Description

A method, device and readable medium for monitoring server memory

technical field

The present invention relates to the field of servers, and more particularly, to a method, a device and a readable medium for monitoring the memory of a server.

Background technique

With the advent of the era of big data, cloud computing, and artificial intelligence, the amount of Internet business and data has increased dramatically, and data has become the foundation of many key technologies. In server systems, with the increase in the amount of data used for storage and computing, The load pressure of the server is increasing, which requires higher and higher requirements for the stability of the entire data link. In the process of data transmission, for data transmission errors on the link, a small amount of errors can be corrected through the check mechanism. If the link stability is relatively poor, or the hardware equipment on the data transmission link is damaged, transmission errors Data will be frequently and continuously accumulated, which will slightly reduce the computing performance and storage performance of the server, and in serious cases will cause the hard disk to drop and the system to go down. losses are unpredictable.

In the server system, in order to make the system run more safely and stably, the memory used must have high stability and error correction performance. The related technology is ECC (Error Correcting Code, error checking and correction). ) function memory; for ECC technology, the error of a single data can be corrected by itself and continue to be used, and the failure to correct the error of two data at the same time will cause the system to crash. With the increase of memory frequency, the requirements for signal transmission are also getting higher and higher, which will inevitably lead to an increase in the number of single data errors, but such single data errors are allowed to a certain extent, because a small amount of errors does not will affect the performance and normal operation of the system. However, if the number of ECCs is large, for example, the memory body is damaged, it will cause ECC storms in a short period of time, which will occupy more resources in a short period of time to deal with these ECC errors, which will cause the computing performance of the server. And the storage performance is reduced, which will seriously cause the hard disk to drop and the system to crash. In the current design, the ECC is monitored. If the number of ECC exceeds the BIOS threshold, an alarm will be issued and the memory will be replaced. However, a small number of ECCs do not need special treatment. This mechanism will generate a large maintenance cost; we only need to deal with ECC storms. It is enough to monitor and judge, because this ECC storm will cause performance degradation, and it is necessary to replace the memory in time. To this end, we need to actively monitor and judge the occurrence of ECC storms and reflect them in the monitoring log in time to avoid the impact on the system level caused by failure to replace them in time.

It can be seen that "first" and "second" It is only for the convenience of expression and should not be construed as a limitation to the embodiments of the present invention, and subsequent embodiments will not describe them one by one.

Based on the above objective, in a first aspect of the embodiments of the present invention, an embodiment of a method for monitoring server memory is provided. FIG. 1 shows a schematic diagram of an embodiment of a method for monitoring server memory provided by the present invention. As shown in Figure 1, the embodiment of the present invention includes the following steps:

S1. Receive and count error checking and correction information;

S2, judging whether the number of times of receiving error checking and correction information in a continuous first preset time length reaches a first threshold;

S3, in response to the number of times of receiving the error check and correction information in the continuous first preset time length reaching the first threshold, record the log information in the black box log;

S4, judging whether the log information in the black box log reaches a predetermined standard within a continuous second preset duration; and

S5. In response to the log information in the black box log reaching a predetermined standard within a second consecutive preset time period, record the log information in the BMC system log to remind the user to replace the memory.

Error checking and correction messages are received and counted. The first threshold is set in the BIOS (Basic Input Output System), the memory of the system is detected, and error checking and correction information is generated when a single data (eg, one bit) error occurs, and the BIOS receives the error checking and correction. information and counting. In some embodiments, receiving and counting the error check and correction information includes: the system repairs the memory according to the received error check and correction information.

In some embodiments, the counter may be reset to zero periodically. In some cases, since some errors can be repaired inside the system, when the frequency of data errors is not high, the system memory can be used normally. If it is not cleared, the number of times of receiving error checking and correction information always reaches the first threshold. Sometimes, in order to avoid this situation, the counter can be reset to zero every once in a while.

It is judged whether the number of times of receiving error checking and correction information within a continuous first preset time period reaches a first threshold. The log information is recorded in the black box log in response to the number of times of receiving the error checking and correction information reaching the first threshold within the continuous first preset time period. In some embodiments, in response to the number of times of receiving the error checking and correction information reaching the first threshold within the consecutive first preset time period, recording the log information into the black-box log further comprises: in response to the consecutive first When the number of times of receiving error checking and correction information within a preset time period reaches a first threshold, an interrupt is triggered, and the interrupt is sent to the BMC. After the BMC receives the interrupt, it will record the interrupt in the black box log.

It is judged whether the log information in the black box log reaches a predetermined standard within a second continuous preset time period. In some embodiments, judging whether the log information in the black box log meets a predetermined standard within a second continuous preset time period includes: judging the number of times of receiving error checking and correction information within the second continuous second preset time period whether the second threshold is reached. You can count the number of records in the black box log within a certain period of time. For example, when the number of errors reported within half an hour is greater than 5, it is considered that there is an ECC storm. In response to the log information in the black box log reaching a predetermined standard, the log information is recorded in the BMC system log to remind the user to replace the memory.

In some embodiments, the above method further includes: determining whether the memory has been replaced; and in response to the memory having been replaced, zeroing the number of times of receiving error checking and correction information.

The invention proposes a method for realizing storm monitoring through BIOS and black box log. On the basis of the original mechanism, the optimization design is carried out, and the purpose of storm monitoring is realized through double monitoring of BIOS and black box log. Specifically, first, the ECC threshold is set in the BIOS. When the threshold is reached, an interrupt will be triggered and sent to the BMC; secondly, after the BMC receives the interrupt, it will be recorded in the black box log first. At this time, the user cannot perceive any ECC error occurs; finally, count the number of records in the black box log within a certain period of time. For example, when the number of errors reported within half an hour is greater than 5, it is considered that there is an ECC storm, and it will be recorded in the system log of the BMC. At this time, the terminal The user can monitor the ECC. In this way, you can decide whether to replace the memory by checking whether there is a corresponding error in the system log of the BMC. It can not only avoid the waste of memory replacement due to a small number of ECC errors and the impact on customer business, but also ensure that when a real failure occurs, it can be handled in time, ensure the stability of system operation, and improve customer satisfaction and product competitiveness. .
