See the docs [here](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#url-format) I think you could test if cluster by calling: ${url}:8481/admin/tenants the flags url would be: ${url}:8481/flags and query for ${tenant} (the default is 0) would be: ${url}:8481/select/${tenant}/prometheus/api/v1/query?query=example My current workaround is to set: prometheus_url: http://vmselect-k8s-victoria-metrics-k8s-stack.monitoring.svc.cluster.local:8481/select/0/prometheus
