CDN Monitoring for Edge Caching & Performance
Confirm your content is actually served from the CDN edge — not silently falling back to your origin. Inspect cache headers, measure edge response times from regions around the world, and get alerted the moment caching breaks.
Comprehensive CDN Monitoring Features
Everything you need to keep your edge fast and your cache warm
Cache HIT / MISS Detection
We read the cache-status headers on every check to confirm whether your content was served from the edge cache or fetched fresh from origin.
Origin Fallback Alerts
A misconfigured CDN silently serves from your origin, slowing users and spiking load. We catch that fallback and alert you before it costs you.
Global Edge Measurement
Check your CDN from multiple regions worldwide to measure real edge performance from where your users actually are, not just one location.
Edge Response Times
Track time-to-first-byte and full response time from each region so you can spot a slow edge or degrading PoP before users feel it.
Cache Header Inspection
Validate Cache-Control, Age, ETag, and CDN-specific headers to confirm your caching rules and TTLs are configured exactly as intended.
Edge Node Verification
Confirm the correct edge nodes and PoPs are answering by checking the CDN's served-by and ray identifiers on every request.
Smart Alerting
Get notified within seconds when cache hits drop, edge latency climbs, or content stops serving from the CDN, via email, Slack, Discord, and webhooks.
Historical Trends
Review cache behaviour and edge latency over time with clear graphs and reports, ideal for tuning TTLs and proving delivery performance.
Why Choose Our CDN Monitoring Solution?
A CDN only helps when it's actually caching — and a single misconfigured rule can quietly route every request back to your origin. Our CDN monitoring runs from global probe locations, reads the real cache and edge headers on each check, and measures response times from the regions your users live in. You get an early-warning system for cache misses, origin fallback, and slow edge performance, around the clock.

How CDN Monitoring Works
Simple setup, complete edge visibility
Add Your Asset URL
Enter the URL of a cacheable asset behind your CDN and choose the regions you want to check it from.
Set Expectations
Define what a healthy response looks like — cache hits, acceptable edge latency, and how many regions must agree before an alert fires.
Monitor 24/7
Our global network requests your asset continuously, recording cache status, response time, and the edge node that answered from every location.
Get Instant Alerts
When caching breaks or the edge slows down, you get immediate notifications and a detailed incident timeline showing which regions failed.
CDN Monitoring Use Cases
Perfect for any content delivered from the edge
Cache Configuration Validation
Confirm new caching rules and TTL changes behave as intended after every deploy. Catch a rule that accidentally disables caching before it sends your traffic back to origin.
Origin Load Protection
Detect silent origin fallback the instant it starts. Keep your origin servers shielded from traffic floods that a misconfigured cache would otherwise unleash.
Global Performance Assurance
Measure edge response times from the regions your audience lives in. Spot a slow or degraded PoP so a regional slowdown never quietly hurts your users.
Static Asset & Media Delivery
Keep images, scripts, stylesheets, and video segments serving fast from the edge. Verify large media files stay cached and download quickly worldwide.
