# Varnish Input Plugin
This plugin gathers stats from [Varnish HTTP Cache](https://varnish-cache.org/)
### Configuration:
```toml
# A plugin to collect stats from Varnish HTTP Cache
[[inputs.varnish]]
## The default location of the varnishstat binary can be overridden with:
binary = "/usr/bin/varnishstat"
## By default, telegraf gathers stats for 3 metric points.
## Setting stats will override the defaults shown below.
## stats may also be set to ["all"], which will collect all stats
stats = ["MAIN.cache_hit", "MAIN.cache_miss", "MAIN.uptime"]
```
### Measurements & Fields:

MEMPOOL, etc). In the output, the prefix will be used as a tag, and removed from field names.

### Tags:
As indicated above, the prefix of a varnish stat will be used as it's 'section' tag. So section tag may have one of
the following values:
- section:
- MAIN
- MGT
- MEMPOOL
- SMA
- VBE
- LCK
### Example Output:
```
telegraf -test -config etc/telegraf.conf -input-filter varnish
* Plugin: varnish, Collection 1
> varnish,host=rpercy-VirtualBox,section=MAIN cache_hit=0i,cache_miss=0i,uptime=8416i 1462765437090957980
