Apache Aurora Input Plugin

This plugin gathers metrics from Apache Aurora schedulers. For monitoring recommendations check the Monitoring your Aurora cluster article.

⭐ Telegraf v1.7.0 🏷️ applications, server 💻 all

Global configuration options

Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See CONFIGURATION.md for more details.

Configuration

# Gather metrics from Apache Aurora schedulers
[[inputs.aurora]]
  ## Schedulers are the base addresses of your Aurora Schedulers
  schedulers = ["http://127.0.0.1:8081"]

  ## Set of role types to collect metrics from.
  ##
  ## The scheduler roles are checked each interval by contacting the
  ## scheduler nodes; zookeeper is not contacted.
  # roles = ["leader", "follower"]

  ## Timeout is the max time for total network operations.
  # timeout = "5s"

  ## Username and password are sent using HTTP Basic Auth.
  # username = "username"
  # password = "pa$$word"

  ## 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

Metrics

  • aurora
    • tags:
      • scheduler (URL of scheduler)
      • role (leader or follower)
    • fields:
      • Numeric metrics are collected from the /vars endpoint; string fields are not gathered.

Troubleshooting

Check the Scheduler role, the leader will return a 200 status:

curl -v http://127.0.0.1:8081/leaderhealth

Get available metrics:

curl http://127.0.0.1:8081/vars

Example Output
