Aurora Input Plugin

The Aurora Input Plugin gathers metrics from Apache Aurora schedulers.

For monitoring recommendations reference Monitoring your Aurora cluster

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 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
