Method and system for implementing virtual network function performance monitoring

A method for implementing Virtual Network Function (VNF) performance monitoring, comprising:

• receiving, by a VNF Manager (VNFM), a threshold policy of a VNF performance monitoring threshold which is sent by a Network Management (NM) or an Operation Support System (OSS) through a Network Function Virtualization Orchestrator (NFVO);
• acquiring, by the VNFM, related information about virtual resources after the VNF is scaled up/down;
• and
• setting, by the VNFM, a new performance monitoring threshold for the VNF according to the threshold policy and the related information about virtual resources after the VNF is scaled up/down, wherein the performance monitoring threshold comprises at least one of a scale up/down threshold and a performance warning threshold.

An Element Management (EM) system, comprising:

• a first interface component to perform information interaction with a Network Management (NM) or an Operation Support System (OSS), comprising:
• receiving a threshold policy of a Virtual Network Function (VNF) performance monitoring threshold sent by the NM or the OSS;
• a second interface component to perform information interaction with the VNF;
• a third interface component to perform information interaction with a VNF Manager (VNFM);
• a threshold setting component to set a new performance monitoring threshold for the VNF according to the threshold policy and related information about virtual resources after the VNF is scaled up/down which is acquired from the second interface component or the third interface component, wherein the performance monitoring threshold comprises at least one of a scale up/down threshold and a performance warning threshold.
