# Dovecot Input Plugin

The dovecot plugin uses the dovecot Stats protocol to gather metrics on configured
domains. You can read Dovecot's documentation
[here](http://wiki2.dovecot.org/Statistics)


### Configuration:

```
# Read metrics about dovecot servers
[[inputs.dovecot]]
  ## specify dovecot servers via an address:port list
  ##  e.g.
  ##    localhost:24242
  ##
  ## If no servers are specified, then localhost is used as the host.
  servers = ["localhost:24242"]
  ## Type is one of "user", "domain", "ip", or "global"
  type = "global"
  ## Wildcard matches like "*.com". An empty string "" is same as "*"
  ## If type = "ip" filters should be <IP/network>
  filters = [""]
```
