What is Varnish?
Varnish is an HTTP accelerator designed for content-heavy dynamic web sites as well as heavily consumed APIs.
Monitor your Varnish Cache performance
With Dynatrace, system performance metrics (CPU, memory, and more) are available when using OneAgent on a server running Dynatrace OneAgent. When problems are detected, the Dynatrace anomaly-detection engine correlates host and network metrics with web-server specific metrics to identify the root causes.
You also get network-related details. Dynatrace shows you all relevant information in an interactive infographic.
Advanced Varnish Cache metrics
With an additional Python script, advanced metrics from Varnish Cache servers are available. Dynatrace shows you:
- Cache performance
- Backend metrics
- Client metrics
- Thread metrics
See the Monitor Varnish Cache Guide to learn how to integrate Varnish Cache metrics into your Dynatrace environment.
