Varnish Custom Statistics

Varnish Custom Statistics (VCS) is a real-time statistics engine allowing you to aggregate, display and analyze user web traffic.


Varnish Custom Statistics features

VCS is extremely flexible, allowing you to define the grouping of statistics easily using Varnish Configuration Language (VCL). If you can imagine what kind of traffic you want to analyze, VCS can capture the relevant data.

  • VCS can count everything: Supercharging your analytics and insights, VCS can count everything from page popularity and click count, to device type and location, via the unique logging available in Varnish, by assessing the output of every request handled by your Varnish instance. Other examples of statistical data VCS can mine: trending content, articles or products; cache hits and misses; where traffic is coming from; URLs with long load times; URLs with most hits; URLs with the most 50x response code errors; what clients are generating load, etc.
  • Time series API: Make your decisions on the fly with quick and informative real-time analysis enabled by output in a time series API.
  • JSON format data output: VCS output data can easily be integrated into your existing monitoring solutions.
  • No slowdown: VCS will never slow down page rendering or the delivery of your content as no JavaScript is involved.
