You pay your CDN to deliver great service to your users. If
you’re in a large web or media firm, you may be spending
millions of dollars annually on your CDN. So you probably care
about your CDN’s performance. There are quite a few ways in
which you can monitor your CDN. You will already have an APM or
RUM solution in place like AppDynamics, NewRelic, Datadog or
Dynatrace, which helps to understand overall performance, but
can be sorely lacking when you’re trying to troubleshoot network
issues. Why is there higher latency to a specific edge location?
Why did the edge location change suddenly?
ThousandEyes uses active probing to monitor CDN performance,
with broad global visibility and deep insight into specific
network issues that cause performance to fluctuate. You can take
several broad approaches to actively monitor your CDN:
* User to Edge: Monitor the edge to see locations,
network performance and cache utilization. Use Cloud Agents
distributed in customer geographies to target a domain, page or
specific object.
* User to Origin: Monitor the origin to create a baseline
of performance without your CDN, traversing the public Internet.
Again, use Cloud Agents.
* Origin to Edge: Monitor the connection between origin
and edge to ensure proper routing and bandwidth for content
updates and cache misses. Use Enterprise Agents to target the
CDN edge; depending on your CDN configuration you may want to
target specific, proximate edge locations or intermediate load
balancers.
