# Tomcat Input Plugin

The Tomcat plugin collects statistics available from the tomcat manager status page from the `http://<host>/manager/status/all?XML=true URL.`
(`XML=true` will return only xml data). See the [Tomcat documentation](https://tomcat.apache.org/tomcat-9.0-doc/manager-howto.html#Server_Status) for details of these statistics.

### Configuration:

```toml
# A Telegraf plugin to collect tomcat metrics.
[[inputs.tomcat]]
  # A Tomcat status URI to gather stats.
  # Default is "http://127.0.0.1:8080/manager/status/all?XML=true".
  url = "http://127.0.0.1:8080/manager/status/all?XML=true"
  # Credentials for status URI.
  # Default is tomcat/s3cret.
  username = "tomcat"
  password = "s3cret"
```
