Prometheus

This guide configures Prometheus to stream metrics to Layer 9’s hosted collector via the Prometheus Remote Write protocol.

Prerequisites

• A running Prometheus server
  • Access to its config file (prometheus.yml)
  • Ability to reload Prometheus after config changes
• Outbound internet access to the remote-write URL
  • Firewall allows egress to 443
  • Router/NAT supports outgoing HTTPS
  • Note: Public IP whitelisting available upon request

Step 1: Coordinate with Layer Nine Team

Contact the Layer Nine team to obtain your organization-specific connection details:

• Remote write URL
• Secret Key

Step 2: Add “remote write” config

Update your Prometheus configuration to include the “remote_write” section.

remote_write:
  - url: <REMOTE WRITE URL>
    headers:
      X-Layer9-Secret: <SECRET KEY>
