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 for details of these statistics.

Configuration:

# 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"
