Dashboard Auto-refresh settings

by default the fastet auto-refresh interval is 5s. I want to reduce the time, und tried to edit the dashboard settings time option field.
Unfortunately there is no effect if i change the values.

in the settings i wrote this values:
saved the dashboard,
but the GUI still showing defaults (5s / 10s …) ,

What i doing wrong?
Is there a Bug? (7.0.5)

Hi @berndessig2k, there is a setting in grafana.ini file for min_refresh_interval which is set to default 5s. You have to reduce it in grafana.ini file to be able to reduce the interval in dashboard.

Also, more info about grafana.ini file in here - https://grafana.com/docs/grafana/latest/administration/configuration/
