Elasticsearch annotations

Annotations overlay event data on your dashboard graphs, helping you correlate log events with metrics. You can use Elasticsearch as a data source for annotations to display events such as deployments, alerts, or other significant occurrences on your visualizations.

For general information about annotations, refer to Annotate visualizations.

Before you begin

Before creating Elasticsearch annotations, ensure you have:

• An Elasticsearch data source configured in Grafana
• Documents in Elasticsearch containing event data with timestamp fields
• Read access to the Elasticsearch index containing your events

Create an annotation query

To add an Elasticsearch annotation to your dashboard:

1. Navigate to your dashboard and click Dashboard settings (gear icon).
2. Select Annotations in the left menu.
3. Click Add annotation query.
4. Enter a Name for the annotation.
5. Select your Elasticsearch data source from the Data source drop-down.
6. Configure the annotation query and field mappings.
7. Click Save dashboard.

Query

Use the query field to filter which Elasticsearch documents appear as annotations. The query uses Lucene query syntax.

Examples:

Query	Description
*	Matches all documents.
type:deployment	Shows only deployment events.
level:error OR level:critical	Shows error and critical events.
service:api AND environment:production	Shows events for a specific service and environment.
tags:release	Shows events tagged as releases.

You can use template variables in your annotation queries. For example, service:$service filters annotations based on the selected service variable.

Field mappings

Field mappings tell Grafana which Elasticsearch fields contain the annotation data.

Time

The Time field specifies which field contains the annotation timestamp.

• Default: @timestamp
• Format: The field must contain a date value that Elasticsearch recognizes.

Time End

The Time End field specifies a field containing the end time for range annotations. Range annotations display as a shaded region on the graph instead of a single vertical line.

• Default: Empty (single-point annotations)
• Use case: Display maintenance windows, incidents, or any event with a duration.

Text

The Text field specifies which field contains the annotation description displayed when you hover over the annotation.

• Default: tags
• Tip: Use a descriptive field like message, description, or summary.

Tags

The Tags field specifies which field contains tags for the annotation. Tags help categorize and filter annotations.

• Default: Empty
• Format: The field can contain either a comma-separated string or an array of strings.

Example: Deployment annotations

To display deployment events as annotations:

1. Create an annotation query with the following settings:
   • Query: type:deployment
   • Time: @timestamp
   • Text: message
   • Tags: environment

This configuration displays deployment events with their messages as the annotation text and environments as tags.

Example: Range annotations for incidents

To display incidents with duration:

1. Create an annotation query with the following settings:
   • Query: type:incident
   • Time: start_time
   • Time End: end_time
   • Text: description
   • Tags: severity

This configuration displays incidents as shaded regions from their start time to end time.
