation_new_query.png" max-width="600px" >}}

Specify a name for the annotation query. This name is given to the toggle (checkbox) that will allow you to enable/disable showing annotation events from this query. For example you might have two annotation queries named Deploys and Outages. The toggle will allow you to decide what annotations to show.

Annotation query details

The annotation query options are different for each data source. For information about annotations in a specific data source, refer to the specific [data source]({{< relref "../../../datasources/" >}}) topic.
