It can be understood that the storage pressure of the blockchain can be reduced by using the off-chain address to store the log to be acquired instead of using the blockchain to store the log to be acquired. And the off-chain address is stored in the block chain, so that the off-chain address can be prevented from being tampered. Acquiring a log indicated by a chained external address; determining second characteristic value data uniquely corresponding to the acquired log; if the second characteristic value data and the first characteristic value data match, it is confirmed that the acquired log is available. Therefore, the acquired log is used only when the acquired log is accurate, and the truth and the effectiveness of the log are ensured. And the off-chain address and the first characteristic value data are both stored in the block chain, so that the off-chain address is kept secret, and the possibility that the log indicated by the off-chain address is tampered can be greatly reduced. Therefore, the method improves the safety and reliability of the log. The method also stores the log to be acquired in a non-blockchain storage space, so that the storage pressure of the log to be acquired on the blockchain can be greatly reduced while the safety of the log to be acquired is ensured by using the blockchain.

In one embodiment, the first characteristic value data is generated by processing the log to be acquired by adopting a characteristic value generation algorithm corresponding to the log to be acquired; the characteristic value data generated by the characteristic value generation algorithm aiming at the same log has uniqueness; determining that the acquired log uniquely corresponds to the second characteristic value data includes: acquiring a characteristic value generation algorithm which is stored in a block chain and corresponds to a log to be acquired; and processing the acquired log by using the acquired characteristic value generation algorithm to obtain second characteristic value data uniquely corresponding to the acquired log.

Specifically, the first characteristic value data is generated by processing the log to be acquired by using a characteristic value generation algorithm corresponding to the log to be acquired. The eigenvalue generation algorithm has uniqueness with respect to the eigenvalue data generated by the same log.

In one embodiment, the log to be obtained is a log generated by the target program; the method further comprises the following steps: if the acquired log is available, acquiring configuration information for the target program; the configuration information is stored in the block chain correspondingly with the out-of-chain address and the first characteristic value data; and tracing the acquired log by using the configuration information.

Specifically, the log to be acquired is a log generated by the target program. And if the acquired log is available, the terminal acquires the configuration information aiming at the target program. The configuration information, the out-of-chain address and the first characteristic value data are stored in the block chain correspondingly. The terminal can trace back the acquired log using the configuration information.

In one embodiment, the terminal may trace back the acquired log according to the existing problem, or trace back the acquired log according to the key information to be extracted, and so on.

In this embodiment, the configuration information in the block chain is acquired to trace back the acquired log, so that the configuration information is also effectively kept secret, and the reliability of processing the log is improved.

In one embodiment, the log to be obtained is a log data packet designated for obtaining; before acquiring an off-link address of a log to be acquired stored in a block chain and first characteristic value data uniquely corresponding to the log to be acquired, the method further comprises a log metadata chaining step; the log metadata chaining step comprises: packing the generated logs to generate log data packets under the condition that the generated logs meet the log fragmentation conditions; determining characteristic value data of a log data packet, and storing the log data packet in a non-block chain storage space to obtain an out-chain address of the log data packet; and correspondingly storing the characteristic value data of the log data packet and the chain external address in the block chain.

The metadata is data of data, and the log metadata is metadata of a log to be acquired, such as an out-of-link address, characteristic value data, and the like.

Specifically, the log to be acquired is a log data packet designated for acquisition. And under the condition that the generated logs meet the log fragmentation condition, the terminal packs the generated logs to generate log data packets. And the terminal determines the characteristic value data of the log data packet and stores the log data packet in the non-block chain storage space to obtain the out-chain address of the log data packet. And the terminal correspondingly stores the characteristic value data of the log data packet and the chain foreign address in the block chain.

In one embodiment, the terminal may store the time point or the fragment sequence number when the log is fragmented, so that after multiple logs are obtained, different logs may be combined according to the time point or the fragment sequence number when the logs are fragmented.

In this embodiment, under the condition that the log fragmentation condition is satisfied, the generated log is subjected to packing processing, and the related characteristic value data and the chain foreign address are correspondingly stored in the block chain. Therefore, ordered management of log storage can be realized, and arrangement and combination of multiple logs in the later period are facilitated.

In one embodiment, the log to be acquired is a log generated by the target program, and the target program runs the code logic and generates the log to be acquired at different time points by using corresponding configuration information of different versions; the method further comprises the following steps: acquiring configuration information of different versions used at different time points; correspondingly storing the characteristic value data of the log data packet and the chain external address into the block chain comprises the following steps: and correspondingly storing the configuration information of different versions, the characteristic value data of the log data packet and the chain foreign address in the block chain.

Specifically, the log to be acquired is a log generated by the target program, and the target program runs the code logic using the corresponding configuration information of different versions at different time points and generates the log to be acquired. The terminal acquires the configuration information of different versions used at different time points, and correspondingly stores the configuration information of different versions, the characteristic value data of the log data packet and the link foreign address in the block chain. It is understood that during the operation of the object program, the user may modify the configuration information so that the version of the configuration information is updated. Therefore, the configuration information and characteristic value data of different versions and the chain foreign address are correspondingly stored in the block chain, so that the log can be traced conveniently.

In one embodiment, the target program keeps the configuration information unchanged in the process of generating the log to be acquired, and the terminal correspondingly stores one version of the configuration information, the characteristic value data of the log data packet and the link foreign address in the block chain.

In one embodiment, the log to be acquired is an operation log of a big data platform, and the configuration information is configuration information of the big data platform.

In one embodiment, the terminal stores the configuration information in a blockchain by configuring an intelligent contract. Specifically, as shown in the schematic diagram of fig. 3, in the uplink preparation stage, the terminal determines that the configuration information that needs to be uplink may be configuration information of multiple versions or configuration information of one version. In the uplink stage, the terminal calls an interface for configuring the intelligent contract and stores the configuration information into the blocks of the block chain. The corresponding flow chart is as shown in fig. 4, and the terminal acquires the configuration information and invokes an interface provided by the configuration intelligent contract to trigger a related event so as to store the configuration information in the block chain. It is understood that the configuration information can be normalized and managed by linking the configuration information through the configuration intelligent contract.

In this embodiment, the terminal correspondingly stores the configuration information, the characteristic value data, and the link foreign address of different versions used at different time points in the block chain, so that the configuration information is effectively kept secret, and the log can be accurately traced, thereby ensuring the security and improving the accuracy.

In one embodiment, the first characteristic value data is generated by processing the log to be acquired by adopting a characteristic value generation algorithm corresponding to the log to be acquired; correspondingly storing the characteristic value data of the log data packet and the chain external address into the block chain comprises the following steps: calling a log intelligent contract interface processing characteristic value generation algorithm, characteristic value data and an out-link address of a log data packet, and generating a corresponding result; the results are stored into a blockchain.

Specifically, the first characteristic value data is generated by processing the log to be acquired by using a characteristic value generation algorithm corresponding to the log to be acquired. And the terminal calls a log intelligent contract interface to process a characteristic value generation algorithm, the characteristic value data and the out-link address of the log data packet and generates a corresponding result. The terminal stores the results into the blockchain.

In the present embodiment, the characteristic value generation algorithm, the characteristic value data of the log data packet, and the chain foreign address are stored by the log smart contract, so that the storage step of managing these data can be normalized, facilitating maintenance and management.

In one embodiment, the target program for generating the log to be acquired is a big data platform, the big data platform operation log collection system is used for collecting the operation log generated by the big data platform, and the processing end can use the method to complete the processing of the log. It is understood that the processing end may be a device of the big data platform operation log collection system, and may also be other devices. Specifically, as shown in fig. 5, the big data platform divides the account into different areas, such as an a area account, a B area account, and a C area account, where the account in each area may relate to multiple accounts, each account has a corresponding operation, an operation log is generated, and one operation log may be generated for one area or multiple areas. The big data platform oplog collection system collects these logs. The processing end divides the time into different stages, namely the log slicing condition is sliced according to the time. After the processing end acquires the logs from the big data platform operation log collection system, the logs generated in the stage 1 and the stage 2 can be packaged into one data packet, and the logs generated in the stage 3 and the stage 4 can be packaged into one data packet. And the processing end generates first characteristic value data corresponding to the data packet by using a characteristic value generation algorithm and stores the data packet into a non-block chain storage space. The processing side can also store the data packet to the non-blockchain storage space by calling a log intelligence contract. And the processing end stores the first characteristic value data of the data packet, the characteristic value generation algorithm and the chain external address into the block of the block chain through a log intelligent contract.

In one embodiment, oplogs of a large data platform need to be flushed for packed storage. Specifically, as shown in fig. 6, after the processing end obtains the big data platform operation log, the processing end performs data cleaning on the big data platform operation log, filters out useless data, and obtains an available big data platform operation log. The processing end judges whether a preset time slice is reached or whether the size of an available big data platform operation log reaches a preset threshold value, namely whether a preset log slicing condition is met. And when the log fragmentation condition is met, packing the available big data platform operation logs to generate a block data or a data packet, and acquiring corresponding characteristic value data, an out-link address and a characteristic value algorithm. It is to be understood that the feature value algorithm may be a hash algorithm. And the processing end calls a log intelligent contract to trigger a relevant event, and stores the characteristic value data, the out-link address and the characteristic value algorithm into the block chain. The processing end can also obtain the configuration information of different versions used at different time points, and the configuration information of different versions, the characteristic value data of the log data packet and the chain foreign address are correspondingly stored in the block chain by calling a log intelligent contract interface. In a traditional big data platform, an operation log only exists locally, and a historical operation log cannot guarantee whether the operation log is modified by others, so that whether data is real and effective or not cannot be confirmed during problem tracing. Compared with the traditional big data platform, the safety and the accuracy of the log can be ensured by the current big data platform by using the method.

In one embodiment, as shown in fig. 7, a flowchart illustrating how the obtaining end processes the log is shown. Specifically, the processing end acquires an off-chain address of a log to be acquired, which is stored in the block chain, a characteristic value generation algorithm, and first characteristic value data uniquely corresponding to the log to be acquired. The off-chain address is an address of a non-blockchain storage space used for storing the log to be acquired. And the processing end acquires the log indicated by the chain external address. And the processing end processes the acquired log by using the acquired characteristic value generation algorithm to obtain second characteristic value data uniquely corresponding to the acquired log. And the processing end compares the first characteristic value data with the second characteristic value data, and if the second characteristic value data is consistent with the first characteristic value data, the obtained log is confirmed to be available. And in the case that the acquired log is available, the processing end acquires configuration information corresponding to a chain foreign address on the block chain. The configuration information, the off-link address and the first characteristic value data are stored in the block chain correspondingly. The processing end can use the configuration information to perform problem tracing and the like on the acquired log.

It should be understood that, although the steps in the flowcharts in the embodiments of the present application are shown in sequence as indicated by the arrows, the steps are not necessarily executed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a part of the steps in the flow chart may include a plurality of steps or a plurality of stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the steps or the stages is not necessarily performed in sequence, but may be performed alternately or alternately with other steps or at least a part of the steps or the stages in other steps.
