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

install with $ python setup.py install or $ pip install vmware_exporter (Installing from pip will install an old version. This is likely something I wont persue)
Create a config.yml file based on the configuration section. Some variables can be passed in 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 using $ vmware_exporter/vmware_exporter.py or you can 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 amd limiting data collection

You do not need to provide a configuration file unless you are not going to use Environment variables. If you do plan to use a configuration file be sure to override the container entrypoint or add -c config.yml to the command args.

If you want to limit the scope of the metrics gather 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
    datastores: True
    hosts: 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
        datastores: True
        hosts: True

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

limited:
    vsphere_host: slowvc.example.com
    vsphere_user: '[email protected]'
    vsphere_password: 'password'
    ignore_ssl: True
    collect_only:
        vms: False
        datastores: True
        hosts: False

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

Environment Variables

Varible	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 collect of hosts
`VSPHERE_COLLECT_DATASTORES`	config, env	True	Set to false to disable collect of datastores
`VSPHERE_COLLECT_VMS`	config, env	True	Set to false to disable collect of virtual machines

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
