Alert name is not included in Annotations object, you have to pick it in Labels object.
For example if you use Grafana templating: {{ .Annotations.summary }}: gets the field summary from Annotations {{ .Labels.alertname }}: gets the alert name from Labels
First of all, thanks for your response.
My final goal is to create dashboard with alerts history.
Currently for this purpose i use JSON Api plugin for using grafana/api/annotations as datasource and my panel almost done, except it shows alertID, but not alertName.
If i understand you correctly, i have to find another way to do this, due to that fact that alertName in Annotation object always will be empty string, am i right ?
