Fig. 2 is a system block diagram of the present invention.
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1, a method for collecting a serial log in a server management system includes the following steps:
s1: and acquiring the information of the system serial port and the network card serial port through the BMC of the server.
Collecting system Serial logs is mainly through the Serial Over LAN function, SOL Serial Over LAN refers to a mechanism to redirect Serial I/O in the system through IP-based IPMI session. Therefore, firstly, the Serial overlalan function is used for redirecting the system Serial port UART1 to the BMC Serial port UART4, and the printing information of the system Serial port UART1 is acquired through the BMC Serial port UART 4; meanwhile, the printing information of the network card serial port UART2 is directly acquired through the BMC.
S2: and monitoring the writing state of the serial port information recording file in the BMC file path, if data are written, accessing the corresponding serial port information recording file, and recording the serial port information in a preset serial port log file.
And monitoring the writing state of the/dev/ttyS 3 file corresponding to the file path of the BMC serial port UART4 aiming at the system serial port, accessing the file if data are written, and writing the information of the system serial port into a system log file. And monitoring the writing state of the/dev/ttyS 2 file under the BMC file path corresponding to the network card serial port UART2 aiming at the network card serial port, accessing the file if data are written in, and writing the information of the network card serial port into a network card log file.
Because the collected serial port information comprises system serial port information and network card serial port information, the preset serial port log file comprises a system log file and a network card log file; the system log file and the network card log file both comprise two sub-log files with the same size, and the capacity of each sub-log file is one half of the maximum capacity of the corresponding serial port log file. In this embodiment, the maximum number of the adopted system log files is 2M, and correspondingly, the capacity of each sub-log file of the system log file is 1M; the maximum network card log file is 1M, and the capacity of each sub-log file of the corresponding network card log file is 512K.
Therefore, based on the above configuration of the log file, in this step, recording the serial port information in the preset serial port log file specifically includes:
the method comprises the steps of firstly recording serial port information into one sub-log file, recording the subsequent serial port information into another sub-log file after the capacity of the sub-log file is reached, and emptying the previous full sub-log file. This is repeated. Therefore, the situation that the storage space inside the BMC is insufficient due to the fact that the file becomes infinitely large can be prevented.
S3: after the recording is finished, the serial port log file is stored in the/extlog/sollog/directory of the server and is exported and viewed through the BMC.
In addition, on the basis of the above embodiment, there is another situation that if a user uses the Serial overlay function and redirects the network card Serial port to the Serial overlay LAN Serial port UART4, the UART4 outputs the network card Serial port information, so that when recording the network card information, if the Serial overlay LAN function is turned on, it is necessary to determine the current Serial overlay LAN redirection state, and if the Serial overlay LAN function is the network card Serial port, the information acquisition from the UART2 is suspended, and the information acquisition from the UART4 is changed.
Correspondingly, as shown in fig. 2, the present invention also discloses a serial log collection system under the server management system, which includes:
the information acquisition unit is used for acquiring information of a system serial port and a network card serial port through a BMC (baseboard management controller) of the server;
the information recording unit is used for monitoring the writing state of the serial port information recording file in the BMC file path, accessing the corresponding serial port information recording file if data are written, and recording the serial port information in a preset serial port log file;
and the storage unit is used for storing the serial port log file in a preset folder of the server after the recording is finished and exporting and checking the serial port log file through the BMC.
Correspondingly, the invention also discloses a serial port log collecting device under the server management system, which comprises:
a memory for storing a computer program;
a processor for implementing the steps of the method for collecting the serial port log under the server management system as described in any one of the above when the computer program is executed.
The invention provides a method, a system and equipment for collecting serial logs under a server management system, wherein because one end of a serial port of the system is often connected with a PCH, the logs can be collected only in an SOL (System on demand) mode; however, for a device such as a network card serial port directly connected to the BMC, we do not need to rely on the SOL function, and only need to note that the current redirection state is checked when the SOL function is turned on, and a collection scheme is determined according to the state. The invention prevents the storage space deficiency caused by the infinite enlargement of the file by limiting the size of the log file, and can more timely and effectively process the fault in the server management process by collecting the serial port log in real time, thereby meeting the requirements of the new generation of platform.
The log collection of the serial port of the invention is different according to the size limit of the log file required by different platforms, and can be adjusted correspondingly on other platforms, thus having universal application value.
