Prometheus

Connection Requirements

1 - Domain

Host of the Prometheus instance. Do not include the scheme (http:// / https://) — that is controlled by the Is Secure option below.

Prometheus listens on port 9090 by default and exposes its HTTP API directly from the root path (/api/v1/query). If your instance uses the default port, include :9090 in the domain. If Prometheus is served behind a reverse proxy with a path prefix (e.g. /prometheus), append that path to the domain.

Examples:

• prom.example.com:9090 — default Prometheus on its default port

• prom.internal — reverse-proxied on HTTP port 80

• sreprometheus.example.com/prometheus — reverse-proxied under a /prometheus path prefix

2 - Custom Query

A PromQL expression that returns the time-series to project into Domain Inventory.

3 - Is Secure?

Choose this if your connection is going to be over HTTPS (optional, default: False).

4 - Proxy

Proxy URL (optional).

5 - Timeout

The amount of time (in seconds) to wait for API responses. (default: 30)

Authentication

This adapter does not perform any authentication against Prometheus. Ensure the configured endpoint is reachable without credentials (either directly or behind a reverse proxy that handles auth).

Attention

Please perform a connection test to ensure there is a valid connection to the Prometheus API. The connection test executes the custom query against the instance; an invalid query will fail the test. When the discovery operation is finalized you will be able to see the details on Assets page.
