How Do You Monitor CDNs?
CDN performance tests conducted using ThousandEyes Cloud Agents provide deep insights into CDN content delivery, including geographic CDN load balancing, latency, and availability. We monitor the performance of your application, origin, and CDN edge node, so you can quickly pinpoint and diagnose issues that impact a user’s digital experience. Now, you can gain insight into how CDNs will affect application delivery in real-time and perform CDN comparisons across regions and over time with page load, transaction, and HTTP tests that include rich network measurements, Layer 3 path visualization, and BGP route visualizations.
CDN Monitoring: From Users to Edge to Origin
ThousandEyes helps you monitor CDN-fronted services by measuring performance and detecting issues with content delivery. Whether you use one CDN in a single geography, or load balance several around the world, having visibility into edge locations and paths to your origin servers is invaluable for troubleshooting.
CDN Monitoring: From Users’ Location to Edge to Origin
Content Delivery Networks have become a popular way to get applications to end users faster and more reliably.
But many organizations have a hard time understanding how CDNs impact their performance and how to solve issues that arise.
ThousandEyes helps you monitor your CDN frontend services by measuring performance and detecting issues with content delivery.
Whether you use one CDN in a single geography or load balance several around the world, visibility into Edge locations and paths to your origin servers is invaluable for troubleshooting.
ThousandEyes cloud agents are located in over 100 cities around the world and can be used to actively probe your CDN-fronted applications.
These agents collect a variety of metrics depending on your needs.
In Page Load and Transaction Tests, the Waterfall view provides you with object-level information about the domain, provider, file size, and timing.
You can use this to understand where various objects are hosted and their impact on performance.
Use metrics like Throughput and load time to summarize CDN performance at the network level.
To understand how end users are served by various Edge locations, use HTTP tests to observe whether a connection to the Edge is successful and which server responded to the request.
In addition, HTTP Response Headers can provide even more specific diagnostic information.
To solve the issues affecting a specific Edge or the connection between the origin and the Edge, use the Path Visualization View to locate interfaces with loss and links with high latency.
Pinpoint exactly where and why users are impacted, and easily share any one of these views with your CDN provider to speed up the resolution process.
When working with multiple CDNs, you can use DNS or HTTP tests to map the record received by each geographic region and ensure it matches your desired configuration.
In addition to this diagnostic information, easily customize alerts to trigger for specific geographic regions or only for sites hosted by certain CDN.
When it comes time to summarize data for your team or management, use customizable reports that can slice up the data by each layer and metric.
Create one-off reports to understand a specific event or schedule a recurring report for regular updates.
Begin monitoring your CDN-fronted applications and get actionable data within just a few minutes.
