ace-datasource-prometheus
Compile-time Prometheus datasource module for Ace.
Ace keeps the datasource contract and registry in
github.com/aceobservability/ace/backend/pkg/datasource. This module implements
that Client (plus connection test and PromQL metadata). Ace registers the
factory at init and injects its SSRF-safe HTTP client — this module does not
import Ace internal/ packages and does not construct an unpolicy'd client.
Contract
| Surface | Package |
|---|---|
| Query / result types | github.com/aceobservability/ace/backend/pkg/datasource |
| Registry type key | prometheus (Type) |
| Factory | New(url string, httpClient *http.Client) |
httpClient is required. Ace passes ssrf.DatasourceClient wrapped with stored
datasource credentials.
The low-level Prometheus HTTP API client lives in ./promclient (used by Ace's
built-in PROMETHEUS_URL handler as well as this adapter).
Tests
go test ./...
Query and connection tests speak to an httptest fixture. No live Prometheus
is required.

Types ¶
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client implements the Ace Prometheus query datasource.
func New ¶
New constructs a Prometheus datasource client. httpClient is required so Ace can inject DatasourceClient (dial/redirect policy + auth).
func (*Client) HTTPClient ¶
HTTPClient returns the injected HTTP client. Ace SSRF tests inspect policy wiring.
