Alerts allow you to be notified when a metric is outside of a certain range. You can set up alerts for specific metrics, and add related Lighthouse Monitors you want to be notified about.
You can choose between two types of alerts:
Email alerts will send you an email when the alert is triggered. You can choose any email address you want to receive the alert, this is not limited to the email address you used to sign up.
To get started, you need to create a Slack Incoming Webhook. Slack alerts will send you a message into a Slack channel that you've selected upon creation.
You can choose between three conditions for alerts:
Degraded means that the metric is getting lower/worser compared to the current datapoint. This condition takes the current average into account to keep notifications to a minimum.
Below means that the metric is below a certain value. Once the current datapoint is below the specified value, you will be notified. To minimize notifications, this condition takes the current average into account.
Above means that the metric is above a certain value. Once the current datapoint is above the specified value, you will be notified. To minimize notifications, this condition takes the current average into account.
