Grafana Library Elements API
The identifier (ID) of a library element is an auto-incrementing numeric value that is unique per Grafana install. The unique identifier (UID) of a library element uniquely identifies library elements between multiple Grafana installs. It’s automatically generated unless you specify it during library element creation. The UID provides consistent URLs for accessing library elements and when syncing library elements between multiple Grafana installs. The maximum length of a UID is 40 characters.
