# CouchDB Input Plugin
|
|
|
|
The CouchDB plugin gathers metrics of CouchDB using [_stats] endpoint.

|
|
|
### Configuration
|
|
|
|
```toml
|
|
[[inputs.couchdb]]
|

|
|
## Multiple Hosts from which to read CouchDB stats:
|
|
hosts = ["http://localhost:8086/_stats"]
|
|
|
|
## Use HTTP Basic Authentication.
|
|
# basic_username = "telegraf"
|
|
# basic_password = "p@ssw0rd"
|
|
```
