Instance Method Details

#list(opts = {}) ⇒ Array<Statistic>

Retrieves a list of statistics.

For example, to retrieve the statistics for virtual machine 123 send a request like this:

GET /ovirt-engine/api/vms/123/statistics

The result will be like this:

<statistics>
  <statistic href="/ovirt-engine/api/vms/123/statistics/456" id="456">
    <name>memory.installed</name>
    <description>Total memory configured</description>
    <kind>gauge</kind>
    <type>integer</type>
    <unit>bytes</unit>
    <values>
      <value>
        <datum>1073741824</datum>
      </value>
    </values>
    <vm href="/ovirt-engine/api/vms/123" id="123"/>
  </statistic>
  ...
</statistics>

Just a single part of the statistics can be retrieved by specifying its id at the end of the URI. That means:

GET /ovirt-engine/api/vms/123/statistics/456

Outputs:

<statistic href="/ovirt-engine/api/vms/123/statistics/456" id="456">
  <name>memory.installed</name>
  <description>Total memory configured</description>
  <kind>gauge</kind>
  <type>integer</type>
  <unit>bytes</unit>
  <values>
    <value>
      <datum>1073741824</datum>
    </value>
  </values>
  <vm href="/ovirt-engine/api/vms/123" id="123"/>
</statistic>

  • opts (Hash) (defaults to: {})
