Site monitoring

Availability, HTTPS certificates, DNS, page-error detection and multi-region speed tests.

• Site management & status meaningsHow to read the site list, what each column means, and what bulk actions can do.
• Add & edit sites — field by fieldWhat every field in the site form means and suggested values; most cases only need name and URL.
• Judgement rules — status code, keywords, response time & DNSWhat a probe round actually checks, what counts as failure, and what DNS verification is.
• Reading the site detail pageTwo charts (48h & 90d), timing breakdown, certificate, incident history — troubleshooting starts here.
• Page error detection — HTTP 200 but the page is actually brokenA normal status code doesn't mean a normal page — failed database connections and framework error pages are recognized.
• HTTPS certificate monitoring & expiry remindershttps sites get their certificate validated on every probe, with staged reminders before expiry; handshake failures are labeled separately.
• Multi-region speed testFire one request from each vantage point and compare reachability and timings across regions.
• Resource check & browser checkPage is 200 but resources 404, JS throws, XHRs fail — these two checks catch the "looks fine" problems.
• Domain ownership verificationSome sensitive operations require proving the domain is yours — via a DNS TXT record or a file upload.
• Bulk-import sitesNo need to create dozens of sites one by one — paste a list or upload a file and import them all at once.
• Groups & trashGroups make filtering and bulk actions easier; deleted sites land in the trash first and can be restored.
