Description
Technical Field
The invention relates to the technical field of servers. The invention further relates to a method and a device for generating the BMC log.
Background
Logging is a very important information material in BMC systems, such as SEL logs. It records the detailed information of the system event, including the event occurrence time, the information of the related sensors and the event trigger reason. However, the "event occurrence time" may not have the correct information for logging because the BMC system time has not been initialized.
When an ipmitool is used to query the SEL log, the returned SEL records may have information such as "1 | Pre-inittime-stamp | Voltage #0x6e | Lower Critical high | Asserted", and the event occurrence Time of the SEL records may only display "Pre-inittime-stamp" because the BMC system Time is not initialized.
The problem with Pre-Init Timestamp is often discussed, for which it may even be advisable in some systems to filter out the records of Pre-Init Timestamp-stamp. Such recommendations are not of importance on behalf of these records, but rather fear that these incomplete information could cause misjudgment by system administrators or programs.
Therefore, a solution to the above problems in the prior art needs to be provided, in which complete log information is generated, so as to improve the log system of the server.

Detailed Description
While the present invention may be embodied in various forms, there is shown in the drawings and will hereinafter be described some exemplary and non-limiting embodiments, with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.
Fig. 1 shows a schematic block diagram of an embodiment of a method of generating a BMC log according to the present invention. In the embodiment shown in the figure, the method comprises at least the following steps:
s1: starting a Monotonic timer and starting BMC system time initialization;
s2: responding to the occurrence of the event to be recorded, recording the information of the event to be recorded and the occurrence timestamp of the Monotonic timer when the event to be recorded occurs;
s3: responding to the completion of the initialization of the BMC system time, and calculating the actual occurrence time of the event to be recorded based on the current system time, the current Monotonic timer time and the occurrence timestamp;
s4: and generating log information of the event to be recorded based on the actual occurrence time and the information of the event to be recorded.
In order to determine the actual occurrence time of the event, a time standard for reference needs to be provided for the BMC system, so the invention adopts a montonic timer. Therefore, step S1 starts the montonic timer before beginning BMC system time initialization, preferably before the BMC system starts logging. Thus, when the event to be recorded occurs, the step S2 records the information of the event to be recorded and the occurrence timestamp T of the montonic timer when the event to be recorded occursmono_record. Then waiting for the initialization of the BMC system time, starting a thread to check the BMC system time after the initialization of the BMC system time is completed, and step S3 is based on the current systemTime Tinited_currentCurrent Monotonic timer time Tmono_currentAnd the occurrence time stamp T recorded in step S2mono_recordCalculating the actual occurrence time T of the event to be recordedreal. The actual time of occurrence T of the event to be recorded is thus deduced back by means of a montonic timerreal. Finally, step S4 is based on the actual occurrence time T obtained in step S3realAnd generating complete log information of the event to be recorded by the information of the event to be recorded.
Further embodiments of the present invention will be described below, it being noted that the numbering of the steps mentioned therein is used only for the convenience of unambiguously indicating the step without any particular indication, and does not limit the order of the steps described.
In some embodiments of the method for generating a BMC log of the present invention, the step S2, in response to the event to be recorded occurring, the recording information of the event to be recorded and the occurrence timestamp of the montonic timer when the event to be recorded occurs further includes:
s21: in response to the occurrence of the event to be recorded, checking the state of the BMC system time initialization;
s22: responding to incomplete initialization of the BMC system time, and recording information of an event to be recorded and an occurrence timestamp of a Monotonic timer when the event to be recorded occurs;
s23: and responding to the completion of the initialization of the BMC system time, and generating log information of the event to be recorded based on the system time when the event to be recorded occurs and the information of the event to be recorded.
Since the method of the present invention is intended to improve the log before the BMC system time initialization is not completed, in the above embodiment, when the event to be recorded occurs, step S21 first checks the state of the BMC system time initialization. If the BMC system time initialization is not completed at this time, step S22 records the occurrence timestamp T of the Monotonic timer when the event to be recorded occursmono_record. If the initialization of the BMC system time is finished at the moment, only the generation process of the log needs to be normally carried out, namely, the system time T when the event to be recorded occurs is basedinited_currentAnd generating the log information of the event to be recorded by the information of the event to be recorded.
In several embodiments of the method for generating a BMC log of the present invention, the step S2, in response to the event to be recorded occurring, recording information of the event to be recorded and an occurrence timestamp of a montonic timer when the event to be recorded occurs, further includes: and in response to the occurrence of the event to be recorded, storing the recorded occurrence time stamp and the information of the event to be recorded into a storage space in a predetermined format. Regardless of whether the BMC system time is successfully set, the BMC must ensure that all log information can be read normally at any time without loss or confusion. Therefore, when an event to be recorded occurs, the occurrence time stamp T of the recording is first stampedmono_recordAnd storing the information of the events to be recorded into other storage spaces except the date-to-date database so as to ensure that the related information is not lost and can be called when needed. During storage, preferably, a field for storing the timestamp of the Monotonic timer is added in addition to the original event generation time field.
In one or more embodiments of the method for generating a BMC log of the present invention, the step S3, in response to the BMC system time initialization being completed, the calculating an actual occurrence time of the event to be recorded based on the current system time, the current montonic timer time, and the occurrence timestamp further includes:
s31: acquiring an occurrence time stamp from a storage space;
s32: the actual time of occurrence is calculated by subtracting the time difference between the current Monotonic timer time and the time stamp of occurrence from the current system time.
Due to the occurrence time stamp T of the Monotonic timer when the event to be recorded occursmono_recordHas been recorded in the storage space, so that the actual occurrence time T of the event to be recorded is estimated when step S3realFirst, step S31 acquires the occurrence time stamp from the storage space. Then step S32 is executed with the current system time Tinited_currentSubtract the current Monotonic timer time Tmono_currentAnd occurrence timestamp Tmono_recordCalculating the actual occurrence time Treal. Among them, preferred isGround, refer to the following formula
Treal＝Tinited_current-Tdiff(Tmono_current，Tmono_record)
Or
Treal＝Tinited_current-(Tmono_current-Tmono_record)

s41: acquiring information of an event to be recorded from a storage space;
s42: and storing the log information of the event to be recorded, which is generated based on the actual occurrence time and the information of the event to be recorded, into a log database.
Since the information of the event to be recorded has already been recorded in the storage space, when the complete log information is generated at step S4, first, step S41 acquires the information of the event to be recorded from the storage space. Step S42 is then based on the actual time of occurrence TrealAnd step S41, generating the log information of the event to be recorded according to the acquired information of the event to be recorded, and storing the log information into a log database to provide complete log information for the event record needing to be perfected.
