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.

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Gather metrics from the Tomcat server status page.
[[inputs.tomcat]]
  ## URL of the Tomcat server status
  # url = "http://127.0.0.1:8080/manager/status/all?XML=true"

  ## HTTP Basic Auth Credentials
  # username = "tomcat"
  # password = "s3cret"

  ## Request timeout
  # timeout = "5s"

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false
