In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather construed as limited to the embodiments set forth herein.

The switch: a network device for electrical (optical) signal forwarding.
Bmc (baseboard Management controller): a management processor, a processor in the switch for managing power, temperature sensing and anomaly monitoring.

In order to show the present application more clearly, the application scenarios provided by the embodiments of the present application are introduced first. Fig. 1 is a schematic diagram of an embodiment of an application scenario provided in the present application. The method comprises the following steps that a client 1-1 is connected with a switch 1-2 firstly, the client configures and controls the switch, the switch returns data to the client, and a main processor in the switch sends serial port data of the main processor to a programmable logic device; the programmable logic device acquires serial port data of a main processor, mirrors the serial port data of the main processor to acquire serial port mirror image information, and transmits the serial port mirror image information to the management processor; the management processor stores the serial port mirror image information into a log file and sends the log file to the log server 1-3.
A first embodiment of the present application provides a log information processing system, which is described below with reference to fig. 2.
As shown in fig. 1, the log information processing system includes: programmable logic device 2-1, main processor 2-2, management processor 2-3.
The programmable logic device 2-1 is configured to mirror the serial port data of the main processor to obtain serial port mirror image information, and transmit the serial port mirror image information to the management processor.
The programmable logic device is further configured to: and acquiring serial port data of the main processor.
The programmable logic device may include: a CPLD (Complex Programmable Logic Device), an FPGA (Field-Programmable Gate Array), etc., as shown in fig. 2, where the Programmable Logic Device is a CPLD.
The programmable logic device obtains serial data output by a serial port (for example, a universal asynchronous receiver and transmitter UART0 serial port in FIG. 2) of a main processor (Host CPU in FIG. 2); then, carrying out mirror image processing on the serial port data to obtain serial port mirror image information; and then the serial port mirror image information is transmitted to a management processor of the switch. The programmable logic device is specifically configured to: and transmitting the serial port mirror image information to a log record serial port of a management processor of the switch.
The programmable logic device is further configured to: and transmitting the serial port mirror image information to a panel serial port of the switch.
In specific implementation, because the serial port data of the main processor needs to be output to both the panel serial port and the log record serial port of the management processor of the switch (for example, UART1 in fig. 2 is a log record serial port), the CPLD first performs mirror image processing on the serial port data after obtaining the serial port data output by the serial port of the main processor to obtain serial port mirror image information; and then the serial port mirror image information is transmitted to the management processor through one path, and simultaneously the serial port mirror image information is transmitted to the panel serial port of the switch through the other path.
Because the serial port mirror image information is obtained by adopting the programmable logic device to carry out mirror image processing on the serial port data, the serial port data of the main processor is simultaneously output to the panel serial port and the log record serial port of the management processor, and a precondition is provided for the management processor to store the serial port log.
And the main processor 2-2 is used for sending the serial port data of the main processor to the programmable logic device.
And the management processor (for example, BMC in fig. 1) 2-3 is configured to receive serial port image information of the main processor output by the programmable logic device, and record the serial port image information in the log file.
The management processor is specifically configured to:
starting a log process;
and saving the serial port mirror image information to the log file by using the log process.
The management processor is specifically configured to:
and saving the log file to a nonvolatile storage medium.
The non-volatile storage medium includes at least one of the following media:
a non-volatile memory;
and (5) a Flash chip.
In specific implementation, a Log process (e.g., a Log saving process in fig. 2) may be run in the management processor, serial port image information is obtained through the Log process, a write interface of Flash is called, and the serial port image information is written into a Log file.
If all serial port mirror image information is written into a log file, the limitation of available storage equipment space may be caused after a period of time, so that some historical information is covered; in addition, if a single log file is too large, the speed of searching for specific information is affected, and the operation and maintenance personnel cannot quickly troubleshoot the problems. Therefore, the local log file can be timely transmitted to the weblog server according to the capacity of the nonvolatile storage medium and the size of the log file, and particularly, the log file can be transmitted to the log server through the out-of-band management network.
As an embodiment, two log files may be set in the non-volatile storage medium, and when the size of the log file being written is greater than or equal to a preset file size threshold, the log file is transmitted to the log server, and the serial port image information is saved in the other log file.
As an example, in order to improve the search speed of the log information in a specific time, a manner of reducing the capacity of each log file may be adopted. Specifically, more log files can be set according to the capacity of the nonvolatile storage medium, when the size of one log file is larger than or equal to a preset file size threshold, the serial port mirror image information log file is stored in another log file until the serial port mirror image information is stored in the last log file, and all the log files in which the serial port mirror image information is stored in the front are transmitted to the log server together. For example, 5 log files with the same size are set according to the capacity of the nonvolatile storage medium, and when serial port image information is saved to the 5 th log file, the remaining 4 log files can be transmitted to the log server together.
As an embodiment, before the step of recording the serial port image information to the log file, the method may further include the following steps: and processing the serial port mirror image information to obtain the log information conforming to the log file format. The recording the serial port mirror image information into the log file comprises: and saving the log information conforming to the log file format into the log file. Because the serial port mirror image information is a binary data stream, the serial port mirror image information can be processed firstly, converted into log information conforming to the format of a log file, and then the log information conforming to the format of the log file is stored in the log file.
In order to realize the diagnosis of the switch and the main processor by the operation and maintenance personnel, only the log records with the log record level greater than or equal to the preset log record level threshold value can be saved.
The saving the log information conforming to the log file format to the log file comprises:
judging whether the log record grade of the log record in the log information conforming to the log file format is greater than or equal to a preset log record grade threshold value or not;
and if so, saving the log information conforming to the log file format into the log file.
The logging level includes a severity level, an error level, a warning level, an information level, and a debugging level.
For example, if the preset logging level threshold is an alarm level, log records greater than or equal to the alarm level (including severity level, error level, alarm level) are saved to a log file.
Thus, the description of the first embodiment of the present application is completed. According to the first embodiment of the application, the mirror image output to the serial port of the main processor of the switch is realized through the programmable logic device, the mirror image is routed to the log recording serial port of the management processor, the log running process of the management processor continuously stores the serial port mirror image information to an external nonvolatile storage medium in a file mode, the complete storage of the serial port log of the main processor can be realized, and the diagnosis of the switch and the main processor by data center network operation and maintenance personnel is facilitated. In particular, these log files can restore details prior to the failure when a hang up of the host processor occurs or the system is restarted.
Compared with the scheme of saving the serial log which is realized by completely depending on the programmable logic, the first embodiment of the application has higher flexibility by using the management processor to save the serial log: (1) the log file can be checked at any time, and the log storage is not interrupted; (2) the management processor can upload the locally stored files to a log server on the network using an out-of-band management network without the limitation of local storage. In the scheme of using programmable logic to realize serial port log storage, when log content needs to be checked or historical logs need to be backed up, a log storage task needs to be suspended, and the integrity of the logs cannot be ensured.
A second embodiment of the present application provides a log information processing method, and an execution main body of the second embodiment of the present application is a programmable logic device of a switch. This is explained below with reference to fig. 3.
As shown in fig. 3, in step S301, serial port data of the main processor is acquired.
The step of acquiring the serial port data of the main processor refers to the step of acquiring the serial port data of the main processor of the switch by the programmable logic device of the switch.
As shown in fig. 2, the programmable logic device obtains serial data output by the serial port (universal asynchronous receiver and transmitter UART0 serial port) of the main processor (Host CPU of fig. 1).
As shown in fig. 3, in step S302, serial port data of the main processor is mirrored to obtain serial port mirror information.
As shown in fig. 3, in step S303, the serial port image information is transmitted to the management processor.
The management processor is used for managing power supply, temperature and abnormality monitoring in the switch
When the programmable logic device of the switch transmits the serial port mirror image information to the management processor of the switch, the programmable logic device of the switch can also transmit the serial port mirror image information to the panel serial port of the switch.
The step of transmitting the serial port mirror image information to a management processor comprises the following steps:
and transmitting the serial port mirror image information to a log record serial port of a management processor of the switch.
In specific implementation, because the serial port data of the main processor needs to be output to both the panel serial port and the log record serial port of the management processor of the switch (for example, UART1 in fig. 2 is a log record serial port), after the CPLD obtains the serial port data output by the serial port of the main processor, the CPLD first performs mirror image processing on the serial port data to obtain serial port mirror image information, and then transmits the serial port mirror image information to the management processor of the switch through one path, and simultaneously transmits the serial port mirror image information to the panel serial port of the switch through the other path.
Because the serial port mirror image information is obtained by adopting the programmable logic device to carry out mirror image processing on the serial port data, the serial port data of the main processor is simultaneously output to the panel serial port and the log recording serial port of the management processor of the switch, and the complete storage of the serial port data of the main processor is realized by combining with the log process built in the management processor.
A third embodiment of the present application provides a log information processing method, and an execution main body of the third embodiment of the present application is a management processor of a switch. This is explained below with reference to fig. 4.
As shown in fig. 4, in step S401, serial port mirror information of the main processor output by the programmable logic device is obtained.
The programmable logic device may include: a CPLD (Complex Programmable Logic Device), an FPGA (Field-Programmable Gate Array), etc., as shown in fig. 2, where the Programmable Logic Device is a CPLD.
In the second embodiment of the present application, the programmable logic device obtains serial data output by a serial port (for example, a universal asynchronous receiver and transmitter UART0 serial port in fig. 2) of a main processor (Host CPU in fig. 2); then, carrying out mirror image processing on the serial port data to obtain serial port mirror image information; and then the serial port mirror image information is transmitted to a management processor of the switch, and the management processor obtains the serial port mirror image information of a main processor output by a programmable logic device in the switch. As shown in fig. 2, the log process executed by the management processor may intercept serial mirror information of the main processor, which is input to the log recording serial port of the management processor by the programmable logic device in the switch.
As shown in fig. 4, in step S402, the serial port image information is recorded in the log file.
The recording the serial port mirror image information into the log file comprises:
starting a log process;
and recording the serial port mirror image information into the log file by utilizing the log process.
As an embodiment, the following steps may be further included:
and saving the log file to a nonvolatile storage medium.
The non-volatile storage medium includes at least one of the following media:
a non-volatile memory;
and (5) a Flash chip.
In specific implementation, a Log process (e.g., a Log saving process in fig. 2) may be run in the management processor, serial port image information is obtained through the Log process, a write interface of Flash is called, and the serial port image information is written into a Log file. As shown in fig. 2, the Log process (Log saving process) completely saves the serial port mirror image information to the external Flash.
If all serial port mirror image information is written into a log file, the limitation of available storage equipment space may be caused after a period of time, so that some historical information is covered; in addition, if a single log file is too large, the speed of searching for specific information is affected, and the operation and maintenance personnel cannot quickly troubleshoot the problems. Therefore, the local log file can be timely transmitted to the weblog server according to the capacity of the nonvolatile storage medium and the size of the log file, and particularly, the log file can be transmitted to the log server through the out-of-band management network.
As an embodiment, two log files may be set in the non-volatile storage medium, and when the size of the log file being written is greater than or equal to a preset file size threshold, the log file is transmitted to the log server, and at the same time, the serial port image information is saved in another log file.
As an example, in order to improve the search speed of the log information in a specific time, a manner of reducing the capacity of each log file may be adopted. Specifically, more log files can be set according to the capacity of the nonvolatile storage medium, when the size of one log file is larger than or equal to a preset file size threshold, the serial port mirror image information log file is stored in another log file until the serial port mirror image information is stored in the last log file, and all the log files in which the serial port mirror image information is stored in the front are transmitted to the log server together. For example, 5 log files with the same size are set according to the capacity of the nonvolatile storage medium, and when serial port image information is saved to the 5 th log file, the remaining 4 log files can be transmitted to the log server together.
As an embodiment, before the step of saving the serial port image information to the log file, the method may further include the following steps: and processing the serial port mirror image information to obtain the log information conforming to the log file format. The recording the serial port mirror image information into the log file comprises: and saving the log information conforming to the log file format into the log file. Because the serial port mirror image information is a binary data stream, the serial port mirror image information can be processed firstly, converted into log information conforming to the format of a log file, and then the log information conforming to the format of the log file is stored in the log file.
In order to realize the diagnosis of the switch and the main processor by the operation and maintenance personnel, only the log records with the log record level greater than or equal to the preset log record level threshold value can be saved.
The storing the log information conforming to the log file format into the log file includes:
judging whether the log record grade of the log record in the log information conforming to the log file format is greater than or equal to a preset log record grade threshold value or not;
and if so, saving the log information conforming to the log file format to the log file.
The logging level includes a severity level, an error level, a warning level, an information level, and a debugging level.
For example, if the preset logging level threshold is an alarm level, log records greater than or equal to the alarm level (including severity level, error level, alarm level) are saved to a log file.
Thus, the description of the third embodiment of the present application is completed. The management processor receives serial port mirror image information of a main processor output by a programmable logic device in the switch, and the running log process continuously stores the serial port mirror image information to an external nonvolatile storage medium in a file form, so that complete storage of the serial port of the main processor can be realized, and diagnosis of the switch and the main processor by a data center network operation and maintenance system and operation and maintenance personnel is facilitated. In particular, these log files can restore details prior to the failure when a hang up of the host processor occurs or the system is restarted.
