Monitor Varnish Cache servers using Site24x7 plugins and gain in-depth visibility into critical performance metrics.
Varnish Cache is a web application accelarator which is installed in front of an HTTP server to cache the contents. Analyze and optimize your Varnish Cache servers by configuring our plugin. Proactively monitor the availability and performance of caches and work objects created.
This document details how to configure the Varnish Cache plugin and the monitoring metrics for providing in-depth visibility into the performance, availability, and usage stats of Varnish Cache ecosystems.
Varnish Cache performance monitoring metrics:
Install and configure our plugin to monitor the performance metrics of your Varnish Cache ecosystem. Use these key indicators to take informed troubleshooting decisions and ensure continuous functioning of your Varnish Cache:
Use the metric "cache_hit" to record the total number of times the cache was successfully accessed by a request. Helps in understanding the success rate in your system.
Using "cache_miss", metric you can record the total number of times a request was unsuccessful in accessing the cache. Helps in understanding the error rate in your system.
"n_wrk_create" records the total number of worker threads that have been created by various requests in the cache.
Queued work requests
The metric "n_wrk_queued" records the total number of work requests received to the cache that are currently queued.
The metric "sess_pipe_overflow" records the total number of sessions dropped due to session pipe overflow.
