Probe, load-test, and instrument frontends from Grafana Cloud. Covers Synthetic Monitoring (HTTP / DNS / TCP / Ping / Traceroute / Multihttp / k6-browser scripted checks from 20+ global probes, alert on \`probe\_success\` + TLS-cert expiry), Grafana Cloud k6 (distributed load tests across AWS load-zones, scenarios, \`http\_req\_duration\` thresholds, CI integration via \`grafana/k6-action\`), and Frontend Observability with Faro Web SDK (RUM, Core Web Vitals, custom events, \`pushError\`, distributed-trace correlation). Use when checking website / API uptime from multiple regions, gating a release on a load test, watching for TLS-cert renewal, instrumenting a React/Vue app, tracking Core Web Vitals, or correlating frontend errors to backend traces — even when the user says "is my login flow up?", "monitor my API", "ping our endpoint every minute", "release-gate load test", "browser performance monitoring", "session replay", or "RUM" without naming Synthetic Monitoring / k6 / Faro.

Grafana Cloud Testing Docs: https://grafana.com/docs/grafana-cloud/testing/ Three pillars: external probing (Synthetic Monitoring), load testing (k6 Cloud), real-user monitoring (Faro). Prerequisites Grafana Cloud stack Synthetic Monitoring: SM access token (sm:write) k6 Cloud: a Grafana Cloud k6 token + projectID Faro: a Faro app + write-token from Frontend Observability → Apps Common Workflows Create + verify a Synthetic HTTP check See references/synthetic.md for all check types, PromQL queries, and alert rules. Run a k6 cloud load test Full script + scenarios + CI YAML: references/k6-and-faro.md.
