Author Grafana Cloud Synthetic Monitoring checks, with deep coverage of k6 scripted and browser checks: SM's single-VU/single-iteration execution model, assertions that actually fail probe\_success (expect() and fail() vs bare check()), secrets, deterministic scripts, robust browser locators, local validation with k6 run, deployment via UI/API/Terraform, verifying probe\_success, and rollback. Also helps choose the simplest sufficient check type (HTTP/ping/DNS/TCP, MultiHTTP, scripted, browser). Use when writing a synthetic check, monitoring a login/checkout/signup flow in production, converting a k6 script or an OpenAPI spec into a check, authoring a browser check, validating a user journey, or asking "is my site up from multiple regions". NOT for load, stress, or performance testing — SM runs one iteration per execution; for load tests use the grafana-k6 plugin or Grafana Cloud k6. For the broad Grafana Cloud Testing overview (SM + k6 Cloud + Faro), use the testing skill.

## Install

## From README

Synthetic Monitoring Check Authoring Docs: https://grafana.com/docs/grafana-cloud/testing/synthetic-monitoring/ Broad Grafana Cloud Testing entry point (SM + k6 Cloud + Faro): testing skill. Reliability monitoring, not load testing Synthetic Monitoring (SM) runs k6 as a reliability/availability engine: every check execution runs one iteration with one VU from each selected probe location on a fixed schedule. Success means "the user journey works right now, from this region" — detect outages before your customers do. Do not apply load-testing idioms. There are no VUs to ramp, no stages, no load profiles, no soak/stress/spike phases, and no thresholds over aggregated traffic. Vocabulary: check, probe, execution, uptime, reachability, user journey validation — never "load test", "ramping", or "VUs".
