Looker admins can manage alerts created by all users on the Alerts management admin page, which can be accessed from the Alerts & Schedules section of the Admin panel. The Alerts management admin page lists information about all active and inactive alerts.

Admins can also see alerts that they have created or followed, or for which they are listed as a recipient, on the Manage Alerts user page. Users with other alerts permissions can manage the alerts they have created and followed from the Manage Alerts user page.

Alert information

The Manage Alerts admin page provides information about all alerts on the Looker instance. Admins and users who have been granted the see_alerts permission can view these settings in the Manage Alerts admin page table:

If a user deletes the dashboard or dashboard tile that the alert is on, that alert will be disabled: Any followers or recipients will no longer receive notifications when the alert conditions are met. On this page, the name of the dashboard will be deleted immediately for the alert. After the next time the alert query runs, the status will show as Disabled with a tooltip message indicating that the dashboard or dashboard element (tile) has been deleted. An admin can then permanently delete the alert from the three-dot menu that is to the right of the alert.

Filtering alerts

To filter the list of alerts, click the filter icon at the top of the alert list:

You can filter alerts by:

• Frequency — The frequency at which the alert is checked for whether conditions have been met or exceeded
  • Minutes — Returns all alerts with a frequency of 15 minutes or 30 minutes
  • Hourly — Returns all alerts with a frequency of Hour, 2 hours, 3 hours, 4 hours, 6 hours, 8 hours, or 12 hours
  • Daily — Returns all alerts with a Daily frequency of any Time
  • Weekly — Returns all alerts with a Weekly frequency of any Day or Time
  • Monthly — Returns all alerts with a Monthly frequency of any Day or Time
• Condition Met — Indicates whether the alert conditions were met when the alert query was last run
  • Yes — Alert conditions were met or exceeded
  • No — Alert conditions were not met or exceeded
• Status — Indicates whether the alert is still being checked against its conditions
  • Active — Alert is still being checked against its conditions
  • Disabled — Alert is no longer being checked against its conditions

You can impose multiple filters on your results. To delete a filter, click the x next to the filter name. Refreshing the browser will also delete all selected filters.

Grouping alerts

Click the icon in the top right of the list to open the Group By menu, and then select an option:

• Default: No grouping.
• Dashboard Names: Group the list by the name of the dashboard on which the alert is set, in alphabetical order.
• Owner: Group the list by alert owner, in alphabetical order.

Alert error and warning messages

The Manage Alerts admin page displays any errors or warnings that are surfaced when the alert query is run or the alert notification is delivered. Error messages, if applicable, appear when you hover over the warning icon or error icon in the Condition Met column:

For alerts that are set up to deliver notifications to the Slack or Slack Attachment (API Token) integrations, the error message Notification delivery failed with existing configuration appears when the alert query determines that the alert conditions have been met but the notification could not be delivered. This failure may occur if something about the Slack configuration has changed since the alert was created — for example, if the Slack workspace that the alert was delivering to was disconnected from the Looker instance or if the Slack channel that the alert was delivering to was deleted, or if Looker cannot connect to the integrations.

Warning: Querying fresh data

A warning icon in the Condition Met column indicates that the data on the dashboard tile upon which the alert is based did not change between the two most recent alert queries. Hovering over this icon displays the message Stale Alert Warning and this text:

The data for this tile did not change between the two most recent alert queries. Verify that the caching policies defined for this dashboard tile are aligned with the alert frequency.

There are a few possible explanations for why the data did not change between queries. If this warning persists, talk to your Looker admin or developer to verify that the caching policies that are defined for this dashboard tile are aligned with the alert frequency setting.

Following alerts

The Following column shows clickable Unfollow and Follow buttons and unclickable Follow buttons.

You will see an Unfollow button next to the alert if you are following the alert. If you click Unfollow, you will stop receiving notifications when this alert is triggered. After you click Unfollow:

• If you own the alert, you will see a Follow button in this column.
• If you do not own the alert, this alert will be removed from this page once you refresh your browser.
• If you were listed as a recipient for an alert’s notifications but did not follow the alert from the alert view window, you will see an unclickable Follow button. To unfollow the alert, you must unsubscribe directly from your alert notification.

You will see an unclickable Follow button next to the alert if any of these conditions are true:

• You own the alert but it is unfollowable.
• You were listed as an email recipient for the alert notifications but did not follow the alert from the alert view window. To unfollow the alert, you must unsubscribe directly from your alert notification.
• The alert is configured to send notifications to Slack.

Alert management options

To the right of each alert is a three-dot menu with these options:

• View Alert
• Edit Alert
• Disable Alert (if the alert is currently enabled)
• Enable Alert (if the alert is currently disabled)

Click View Alert to open the Alert Details page.

Click Edit Alert to open the alert window where you can modify the alert’s settings. Click Save Alert to save changes or Cancel to close the alert window without saving.

If a user deletes the dashboard or dashboard tile that the alert is on, that alert will be disabled: Any followers or recipients will no longer receive notifications when the alert conditions are met. On this page, the alert owner will see immediately that the name of the dashboard has been deleted for the alert. After the next time the alert query runs, the alert Status will show as Disabled.

Alert Details page

The Alert Details page is a pop-up that shows a summary of alert information, which is configured by the alert owner. Alert owners and followers experience a different view of this page.

You can open the Alert Details page in one of these ways:

1. Clicking the three-dot menu to the right of the alert and selecting View Alert
2. Clicking the alert title

Configuring the Alert Details page

After you’ve created an alert, an entry for that alert appears on the Manage Alerts admin page. Open the Alert Details page to configure the information about the alert that its followers and recipients can view:

1. Click in the text box to add context about what conditions trigger your alert or what it means for an alert to be triggered. Click Save to save your description.
2. Click the + Link Investigative Dashboard button.

3. In the Link Dashboard to Alert window, select the folder that contains the dashboard and then click on the name of the dashboard.

   The name of the linked dashboard will appear in place of the + Link Investigative Dashboard button. Click the button to navigate to the linked dashboard. You can delete the linked dashboard by clicking the x in the dashboard name — Looker will ask you to confirm that you want to delete the link to the dashboard.

Some alert details display automatically on the Alert Details page and cannot be configured:

• Information about the alert’s history (noted in the Activity tab of the page)
• The alert visualization
• The dashboard synchronization status and name of the dashboard with which the alert is associated

Other ways to interact with an alert you own include:

• Click the three-dot menu on the alert visualization, and then click Explore from here to open an Explore that is pre-set with the query for the dashboard tile on which the alert is set.
• Click the Test Now button to run an instant alert query — if the alert is triggered, a notification will be sent to its owner, recipients, and followers.

Click Done to close the Alert Details page.

Viewing the Alert Details page

You can view the Alert Details for an alert that you do not own if you’re listed as a recipient for that alert or if you have chosen to follow the alert. Open the Details tab on the Alerts Detail page to view the information about an alert that its owner has configured:

1. View context about what conditions trigger your alert or what it means for an alert to be triggered.
2. Click on the linked dashboard to navigate to another dashboard that may add context to the alert query.
3. View the alert visualization.
4. View alert synchronization status.
5. Click the three-dot menu on the alert visualization, and then click Explore from here to open an Explore that is pre-set with the query for the dashboard tile on which the alert is set.
6. Click the Test Now button to run an instant alert query — if the alert is triggered, a notification will be sent to its owner, recipients, and followers.
7. Click Done to close the Alert Details page.

Viewing alert activity

Looker runs an alert query at its specified frequency to check whether data has met or exceeded alert conditions. The results of these checks become the alert’s history. You can click on the Activity tab at the top of the Alert Details page to view the alert’s history as well as additional information:

1. View the frequency with which the alert is checked against its conditions.
2. View alert metadata.
3. View alert synchronization status.
4. Click the Test Now button to run an instant alert query — if the alert is triggered, a notification will be sent to its owner, recipients, and followers.
5. Click Done to close the Alert Details page.

Viewing alert metadata

The table on the Activity tab of the Alert Details page includes metadata about each alert run.

Viewing alert synchronization status

Both tabs on the Alert Details page show the alert’s synchronization status and the name of the dashboard with which the alert is associated:

• A green encircled check mark indicates that the alert is still synced to its dashboard.
• A yellow triangular warning symbol indicates that the alert has become unsynced from its dashboard. The status includes a timestamp of when the synchronization was broken. An unsynced alert displays a None value in the Dashboard column. For information about resolving an unsynced alert, see the Effect of dashboard edits on alerts documentation page.
