This template allows you to track the activity of your Varnish cache servers.

Varnish is an HTTP accelerator designed for content-heavy dynamic web sites as well as APIs.

You will be able to see the quantity of requests received and transmitted, and know how often the cache has been useful (so as not to overload your web servers).

Alerts let you know if the service has dropped, if the port has changed, or if the server is not operating normally.

This template doesn't need any password, it uses the varnish CLI, and python that is installed by default on most recent linux distros (so no additional package to install).
