Detailed Description
The terminology used in the embodiments of the disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to any or all possible combinations including one or more of the associated listed items.

In one technical scheme, when a server device fails on a deployment site, such as a downtime, a restarting or an error reporting problem, an SDS log of the BMC is collected, but the log of an operating system which can be checked by the method is very small, particularly after the system is restarted, some system logs are not necessarily recorded, in order to locate the problem, a plurality of times of reproduction are sometimes required to be carried out, a key log is possibly obtained, and if a plurality of machines with different problems appear, the problem reproduction, collection and location of each server are also carried out.
In another technical scheme, after a problem occurs, a diagnosis log collection command of the system is directly input under an operating system, for example, a red cap can collect current system diagnosis log information through a sosreport command, and the current system diagnosis log information is stored under a/var/tmp directory by default. However, after each time the system is down, the log is not necessarily detailed, even the log is lost after the system is restarted, most of the problems need to be repeated by engineers for a plurality of times, and key information can be captured only by starting the debug, so that the mode wastes manpower and time.

step S13, storing the redirected serial port into a storage space of the management device, so that the management device obtains the system log file and diagnoses the system log file in response to the diagnosis command.
And a third party device management device is arranged outside the server needing operation and maintenance, and the system log file before downtime of the server is saved through a redirected interface, so that the checked log is complete and large in information quantity, the log file is not recorded completely or lost because of restarting the server, the problem and fault reproduction of the operation and maintenance positioning server are facilitated, and the operation and maintenance efficiency is improved.
The management device can diagnose the system log file only after the user issues a diagnosis command, wherein the diagnosis command can be issued automatically according to the configuration of the user or manually selected by the user according to the field requirement.
In one embodiment, the fault event triggered on the server scans and collects the system log file through vmcore of kdump function, including: and starting watchdog early warning and memory overflow early warning.
In one embodiment, the management device is a mobile computing device that establishes a network connection with the server, or a server that establishes a network connection with the server, or a USB disk system that establishes a communication connection with the server through a USB port.

step S22, receiving and storing a system log file transmitted by a server through a redirected serial port;
step S23, fault diagnosis is conducted on the system log file in response to the diagnosis command.
And a third party device management device is arranged outside the server needing operation and maintenance, and the system log file before downtime of the server is saved through a redirected interface, so that the checked log is complete and large in information quantity, the log file is not recorded completely or lost because of restarting the server, the problem and fault reproduction of the operation and maintenance positioning server are facilitated, and the operation and maintenance efficiency is improved.
The management device can diagnose the system log file only after the user issues a diagnosis command, wherein the diagnosis command can be issued automatically according to the configuration of the user or manually selected by the user according to the field requirement.
In one embodiment, the issuing a configuration command to the managed server, where the configuration command is used to enable the kdump function by the server and redirect the serial port to the storage space of the management device includes: the configuration command is also used for enabling the server to start watchdog early warning and memory overflow early warning.

In one embodiment, before the system of the server is restarted or down, the management device serves as an external diagnostic device for a third party, and collects fault logs of the server in real time in batches, wherein the management device needs to ensure that a network of the server is reachable. When the method is implemented, a user can selectively add the server equipment which is expected to be managed into management through IP scanning, the command terminal which logs in the server is accessed by utilizing the built-in ssh function, and a configuration command is issued to the managed server in batches, so that the following operations are realized: enabling kdump function, starting early warning when watchdog and memory overflow under the system, starting serial port redirection, collecting serial port printing information, and scanning files under/var/log in real time.
Because the watchdog and memory overflow early warning and kdump functions are set in the configuration, if the system is down, before the system is down, the system triggers the self-collection of vmcore files, and the log storage module plays a role that the self-collected logs are directly redirected into an external storage space through the original serial port redirection setting function before the system is restarted. If the system is not down, the user can selectively collect the system logs which the user wants to collect. Because the storage module can customize storage positions and storage spaces, a client can flexibly adjust the storage spaces in use, and in addition, the log does not run on an actual server and does not influence server business.
The fault diagnosis can be realized in the form of a diagnosis package, the diagnosis package comprises common fault definitions, and when the fault is analyzed and loaded in response to a diagnosis command of a user, the fault condition can be displayed in a matching way through matching key fault fields, and a preliminary fault analysis conclusion is given. When the user selects to analyze the log, automatic analysis can be started according to the configuration, key fault fields are analyzed, then the system is matched with fault analysis conclusions recorded by the system according to the key fault fields, and finally preliminary fault conclusions are displayed back to the user according to the matching results. The user of the present disclosure may operate and maintain personnel.
