Please refer to FIG. 1 , which shows a system architecture diagram of a temperature monitoring method applicable to this application. In FIG. 1 , a plurality of rows of cabinets 101 arranged parallel to each other in a data center are shown, and a plurality of racks arranged in a cross manner may be arranged on the cabinets 101 , and a server 102 may be arranged on each rack. Servers 102 belonging to the same cabinet 101 can be connected in a wired manner (such as TCP/IP), and multiple cabinets 101 can communicate through a switch 104 . In addition, a monitoring server 103 is also shown, and the monitoring server 103 is used to monitor the temperatures of multiple servers 102 .

Please refer to FIG. 2 , which shows a flow 200 of an embodiment of the temperature monitoring method according to the present application. The method includes the following steps:

In step 201, the monitoring information of the server in the data center is acquired, and the monitoring information includes the air inlet temperature and location information of the server.

In this embodiment, the monitoring information of the server in the data center can be acquired through the monitoring server. The monitoring information includes the air inlet temperature and location information of the server, and the air inlet temperature is the corresponding temperature when the cold air generated by the air conditioner in the data center flows through the server detected by the temperature sensor installed on the server substrate. The detected inlet air temperature can be used to indicate the current operating temperature of the service. In this embodiment, the temperature sensor disposed on the server substrate may be used to detect the intake air temperature of the server, for example, the temperature sensor may be directly disposed on the baseboard management controller of the server. In this embodiment, the temperature of the cold air generated by the air conditioner in the data center flows through the server to characterize the inlet air temperature of the server. The air inlet temperature avoids the influence on the temperature detection results due to factors such as unsmooth airflow organization in the data center and partial airflow blocked by building factors, so that it can more accurately reflect the actual working temperature of the server. In this embodiment, the location information of the server may be a serial number pre-assigned to the server in the cabinet. For example, if multiple servers are arranged crosswise in the cabinet, each server may be assigned a serial number in advance according to the arrangement order, and the serial number may be used as the location information of the server.

In this embodiment, a script for collecting the data of the inlet air temperature may be pre-configured on the server in the data center, and the script may be used to upload the collected inlet air temperature and the location information of the server to the monitoring server. For example, when the server runs the Linux operating system, a Linux shell script for reading the air inlet temperature data can be preset on the server in the data center. When the temperature sensor installed on the server substrate is used to collect the inlet air temperature, the Linux Shell script can be used to read the temperature signal output by the temperature sensor in a loop to obtain the server’s inlet air temperature, and the Linux Shell script will convert the air inlet temperature to The temperature and the location information of the server are sent to the monitoring server.

In some optional implementation manners of this embodiment, the location information of the server includes: cabinet identification information and rack identification information. In this embodiment, the cabinet identification information may be represented by a serial number. For example, each cabinet in the data center may correspond to a serial number representing the row number of the cabinet in the data center. The rack identification information can be represented by a two-dimensional coordinate. In the cabinet, multiple servers are arranged crosswise, and the position of each rack in the cabinet can be represented by a two-dimensional coordinate. Wherein, the abscissa indicates the number of rows of the rack in the cabinet, and the ordinate indicates the number of columns of the rack in the cabinet. The cabinet to which the server belongs and the position in the cabinet can be determined according to the cabinet information and the rack information.

In some optional implementations of this embodiment, obtaining the monitoring information of the server in the data center includes: obtaining the monitoring information of the server through the master control server, and the master control server selects from the servers in the data center in advance; receiving the data sent by the master control server The monitoring information of the server. In this embodiment, one server may be selected in advance from the servers in the data center as the master control server, and the master control server may be used to obtain the air inlet temperatures of other servers in the data center. The main control server can be used to obtain the air inlet temperature and location information of other servers in the data center through a Linux Shell script at regular intervals, and then send the acquired air inlet temperature and location information of other servers to the monitoring server.

In some optional implementation manners of this embodiment, the monitoring information further includes at least one of the following: motherboard information, hard disk information, memory information, fan number information, and processor operating temperature information.

Step 202, based on the location information, determine servers belonging to the same cabinet;

In this embodiment, servers belonging to the same cabinet may be determined according to the location information of the servers in the acquired monitoring information. For example, when the location information is the serial number of the cabinet to which it belongs, servers with the same serial number in the location information may be determined as servers belonging to the same cabinet.

Step 203, determine a local hotspot server based on the air inlet temperature.

In this embodiment, the local hotspot server is a server whose air intake temperature is higher than that of other servers belonging to the same cabinet. In this embodiment, after the air inlet temperature of each server in the data center is acquired, a local hotspot server, that is, the server with the highest air inlet temperature corresponding to the servers belonging to the same cabinet can be determined. In this embodiment, when the server monitoring information is received, the servers belonging to the same cabinet may be determined according to the cabinet information in the monitoring information. Then, by comparing the inlet air temperature of servers belonging to the same cabinet, the server with the highest air inlet temperature can be determined as the local hotspot server, and the rack information in the monitoring information can be further used to determine that the local hotspot server is in the cabinet to which it belongs s position. In this embodiment, after the local hotspot servers in multiple cabinets in the data center are determined, the central hotspot server may also be determined, that is, the corresponding server with the highest inlet air temperature in the entire data center.

Step 204, based on the air inlet temperature and location information of the local hotspot server, adjust the air supply temperature.

In this embodiment, the air supply temperature is the corresponding temperature when the cold air generated by the air conditioner in the data center flows through the cabinet where the local hotspot server is located. In this embodiment, after the local hotspot server in the data center is determined, the air supply temperature of the air conditioner in the data center may be adjusted based on monitoring information corresponding to the local hotspot server.

Please refer to FIG. 3 , which shows a schematic diagram of adjusting the air supply temperature of the air conditioner in the data center. The following describes the process of adjusting the air supply temperature of the air conditioner in the data center according to the air inlet temperature and position of the local hotspot server in combination with FIG. In the server on the server, after the server is cooled down, it is discharged through the hot aisle 303 . In this embodiment, the cold aisle 302 may be the aisle arranged at the bottom of the cabinet in the data center, and the hot aisle 303 may be the aisle arranged at the top of the cabinet in the data center. When the inlet air temperature of the local hotspot server is greater than the temperature threshold, the air supply temperature of the air conditioner 301 corresponding to the cabinet can be lowered according to the inlet air temperature, thereby cooling the server in the cabinet. At the same time, the air inlet temperature of the local hotspot server can be detected in real time, and when it is detected that the air inlet temperature of the local hotspot server is lower than the temperature threshold, the reduction of the air supply temperature of the air conditioner 301 can be stopped. In this embodiment, since the temperature of the cold air generated by the air conditioner 301 of the data center flows through the server to characterize the inlet air temperature of the server, the detected inlet air temperature is more accurate. Further, the detected inlet air temperature can be used The temperature adjusts the air supply temperature of the air conditioner 301 more precisely.

In some optional implementations of this embodiment, adjusting the air supply temperature based on the air inlet temperature and location information of the local hotspot server includes: determining the sub-area of the local hotspot server in the cabinet based on the location information of the local hotspot server , and determine the preset weighted value corresponding to the sub-area; calculate the difference between the inlet air temperature and the air supply temperature of the local hotspot server; use the product of the difference and the preset weighted value as the temperature change; based on the temperature change, adjust the air supply wind temperature. In this embodiment, it is considered that the cold air generated by the air conditioner in the data center is also affected by the air flow in the data center when it flows through the cabinets, so that the temperature of the cold air generated by the air conditioner flows through the servers in the cabinets is different. Therefore, in this embodiment, the cabinet may be divided into multiple sub-areas in advance, each sub-area corresponds to multiple servers, and each sub-area corresponds to a preset weighted value. When performing temperature adjustment, first determine the sub-area to which the local hotspot server belongs in the cabinet, and determine the preset weight value corresponding to the sub-area, which is used to represent the cold air generated by the air conditioner in the data center flowing through the sub-area The ratio of the temperature change of the server at that time. Then, the difference between the inlet air temperature and the air supply temperature of the local hotspot server can be calculated; the product of the difference and the preset weighted value is used as the temperature variation. Finally, the air supply temperature is adjusted based on the amount of temperature change. For example, the temperature of the cool air generated by the air conditioner in the data center can be lowered according to the amount of temperature increase.

In some optional implementations of this embodiment, it also includes: judging whether the inlet air temperature of the local hotspot server is greater than a preset temperature threshold; if so, generating alarm information, and displaying the alarm information and monitoring information of the local hotspot server. In this embodiment, when it is detected that the air inlet temperature of the local hotspot server is greater than the preset temperature threshold, an alarm message can be displayed on the monitoring server, and the current air inlet temperature of the local hotspot server and the location of the local hotspot server in the cabinet can be displayed. where you are. In this way, the operation and maintenance personnel can obtain the air inlet temperature of the local hotspot server in the data center in real time, and reduce the air supply temperature of the air conditioner in time according to the air inlet temperature of the local hotspot server, thereby reducing the risk of server downtime.

Please refer to FIG. 4 , which shows a schematic diagram of the effect of displaying monitoring information of a local hotspot server on the monitoring server. In FIG. 4 , the detected air intake temperatures of the local hotspot servers in multiple cabinets and the positions of the local hotspot servers in the cabinets to which they belong are shown. In addition, the status of the local hotspot server can also be displayed at the same time. Therefore, the operation and maintenance personnel can determine whether to adjust the air supply temperature of the air conditioner in the data center according to the state of the local hotspot server.
