Good monitoring tells you what broke, where, and why\u2014before your customers do.<\/figcaption><\/figure>\n

Most teams have website monitoring. Far fewer have website monitoring that actually catches problems before customers, sales, and support do. The gap is rarely the tool. It is the practices wrapped around it: what gets checked, from where, how often, what triggers a page, and who decides when a check is broken versus when the site is broken.<\/p>\n

This playbook collects eight website monitoring best practices that separate setups SRE and DevOps teams trust from setups that quietly turn into noise. Each one is concrete: thresholds, intervals, anti-patterns, and what to keep doing once it works. The same practices apply whether you are running uptime monitoring on a marketing site or full synthetic transaction monitoring across a SaaS checkout.<\/p>\n

What “Good” Looks Like (and Why Most Setups Miss It)<\/h2>\n

A working definition: your monitoring is good if your team learns about every customer-facing problem from a monitor before they learn about it from a customer, and if the pages you receive are almost always actionable. That is the entire bar.<\/p>\n

Three numbers track it. Mean time to detect (MTTD) tells you whether monitoring is fast enough. Mean time to resolve (MTTR) tells you whether the data the monitor surfaces is enough to fix the problem. Alert precision\u2014the percentage of pages that were real and required immediate action\u2014tells you whether your team will still trust the alerts in six months. Most SRE teams measure MTTD and MTTR. Most teams do not measure precision. That is why so many on-call rotations decay into silent acknowledgments and learned helplessness.<\/p>\n

The rest of this playbook is about pushing both numbers in the right direction at the same time.<\/p>\n

Layer Checks Across the Full Request Path<\/h2>\n

A single HTTPS check is a smoke alarm with one sensor. It tells you something is wrong, not where. When a user types your URL and waits for the page to render, the request passes through at least six layers: DNS resolution<\/a>, TCP handshake, TLS negotiation, HTTP response, asset loading, and client-side rendering of the final view. Each layer fails differently and each has its own root cause.<\/p>\n
