Alerts for synthetic monitoring

In order to provide a unified experience, we're deprecating Synthetics monitor alert notifications and alert conditions violations, and replacing these pages with a new synthetic monitor overview experience in New Relic One. This new experience provides visibility into a monitor's open violations and alert conditions with the monitor results in a single view, removing the need to open multiple tabs to view violations or alert conditions. For more information, check the EoL Announcements page.

If you want to receive alert notifications when a synthetic monitor fails, you can configure the alert notification either while creating a monitor or after you have created one. You can configure your monitor's alert policy directly from the Synthetics UI or via the Alerts UI for existing monitors.

To identify which monitors do not have policies assigned to them, review their color-coded health status.

Add a synthetic monitor to alert policies

A monitor can be included in multiple alert policies. You can view the alert policies and conditions for the selected monitor from the Synthetics UI or from the Alerts UI.

To add an existing monitor to an alert policy:

  1. Go to one.newrelic.com > Alerts & AI > Policies.
  2. From the list of existing alert policies, use the search box or scroll the list to locate one or more alert policies where the monitor has not already been added.
  3. Open the policy, then click Add a condition.
  4. Click Synthetics and then select the monitor.
  5. Fill out the remaining settings and click Create condition.

Existing monitor: Remove from alert policy

To remove an existing monitor from an existing alert policy:

  1. Go to one.newrelic.com > Alerts & AI > Policies.
  2. From the list of existing alert policies, use the search box or scroll the list to locate one or more alert policies where the monitor has not already been added.
  3. Select the trash can (delete) icon on the monitor's row.

Receive alert notifications on a three-strike basis

Synthetic alert notifications operate on a three-strike basis, sending an alert after three monitor attempts from a single location return an error. Your alert policy configuration and notification channel settings will determine when you receive alerts for specific monitors and locations.

If you monitor a non-public app and add your selected public minion IPs to your allow list, you may very infrequently receive a false downtime alert. When a synthetic monitoring data center goes down, New Relic may decide to temporarily use an alternate host, which results in the temporary server's IP being blocked by your app.

Mute (disable) monitor's alert notifications

To temporarily disable alerting for a monitor, mute it:

  1. Go to one.newrelic.com > Synthetics > Monitors > (select a monitor).
  2. Click General under the Settings menu in the left menu sidebar.
  3. Click the Notifications button to Off.

Muting a monitor's alert notifications will not mute multi-location alerts or NRQL alerts.
