Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In a server, a plurality of system firmware modules need to be debugged during development or abnormal positioning, one debugging mode is that corresponding printing information is output to a mainboard through an external debugging line and an RS232 serial port, and abnormal positioning and debugging are carried out according to the output printing information, namely corresponding abnormal firmware can be positioned manually; in another mode, when a hardware circuit is designed, serial port information of System Firmware is redirected to a network port through a BMC serial port in parallel for output, and taking a BMC AST2500 chip as an example, RX and TX signals of serial ports such as MCP (Management Control Processor), SCP (System Control Processor), ATF (arm-managed-Firmware), UEFI (Extensible Firmware Interface) and the like can be respectively communicated with TX and RX of UART1-UART4 (serial port 1 to serial port 4) of the BMC, where RX represents a signal receiving end, such as an input pin; TX denotes a signal transmitting end, e.g., an output pin. Because the serial port redirection output can only be unique, the output of the corresponding redirection serial port information needs to be controlled by manually inputting an SOL command. The server may be an arm server, an x86 server, or the like.
In order to solve the above problems, the present application provides a log output method. The log output method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. The baseboard management controller BMC is connected to the server processor cpu (central processing unit), the BIOS, and the MCP, and includes a first serial port and a second serial port, where the first serial port may be multiple. The first serial port is respectively connected with the server processor CPU, the basic input and output system BIOS and the management control processor MCP, and correspondingly outputs the log of the corresponding system. The baseboard management controller BMC obtains first log information corresponding to the first serial port, detects output conditions of the first serial port according to the first log information, and outputs the first log information corresponding to the first serial port by adopting the second serial port when detecting that the output of the first serial port is abnormal. It should be noted here that the server processor CPU, the BIOS, and the management control processor MCP are not limited to being connected to the BMC, and other controllers or systems may be connected to the BMC, and further connected to the first serial port of the BMC.
In an exemplary embodiment, as shown in fig. 2, a log output method is provided, which is exemplified by applying the method to the BMC in fig. 1, where the BMC includes a first serial port and a second serial port, and includes the following steps 202 to 206.
Wherein, the first serial port can be a plurality of. The first serial port is connected with other components to achieve communication, but the other components and the BMC run independently and do not affect each other, and the other components can output correspondingly generated logs through the first serial port to record or analyze. Among other components may be a server processor CPU, a basic input output system BIOS, a management control processor MCP, a system control processor SCP, an ATF, etc. Correspondingly, the first log information refers to log information generated by other components corresponding to the first port during operation. A first string corresponds to a first log information.
And step 204, detecting the output condition of the first serial port according to the first log information.
The first log information includes operating parameters, sensor data and other performance data involved in the operation of the corresponding component. The first log information is detected and analyzed, so that the output condition of the corresponding first serial port can be detected, for example, whether the first serial port normally operates can be judged by analyzing the sensor data recorded in the first log information corresponding to the first serial port, and the output condition of the first serial port can be detected.
And step 206, outputting the first log information corresponding to the first serial port by using the second serial port when the first serial port output is detected to be abnormal.
And when the BMC detects that the output of the first serial port is abnormal, outputting first log information corresponding to the first serial port by adopting the second serial port. Optionally, when the BMC detects that the output of the first serial port is abnormal, the BMC may send a connection switching command to the corresponding logic control component, so that the other components connected to the first serial port are switched to be connected to the second serial port, and output the first log information output by the first serial port by using the second serial port. Under a normal condition, one second serial port is adopted, so that when the output of the plurality of first serial ports is detected to be abnormal simultaneously, a first target serial port can be determined from the plurality of first serial ports according to preset conditions, and first target log information corresponding to the first target serial port is output by adopting the second serial port.
In the log collection method, first log information corresponding to a first serial port is obtained; detecting the output condition of the first serial port according to the first log information; and when the first serial port output is detected to be abnormal, outputting first log information corresponding to the first serial port by adopting the second serial port. According to the embodiment of the application, the first serial port and the second serial port are arranged in the BMC, the output condition of the first serial port is detected according to the first log information corresponding to the first serial port, when the first serial port is abnormal in output, the second serial port is adopted to output the first log information corresponding to the first serial port, abnormal conditions of the first serial port can be used for positioning abnormal firmware of the server, meanwhile, normal output of logs corresponding to corresponding abnormal firmware can be guaranteed, and therefore log collection efficiency is improved.
In one embodiment, as shown in fig. 3, when it is detected that the first serial port output is abnormal, the step 206 of outputting the first log information corresponding to the first serial port by using the second serial port includes the following steps 302 to 304.
When the BMC detects that a plurality of first serial ports output at the same time are abnormal, a first target serial port with the highest priority in the abnormal first serial ports can be determined according to the priority of the first serial ports. The priority of the first serial port can be set according to the importance degree or the emergency degree of the first log information corresponding to the first serial port, and the corresponding relation between the priority of the first serial port and the first serial port is stored in advance, so that the priority can be obtained in time when the BMC processes the first serial port conveniently.
And step 304, outputting the first target log information corresponding to the first target serial port by using the second serial port.
And after the abnormal first target serial port is determined, outputting first target log information corresponding to the first target serial port by adopting the second serial port. Optionally, the BMC may send a connection switching command to a corresponding Logic control component, for example, a PLC (Programmable Logic Controller) or a CPLD (Complex Programmable Logic device) component, so that the Logic control component automatically switches an object connected to the first target serial port to be connected to the second serial port, so that the second serial port may output first target log information corresponding to the first target serial port.
In this embodiment, when it is detected that a plurality of first serial ports output at the same time are abnormal, according to the priority of the first serial ports, the first target serial port with the highest priority in the abnormal first serial ports is determined, and the first target log information corresponding to the first target serial port is output by the second serial port, so that when the first serial ports are abnormal, the first target log information of the first target serial port with the highest priority can be output by the second serial port in time, and the first target log information is collected so as to analyze the corresponding abnormal problem in time, thereby improving the log collection quality. In some embodiments, as shown in fig. 4, the log collection method further includes the following steps 402 to 406.
And step 404, outputting first target log information corresponding to the first target serial port by using the second serial port.
And 406, redirecting the serial port to the socket SOL by using the serial port to output second target log information corresponding to a second target serial port, wherein the second target serial port is the serial port with the highest priority level in the abnormal first serial ports.
In this embodiment, the descriptions of step 302 to step 304 may be referred to in step 402 to step 404, which are not repeated herein. The serial port is redirected to a network port SOL (Serial Over lan), and the SOL provides a mechanism to enable a serial port controller of a remote management system to be redirected to the local through an IPMI session based on an IP network. In general, serial ports are an indispensable tool for repairing system failures and BIOS anomalies. When the machine has a fault, system management personnel can carry out the related configuration of the BIOS, the operating system and the network through the serial port to repair the system. In the past situation, a manager has to return to a noisy machine room, re-access the serial port and then perform repair work. The SOL provides the administrator with the access to the serial port of the remote system based on the IP, and the administrator can access the serial port of the failed machine through any host supporting the SOL as long as the network in the machine room does not fail. That is, the redirection of the serial port to the socket SOL is through the network
In an alternative embodiment, the communication link between the BMC and a remote PC (Personal Computer) is established by the SOL protocol of the IPMI standard. An SOL service is established inside the BMC, and the SOL service can realize data stream transmission in two directions, namely, the SOL service can transmit first serial port data to the remote PC, and the remote PC transmits the data to the first serial port through the SOL service. The SOL service reads data of the first serial port, the remote PC opens the SOL client, the SOL client initiates a data request to the SOL service, the SOL receives the data request and transmits the data to the SOL client of the remote PC, and the SOL client can display the received data. A user writes data in an SOL client of a remote PC, the SOL client transmits the data to SOL service through a network, the SOL service transmits the data to a first serial port after receiving the data, and the first serial port can receive the data input by the remote PC.
In this embodiment, when it is detected that a plurality of first serial ports output at the same time are abnormal, according to the priority of the first serial ports, a first target serial port with the highest priority in the abnormal first serial ports is determined, and a second serial port is used to output first target log information corresponding to the first target serial port; and meanwhile, the serial port is used for redirecting to the network port SOL to output second target log information corresponding to a second target serial port, wherein the second target serial port is the serial port with the highest priority level in the abnormal first serial ports, so that the log information of the two first serial ports can be printed simultaneously, the first log information corresponding to the abnormal first serial ports can be fully collected, and more log information can be obtained for analyzing the abnormality.
In some possible embodiments, the log collection method further comprises:
acquiring a start flag bit of SOL;
and determining a serial port switching mode of the SOL according to the starting flag bit, wherein the serial port switching mode comprises a manual mode and an automatic mode.
In this embodiment, the start flag of the SOL is used to determine the start mode of the SOL. The start flag bit of SOL may be presented in the form of hardware or a function. The BMC may be available from SOL services, or from a remote PC via a network. And determining a serial port switching mode of the SOL according to the start flag bit of the SOL, wherein the serial port switching mode comprises a manual mode and an automatic mode. In the manual mode, when the redirection to the internet port by using the serial port is triggered, an SOL command is manually input to control the output of serial port information. The automatic mode is automatically switched when the redirection to the internet port by using the serial port is triggered.
In an alternative embodiment, the serial port switching mode of the SOL may be determined by determining a flag bit of a GPIO (General Purpose Input Output) connected to the BMC. When the flag bit of the GPIO is 1, the mode of serial port switching of the SOL is an automatic mode; and when the flag bit of the GPIO is 0, the serial port switching mode representing the SOL is a manual mode.
In an alternative embodiment, the serial port switching pattern of SOL may be determined by the value of the flag function. When the value of the mark function is 1, representing that the serial port switching mode representing the SOL is an automatic mode; when the value of the flag function is 0, the serial port switching mode representing the SOL is the manual mode.
In one embodiment, the log collection method further comprises:
and storing the first target log information output by the second serial port in a log storage space of the BMC according to the priority of the first serial port.
In this embodiment, according to the priority of the first serial port, the first target log information output by the second serial port is stored in the log storage space of the BMC, so that the log information stored in the log storage space is analyzed to find abnormality and debug, wherein the log data stored in the log storage space does not disappear even when the power is off, and subsequent analysis is facilitated. It should be noted that the log storage space is not limited to the storage space configured by the BMC itself, and may also be a storage space that needs to be increased according to an actual application scenario, for example, an extrapolated SD card. The second serial port outputs the same first log information at the same time, when the output of the first serial port corresponding to the first log information is recovered to be normal, the first log information corresponding to the output of the first serial port is recovered, therefore, a plurality of first log information corresponding to the first serial port output by the second serial port may exist in the storage space, when the storage space reaches the storage space threshold value of the storage space, the first target log information output by the second serial port is stored in the log storage space of the BMC according to the priority of the first serial port, namely, the first target log information corresponding to the first serial port with the highest priority is preferentially stored.
In one embodiment, as shown in fig. 5, the log collection method further includes the following steps 502 to 506.
In the log storage space of the BMC, the log storage space is divided into different log storage subspaces according to the degree of the abnormal severity, for example, if the abnormal severity is 3 degrees, the log storage space is divided into three log storage subspaces on average or in proportion, that is, the three log storage subspaces may be the same or different in size. And acquiring the abnormal severity of the first serial port output, and acquiring a corresponding storage space threshold according to the abnormal severity, wherein the storage space threshold is not larger than the size of the log storage subspace corresponding to the abnormal severity.
And detecting whether the size of the log storage subspace corresponding to the abnormal severity reaches the storage space threshold value or not by judging the relationship between the size of the log storage subspace corresponding to the abnormal severity and the corresponding storage space threshold value.
In step 506, when the storage space threshold is reached, the first log information which is currently output is overwritten on the log information which is stored first in the storage space corresponding to the abnormal severity.
And when the size of the log storage subspace corresponding to the abnormal severity reaches the storage space threshold, covering the first log information which is output currently to the log storage subspace and is stored firstly.
In this embodiment, by obtaining the abnormal severity of the first serial port output, obtaining the corresponding storage space threshold according to the abnormal severity, detecting whether the actual storage condition of the corresponding storage space reaches the storage space threshold, and when the actual storage condition of the corresponding storage space reaches the storage space threshold, covering the first log information output currently with the log information stored first in the corresponding storage space, the maximum utilization of the log storage space can be achieved, and meanwhile, the collected logs are stored for as long as possible.
In one embodiment, as shown in FIG. 6, the log collection method includes the following steps 602 to 612.
And 608, outputting the first target log information corresponding to the first target serial port by using the second serial port.
And step 610, redirecting the serial port to the network port SOL by using the serial port to output second target log information corresponding to a second target serial port, wherein the second target serial port is the serial port with the highest priority level in the abnormal first serial ports.
And step 612, storing the first target log information output by the second serial port in a log storage space of the BMC according to the priority of the first serial port.
In an embodiment, taking AST2500 as an example, the BMC is provided with 5 physical serial ports, which are UART1, UART2, UART3, UART4 and UART5 in sequence, where UART1 is externally connected to the BIOS/OS, UART2 is externally connected to the MCP, UART3 is externally connected to the SCP, UART4 is externally connected to the ATF, UART5 is a BMC serial port, that is, UART1 to UART4 are first serial ports, and UART5 is a second serial port. It should be noted that, except for the second serial port, the connection correspondence between the first serial port and other components is not specifically limited herein. When the BMC detects that the system is in a standby state and a normal operation state, the UART5 is maintained to be output by a BMC serial port; when the system normally operates, starting SOL to output according to the default UART1 under the condition that the network is normally connected; when the system is not powered on, the UARTs 1-4 have no output.
When the BMC detects that the output of the first serial port is abnormal according to the first log information corresponding to the first serial port, the BMC outputs the first log information corresponding to the first serial port by adopting the second serial port. For example, if the BIOS starts up and fails, which indicates that the UART1 output is abnormal, the BMC automatically outputs the print information corresponding to the UART1 using the UART 5. For another example, if the MCP cannot acquire the CPU temperature, voltage, or the like, which indicates that the output of the UART2 is abnormal, the BMC automatically outputs the print information corresponding to the UART2 using the UART 5. When the condition that the BIOS start fails and the MCP cannot acquire the temperature or the voltage of the CPU at the same time occurs, it is indicated that both the outputs of the UART1 and the UART2 fail, according to the priority conditions of the UART1 and the UART2, the serial port printing information with the highest priority is output by adopting the UART5, if the priority of the UART1 is the highest, the printing information corresponding to the UART1 is output by adopting the UART5, and because the priority of the UART2 is the highest, the serial port is used for redirecting to the network port to output the printing information corresponding to the UART 2. The log information output by the UART5 is saved in the log storage space of the BMC.
In an embodiment, a flow diagram of the log collection method is shown in fig. 7, and when there are multiple abnormal serial ports of the system firmware, the BMC serial port is used to output the serial port with the highest priority of the abnormal serial port of the system firmware according to the priority of the abnormal serial port of the system firmware; redirecting to a serial port with the highest priority of a system firmware serial port with abnormal network port SOL output by using the serial port; for other abnormal system firmware Serial ports, for example, Serial ports with the priority level of the system firmware Serial port arranged at the third position, a local debugging line, for example, an RS232 Bus, may be manually accessed at an abnormal position for debugging, and corresponding log information may be acquired and output through a USB (Universal Serial Bus). The BMC serial port output is adopted to obtain and output corresponding log information through a local debugging line, such as an RS232 bus, and a USB; the redirection from the serial port to the network port SOL output is realized by outputting from the network port through a network, and finally, the log information corresponding to the serial port is sent to a remote PC.

The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
