# 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.
|
|
|
