Deleted alert rules still sending email notifications (DatasourceNoData)

Grafana
1

Hello,

I am facing an issue where email notifications are still being sent even though the alert rules were deleted from Grafana.

Environment

  • Grafana version: (Version 11.4.0)

  • OS: Linux (RHEL 8.10)

  • Grafana internal DB: SQLite (/var/lib/grafana/grafana.db)

  • Data source for panels: MySQL

Problem

We had alert rules configured on some panels . After some time we started receiving alert emails with the message DatasourceNoData.

However, we removed the alert rules and even the panels themselves.

Despite this, Grafana keeps sending email notifications every few hours.

What I already checked

  • Deleted alert rules from the panel

  • Deleted the panel itself

  • Restarted Grafana server

  • Checked contact points

  • Created a new contact point and removed the old one

  • Checked notification policies

  • Checked provisioning directory (/etc/grafana/provisioning/alerting) – no alert definitions related to this alert

Hellow @asbabayev please view the alert and silent it.
or
in grafana ini file check the grafana alert configuration it not need commented as well.
or
if you don’t want the panel or dashbrod then stop the exporter, prometheus, metrics not come on grafana.
if no DatasourceNoData problem solve in latest versoin on grafana there is new option when no data you can set it is normal then email not come.
Thanks
