Annotations

Annotations provide a way to mark points on the graph with rich events. When you hover over an annotation you can get title, tags, and text information for the event.

Queries

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.

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 toggles will allow you to decide what annotations to show.

Annotation query details

The annotation query options are different for each data source.

  • [Graphite annotation queries]({{< relref "features/datasources/graphite.md#annotations" >}})
  • [Elasticsearch annotation queries]({{< relref "features/datasources/elasticsearch.md#annotations" >}})
  • [InfluxDB annotation queries]({{< relref "features/datasources/influxdb.md#annotations" >}})
  • [Prometheus annotation queries]({{< relref "features/datasources/prometheus.md#annotations" >}})
