Jolokia2 Proxy Input Plugin

The jolokia2_proxy input plugin reads JMX metrics from one or more targets by interacting with a Jolokia proxy REST endpoint.

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

# Read JMX metrics from a Jolokia REST proxy endpoint
[[inputs.jolokia2_proxy]]
  # default_tag_prefix      = ""
  # default_field_prefix    = ""
  # default_field_separator = "."

  ## Proxy agent
  url = "http://localhost:8080/jolokia"
  # username = ""
  # password = ""
  # response_timeout = "5s"

  ## Optional origin URL to include as a header in the request. Some endpoints
  ## may reject an empty origin.
  # origin = ""

  ## Optional TLS config
  # tls_ca   = "/var/private/ca.pem"
  # tls_cert = "/var/private/client.pem"
  # tls_key  = "/var/private/client-key.pem"
  # insecure_skip_verify = false

  ## Add proxy targets to query
  # default_target_username = ""
  # default_target_password = ""
  [[inputs.jolokia2_proxy.target]]
    url = "service:jmx:rmi:///jndi/rmi://targethost:9999/jmxrmi"
    # username = ""
    # password = ""

  ## Add metrics to read
  [[inputs.jolokia2_proxy.metric]]
    name  = "java_runtime"
    mbean = "java.lang:type=Runtime"
    paths = ["Uptime"]

Optionally, specify TLS options for communicating with proxies:

[[inputs.jolokia2_proxy]]
  url = "https://proxy:8080/jolokia"

  tls_ca   = "/var/private/ca.pem"
  tls_cert = "/var/private/client.pem"
  tls_key  = "/var/private/client-key.pem"
  #insecure_skip_verify = false

  #default_target_username = ""
  #default_target_password = ""
  [[inputs.jolokia2_proxy.target]]
    url = "service:jmx:rmi:///jndi/rmi://targethost:9999/jmxrmi"
    # username = ""
    # password = ""

  [[inputs.jolokia2_proxy.metric]]
    name  = "jvm_runtime"
    mbean = "java.lang:type=Runtime"
    paths = ["Uptime"]

Metric Configuration

Please see Jolokia agent documentation.

Metrics

The metrics depend on the definition(s) in the inputs.jolokia2_proxy.metric section(s).
