Do you mean: (1) prometheus making outbound scrapes using OAuth2 to authenticate itself to exporters? or (2) using OAuth2 to control inbound access to prometheus' own web interface and/or API?
Case (1) has been available since prometheus 2.27.0, using the client credentials grant only. See https://prometheus.io/docs/prometheus/latest/configuration/configuration/#oauth2 As far as I know case (2) isn't implemented natively, but it's done simply by sticking a reverse-proxy in front of Prometheus. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
