Mesos Input Plugin

This input plugin gathers metrics from Mesos. For more information, please check the Mesos Observability Metrics page.

Configuration:

# Telegraf plugin for gathering metrics from N Mesos masters
[[inputs.mesos]]
  ## Timeout, in ms.
  timeout = 100
  ## A list of Mesos masters.
  masters = ["http://localhost:5050"]
  ## Master metrics groups to be collected, by default, all enabled.
  master_collections = [
    "resources",
    "master",
    "system",
    "agents",
    "frameworks",
    "tasks",
    "messages",
    "evqueue",
    "registrar",
  ]
  ## A list of Mesos slaves, default is []
  # slaves = []
  ## Slave metrics groups to be collected, by default, all enabled.
  # slave_collections = [
  #   "resources",
  #   "agent",
  #   "system",
  #   "executors",
  #   "tasks",
  #   "messages",
  # ]

  ## 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

By default this plugin is not configured to gather metrics from mesos. Since a mesos cluster can be deployed in numerous ways it does not provide any default values. User needs to specify master/slave nodes this plugin will gather metrics from.

Tags:

  • All master/slave measurements have the following tags:

    • server (network location of server: host:port)
    • url (URL origin of server: scheme://host:port)
    • role (master/slave)
  • All master measurements have the extra tags:

    • state (leader/follower)
