-# Varnish Cache collector
-
-Provides HTTP accelerator global, Backends (VBE) and Storages (SMF, SMA, MSE) statistics using `varnishstat` tool.
-
-Note that both, Varnish-Cache (free and open source) and Varnish-Plus (Commercial/Enterprise version), are supported.
-
-## Requirements
-
-- `netdata` user must be a member of the `varnish` group
-
-## Charts
-
-This module produces the following charts:
-
-- Connections Statistics in `connections/s`
-- Client Requests in `requests/s`
-- All History Hit Rate Ratio in `percent`
-- Current Poll Hit Rate Ratio in `percent`
-- Expired Objects in `expired/s`
-- Least Recently Used Nuked Objects in `nuked/s`
-- Number Of Threads In All Pools in `pools`
-- Threads Statistics in `threads/s`
-- Current Queue Length in `requests`
-- Backend Connections Statistics in `connections/s`
-- Requests To The Backend in `requests/s`
-- ESI Statistics in `problems/s`
-- Memory Usage in `MiB`
-- Uptime in `seconds`
-
-For every backend (VBE):
-
-- Backend Response Statistics in `kilobits/s`
-
-For every storage (SMF, SMA, or MSE):
-
-- Storage Usage in `KiB`
-- Storage Allocated Objects
-
-## Configuration
-
-Edit the `python.d/varnish.conf` configuration file using `edit-config` from the Netdata [config
-directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md), which is typically at `/etc/netdata`.
-
-```bash
-cd /etc/netdata # Replace this path with your Netdata config directory, if different
-sudo ./edit-config python.d/varnish.conf
-```
-
-Only one parameter is supported:
-
-```yaml
-instance_name: 'name'
-```
-
-The name of the `varnishd` instance to get logs from. If not specified, the host name is used.
-
-
-
-
-### Troubleshooting
-
-To troubleshoot issues with the `varnish` module, run the `python.d.plugin` with the debug option enabled. The
-output will give you the output of the data collection job or error messages on why the collector isn't working.
-
-First, navigate to your plugins directory, usually they are located under `/usr/libexec/netdata/plugins.d/`. If that's
-not the case on your system, open `netdata.conf` and look for the setting `plugins directory`. Once you're in the
-plugin's directory, switch to the `netdata` user.
-
-```bash
-cd /usr/libexec/netdata/plugins.d/
-sudo su -s /bin/bash netdata
-```
-
-Now you can manually run the `varnish` module in debug mode:
-
-```bash
-./python.d.plugin varnish debug trace
-```
