Public probes

In Grafana Cloud Synthetic Monitoring, probes are the monitoring agents responsible for simulating user interactions with your web applications or services. These agents periodically send requests to predefined URLs and record the responses, checking for expected outcomes and measuring performance.

Grafana Labs operates public probes distributed in various geographical locations to simulate user traffic from different regions. That helps identify and analyze potential performance and availability issues that might be specific to certain locations. You can choose from public probes in AMER, EMEA, and APAC.

You can also set up Private probes in Synthetic Monitoring.

If you need to allow access through your firewall, refer to source IP addresses for allow-listing.

You can find a list of public probes and your private probes by going to Testing & synthetics > Synthetics > Probes.

The following is a list of available probes across Synthetic Monitoring by region, as well as the cloud provider it uses and any feature limitations.
