Description

Periodic event recording method

The invention relates to a periodic event recording method, in particular to a periodic event recording method for a power supply.

Generally speaking, the server is equipped with a baseboard management controller (Baseboard Management Controller, BMC), which can be used to monitor the status of the sensor to generate corresponding event records. For example, the baseboard management controller compares the current sensor status with the relevant data parameters in the sensor data record (SDR). If the two match, an event log file is generated.

PSU predictive failure (PSU predictive failure) is an alarm state, which is mainly used to prompt the user that the power supply is about to be damaged, so that the user can detect the timing of replacing the power supply. Since the number of event log files that can be stored by the server is limited, when the number reaches the upper limit, the old event log files will be overwritten by the new event log files.

If the baseboard management controller detects that the power supply predicts a fault state, it will record the occurrence of an event, that is, generate an event log file. If the user does not see the event log file of the power supply in real time, the event log file will be overwritten by other event log files and the user cannot be effectively reminded.

The present invention proposes a periodic event recording method, which is mainly to generate an event record periodically when the substrate management controller detects the predicted failure state of the power supply to repeatedly warn the user to replace the power supply.

According to one embodiment of the present invention, a periodic event recording method is disclosed, which includes the following steps. The baseboard management controller reads the power supply register to obtain the information related to the power supply; the baseboard management controller confirms the logic state of the power supply according to the information to determine whether the power supply is detected Predict failure status, and the baseboard management controller monitors the preset logic variables; when the baseboard management controller detects the predicted failure status of the power supply, an event record is generated accordingly; the baseboard management controller determines whether the preset logic variable is True; when it is judged that the preset logic variable is true, the baseboard management controller selectively executes timing tasks to determine whether to generate a control command; and the baseboard management controller adds another event record according to the control command, where the other The event record is different from the aforementioned event record.

In summary, in the periodic event recording method provided by the present invention, the substrate management controller is used to determine whether the power supply is detected to have a predicted failure state. If there is, the baseboard management controller first generates an event record, and determines whether to add the next event record through the timing task. The baseboard management controller generates event records about the power supply in a periodic manner, which can avoid being covered by other types of events, and achieve the purpose of repeatedly providing information about the power supply's failure to the user, thereby driving the user Replace the power supply as soon as possible.

The above description of the disclosure and the following description of the embodiments are used to demonstrate and explain the spirit and principle of the present invention, and provide a further explanation of the scope of the patent application of the present invention.

The following describes in detail the detailed features and advantages of the present invention in the embodiments. The content is sufficient for any person skilled in the relevant art to understand and implement the technical content of the present invention, and according to the contents disclosed in this specification, the scope of patent application and the drawings Anyone skilled in the relevant art can easily understand the purpose and advantages of the present invention. The following examples further illustrate the views of the present invention in detail, but do not limit the scope of the present invention in any way.

Please refer to FIGS. 1 and 2 together. FIG. 1 is a functional block diagram of a server according to an embodiment of the present invention, and FIG. 2 is a periodic event record according to an embodiment of the present invention. Method flowchart of the method. The periodic event recording method of FIG. 2 can be executed by the server of FIG. 1. As shown in FIG. 1, the server 1 includes a baseboard management controller (Baseboard Management Controller, BMC) 10 and a power supply 12. In this embodiment, the baseboard management controller 10 communicates with the power supply 12 through a power management bus (Power Management Bus, PMbus). In practice, the server 1 may include other basic components, such as a processor, a memory, etc., which are conventional technologies in the art and will not be repeated here.

The method of the present invention is shown in FIG. 2. In step S201, the substrate management controller 10 of the server 1 will first perform an initial program to enable various functions of the substrate management controller 10. Next, in step S202, the board management controller 10 reads the register 121 in the power supply 12 to obtain information related to the power supply 12. In a practical example, the information is one of temperature information, input/output power consumption information, input/output voltage information, or status information of the power supply. In practice, the power supply 12 has a register 121, where the register 121 defines a message about the operation of the power supply 12, such as the aforementioned temperature information, input/output power consumption information, input/output voltage information, or the status of the power supply Information etc. During actual operation, the BMC 10 will read the register 121 in the power supply 12 at regular intervals (for example, every second) to continuously obtain this information. In this example, only one register is used as an example. However, in practice, the power supply 12 may have multiple registers.

In step S203, the board management controller 10 confirms the status of the logical sensor of the power supply 12 according to the information to determine whether the PSU predictive failure status is detected. Specifically, when the board management controller 10 obtains the information of the register 121 in the power supply 12, it will confirm the status of the logical sensor corresponding to this information according to this information, and then determine whether the predicted failure occurs in the power supply 12 status. In step S204, when the substrate management controller 10 determines that the predicted failure state of the power supply 12 is detected, an event log is generated correspondingly. In practice, if the substrate management controller 10 confirms that the bit corresponding to this message is 1, it determines that the predicted failure state of the power supply 12 is detected. On the contrary, when the bit corresponding to this message is 0, it is determined that the predicted failure state of the power supply 12 is not detected.

In addition to step S203, on the other hand, the method further includes: in step S205, the substrate management controller 10 monitors the preset logical variable. In step S206, the substrate management controller 10 selectively executes the timing task according to the monitoring result of the preset logical variable to determine whether to generate the control command. If the substrate management controller 10 determines to generate a control command according to the foregoing monitoring result, then in step S207, the substrate management controller 10 adds another event record according to the control command. In this embodiment, the another event record and the foregoing event record are two independent and different event records. In the method of the present invention, on the one hand, the baseboard management controller 10 may set the preset logical variable to TRUE according to the predicted failure state. On the other hand, when the substrate management controller 10 monitors that the preset logical variable is TRUE, it determines that the timing task needs to be performed. Then, the baseboard management controller 10 determines whether to generate a control command to add another event record according to the result of the timing task. The operation mode of the board management controller 10 in the method of the present invention will be described in detail in the following paragraphs.

Please refer to FIG. 3A and FIG. 3B together. FIG. 3A and FIG. 3B are detailed method flowcharts of a periodic event recording method according to an embodiment of the invention. As shown, step S203 "Confirming the logic sensor state of the power supply 12 based on this information with the board management controller 10 to determine whether the predicted failure state of the power supply 12 is detected" includes step S2031 With S2032. In step S2031, the board management controller 10 compares this information with preset parameters in the memory of the board management controller 10 to generate a comparison result. In step S2032, the substrate management controller 10 determines whether the predicted failure state of the power supply 12 is detected according to the comparison result. In detail, the baseboard management controller 10 can compare the information in the read register 121 with the preset parameters stored in the sensor data record 102 (SDR) of the baseboard management controller 10. If the comparison result shows that the two match, the substrate management controller 10 determines that the predicted failure state of the power supply 12 is detected, and accordingly generates an event record.

In one embodiment, the “when the substrate management controller 10 detects a predicted failure state of the power supply 12 corresponding to the event record” described in step S204 includes steps S2041 and S2042. In step S2041, the board management controller 10 sets the logic sensor state to the failure state. In step S2042, the baseboard management controller 10 sets the preset logical variable to TRUE. That is, when the substrate management controller 10 confirms that the predicted failure state of the power supply 12 is detected, it will set the logic sensor state to the failure state and set the preset logic variable to TRUE, which can correspond to Generate the aforementioned event record. In another embodiment, the method further includes step S208. When the board management controller 10 does not detect the predicted failure state of the power supply 12, in step S208, the board management controller 10 sets the sensor state to a non-failed state and sets the preset logic variable to FALSE, and then return to the step of using the board management controller 10 to confirm whether the predicted failure state of the power supply 12 is detected.

In one embodiment, the "monitoring of preset logic variables with the board management controller 10" shown in step S205 includes steps S2051 and S2052. In step S2051, the substrate management controller 10 detects the preset logic variable. In step S2052, the board management controller 10 determines whether the preset logical variable is set to true. In other words, the baseboard management controller 10 continuously detects the preset logical variables in the monitoring process. When the board management controller 10 detects the predicted failure state of the power supply 12 and sets the preset logical variable to TRUE, at the same time, the board management controller 10 can learn the preset by the aforementioned monitoring procedure The logical variable is true.

In one embodiment, step S206 of "using the board management controller 10 to selectively execute a timing task to determine whether to generate a control command according to the monitoring result of the preset logical variable" includes steps S2061 to S2064. When the baseboard management controller 10 determines that the preset logical variable is set to true, in step S2061, the baseboard management controller 10 executes a timing task to start accumulating time. In step S2062, the substrate management controller 10 determines whether the accumulated timing reaches a preset time. When the accumulated timing of the board management controller 10 reaches the preset time, in step S2063, the board management controller 10 generates a control command. In practice, as shown in FIG. 1, the baseboard management controller 10 has a timer 101 inside, which can be used to perform the timing task. Taking a practical example to illustrate the above steps, when the substrate management controller 10 determines that the preset logical variable is set to true, it means that the power supply 12 is in the state of impending failure, so the substrate management controller 10 will correspondingly generate an event record, that is, The first event record. At the same time, the baseboard management controller 10 will enable the timer 101 to start timing. For example, the timer 101 increments by 1 every second and starts accumulating sequentially from 0.

Suppose that in this example, the preset time is set to 259200 seconds (that is, 3 days). When the timer 101 counts up from 0 to 259200, the baseboard management controller 10 correspondingly generates a control command, and through the application The interface (Application Programming Interface, API) sends this control command to self. Then, as shown in step S207, the substrate management controller 10 can add another event record according to the control command, that is, the second event record. The second event record and the aforementioned first event record are two independent event records generated at different times. The preset time described in this example is for illustration only. The present invention is not limited to this preset time, and the user can determine the length of the cycle according to actual needs.

In other words, in the method of the present invention, if the user does not replace the power supply 12 due to the failure to notice the first event record, the accumulated time of the timer 101 may reach a preset time (for example, 3 days) to allow the substrate management The controller 10 generates a second event record according to the control command, which is used to warn the user again that the power supply 12 should be replaced. By reminding the user repeatedly in this periodic event recording mode, it is possible to avoid that the first event record is overwritten by other types of event records, causing the user to be unaware of the information that the power supply 12 is about to fail. In actual operation, after the baseboard management controller 10 adds the second event record, the timer 101 returns to zero and returns to the step of determining that the preset logical variable is set to true. If the user has not yet replaced the power supply 12, the baseboard management controller 10 will generate a third event record in the next cycle (ie, the count reaches 259200 seconds again). On the contrary, if the user replaces the power supply 12 before the accumulated time of the timer 101 reaches the preset time, the timer 101 stops counting and resets the time to zero, and returns to step S2052. At this time, since the power supply 12 has been replaced and the predicted failure state cannot be detected, the board management controller 10 sets the sensor state to the non-failure state and sets the preset logical variable to FALSE.

In one embodiment, when the substrate management controller 10 determines that the preset logical variable is set to false, in step S2064, the substrate management controller 10 will not perform this timing task (the timer 101 returns to zero), and returns It is the step for the substrate management controller 10 to determine whether the preset logical variable is true. That is to say, the preset logical variable is set to be a pseudo representative power supply 12 and is in a non-failed state, so the timer 101 does not need to be timed to generate an event record to remind the user to replace it.

In summary, in the periodic event recording method provided by the present invention, the baseboard management controller is mainly used to determine whether a power supply failure condition is detected. If there is, the baseboard management controller first generates an event record, and determines whether to add the next event record through the timing task. The baseboard management controller generates event records about the power supply in a periodic manner, which can avoid being covered by other types of events, and achieve the purpose of repeatedly providing information about the power supply's failure to the user, thereby driving the user Replace the power supply as soon as possible.
