The above four cooperate with each other, and through the solution provided by this embodiment, the problems of heavy load on the server and long time-consuming requests can be solved when adjusting the log level.

In the actual application process, if the user, that is, the developer mentioned above, determines that the target server does not have printing authority, he can input the log adjustment instruction including at least the identification information of the target server and its log level adjustment information into the second service terminal, so that the second server terminal can obtain the log level adjustment instruction and send it to the monitoring terminal. Correspondingly, the monitoring terminal sends the log level adjustment command to the first server in response to the monitoring command sent by the first server, so that the first server adjusts the log level of the target server according to the log level adjustment information, thereby realizing When the client submits a log printing service request, start the log printing service. For the specific implementation process, please refer to the introduction below.

The aforementioned terminals may include mobile phones, computers, wearable devices, smart mobile devices, virtual reality devices, etc., or any combination thereof.

Fig. 1 is a schematic diagram of a method for log printing provided by an embodiment of the present disclosure. As shown in FIG. 1 , an embodiment of the present disclosure provides a log printing method applicable to the first server, which may include:

S11, the first server sends a monitoring instruction to the monitoring terminal.

Optionally, before the first server sends the monitoring instruction to the monitoring end, the method further includes: the first server saves and loads a configuration file corresponding to a default log level. In this way, before adjusting the log level, the corresponding log printing service can still be started according to the default log level, which is convenient for users to trace the source of the problem online.

Optionally, the monitoring terminal in this embodiment of the present disclosure may be a monitoring terminal associated with a Zookeeper server (distributed application coordination service). Therefore, when the first server sends a monitoring command to the monitoring terminal associated with the Zookeeper server, the first server registers the monitoring function with the Zookeeper server by default, so as to monitor the information of the target server node. Alternatively, the monitoring terminal may be a monitoring terminal associated with a Redis server (Remote Dictionary Server, remote dictionary service). Therefore, when the first server sends a monitoring instruction to the monitoring terminal associated with the Redis server, the first server subscribes to the information channel of the target server by default, so as to subscribe to the message queue of the target server. Through the above monitoring terminal, it is convenient to receive the log level adjustment information subsequently, so that the first server dynamically adjusts the log level of the target server according to the log level adjustment information, which is simple and easy to operate.

S12. Determine the target server that needs to adjust the log level according to the information returned by the monitoring terminal. The information returned by the monitoring terminal includes at least identification information of the target server and log level adjustment information of the target server.

Wherein, the target server may be a single server in the distributed system that needs to adjust the log level; or, the target server may be multiple servers in the distributed system that need to adjust the log level.

Optionally, the information returned by the monitoring terminal may only include the identification information of the target server and the log level adjustment information of the target server. In this way, the first client can directly determine the target server that needs to be adjusted to the log level, so as to facilitate the subsequent rapid adjustment of the log level . Alternatively, the information returned by the monitoring terminal may include the identification information of all servers in the distributed system and the log level adjustment information corresponding to each server. In this case, the log level adjustment information may include whether the log level of the server needs to be adjusted, and For the specific level information that the server needs to adjust, the first server can determine the target server according to the log level adjustment information corresponding to each server returned by the monitoring end.

S13. Adjust the log level of the target server according to the log level adjustment information.

Wherein, the log level adjustment information at least includes the target log level of the target server.

Optionally, the embodiments of the present disclosure may provide configuration files corresponding to various implementation parties obtaining log level adjustment information. The following example illustrates.

In one way, the first server can directly save the configuration files corresponding to various log levels locally. In this way, when the first server obtains the log level adjustment information, that is, when it obtains the target log level of the target server, it can directly call the target The configuration file corresponding to the log level. In this way, multiple calls to the configuration file can be realized, which also helps to reduce the amount of data returned by the monitoring terminal and improve the overall operating efficiency.

In another way, the monitoring end can save configuration files corresponding to various log levels, so that when returning information to the first server, the configuration files corresponding to the target log level can be returned to the first server together. Alternatively, the second client can save configuration files corresponding to multiple log levels, so that when the second client sends the log level adjustment instruction to the monitoring end, it can send the configuration files corresponding to the target log level to the monitoring end together, In order for the monitoring terminal to send the log level adjustment information and the configuration file corresponding to the target log level to the first server together when obtaining the monitoring command sent by the first server, for the first server to adjust the log level of the target server.

Optionally, after the first server obtains the configuration file corresponding to the target log level, the method further includes: writing the configuration file corresponding to the target log level into the memory of the target server node. In this way, the target server can update the log level without restarting, reducing the risk of restarting the server.

Wherein, the log level of the server may at least include five levels of FATAL (fatal), ERROR (error), WARN (warning), INFO (information), and DEBUG (debugging) arranged in descending order of priority. The priority from high to low corresponds to the printing permission from high to low. For example, if the log level of the current server node is DEBUG, the corresponding printing permission is to print logs higher than the log level and logs equal to the log level. , that is, the logs of FATAL, ERROR, WARN, INFO and DEBUG levels can be printed, that is, all logs can be printed.

As an example, the terminal associated with the client may be configured with an information entry module, and the user directly enters the print identification information into the client associated with the terminal through the information entry module. For example, the information input module can be embodied as a keyboard, and the user can manually input the print identification information through the keyboard for the client to collect; or, the information input module can be embodied as a voice collection module, and the user can input the print identification information by voice, and the client Carry out speech recognition and obtain printing identification information. All of the above methods can enable the user to enter the printing identification information conveniently and quickly, so that the client associated with the user can send the printing identification information to the first server.

Optionally, if the printing authority indicates that the printing identification information needs to be verified, the log printing service may be canceled if the verification of the printing identification information fails. The cancellation of the log printing service in the embodiment of the present disclosure may be canceling the log printing service when all the print identification information fails to be verified. Alternatively, the log printing service may be canceled when any of the print identification information fails to be verified. This can be set according to the actual production environment, and is not specifically limited in the embodiments of the present disclosure.

In the actual application process, take the printed identification information as the mobile phone number of online customer A as an example. After the project starts, if the mobile phone number of online customer A needs to be verified, the pre-stored mobile phone number of online customer A is obtained. Aa, and enter the mobile phone number AA of online customer A to match with the pre-stored mobile phone number. In this example, the verification of the mobile phone number of the online customer fails, and the log printing service can be canceled at this time; or, other printing identification information can be continued to be verified.
