VMWare VCenter Exporter for Prometheus

Project description

vmware_exporter

VMware vCenter Exporter for Prometheus.

Get VMware vCenter information:

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

Usage

Requires Python >= 3.6

  • Install with $ python setup.py install or via pip $ pip install vmware_exporter. The docker command below is preferred.
  • Create config.yml based on the configuration section. Some variables can be passed as environment variables
  • Run $ vmware_exporter -c /path/to/your/config
  • Go to http://localhost:9272/metrics?vsphere_host=vcenter.company.com to see metrics

Alternatively, if you don't wish to install the package, run it using $ vmware_exporter/vmware_exporter.py or use the following docker command:

docker run -it --rm  -p 9272:9272 -e VSPHERE_USER=${VSPHERE_USERNAME} -e VSPHERE_PASSWORD=${VSPHERE_PASSWORD} -e VSPHERE_HOST=${VSPHERE_HOST} -e VSPHERE_IGNORE_SSL=True --name vmware_exporter pryorda/vmware_exporter

Configuration and limiting data collection

Only provide a configuration file if enviroment variables are not used. If you do plan to use a configuration file, be sure to override the container entrypoint or add -c config.yml to the command arguments.

If you want to limit the scope of the metrics gathered, you can update the subsystem under collect_only in the config section, e.g. under default, or by using the environment variables:

collect_only:
    vms: False
    vmguests: True
    datastores: True
    hosts: True
    snapshots: True

This would only connect datastores and hosts.

You can have multiple sections for different hosts and the configuration would look like:

default:
    vsphere_host: "vcenter"
    vsphere_user: "user"
    vsphere_password: "password"
    ignore_ssl: False
    collect_only:
        vms: True
        vmguests: True
        datastores: True
        hosts: True
        snapshots: True

esx:
    vsphere_host: vc.example2.com
    vsphere_user: 'root'
    vsphere_password: 'password'
    ignore_ssl: True
    collect_only:
        vms: False
        vmguests: True
        datastores: False
        hosts: True
        snapshots: True

limited:
    vsphere_host: slowvc.example.com
    vsphere_user: 'administrator@vsphere.local'
    vsphere_password: 'password'
    ignore_ssl: True
    collect_only:
        vms: False
        vmguests: False
        datastores: True
        hosts: False
        snapshots: False

Switching sections can be done by adding ?section=limited to the URL.

Environment Variables

Variable Precedence Defaults Description
VSPHERE_HOST config, env, get_param n/a vsphere server to connect to
VSPHERE_USER config, env n/a User for connecting to vsphere
VSPHERE_PASSWORD config, env n/a Password for connecting to vsphere
VSPHERE_IGNORE_SSL config, env False Ignore the ssl cert on the connection to vsphere host
VSPHERE_COLLECT_HOSTS config, env True Set to false to disable collection of host metrics
VSPHERE_COLLECT_DATASTORES config, env True Set to false to disable collection of datastore metrics
VSPHERE_COLLECT_VMS config, env True Set to false to disable collection of virtual machine metrics
VSPHERE_COLLECT_VMGUESTS config, env True Set to false to disable collection of virtual machine guest metrics
VSPHERE_COLLECT_SNAPSHOTS config, env True Set to false to disable collection of snapshot metrics

You can create new sections as well, with very similiar variables. For example, to create a limited section you can set:

Variable Precedence Defaults Description
VSPHERE_LIMITED_HOST config, env, get_param n/a vsphere server to connect to
VSPHERE_LIMITED_USER config, env n/a User for connecting to vsphere
VSPHERE_LIMITED_PASSWORD config, env n/a Password for connecting to vsphere
VSPHERE_LIMITED_IGNORE_SSL config, env False Ignore the ssl cert on the connection to vsphere host
VSPHERE_LIMITED_COLLECT_HOSTS config, env True Set to false to disable collection of host metrics
VSPHERE_LIMITED_COLLECT_DATASTORES config, env True Set to false to disable collection of datastore metrics
VSPHERE_LIMITED_COLLECT_VMS config, env True Set to false to disable collection of virtual machine metrics
VSPHERE_LIMITED_COLLECT_VMGUESTS config, env True Set to false to disable collection of virtual machine guest metrics
VSPHERE_LIMITED_COLLECT_SNAPSHOTS config, env True Set to false to disable collection of snapshot metrics

You need to set at least VSPHERE_SECTIONNAME_USER for the section to be detected.

Prometheus configuration

You can use the following parameters in the 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

# Example of Multiple vCenter usage per #23

- job_name: vmware_export
    metrics_path: /metrics
    static_configs:
    - targets:
      - vcenter01
      - vcenter02
      - vcenter03
    relabel_configs:
    - source_labels: [__address__]
      target_label: __param_target
    - source_labels: [__param_target]
      target_label: instance
    - target_label: __address__
      replacement: exporter_ip:9272
