A method for remotely controlling a T-BOX system log is applied to the T-BOX, the T-BOX is used as a client and is provided with a network communication module and a log information processing module, and the method comprises the following steps:
the output level of the T-BOX system LOG information is mainly divided into four levels of LOG _ ERROR, LOG _ WARNING, LOG _ TRACE and LOG _ DEBUG, and the TBOX system only outputs the LOG _ ERROR level information by default.
The T-BOX system and the cloud server are based on an MQTT communication protocol, and the MQTT cloud server issues a command for controlling the T-BOX system to output log grade information.
And after receiving a control log command sent by the cloud server, a network communication module in the T-BOX system sends the control log command to a log processing module through interprocess communication.
And after receiving the control command of the log information output level, a log processing module in the T-BOX system outputs corresponding log information according to the command.
After a LOG processing module in the T-BOX system receives a LOG information storage path and a size control command, the LOG information is stored to a set path according to the command, for example, the LOG information is set within ten minutes, and the total memory of the output LOG _ ERROR LOG exceeds 20M, so that the T-BOX system is proved to have great problems, and the T-BOX system gives an alarm at the moment, so that a person knows that the T-BOX system has problems at a remote cloud server. At this point, another copy of LOG _ ERROR LOG for the first ten minutes is saved in the child exception folder. The problem is conveniently treated in a centralized way. When a single parent folder occupies a certain memory, all files in the parent folder are compressed into log compression packets and stored in the parent folder, the child abnormal folders and the system logs in the parent folder are deleted, and only the log compression packets are left.
When the memory of the storage unit of the T-BOX system is full, for example, the real-time file occupies more than seventy percent of the total storage unit, the file is compressed and uploaded to the cloud server, the cloud server is enabled to alarm and prompt personnel, and when the file is successfully uploaded to the cloud server, the system log, the sub-abnormal file and the daily-to-compressed packet in the storage unit of the T-BOX system are deleted.
Specifically, as shown in fig. 4, the method further includes setting a predetermined time, compressing and uploading all the parent folders of the T-BOX system storage unit to the cloud server every other predetermined time, and deleting all the system logs, the child exception folders, and the log compression packages of the parent folders in the T-BOX system storage unit. The logs are uploaded regularly, personnel can check the logs regularly conveniently, the safety of the logs is guaranteed, and some logs possibly existing in a small number in program running can be uploaded irregularly, so that key messages can be missed to cause great threat.
Specifically, as shown in fig. 3, the preset identification method includes identifying in real time by using a stat function of the Linux system and outputting each memory occupation value of the multiple levels of the system logs. The prior art of the stat function can identify the memory occupation value of the system log, and a specific implementation mode is provided.
Specifically, as shown in fig. 2, the set control command includes that the T-BOX system and the server are based on an MQTT communication protocol and issue a JSON-format data protocol command, where the JSON-format data protocol command includes { "TBOXSN": "XXX", "CtlType": "LOG grade", "TypeNum": X "," TYPE1": LOG _ ERROR" ·, where "TBOXSN": XXX "represents a product serial number of the T-BOX," CtlType ": and" LOG grade "represents a control LOG level output," TypeNum ": X" represents a number of control LOG level outputs, and an X range is 1 to 4, "TYPE1": LOG _ ERROR "represents a TYPE of the level. A specific control command is set, and this embodiment is preferred here.
Specifically, as shown in fig. 2, the multiple levels of system LOGs further include a LOG _ WARNING LOG, a LOG _ TRACE LOG, and a LOG _ DEBUG LOG. Generally, the method is divided into four types, so that people can more accurately search the real-time records.
Specifically, as shown in fig. 2, when the T-BOX system does not receive the set control command, all system LOGs are output according to the system LOG of the same level, and all system LOGs are stored in the same parent folder, where the system LOG of the same level is a LOG _ ERROR LOG. When the remote control is not received, all log information is output according to the same level, and then the log information is classified according to the above, so that the log can be automatically managed conveniently. New embodiments are provided.
