Method for operations of virtual machines in monitoring cloud activities, system, and device applying the method

A method of monitoring operations of virtual machines, applicable in a virtual machine operation monitoring system with a central monitoring system, a cloud platform, virtual exchangers, and virtual machines;

• the method comprises:
• the central monitoring system sends an obtaining instruction with a virtual network identifier and an IP address of the virtual machine to the cloud platform;
• the cloud platform transmits the obtaining instruction to the virtual exchanger;
• the virtual exchanger transmits the obtaining instruction to the virtual machine corresponding to the IP address in the obtaining instruction;
• the virtual machine searches for operation information based on the obtaining instruction and sends the searched operation information to the virtual exchanger;
• the virtual exchanger transmits the operation information to the cloud platform;
• the cloud platform transmits the operation information to the central monitoring system;
• and
• the central monitoring system monitors and manages the operation information;
• wherein the central monitoring system comprises a Zabbix server;
• the virtual machine comprises a Zabbix client;
• the method further comprises:
• the Zabbix server sends the obtaining instruction to the cloud platform;
• the cloud platform transmits the obtaining instruction to the virtual machine through the virtual exchanger;
• and
• the Zabbix client in the virtual machine searches for operation information based on the obtaining instruction;
• wherein a network node of the cloud platform sets a proxy server;
• the method further comprises:
• the proxy server receives the obtaining instruction from the Zabbix server;
• the proxy server connects with the virtual exchanger through a network namespace;
• the proxy server transmits the obtaining instruction to the virtual exchanger;
• the proxy server receives the operation information transmitted by the virtual exchanger;
• and
• the proxy server transmits the operation information to the Zabbix server.
