Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, log waterfall frequently appears in the prior art, and the log waterfall can cause the waste of storage space, the scheduling problem of losing of effective log information, therefore, this application provides a log storage scheme, can prevent log waterfall problem, practices thrift the storage space of storage log, also can avoid losing of effective log information, ensures the comprehensiveness of system log, provides reliable foundation for trouble problem location.
Referring to fig. 1, an embodiment of the present application discloses a log storage method, including:
s101, acquiring a storage request of target log information.
Wherein the storage request is transmitted to the log system through an interface of the log system. The storage request comprises target log information needing to be stored at this time, identification information corresponding to the target log information and a preset time interval corresponding to the target log information. Each log in the log system corresponds to one piece of identification information (the number and the type of the logs to be recorded in the storage system are generally preset, so that the identification information can be set for each log) and a preset time interval, and the identification information and the preset time interval of each piece of log information are preset. The identification information of each log is different, but the preset time interval may be the same. Therefore, the preset time interval corresponding to the target log information is also the preset time interval of the identification information corresponding to the target log information. The preset time interval is a standard time interval for updating the log information set by the user based on the service requirement, and the standard time interval corresponds to the unique identification information. The storage request is generated at the storage system, and when a new piece of log information is generated in the storage system, a storage request is generated.
In a specific embodiment, before obtaining the storage request of the target log information, the method further includes: setting identification information and a preset time interval. Specifically, the identification information and the preset time interval can be manually set by a user on a human-computer interaction interface, or can be written in a script, and the setting is automatically completed by the script.
S102, extracting identification information and a preset time interval of target log information from the storage request.
S103, calculating the actual time interval between the previous log information and the target log information corresponding to the identification information.
Referring to fig. 2, fig. 2 is a detailed flowchart of step S103 in fig. 1. The specific implementation step of S103 in fig. 1 includes:
s201, determining a previous time stamp of previous log information and a target time stamp of target log information;
s202, calculating a difference value between the previous time timestamp and the target timestamp;
and S203, determining the difference value as an actual time interval.
In one embodiment, determining a previous timestamp of previous log information and a target timestamp of target log information comprises: inquiring the timestamp of the previous time; the target timestamp is extracted from the storage request.
The identification information corresponding to each log is fixed, but the log information corresponding to the identification information changes in real time. One identification information may correspond to a plurality of pieces of log information. In this embodiment, the target log information is current log information corresponding to the identification information. The previous time stamp of the previous log information may be regarded as the generation time stamp of the previous log information, and the target time stamp of the target log information may be regarded as the generation time stamp of the target log information. The generation time stamp of the log information can be seen as the time stamp of the transmission of the storage request to the logging system, since the logging of the log information is generally instantaneous.
S104, judging whether the actual time interval is greater than a preset time interval or not; if yes, executing S105; if not, go to step S106.
And S105, storing the target log information.
In one embodiment, storing the target log information includes: and storing the target log information to a power-down nonvolatile storage medium. If the actual time interval is larger than the preset time interval, the current log information is normal, and the target log information is stored in the power-down nonvolatile storage medium to realize log recording. Wherein the stored target log information comprises: log description information, log importance level, and log function category (i.e., which business module the log corresponds to).
And S106, filtering the target log information.
In one embodiment, filtering the target log information includes: and storing the target log information to a power-down volatile storage medium. If the actual time interval is not greater than the preset time interval, the log information corresponding to the identification information is generated too frequently and is not in accordance with the conventional service requirement, so that the current log information is abnormal, and the current log information is filtered.
In this embodiment, the filtering target log information is not to ignore the target log information and store the target log information, but to temporarily store the target log information in the power-down volatile storage medium, so that if the filtering is out of order, the target log information can be timely queried and stored in the log information under the condition that the storage system is not powered off.
In one embodiment, after calculating the actual time interval between the previous log information and the target log information corresponding to the identification information, the method further includes: judging whether a first state corresponding to the identification information recorded in the log resource list is consistent with a second state of the target log information or not; if so, updating the time interval corresponding to the identification information recorded in the log resource list to be the actual time interval. If not, the first state is updated to the second state, and the time interval corresponding to the identification information recorded in the log resource list is updated to the actual time interval.
The log resource list may correspond to each log one to one, or may be a total log resource list corresponding to all logs to be recorded. The log resource list records the latest log state (i.e. the first state) and the update time interval corresponding to each piece of information. The log state includes: normal state, abnormal state, etc.
Therefore, after the storage request of the target log information is obtained, the identification information and the preset time interval of the target log information are extracted from the storage request; then calculating the actual time interval between the previous log information and the target log information corresponding to the identification information; if the actual time interval is larger than the preset time interval, indicating that the current log information is normal, and storing the target log information; if the actual time interval is not larger than the preset time interval, the current log information is abnormal, and the target log information is filtered, so that the screening of the log information is realized. That is, all log information is not blindly stored, but some log information is stored after log information is filtered. Therefore, the embodiment can prevent the problem of log waterfall, save the storage space for storing the logs, avoid the loss of effective log information, ensure the comprehensiveness of the system logs and provide reliable basis for fault problem positioning.
According to the method provided by the embodiment, the filtering function can be added to the log system. The method provided by the embodiment is implemented at the interface of the log system, and if the log information meets the corresponding condition, the log information is allowed to be stored in the log system. Otherwise, it is filtered.
Specifically, unified management of the logs is realized in the log system, independent identification information is distributed to each log, and storage resources which are the same in size but independent from each other are distributed to each log. Wherein, the log filtering conditions are as follows: comparing the actual time interval of updating a certain log with the preset time interval set by a user, if the actual time interval is greater than the preset time interval, indicating that the current log information is normal, and storing the target log information; if the actual time interval is not larger than the preset time interval, the current log information is abnormal, and the target log information is filtered, so that the screening of the log information is realized. The filtered log information is recorded in the power-down volatile storage medium, and the storage resource of the power-down nonvolatile storage medium is not occupied.
Each log corresponds to a log resource list, and the log resource list comprises: identification information, update interval, and log status. When new log information needs to be recorded in the log system, firstly, the log resource list is traversed, the identification information of the log information to be stored currently is found, and the preset time interval and the actual time interval of the log information to be stored currently are further compared, wherein the actual time interval is the time interval between the log information to be stored currently and the previous log information of the identification information. If the actual time interval is larger than the preset time interval, storing the target log information; and if the actual time interval is not greater than the preset time interval, filtering the target log information.
Therefore, the embodiment can effectively prevent log waterfall, effectively filter invalid log information, prevent the same log from being repeatedly recorded in a log system, occupy precious log storage space, and prevent the invalid log from covering effective logs.
