Detailed Description
The invention is further described below with reference to examples.
As shown in FIG. 1, the log-based VPP configuration recovery system comprises a log agent module, a configuration recovery module and a configuration recovery state checking module, wherein the log agent module, the configuration recovery module and the configuration recovery state checking module are deployed in a server for deploying the VPP, the log agent module, the configuration recovery module and the configuration recovery state checking module are implanted in the VPP, the log agent module is in communication connection with the configuration recovery module, and the configuration recovery module is in communication connection with the configuration recovery state checking module. The log agent module is used for monitoring execution of each configuration type CL I command in the VPP, generating a CL I log file for recording execution time and execution result of each configuration type CL I command executed in the VPP and the configuration type CL I command according to monitoring of each configuration type CL I command, the log agent module is used as a component of the VPP and operates, the configuration recovery module is used for recovering configuration for the VPP according to the CL I log file, and the configuration recovery state checking module is used for identifying the configuration recovery state of the VPP and checking the configuration recovery state.
As shown in fig. 2, when the configuration recovery system for VPP based on log is used to recover the configuration of VPP, the specific operation steps are as follows:
s1) when the VPP is configured before the VPP is operated for the first time, monitoring the execution of each configuration type CL I command in the VPP by using a log agent module, generating a CL I log record according to the configuration type CL I command, the execution time and the execution result of the configuration type CL I command, and recording the CL I log record in a CL I log file;
s2) when the VPP is restarted, the configuration recovery module is utilized to read the CL I log record from the CL I log file in the step S1) and recover the VPP configuration according to the CL I log record.
In VPP, CL I commands can be divided into two main categories: (1) a configuration class CL I command, which is used to configure the VPP, such as setting an interface state, setting an interface I P address, etc.; (2) non-configuration class CLI commands, such as CL I commands to view the configuration and status of the VPP, do not configure the VPP, such as view interface status, view interface I P address, etc.
In the invention, on a server for deploying the VPP, the name of the CLI log file defaults to c l i.l og and is stored under the/var/log/VPP directory by default, namely, the absolute path of the CLI log file is/var/log/VPP/c l i.l og.
In the CLI log record, the execution result of the configuration class CLI command is success (expressed by success) or failure (expressed by fai l ure), and the execution time of the configuration class CLI command is expressed by the time when the execution of the configuration class CLI command ends, which is referred to as the time of the CLI log record (hereinafter referred to as log time) in the present invention. The log time is accurate to milliseconds, including years, months, days, hours, minutes, seconds, milliseconds, as in "2022-12-06:08:08:123", with the log time in the example representing 2022, 12, 6, 8 minutes, 8 seconds, 123 milliseconds.
In the CLI log file, each CLI log record contains log time, execution result, and CL I command. The format of the CLI log record is 'log time|execution result|CLI command', which are log time, execution result and CLI command in sequence from left to right, are separated by vertical lines|and are provided with a space in front of and behind the vertical lines. The CLI log file shown in table 1 contains 3 CL log records.
Table 1CLI log file
And the log agent module adds the generated CL I log record to the tail of the CL I log file according to the time sequence. That is, in the CL I log file, the CL I log with the earlier log time is recorded before, and the CLI log with the later log time is recorded after.
The configuration recovery module reads all the CLI log records from the CLI log file, and the CLI log records are arranged in the CLI log file according to the time sequence, namely the CLI log record with the earlier log time is recorded before the CLI log record with the later log time is recorded after the CLI log record with the later log time, and the CL I log records read by the configuration recovery module are arranged according to the time sequence.
And then, the configuration recovery module processes each CLI log record from front to back in sequence one by one according to the time sequence of the CLI log records, and recovers the configuration of the VPP.
The configuration recovery module performs the following processing on each CLI log record in the CLI log file when recovering configuration for the VPP according to the CL log file: and when the execution result is success, the configuration recovery module actively executes the CLI log record to process according to the principle, and after the processing of all the CLI log records is completed, the configuration of the VPP is recovered.
In the invention, the configuration recovery state checking module checks the configuration recovery state of the VPP, in particular checks the value of the configuration recovery label in the VPP, through a non-configuration CLI command, so as to confirm whether the VPP has completed recovery operations of all configurations.
There are two values for the configuration recovery tag: (1) SUCCESS, which indicates that the configuration restoration module has completed processing and VPP has completed restoration operations for all configurations; (2) RECOVERING, which indicates that the configuration restoration module has not completed processing and that the VPP is performing configuration restoration operations.
If and only if the value of the configuration recovery tag is SUCCESS, i.e. the VPP has completed all configured recovery operations, and the configuration is set for the VPP again by the configuration class CLI command, the log proxy module will generate a new CLI log record, and record the new CLI log record into the CLI log file in time sequence, and cannot cover the original CLI log record. When the configuration recovery module is executing the configuration recovery operation, that is, the value of the configuration recovery label is RECOVERING, the configuration cannot be set for the VPP through the new configuration class CLI command, and the log agent module does not generate any new CL I log record.
After a start-up (or restart), the VPP is first initialized according to the configuration items in the configuration file. After the initialization is completed, the value of the configuration recovery tag is set to RECOVERING.
The configuration restoration module then begins processing to restore all configurations of the VPP. After the configuration recovery module completes processing, indicating that the VPP has completed recovery operations for all configurations, the value of the configuration recovery tag is set to SUCCESS.
After the VPP completes the recovery operations for all configurations, the log agent module begins processing, continuously monitors each CL I command executed in the VPP, and generates a CL I log record for use in configuration recovery after the next restart.
Based on the above log-based VPP configuration restoration method, correspondingly, there is also provided a computer readable storage medium storing a computer program, which when executed by a processor, implements the steps of: monitoring the execution of each configuration type CL I command in the VPP by using a log proxy module implanted in the VPP, generating a CL I log record according to the configuration type CL I command, the execution time and the execution result of the configuration type CL I command, recording the CL I log record in a CL I log file, and when the VPP is restarted, reading the CL I log record from the CL I log file by using a configuration recovery module implanted in the VPP and recovering the VPP according to the CL I log record.
As shown in fig. 3, in this embodiment, there is further provided a computer device, which includes a readable storage medium, a processor, and a computer program stored on the readable storage medium and executable on the processor, wherein the readable storage medium and the processor are both disposed on a bus, and the processor implements the following steps when executing the computer program: monitoring the execution of each configuration type CL I command in the VPP by using a log proxy module implanted in the VPP, generating a CL I log record according to the configuration type CL I command, the execution time and the execution result of the configuration type CL I command, recording the CL I log record in a CL I log file, and when the VPP is restarted, reading the CL I log record from the CL I log file by using a configuration recovery module implanted in the VPP and recovering the VPP according to the CL I log record.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments.
