This document describes how to manage your synthetic monitors. You can view a list of your synthetic monitors, and for each synthetic monitor, you can view and modify the configuration, view the execution history, and view details about each execution. You can manage your synthetic monitors by using the Google Cloud console or by using the Cloud Monitoring API.
For information about how to explore the execution results and the metrics and logs for a synthetic monitor, see Explore synthetic monitor results.
Before you begin
-
To get the permissions that you need to view and modify synthetic monitors by using the Google Cloud console, ask your administrator to grant you the following IAM roles on your project:
-
Monitoring Editor (
roles/monitoring.editor
) -
Cloud Functions Developer (
roles/cloudfunctions.developer
)
For more information about granting roles, see Manage access to projects, folders, and organizations.
You might also be able to get the required permissions through custom roles or other predefined roles.

The API instructions on this page are for the APIs Explorer. However, you can also issue a curl command. The APIs Explorer provides the curl syntax.
List synthetic monitors
Console
To list the synthetic monitors in your Google Cloud project, do the following:
-
In the Google Cloud console, go to the Synthetic monitoring page:
If you use the search bar to find this page, then select the result whose subheading is Monitoring.
Optional: To restrict which synthetic monitors are listed, add filters.
Each filter is composed of a name and a value. You can set the value to be an exact match for an synthetic monitor name or a partial match. Matches aren't case sensitive. For example, to list all synthetic monitors whose name contains
default
, do the following:- Click Filter table and select Display name.
- Enter
default
and then press the return key.
If you have multiple filters, then the filters are automatically joined by a logical
AND
unless you insert anOR
filter. The previous example uses theOR
filter so that an uptime check is listed if its name matchesdefault
orTesting check
.
The Synthetic monitors page displays the following for each synthetic monitor:
- Status of the most recent execution.
- A link to detailed information about that synthetic monitor.
- The success rate and average execution time.
- The number of alerting policies.
- To edit, copy, or delete the synthetic monitor, and to create an alerting policy, use the more_vert More options menu.
