Configuring the Prometheus data source

Follow these steps to properly set up Prometheus as a data source:

• URL: Provide the Prometheus service URL, such as https://<XXXXXX>.stackhero-network.com or your custom domain.
• Authentication: Enable Basic Auth, set admin as the username, and provide your Prometheus password. You can find this password in the Stackhero dashboard under the Prometheus service settings.
• Scrape Interval: Ensure the Scrape Interval aligns with your Prometheus server configuration. The default is 15s unless it has been adjusted.

After entering these details, click Save & Test to verify the connection is functional.
