When a monitor generates an alert, it triggers notifiers based on the assigned notification policy.
Notifiers are the endpoints receiving notifications, including where to deliver alerts and who to notify. You can configure notifiers to send details of the alert to a channel such as email, PagerDuty, or Slack.
Notification policies are rules that determine how to route notifications to notifiers based on signals that trigger from monitors. Teams own notification policies, and assign them either to a specific monitor or set as a default policy for all monitors in a specified collection.
Optionally, you can use signal groups to create groups of notifications. Signal groups determine how to group alerts, which affects how many notifications Chronosphere sends.
To view a history of alerts for a monitor, in the navigation menu select Alerting > Monitors & Signals and then click the Alert history tab for the selected monitor.
