If you are using Proxy, contact Support for the proxy configuration.
Do I need to follow any prerequisites before adding a synthetic monitor?
Yes, the following prerequisites are required before adding a synthetic monitor:
- Whitelist IP addresses for location.
- Assign synthetics template - This is used to initiate synthetic monitoring using Assign Templates or Device Management Policies.
- Set permissions for Device Create, Device Edit, Device View, and Device Manage to create, edit, view, and delete the configured synthetic monitors respectively.
- Verify if your assigned role has access to all resources. Otherwise, you cannot delete a synthetic monitor.
How do I manage accounts for synthetic monitoring?

Can I assign templates to initiate synthetic monitoring?
Yes, synthetic monitoring starts only after assigning the synthetic templates to the monitor. For more information, see Assigning Templates.
What happens if the free RAM in the Synthetic Collector is less than 500MB?
If the available RAM is less than 500MB, the synthetic application will not initiate any requests for that iteration until the available RAM exceeds 500MB to start monitoring. During this time, the collector will not report any monitoring data.
Why there is a difference in certificate validity days between SSL and HTTPS monitoring?
In Synthetics, the number of days for the SSL certificate validity is calculated as part of both HTTPS and SSL synthetic services.
The SSL synthetic resource type is used to monitor the SSL certificate of the configured URL. On the other hand, with the HTTPS synthetic resource type, we monitor the SSL certificate of the end-redirected URL.
It’s important to note that there might be cases where customers observe different validity periods for an HTTPS and SSL synthetic resource, even if they have the same URL configured.
Example; SSL may show 10 days and HTTPS shows 15 days of certificate validity.
How do we check the certificate details?
To check certificate details, use the following curl commands.
For HTTPS synthetic data:
curl -vIL <url> For SSL synthetic data:
curl -vI <url> What we should do, if there is a proxy between the synthetics collector and OpsRamp cloud?
Configure the proxy on the collector using the steps provided in the documentation
OpsRamp Synthetic Service Status Template
What is “OpsRamp Synthetic Service Status” template?
The Synthetic Service Status template is a global template that is automatically applied when the Synthetic Agent is enabled in the Gateway profile, starting with Gateway version 15.0.0.
When is the template assigned or re-assigned?
The global template is automatically assigned when the Synthetic Agent is enabled. If unassigned by the user and the agent is re-enabled, the template will be re-applied.
Can user modify the template?
Yes, customers can clone the global template and assign the customized version to the Gateway. Once a cloned template is assigned, the global template will not be reassigned automatically.
What happens when the Synthetic Agent is re-enabled?
When the Agent is re-enabled, only the global template is applied. If have any cloned templates, it will not be reassigned automatically.
Is the template unassigned when the Synthetic Agent is disabled?
Yes, the Synthetic Service Status template (or any cloned version) is automatically unassigned if the Synthetic Agent is disabled.
Should customers continue using templates with configuration parameters for Synthetics in v2?
No, customers should not use templates with configuration parameters, as all the configuration parameters will be moved directly to the resource in the v2 Synthetics page.
