Status data updating method and device for virtual equipments

Abstract

The invention discloses a status data updating method and a device for virtual equipments. The method comprises the steps that in the current moment, a first snapshot is generated according a preset snapshot model described by a tree structure; according to the depth-first traversal principle of the tree structure, the first snapshot and a second snapshot are compared to obtain a status data incremental set, and the status data incremental set comprises the corresponding nodes and the updating types of the virtual equipments with changed status data in the snapshot module described by the tree structure; and according to the updating type, the status data of the virtual equipments with the changed status data is sequentially updated. According to the status data updating method and the device the virtual equipments, the virtual equipments with changed status data and the updating types of the virtual equipments can be rapidly determined, only the corresponding status data of the virtual equipments with changed status data need to be updated, and the updating of the status data of the virtual equipments still can be rapidly realized when the number of the virtual equipments is increased.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for updating virtual device state data. Background technique [0002] During the routine maintenance of virtual devices in a virtualized environment, the status of virtual devices will change dynamically according to different management platforms or different control methods (automatic and manual) on the same management platform. Provide an active notification mechanism to notify the third-party monitoring platform of the status changes of virtual devices in the virtualization platform. At present, the commonly used monitoring technology method is that the third-party monitoring platform needs to actively poll the virtualization The device status data is read into a high-speed cache at one time, and the monitoring information required in the monitoring system is read from the high-speed cache. [0003] If the status data of the virtual device changes, it i...
