Content Delivery Networks (CDNs) have become essential for modern IT architecture by reducing latency and improving website performance through the geographically distributed caching of rich content. To effectively monitor CDNs, it's crucial to choose a robust tool that can analyze CDN logs, track key performance indicators, and provide security monitoring by detecting anomalies like breaches with minimal delay. Tools such as Coralogix offer full-stack observability with a pricing model that charges based on analysis rather than data size, making them cost-effective despite the large volume of CDN logs. They offer both static and dynamic alerting systems to promptly inform IT teams of any performance or security issues, ensuring a quick response. Additionally, the ability to query archived logs helps in assessing performance changes over time, holding CDN providers accountable, and ensuring adherence to service level agreements.
