Monitoring method for monitoring performance of cloud host

Abstract

The invention provides a monitoring system and a monitoring method for monitoring performance of a cloud host. The monitoring method comprises the following steps: collecting a virtual resource utilization state of the cloud host by simultaneously using a cloud host Agent module, a calculation node Agent module and a station monitoring module for monitoring to obtain the monitoring data; accessing to a KVM (K Virtual Machine) management program through Libvirt API (Application Program Interface) of the calculation node Agent module and calling the corresponding Libvirt API to browse and obtain all the monitoring data of the cloud host; monitoring the network availability of the cloud host through at least one station monitoring module, and collecting and calculating monitoring data of a cloud platform through at least an alternate manner, and then storing the monitoring data in a database; and alarming and monitoring all the monitoring data through an alarm module according to alarm setting rules which are set by users. Through the monitoring system and the monitoring method, the users can comprehensively know the available state of the cloud host according to monitoring items and alarm strategies, thereby preventing the cloud host Agent from excessively occupying virtual resources of the cloud host when the monitoring projects are excessive.

Description

technical field

[0001] The invention relates to the technical field of cloud computing, in particular to a system and a monitoring method for monitoring the performance of a cloud host in the virtualization technology of cloud computing. Background technique

[0002] In the prior art, monitoring the virtual resource utilization state of an open cloud host mostly adopts the mode of setting an intermediary desktop computer (Agent) in the cloud host, and the intermediary desktop computer executes the corresponding shell script program or analyzes the Linux system / proc to obtain the resource utilization status information of the cloud host, so as to accurately obtain the virtual resource usage, so as to monitor the virtual storage resources, virtual computing resources, virtual bandwidth, data traffic and other items of the open cloud host. . However, when too many monitoring items are required for the performance of the cloud host, the agent module of the cloud host that perf...
