Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The log time correction method, apparatus, electronic device and storage medium of the present invention are described below with reference to fig. 1 to 4.
As shown in fig. 1, the log time correction method according to the embodiment of the present invention mainly includes step 110, step 120, step 130, step 140 and step 150.
In step 110, it is determined that the baseboard management controller BMC is powered on, and a first target log of the server system is obtained from the BMC.
It will be appreciated that the baseboard management controller BMC is a separate microcontroller located on the computer motherboard for monitoring and managing system hardware and software. BMCs are widely used as a remote management solution in servers, workstations, and enterprise-level computing devices.
The BMC may monitor and record key hardware parameters such as temperature, voltage, fan speed, etc., and collect system event and alarm information. By combining with the system management software, an administrator can monitor and manage these data in real time through a remote connection.
BMCs allow administrators to remotely operate and manage computer systems over a network. Through protocols such as IPMI (Intelligent Platform Management Interface ), an administrator can restart, power control, firmware upgrade and the like under the condition that the system cannot be started normally or is unattended, and the availability and maintenance efficiency of the system are improved.
The BMC may monitor and report hardware faults or errors, such as power failures, temperature anomalies, fan failures, etc., and send alarms in time to notify an administrator. The BMC can record the system activity log including hardware faults, system events, user operations and the like, and provides convenience for system fault investigation and audit.
BMCs are typically composed of a separate processor, memory, network interface, and management firmware. The BMC is designed to run isolated from the main operating system to ensure that an administrator can access and manage the server remotely even when the system fails or fails to boot. BMC provides overall control and management of the computer system, enhancing reliability, stability and remote manageability of the system.
The first target log includes a corresponding initial timestamp. During the BMC start-up, when the BMC runs until it receives the BIOS start-up time, the BMC time is displayed incorrectly, typically a time several years ago. The first target log timestamp recorded during this time is also incorrect. When the log is queried, the time stamp of the log in the time period is represented by a 'Pre-init time stamp', namely an initial time stamp, rather than an actual time stamp, and the time stamp log is unfavorable for problem analysis and positioning.
Step 120, under the condition that the real-time clock chip RTC is determined to work normally, acquiring first time information from the RTC.
It can be appreciated that the log time correction method of the embodiment of the present invention is applied to a server system including an RTC.
The RTC is a real time clock chip, also known as an RTC module. The real-time clock chip is an integrated circuit, mainly composed of a crystal oscillator, a clock circuit and a counter, and is used for providing time and date information required by the system and keeping the information after the system is shut down or power down. Meanwhile, the device can realize the functions of dormancy wakeup and the like. It will be appreciated that the first time information provided by the RTC is coordinated universal time, UTC time, which may differ from the time zone local to the server system by some amount. UTC is a unified time standard in seconds based on an atomic clock. Although UTC time is a global standard time, it does not take into account regional special time adjustments such as daylight savings time. Therefore, in calculating the function of the time concerned, the local time to the region where it is located is required to perform the conversion.
Step 130, converting the first time information into second time information.
In this embodiment, the second time information is local time zone time, and the first time information obtained from the RTC is converted into the second time information, that is, the local time zone time, so that the time of the BMC is more convenient to use.
And step 140, performing time synchronization on the time of the BMC based on the second time information.
After the second time information is obtained, the time of the BMC is synchronized, so that the BMC is switched to more accurate local time zone time.
It will be appreciated that since the BMC is typically time synchronized by the basic input output system BIOS, the BMC may be configured in advance.
The second time information may be specially packaged, for example, a time synchronization tag may be set on a data packet of the second time information, where the data packet is received and the time synchronization tag is identified when the BMC is not connected to the internet, and the BMC may automatically perform time synchronization according to the received second time information.
And step 150, correcting the initial timestamp of the first target log based on the time of the BMC after time synchronization to obtain a second target log.
It can be appreciated that the BMC may correct the initial timestamp of the first target log according to the synchronized time and the synchronized accurate time, so as to obtain the second target log with an accurate timestamp.
According to the log time correction method provided by the embodiment of the invention, the accurate coordinated universal time is obtained from the real-time clock chip which normally works, and then the coordinated universal time is converted into the local time zone time to perform time synchronization on the BMC, so that the BMC can correct the initial timestamp in the obtained first target log, further a second target log with the correct timestamp can be obtained, and management maintenance personnel can conveniently analyze and position the fault of the server system in the starting process of the BMC.
In some embodiments, as shown in fig. 2, after correcting the initial timestamp of the first target log based on the time of the BMC after time synchronization to obtain the second target log, the log time correction method in the embodiment of the present invention further includes step 210, step 220, step 230, and step 240.
In step 210, it is determined that the BMC is connected to the internet, and the third time information is acquired from the internet through the network time protocol service.
The implementation of a BMC that connects to the Internet and obtains time information from the Internet through a network time protocol service typically involves the following procedure.
The BMC may be configured first to have a network connection accessible via the Internet. For example, the network interface of the BMC and related parameters such as IP address, subnet mask, gateway, etc. may be configured first.
In the setting of the BMC, a time server NTP address to be used as a network time protocol service is specified. Common NTP servers include some common NTP servers and some NTP servers provided by a particular organization or organization.
On this basis, the BMC communicates with the designated NTP server using the NTP protocol. The BMC sends a time synchronization request to the NTP server and receives third time information returned from the server, wherein the third time information is the standard time of the external network.
Step 220, comparing the third time information with the time of the BMC after the time synchronization.
According to the third time information returned by the NTP server, the BMC compares the time after the time synchronization from the RTC.
In step 230, when the time of the BMC after the time synchronization does not coincide with the third time information, the time of the BMC is re-synchronized based on the third time information.
When the time of the BMC after the time synchronization from the RTC is inconsistent with the third time information, the second time information obtained based on the RTC is not accurate enough, and the BMC can automatically apply the third time information to the system clock and the local time setting. In this way, the clock of the BMC will be synchronized with the time of the NTP server and maintain accuracy.
Step 240, correcting the timestamp of the second target log based on the time of the BMC after the re-time synchronization, to obtain a third target log.
On the basis, correcting the time stamp of the second target log again to obtain a third target log, and further guaranteeing the accuracy of the time stamp of the log.
In this embodiment, the standard time of the synchronous extranet is obtained through the internet, and the accuracy of the second time information obtained from the RTC can be determined, so that the abnormality of the RTC time or the abnormality in the local time zone time conversion process can be identified, and the accuracy of the BMC time can be improved.
In some embodiments, after correcting the timestamp of the second target log based on the time of the BMC after the re-time synchronization to obtain the third target log, the log time correction method according to the embodiment of the present invention further includes: and acquiring external network standard time from the Internet through network time protocol service according to the target frequency, comparing the external network standard time acquired each time with the BMC time, and performing time synchronization on the BMC time based on the external network standard time under the condition that the BMC time is inconsistent with the external network standard time.
It will be appreciated that the target frequency may be set as desired, and is not limited herein. The standard time synchronization can be periodically acquired from the external network NTP server according to the target frequency and can be synchronized into the BMC, so that the time in the BMC and the RTC can be calibrated.
In some embodiments, determining that the real time clock chip RTC is operating properly includes the following process.
The RTC voltage data after the BMC is powered on and started may be obtained by the RTC voltage detection circuit. The RTC voltage data comprises a plurality of voltage values acquired by the RTC voltage detection circuit at different moments.
It can be understood that an independent battery or capacitor is provided in the RTC as an independent power source to supply power, and when the power source of the main board is turned off or the power is turned off, the real-time clock chip is automatically switched to the independent power source to keep running. In this case, the real time clock chip can still continue to calculate the time and save it in the chip memory. When the server is restarted, the real-time clock chip can be automatically switched back to the main board power supply from the independent power supply, and the time information stored before is restored to the system. This ensures that time information is not lost due to system shutdown or power loss.
For monitoring the power state of the RTC, a voltage detection circuit is arranged in the RTC, and the BMC can acquire a voltage value according to a data interface such as an I2C/SPI interface.
Based on the data, the RTC voltage data is analyzed according to the time sequence, and the voltage extreme value and the change rate of the RTC are determined.
The voltage extremum of the RTC includes a voltage maximum and a voltage minimum during a period of time after the BMC is started.
It will be appreciated that the RTC is able to accurately maintain recorded time information even in the event of a power failure or impending battery depletion due to its high accuracy and low current consumption. However, when the RTC power fails, the voltage may dip or rise suddenly, and the power management module in the RTC is in the protection chip to power-off the RTC and isolate the RTC, so that the RTC is powered off.
In this embodiment, the preset RTC voltage condition may be set according to the working reality of the RTC and the power supply, where the preset RTC voltage condition includes the range of the RTC voltage and the range of the change rate.
Only in the voltage range and the change rate range included in the RTC voltage condition, the RTC will normally operate. Under the condition that the voltage extreme value and the change rate meet the preset RTC voltage condition, the real-time clock chip RTC is determined to work normally.
In this embodiment, by determining the voltage of the RTC, it may be determined that the RTC is working normally, so as to ensure that the first time information obtained from the RTC is accurate, thereby improving the accuracy of the time synchronized by the subsequent BMCs.
In some embodiments, determining that the baseboard management controller BMC is powered up includes detecting an electrical signal on a power line between the BMC and the server system, and determining that the BMC is powered up if the electrical signal is continuously detected from the power line for more than a target length of time.
The BMC in the server system is powered by a 5V or 3.3V power supply on the motherboard. These power sources are generated by a server power module, commonly referred to as a system power source or PSU. When the server normally operates, the BMC can obtain electric energy from a system power supply through a rectifying circuit on the main board and provide power for the BMC by utilizing part of the electric energy.
Therefore, whether the BMC is powered on or not can be determined by detecting an electric signal of a power line between the BMC and the server system, and the conditions of cold start and the like under abnormal conditions can be discharged by setting a target duration.
In some embodiments, the first time information is obtained from the RTC, including receiving, by the BMC, a wake-up time signal sent by the RTC, and receiving, by the BMC, the first time information sent by the RTC if the wake-up time signal sent by the RTC is received by the BMC.
It should be noted that when the server system is completely turned off or in a sleep state, all power sources are turned off by the motherboard, and at this time, the BMC cannot obtain power from the system power source and cannot obtain time information from the RTC. Therefore, in order to trigger the BMC to update the time after the incoming call, the BMC and the RTC may be configured, and after the server system is powered on, a wake-up time signal is sent to the BMC through the RTC.
When the BMC receives the wake-up time signal sent by the RTC, the BMC receives the first time information sent by the RTC, and further, after the BMC is started, the time information can be obtained by the RTC.
In some embodiments, the initial timestamp of the first target log is corrected based on the time of the BMC after the time synchronization to obtain a second target log, including the following procedures.
The third target log received from the server management software may be filtered from the first target log to obtain a fourth target log.
It should be noted that, the BMC acquires the hardware running state information through the sensors of the monitoring motherboard and each component, and judges and analyzes the hardware running state information, and if any error, fault or abnormality is found, the BMC immediately generates a corresponding log and records a timestamp, so as to help the administrator to quickly locate the problem.
In some scenarios, the BMC may also timely acquire and process reports from server management software, such as IPMI and SNMP, by means of its independence of operation in a local network outside the operating system environment and a preset behavior rule, where the server management software may nano-tube logs of other computing hardware of the server system local network where the BMC is located, i.e. the third target log. These computing hardware do not need to make corrections because the third target log is time stamped correctly without a power outage.
In this case, the initial timestamp of the fourth target log is corrected based on the time of the BMC after the time synchronization to obtain a fifth target log, and then the third target log and the fifth target log are determined as the second target log.
In the present embodiment, the third target log having the correct time stamp is excluded, and the time stamp is corrected, so that the processing efficiency can be improved.
