Abstract: With the development of cloud computing, cloud hosting is not only facing the security problem of traditional host, but also facing problem of cloud security. For vulnerability intrusion, virtual host escapes and other issues, cloud platform absence of host monitoring methods. Because of inserting the probe point in the key positions of the function of the Linux kernel and collecting the required information of system process in the kernel layer, the implementation method and the design process and of the monitoring system information which based on kernel Kprobe mechanism has been proposed. The scheme above can not only be helpful to keep security of the system and data of the cloud virtual host, but also Improve the monitoring system of the cloud platform. Through the system performance testing before and after the installation of application in the system, that the process monitoring method which designed can be proved to Occupy lower system resource, so that the design scheme of the system is proved to have better feasibility.
