HTTP and HTTPS monitoring for websites and APIs
✓ HTTP/HTTPS checks ✓ Response status codes ✓ Response time tracking ✓ Redirect validation
Run continuous HTTP monitoring and HTTPS monitoring to verify availability, correct status codes, and performance. Ideal for website monitoring teams that need to catch outages, slow responses, and misconfigured redirects before users do.
Why HTTP/HTTPS monitoring matters
HTTP monitoring is the foundation of modern uptime checks: every probe confirms your endpoint responds, returns the expected HTTP status code, and meets response-time expectations. Pair it with SSL certificate monitoring for end-to-end coverage of HTTPS endpoints.
HTTP status codes
Track 2xx success, 3xx redirects, 4xx client errors, and 5xx server errors—essential for incident response and SEO stability when pages suddenly return the wrong code.
Response time & latency
Measure TTFB and total response time trends to spot degradation early—useful for SLA reporting and performance regressions.
Redirects (301/302)
Validate permanent and temporary redirects during migrations, domain changes, and HTTP-to-HTTPS cutovers.
HTTPS checks + SSL
Combine probes with SSL monitoring to catch certificate expiry and chain issues alongside HTTP failures.
How HTTP/HTTPS monitoring works
UptimeFlux issues HTTP(S) requests on your chosen interval and evaluates each response:
- Availability: did the host respond within the timeout?
- Status code: is it the expected code (200, 301, 404, 500, etc.)?
- Performance: how fast was the response?
- Optional keyword/content checks to detect silent failures (blank pages, error banners).
On failure, trigger downtime alerts through your channels. This complements our broader website monitoring for full-stack visibility.
HTTP response families we track
Group codes to prioritize incidents:
Success (2xx)
200 OK, 201 Created, 204 No Content — healthy responses
Redirects (3xx)
301/302 — validate SEO and migration redirects
Client errors (4xx)
404/403 — missing pages, auth, or routing issues
Server errors (5xx)
500/503 — application or infrastructure failures
