Abstract

The invention relates to the technical field of servers, and provides a method and system for remotely collecting downtime information of a Linux system, and the method comprises the steps: controlling to activate a serial communication sol mechanism on a local area network; when a serial communication sol mechanism on the local area network is activated, obtaining and analyzing state informationof the Linux system; acquiring the level of the operating system responding to the interrupt signal; when it is judged that the operating system influences a part of interrupt signals, locating and analyzing a fault that the operating system does not respond according to the obtained vmcore file and the file collected by the sosreport; when it is judged that the operating system cannot respond toany interrupt signal, waiting for a trigger condition set by the kdump to generate a vmcore file, and positioning and analyzing a non-response fault of the operating system according to the vmcore file, thereby accurately positioning the non-response problem of the operating system by using the function of a magic key in the session establishment period between the remote console and the server.

Description

technical field

[0001] The invention belongs to the technical field of servers, and in particular relates to a remote collection method and system for Linux system downtime information. Background technique

[0002] When performing performance tests on servers, system unresponsiveness is a common and serious problem in server testing and production environments, especially for production environments. If you cannot quickly respond to user needs, quickly locate and solve customer problems, you will often fail cause heavy losses to customers. When the system does not respond, how to quickly and accurately locate the root cause of the problem, so as to solve and completely avoid such problems, is the most concerned issue for customers, software and hardware providers, and integrators.

[0003] At present, when the Linux system goes down, technicians need to arrive at the scene to collect information, and remote operations cannot be performed. Contents of the invention [00...
