vmware_exporter

VMWare VCenter Exporter for Prometheus.

Get VMWare VCenter information:

• Current number of active snapshots
• Snapshot Unix timestamp creation date
• Datastore size and other stuff
• Basic VM and Host metrics

Usage

• Create a config.yml file based on the config.yml.sample with at least a default section.
• Run $ python vmware_exporter.py
• Go to http://localhost:9272/metrics?target=vcenter.company.com to see metrics

Prometheus configuration

You can use the following parameters in prometheus configuration file. The params section is used to manage multiple login/passwords.

  - job_name: 'vmware_vcenter'
    metrics_path: '/metrics'
    static_configs:
      - targets:
        - 'vcenter.company.com
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: localhost:9272

  - job_name: 'vmware_esx'
    metrics_path: '/metrics'
    file_sd_configs:
      - files:
        - /etc/prometheus/esx.yml
    params:
      section: [esx]
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: localhost:9272
