Checklist & Cheat Sheet
Treat this page as a copy/paste reference. Focus on trends and baselines, not one-size-fits-all thresholds.
Routine
Daily (2 minutes)
- Check errors and cache status shifts at the edge (Cloudflare).
- Check origin pressure (CPU/RAM/disk) if you saw errors or latency.
Weekly (15 minutes)
- Review CWV field trends (Cloudflare RUM and/or Search Console).
- Review slow queries and error logs.
- Pick 1-3 regressions to fix, then re-baseline.
Commands
Origin quick snapshot
uptime
free -m
df -h /
ps aux --sort=-%cpu | head -10
ps aux --sort=-%mem | head -10
Cache headers (CDN and origin)
curl -sI https://example.com/ | grep -iE 'cf-cache-status|x-litespeed-cache|x-cache|cache-control'
Services and logs (common stacks)
sudo systemctl status lsws nginx php8.2-fpm lsphp82 mariadb redis-server 2>/dev/null || true
sudo tail -50 /usr/local/lsws/logs/error.log 2>/dev/null || true
sudo tail -50 /var/log/nginx/error.log 2>/dev/null || true
sudo tail -50 /var/log/mysql/error.log 2>/dev/null || true
Checklist
- Baseline exists for representative URLs.
- Uptime monitoring exists with actionable alerts.
- Field data is reviewed regularly (RUM/CrUX).
- Load tests are run after major infrastructure changes.
- Profiling is available for "why is it slow" investigations.
