Notes Conrad monitoring General interview questions about monitoring, from your Monitoring note: metrics, logs and traces with the Grafana stack, front-end monitoring and Core Web Vitals, and load testing with k6.
Pages Metrics, logs and traces The three kinds of monitoring data and when to use each, the path from a pod to a Grafana dashboard with Alloy, Loki, Mimir and Tempo, structured logs, Prometheus metric types, exposing metrics from Nitro, percentiles, distributed tracing, and what to alert on. Front-end monitoring Core Web Vitals (LCP, INP, CLS) with their thresholds and fixes, real user monitoring with Grafana Faro versus Lighthouse, sampling and consent, TTFB on a server-rendered site, and tracing a click from the browser to the database. Load testing Load testing a storefront with k6 — smoke, load, stress, spike and soak tests, realistic journeys and URL mixes, thresholds, and what to watch while the test runs.
