Unlock the Power of Varnishlog: A Comprehensive Tutorial to Gain Actionable Insights from Varnish

Varnish sits in front of the web or application server and caches its output. This means that the logs of the web server no longer paint a complete picture of your site’s traffic. To get a complete view, logging on the edge is needed.

This is why we developed Varnishlog, a powertool to perform in-depth analysis of your requests, responses, backend fetches, backend health and caching behavior–so that you can generate actionable insights to improve performance, reliability, functionality and security.

Varnishlog is more than just a logging tool; it's a comprehensive solution. With its verbose output, tag system, and filtering options, it stands out as a must-have tool for anyone serious about understanding their systems and user interactions.
