Prometheus SD plugin for Swarm

These codes contain a service discovery based on Prometheus 0.17.0 for Swarm v1.1.0 and later. The implementation code can be found in commits.

Prerequisite

Cause Swarm dosen't provide metrics by itself, a CAdvisor service should be running on every masters and nodes. The CAdvisor listening port should be 8070 by default.

Configuration

- job_name: service-swarm
  swarm_sd_configs:
  - masters:
    - 'http://swarm.example.com:8080'

    refresh_interval: 1s
    metrics_port: '8060'

• refresh_interval instructs how often SD plugin retrieve the Swarm node informations.
• metrics_port instructs which port the CAdvisor service is listening on.
• The label policy configurations are the same as Kubernetes SD plugin.
