Description
The aggregator server creates a prometheus registry and pushes metrics via
spawn_metrics_push_job, but never starts an HTTP server to serve/metrics. This means grafana-alloy (which discovers pods viaprometheus.io/scrape: "true"annotations) tries to scrapepod_ip:9184/metricsbut nothing is listening, resulting inup=0.This adds
start_basic_prometheus_server()to bind a prometheus HTTP server on0.0.0.0:9184, matching what the key server already does. Both push and pull metrics now work.Test Plan
