Class Method Summary

• .is_error?(value) ⇒ Boolean

  Returns true if the object returned by a method of the OpenNebula library is an Error.

• .pool_page_size ⇒ Object
• .process_monitoring(xmldoc, root_elem, timestamp_elem, oid, xpath_expressions) ⇒ Hash<String, Array<Array<int>>, OpenNebula::Error] Hash with the requested xpath expressions, and an Array of [timestamp, value].

  Processes the monitoring data in XML returned by OpenNebula.

.process_monitoring(xmldoc, root_elem, timestamp_elem, oid, xpath_expressions) ⇒ Hash<String, Array<Array<int>>, OpenNebula::Error] Hash with the requested xpath expressions, and an Array of [timestamp, value].

Processes the monitoring data in XML returned by OpenNebula

Parameters:

• xmldoc (XMLElement) —

  monitoring data returned by OpenNebula

• root_elem (String) —

  Root for each individual PoolElement

• timestamp_elem (String) —

  Name of the XML element with the last monitorization timestamp

• oid (Integer) —

  Id of the object to process

• xpath_expressions (Array<String>) —

  Elements to retrieve.

Returns:

• (Hash<String, Array<Array<int>>, OpenNebula::Error] Hash with the requested xpath expressions, and an Array of [timestamp, value].) —

  Hash<String, Array<Array<int>>, OpenNebula::Error] Hash with the requested xpath expressions, and an Array of [timestamp, value].
