Prometheus Monitoring: What It Catches and Misses
Prometheus catches metrics, not whether your site is down from the outside. Learn what Prometheus misses and why external uptime checks complete the picture.
Error Monitoring vs Uptime Monitoring: Why You Need Both
Error tracking (Sentry, Rollbar) catches code exceptions; uptime monitoring catches outages that produce no errors. Why running only one is a blind spot.
Log Monitoring Explained: What Logs Catch and What They Miss
What log monitoring is, what logs catch and what they miss — silent shippers, DNS/CDN outages, third-party deps — and why uptime monitoring completes it.
What Is APM? Application Performance Monitoring Explained
What APM is, what it measures (traces, spans, service maps), when you need it vs when uptime monitoring is enough, and how the two complement each other.
Active vs Passive Monitoring: What's the Difference?
Active vs passive monitoring compared: how synthetic checks and real-traffic observation differ, what each one catches and misses, and why you need both.
Anomaly Detection in Monitoring: Beyond Static Thresholds
What anomaly detection is, how it differs from static thresholds, the techniques behind it, where it helps, and the pitfalls to watch in real monitoring.
Black-Box vs White-Box Monitoring: What's the Difference?
Black-box vs white-box monitoring compared — what each one sees, where each one fails, and why resilient teams run both. A practical guide with examples.
The Four Golden Signals of Monitoring Explained
Latency, traffic, errors, and saturation — what Google's four golden signals mean, why they work, how to measure each one, and how to alert on them.
RED vs USE Method: Monitoring Metrics Frameworks
RED (Rate, Errors, Duration) vs USE (Utilization, Saturation, Errors) — what each method measures, when to use which, and how they fit together.
Latency Percentiles Explained: p50, p95, p99 & p99.9
p99 is the latency your slowest 1% of users hit. Learn why averages hide outages, how to set SLOs on p95 and p99, and how to alert without noise.
OpenTelemetry Monitoring: Traces, Metrics, and Logs
Set up OpenTelemetry monitoring in production. Instrument traces, metrics, and logs, then surface incidents without vendor lock-in.
Observability vs Monitoring: What is the Difference?
Monitoring tells you when something breaks. Observability tells you why. Learn the real difference and how to decide what your team needs.
