Introducing Varnish cache monitoring

We’re happy to announce the public beta release of Varnish cache monitoring for Dynatrace. Varnish Cache is an HTTP accelerator that’s designed for dynamic, content-heavy web sites as well as heavily-consumed APIs. During the public beta release period, you need to manually enable Dynatrace Varnish cache monitoring before you can use it.

To enable Varnish cache monitoring

  1. Go to Settings > Monitoring > Monitored technologies.
  2. On the Supported technologies tab, set the Varnish cache monitoring switch to the On position.

With Varnish cache monitoring enabled, you’ll see the following Varnish-specific metrics on each Varnish process overview page (see example below):

  • Backend metrics
  • Cache performance
  • Client metrics
  • Thread metrics

Service-level insights

You’ll find the new Varnish cache monitoring metrics provided by Dynatrace to be extremely beneficial. As always, Dynatrace provides outstanding service-monitoring visibility. For example, you get service-level visibility into all requests sent to Varnish (see Service flow example below).

PurePath analysis

Dynatrace allows you to track each individual web request from end to end using PurePath technology. You can begin PurePath analysis of any request by clicking one of the View PurePaths buttons (see example above).

User experience monitoring

With Dynatrace Varnish cache monitoring in place, there’s no longer a need to manually configure your Varnish cache to benefit from Dynatrace real user monitoring. Real user monitoring enables you to analyze the user behavior of the applications that call your Varnish cache and use those insights to optimize your application’s customer experience. For full details about Dynatrace user session analysis, please see User session analysis and search enhancements.
