Your website keeps a diary: every visit, every error. Reading it turns mysteries into facts. Here is the plain-language skill.
The two diaries - Access log: every request — who asked, for what, when, with what result (the 200/404/500 codes) - Error log: what your CODE complained about — PHP warnings, database hiccups, crashed plugins
What to look for (the useful patterns) 1. A 404 spike on one URL: something links to a page that died — fix or redirect it 2. Repeated POSTs to /wp-login.php from one IP: brute-force in progress — limit login attempts (the security guide covers it) 3. Requests for /wp-config.php, /.env, /phpmyadmin from strangers: automated probing — normal background noise, your server's protections answer it; a spike means scan for vulnerabilities 4. Traffic from one IP at superhuman speed: a scraper or attacker — support can throttle/block 5. Error-log repeats of one PHP warning: a plugin misbehaving — the usual suspect before any slowdown
What to ignore (the noise) Individual 404s from random bots probing old URLs. Single scan attempts that fail. One-off warnings. Logs are noisy by nature — patterns matter, lines do not.
The 5-minute monthly glance Sort access log by response code → scan the 404s and 500s. Open the error log → look for repeats. That is the whole ritual — and it catches problems while they are still small.
When to escalate Anything you cannot explain after five minutes: screenshot the pattern, WhatsApp support. The log timestamps + our server-side view resolve it fast — the diary has two readers when needed.
Logs feel technical until you read one. Then they feel like superpowers.
