Grafana alert - Time shift not working

  • What Grafana version and what operating system are you using?
    Centos 7 and Grafana 6.7.5 Datasource Elasticsearch 6.8

  • What are you trying to achieve?

Trying to create alert with MAX tps for yesterday that will fire once a day.

  • How are you trying to achieve it?
    Created a dashboard with time shift now-1d/d+2h, that works fine for me

  • What happened?

When trying to create an alert that will evaluate every 24h with

Conditions

WHEN max () OF query (A, 24h, now/d) IS ABOVE 0

I get an error

Alert validation error: time: invalid duration now/d PanelId: 2 DashboardId: 224

  • What did you expect to happen?

For alert to evaluate 24h until start of the current day.

Does alert time reference conditions support time notation like this ? now-1d/d or similar ?
If not, any idea how to achieve this ? To analyze traffic for yesterday and post back max TPS

In the graph I do get correct result with legend table max display, but not able to post that back to the alert.

Thank you in advance.
