Overview of Grafana 8 alerts

• Alerting rule - One or more query and/or expression, a condition, the frequency of evaluation, and the (optional) duration that a condition must be met before creating an alert.
• Notification policy - A set of matching and grouping criteria used to determine where, and how frequently, to send notifications.
• Silences - Date and matching criteria used to silence notifications.

You can perform the following tasks for alerts:

• Create a Cortex or Loki managed alert rule
• Add or edit an alert contact point
• Create and edit silences
