# 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.
