description: 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

### 1. Create + verify a Synthetic HTTP check

```bash
# 1. Create the check (full payload in references/synthetic.md)
