[0052] The following describes exemplary embodiments of the present invention with reference to the accompanying drawings. Various details of the embodiments of the present invention are included to assist understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, descriptions of well-known functions and structures are omitted below for clarity and conciseness.

[0053] In the prior art, the operating system monitors the load parameters of computer hardware and determines whether to degrade the application service according to the load parameters. For example, the operating system monitors the CPU usage rate, and when the CPU usage rate exceeds 90%, it notifies the application service registration center to take the application service offline.

[0054] However, if the computer experiences power failure or restart, etc., the operating system cannot notify the application service registration center to take the application service offline in time.

[0055] In view of this, as Figure 1 shown, the embodiments of the present invention provide an application service degradation method, which is applied to BMC and includes:

[0056] Step 101: Obtain hardware information.

[0057] BMC is independent of the hardware and the operating system and has an independent computing chip, storage structure, battery power supply, network interface, etc. In the embodiments of the present invention, BMC can interact with different hardware to obtain information of different hardware. Specifically, the hardware can include: disks, network cards, fans, power adapters, bus controllers, and CPUs, etc. The hardware information can include: CPU temperature, fan speed, voltage of the power adapter, etc. The hardware information can be actively reported by the hardware or actively obtained by BMC according to actual needs.

[0058] Step 102: Determine the degradation type corresponding to the hardware information according to the hardware information and the preset hardware conditions corresponding to the degradation type.

[0059] In an embodiment of the present invention, different degradation types correspond to different hardware conditions. The obtained hardware information is matched with various hardware conditions to determine the degradation type corresponding to the hardware information. The degradation types include: current limiting and offline. Current limiting includes restricting interface traffic and restricting log output. For example, reducing the traffic of a certain interface. Offline means stopping the service provided by the interface.

[0060] It should be noted that according to the hardware information, it may also be determined that the application service does not need to be degraded, so the application service runs in the current state. The embodiments of the present invention only focus on the cases where degradation is required.

[0061] Step 103: Degrade the application service according to the degradation type corresponding to the hardware information.

[0062] This method is applied to the BMC. Since the BMC is independent of the hardware and the operating system, even if the computer suddenly loses power or is forced to restart, this method can still degrade the application service in a timely manner. Moreover, this method can implement different degradation types according to the hardware information. For example, interface current limiting, application service offline, etc., and can provide a more refined degradation scheme according to the load situation of the hardware, improving the reliability of the application service.

[0063] In an embodiment of the present invention, the hardware information includes: event logs;

[0064] Determining the degradation type corresponding to the hardware information according to the hardware information and the preset hardware conditions corresponding to the degradation type includes:

[0065] Matching the event type in the event log with the event types corresponding to the degradation types to determine the degradation type corresponding to the event log.

[0066] The embodiments of the present invention can check whether the hardware reports event logs (Event Log) at regular intervals, for example, every 5 seconds. The event log includes an event identifier and an event type. Among them, the event type includes info (general information), warning (warning), and error (serious exception). The event identifier is used to identify the source of the event log.

[0067] In the embodiments of the present invention, the hardware condition is the event type corresponding to the downgrade type. The correspondence between the event type and the downgrade type can be determined according to actual requirements. For example, if the event type is info, the application service maintains its existing state; if the event type is warning, the corresponding downgrade type is traffic limiting; if the event type is error, the corresponding downgrade type is offline. In actual application scenarios, the downgrade type corresponding to the event type error can also be adjusted to traffic limiting, or the downgrade type corresponding to the event type warning can be adjusted to offline.

[0068] For the same event type of different hardware, it can correspond to the same downgrade type, or it can also correspond to different downgrade types to adapt to the differences of different hardware. For example, the downgrade type corresponding to the event type error of the CPU is offline, and the downgrade type corresponding to the event type error of the network card is traffic limiting.

[0069] The embodiments of the present invention can execute corresponding downgrade policies on the application service according to the event type. Since the event log can reflect the operating state of the hardware, the embodiments of the present invention can more effectively adjust the application service

[0070] In one embodiment of the present invention, the hardware information includes: the health indicators of the hardware;

[0071] Determining the downgrade type corresponding to the hardware information according to the hardware information and the preset hardware conditions corresponding to the downgrade type includes:

[0072] Matching the health indicators of the hardware with the health indicator range corresponding to the downgrade type to determine the downgrade type corresponding to the health indicators of the hardware.

[0073] The health indicators of the hardware are used to measure the health degree of the hardware, including: CPU temperature, network card inflow and outflow rate, voltage of the power adapter, fan speed, etc. In the embodiments of the present invention, the hardware condition refers to the health indicator range, such as the CPU temperature range, the power adapter voltage range, etc. Different downgrade types correspond to different health indicator ranges. For example, the CPU temperature range corresponding to traffic limiting is (60°C - 90°C), and the CPU temperature range corresponding to offline is greater than 90°C.

[0074] The embodiments of the present invention adjust the application service based on the health degree of the hardware, taking into account the differences in the health degrees of different hardware, and adjusting the application service more timely to improve the reliability of the application service.

[0075] In one embodiment of the present invention, the downgrade type corresponding to the hardware information is traffic limiting;

[0076] Downgrading the application service according to the downgrade type corresponding to the hardware information includes:

[0077] Send the hardware information to the application service so that the application service can limit the interface traffic according to the hardware information and the preset interface traffic limiting policy.

[0078] The application service can limit the traffic of some interfaces of the application service according to the pre-configured interface traffic limiting policy, which not only considers the running state of the hardware but also ensures the availability of the application service.

[0079] In the embodiment of the present invention, sending the hardware information to the application service includes:

[0080] Send the hardware information to the application service through ipmitool.

[0081] In the embodiment of the present invention, the existing ipmitool is used to send the hardware information to the application service without the need to develop additional tools. Ipmitool runs in the operating system and sends the hardware information to the application service based on the semaphore of the operating system to prevent excessive output of hardware information and reduce the performance of the application service.

[0082] In an embodiment of the present invention, the degradation type corresponding to the hardware information is traffic limiting;

[0083] Degrading the application service according to the degradation type corresponding to the hardware information includes:

[0084] Send the hardware information to the application service so that the application service can limit the log output according to the hardware information and the preset log degradation policy.

[0085] In the embodiment of the present invention, the application service can slow down or terminate the log output because the log output consumes the resources of the hardware. In the case of high hardware load, the log output can be reduced to ensure that the application service processes business requests. In the embodiment of the present invention, the hardware information is sent to the application service through ipmitool.

[0086] In an embodiment of the present invention, the degradation type corresponding to the hardware information is offline;

[0087] Further include: obtaining the IP and interface identifier of the application service from the operating system;

[0088] Degrading the application service according to the degradation type corresponding to the hardware information includes:

[0089] Send the IP and interface identifier of the application service to the application service registration center so that the application service registration center can take the interfaces of the application service offline according to the IP and interface identifier of the application service.

[0090] When there are relatively serious problems with the hardware, the application service cannot provide services externally. At this time, the application service needs to be taken offline. For example, when the CPU temperature exceeds 90°C. In the embodiments of the present invention, through ipmitool, the IP and interface identifier of the application service are obtained from the application service running in the operating system. The application service registration center can take one or more interfaces of the application service offline according to the IP and interface identifier of the application service, and the offline interfaces will terminate providing services. The embodiments of the present invention can take the interface service offline in a timely manner to avoid providing invalid services.

[0091] As Figure 2 shown, the embodiments of the present invention provide an application service degradation method, which is applied to BMC and includes:

[0092] Step 201: Obtain the IP and interface identifier of the application service from the operating system.

[0093] After the application service starts, the IP and interface identifier of the application service are provided to the application service degradation device running on the BMC through ipmitool. The application service degradation device saves the IP and interface identifier of the application service in the cache.

[0094] Step 202: Obtain the event log and the health metrics of the hardware.

[0095] This method can be implemented by a program running on the BMC. This method can obtain the event log and health metrics of hardware such as CPU, network card, disk, power adapter, fan, memory socket, etc. based on the BMC where it is located. The embodiments of the present invention are only illustrated by taking the CPU as an example.

[0096] The CPU obtains the event log and the health metrics of the CPU through the ipmi protocol. Among them, the event type of the event log is error (serious exception), and the health metric of the CPU is the CPU temperature of 95°C.

[0097] Step 203: Match the event type in the event log with the event type corresponding to the degradation type to determine the degradation type corresponding to the event log.

[0098] The preset correspondence between the event type and the degradation type includes: info (general information) corresponding to no degradation, warning (warning) corresponding to traffic limiting, and error (serious exception) corresponding to offline.

[0099] In the embodiments of the present invention, the degradation type corresponding to the event log is offline.

[0100] Step 204: Match the health metrics of the hardware with the health metric range corresponding to the degradation type to determine the degradation type corresponding to the health metrics of the hardware.

[0101] The correspondence between the pre-set CPU temperature range and the degradation type includes: when the CPU temperature is less than 60°C, there is no degradation; when the CPU temperature range is (60°C - 90°C), current limiting is performed; when the CPU temperature range is greater than 90°C, the service is taken offline.

[0102] The CPU temperature range corresponding to current limiting is (60°C - 90°C), and the CPU temperature range corresponding to taking the service offline is greater than 90°C.

[0103] In the embodiment of the present invention, the degradation type corresponding to the health indicator of the hardware is taking the service offline.

[0104] Step 205: Determine the degradation type corresponding to the hardware information according to the degradation type corresponding to the event log and the degradation type corresponding to the health indicator of the hardware.

[0105] In the embodiment of the present invention, since the hardware information includes both the event log and the health indicator of the hardware, in order to avoid inconsistent degradation types determined by the two, resulting in the inability to degrade the application service, the embodiment of the present invention can also pre-set the priorities of the event log and the health indicator of the hardware. If the degradation types determined by the two are different, the degradation type corresponding to the hardware information with the higher priority shall prevail.

[0106] Step 206: Send the IP and interface identifier of the application service to the application service registration center, so that the application service registration center takes offline the interface of the application service according to the IP and interface identifier of the application service.

[0107] The application service registration center will take offline the interface of the application service according to the IP and interface identifier of the application service. The front end will obtain the interfaces of the available application services from the application service registration center and send service requests to the interfaces of the available application services.

[0108] In the embodiment of the present invention, it is possible to determine whether it is necessary to take offline the application service according to the health indicator and event log of the hardware. This method runs on the BMC, independent of the operating system, and can take offline the application service in a timely manner.

[0109] As Figure 3 shown, the embodiment of the present invention provides an application service degradation method, which is applied to the BMC and includes:

[0110] Step 301: Obtain the IP and interface identifier of the application service from the operating system.

[0111] Step 302: Obtain the event log.

[0112] In the embodiment of the present invention, when a bad track occurs on the disk, an event log is generated, and the event type can be warning (warning).

[0113] Step 303: Match the event type in the event log with the event types corresponding to the degradation types to determine the degradation type corresponding to the event log.

[0114] The pre-set correspondence between event types and degradation types includes: info (general information) corresponding to no degradation, warning (warning) corresponding to traffic limiting, and error (severe exception) corresponding to offline.

[0115] In the embodiment of the present invention, the degradation type corresponding to the event log is traffic limiting.

[0116] Step 304: Send the event log to the application service through ipmitool so that the application service restricts the log output according to the event log and the pre-set log degradation policy.

[0117] In an actual application scenario, the application service can perform degradation according to different degradation policies. For example, it can adopt a log degradation policy to limit the log output, or it can limit the interface traffic according to the interface traffic limiting policy. The application service can determine the degradation policy corresponding to the hardware information according to the hardware type or event type, etc.

[0132] The acquisition module 401 is configured to acquire the IP and interface identifier of the application service from the operating system;

[0133] The degradation module is configured to send the IP and interface identifier of the application service to the application service registration center, so that the application service registration center takes the interface of the application service offline according to the IP and interface identifier of the application service.
