# 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:
|
||
|
|
|
||
|
|
This is the full list of stats provided by varnish. Stats will be grouped by their capitalized prefix (eg MAIN,
|
||
|
|
MEMPOOL, etc). In the output, the prefix will be used as a tag, and removed from field names.
