In this embodiment, when the network connection is disconnected or the distributed cluster cannot work normally, the block chain log may be stored in the local storage area, and when the network connection is reestablished, the block chain log stored in the local storage area of the block chain point is sent to the distributed cluster, so that the distributed cluster centrally manages the block chain log; the block chain logs can be ensured not to be leaked again, and the block chain logs have strong network interference resistance; and the distributed cluster is adopted to carry out centralized management on the block chain logs, so that the disk resources of the block chain nodes can be saved.
The following are detailed below. The numbers in the following examples are not intended to limit the order of preference of the examples.
The block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The block chain, which is essentially a decentralized database, is a string of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, which is used for verifying the validity (anti-counterfeiting) of the information and generating a next block.
In this embodiment, a log management method is provided, as shown in fig. 1b, a specific process of the log management method may be as follows:
110. and generating a block chain log, wherein the block chain log comprises operation information generated when the block chain operates at the block chain link point.
In some embodiments, the blockchain nodes may generate blockchain logs based on a preset regular syntax, the blockchain logs including keywords and regular expressions matching the keywords. In some embodiments, the preset regular grammar may be a hook regular grammar, for example, matching may be performed given a keyword, such as a NUMBER keyword may match a NUMBER and an IP keyword may match an IP address of 127.0.0.1. It should be noted that, during the operation of the blockchain, the blockchain log is generated continuously over time, and the generated blockchain log may be encapsulated into one TCP packet at a fixed time interval and transmitted in the form of a TCP packet when the blockchain log is transmitted subsequently.
In some embodiments, the blockchain log further includes a timestamp, and the timestamp includes a preset time field, for example, the preset time field may be an @ timestamp field, and the blockchain log may be arranged according to the generated time sequence, not out of order, and according to the time zone conversion field.
In some embodiments, a switch function that initiates the log management method may be configured in a configuration file of block nodes, and the switch function may be triggered when a block node is initiated, or when a block chain is initiated, or manually by a user, etc. After the switch function is triggered, the log management method described in steps 110-140 of this embodiment is performed.
In some embodiments, the network addresses of the nodes in the distributed cluster, including information such as IP and port of the nodes, may be configured in a configuration file of the blockchain nodes. In some embodiments, after the blockchain node is started, or before the blockchain is generated, or after the network connection with the target node is disconnected, the blockchain node may acquire the network address of the target node, wherein the target node is any node in the distributed cluster, and may be a master node, a data node, or a client node. The blockchain node establishes a network connection between the blockchain node and the target node based on the network address of the target node, where the network connection may be a long connection or a short connection, and for example, the blockchain node may create a new thread using Socket to monitor a port of the target node. When the network connection between the block chain link point and the target node is successfully established, sending a block chain log to the target node; for example, the TCP protocol may be used to implement reliable transmission of the blockchain log through mechanisms such as checksum, sequence number, acknowledgement, retransmission control, connection management, and window control. It should be noted that there are multiple block nodes, so that a network connection pool can be established between the block nodes and the distributed cluster. Therefore, all the blockchain nodes support the distributed cluster configuration, and the condition that the log management function is unavailable when one node in the distributed cluster cannot work normally can be prevented.
In some embodiments, when the network connection between the block link node and the target node fails to be established, determining a next node, where the next node is any node in the distributed cluster except the target node; then obtaining the network address of the next node; the block link point establishes a network connection with the next node based on the network address of the next node. And if the network connection between the block link node and the next node is failed to be established, continuing to select the next node from the distributed cluster until the network connection with any node in the distributed cluster is successfully established, and starting the log management method successfully. And if the network connection between the block link node and all the nodes in the distributed cluster is failed to be established, the log management method fails to be started. In some embodiments, if the log management method fails to be started, the local storage blockchain log may be sent to the distributed cluster centralized management when the network connection between the blockchain node and the nodes in the distributed cluster is successfully established. In some embodiments, if the log management method fails to start, the block link point may display a prompt message to prompt the user that the log management method fails to start, so that the user can locate the problem and deal with the problem in time.
120. And when the network connection disconnection between the block chain link point and the target node is detected, the block chain log is stored in the local storage area, and the target node is any node in the distributed cluster.
In some embodiments, when a block link point is detected to be disconnected from the network of target nodes, the block chain log may be stored in the disk of the block link point.
In some embodiments, the method for detecting disconnection of a network connection is not limited, for example, the block nodes may send a detection request to the target node at preset time intervals, where the detection request is used to detect whether the network connection between the block nodes and the target node is disconnected, which may also be referred to as activation detection; the value of the preset time interval can be set according to practical application in a self-defined manner, for example, the value can be less than or equal to the fixed interval time of the TCP data packet by encapsulating the block chain log, so that the data packet is not lost when the network connection is disconnected. When the preset time length of the block chain link point does not receive response information aiming at the detection request from the target node, the disconnection of the network connection of the block chain link point and the target node is detected, and the preset time length can be set in a user-defined mode according to the actual application condition; the reason why the target node cannot respond to the request of the block link node may be caused by network jitter, or may be caused by the target node not working properly, for example, the target node crashes.
In some embodiments, when a block link point is detected to disconnect from the network of target nodes, the block link point may also determine the number of disconnections of the block link point from the network of target nodes; when the disconnection times are larger than the time threshold value, marking the target node as an unavailable node instead of considering disconnection caused by network jitter; and then the block chain node sends a disconnection request to the unavailable node so as to disconnect the network connection between the block chain link node and the unavailable node, stop sending the block chain log to the unavailable node and further locally store the block chain log. After being marked as an unavailable node, other blockchain nodes of the blockchain system do not establish network connection with the unavailable node any more. When the disconnection number is greater than the number threshold, the block chain log is stored locally, and then step 130 is performed.
130. And establishing a file index of the block chain log.
The file index can enable the locally stored block chain logs to have a sequence, so that the block chain logs can be read according to the file index in the following process, repeated reading can be avoided, and block chain logs can be prevented from being repeated.
140. When the network connection reestablishment of the block chain link point and the target node is detected, the block chain log is obtained from the local part based on the file index and is sent to the target node, so that the distributed cluster can conveniently manage the block chain log in a centralized mode.
Accordingly, the target node receives the blockchain log so that the distributed cluster can centrally manage the blockchain log.
In some embodiments, when it is detected that the network connection between the blockchain node and the target node is reestablished, it may be determined whether there is a blockchain log that is not sent to the distributed cluster locally, for example, through a file index. And when the blockchain log exists locally, acquiring the blockchain log from the local based on the file index, and sending the blockchain log to the target node.
In some embodiments, after the blockchain log is obtained from the local based on the file index and sent to the target node, the blockchain link point may further update the file index; the blockchain log is deleted locally, e.g., the blockchain log that has been sent to the target node is deleted locally.
In some embodiments, the target node may further control the display of the blockchain logs on a graphical user interface of the visualization device, so that a user may search, monitor, and analyze the blockchain logs in the distributed cluster through the graphical user interface, and may further aggregate a plurality of conditional search blockchain logs. For example, the blockchain logs are displayed on a graphical user interface of the visualization device through Kibana, and the blockchain logs in the distributed cluster can be searched, monitored and analyzed in an aggregation manner through a Web management interface of Kibana. And the block chain logs generated by each block chain node at each time can be visually seen. Therefore, the efficiency of positioning problems after the operation of the block chain is made mistakes is greatly improved, abnormal logs can be monitored and an alarm can be given, various problems in the block chain system can be discovered in time, and the efficiency of positioning problems after the operation of the block chain is made mistakes is improved.
As can be seen from the above, the block chain link point in this embodiment may send, when the network connection is disconnected or the distributed cluster cannot work normally, the block chain log stored locally to the distributed cluster when the network connection is reestablished, so that the distributed cluster centrally manages the block chain log; the block chain logs can be ensured not to be leaked again, and the block chain logs have strong network interference resistance; and the distributed cluster is adopted to carry out centralized management on the block chain logs, so that the disk resources of the block chain nodes can be saved. The block chain logs are visualized through visualization equipment, so that the log condition of each block chain link point at each time can be visually seen; and a plurality of condition searches can be aggregated, so that the efficiency of positioning problems after the operation of the block chain system is wrong is greatly improved, abnormal block chain logs can be monitored and an alarm can be given, and the problems can be found in time.
The log management scheme provided by the invention can be applied to various log management scenes. For example, taking the management of the blockchain log as an example, the log management scheme of the invention will be described in detail.
As shown in fig. 2, a specific flow of the log management method is as follows:
201. after the block link point is started, the block link point determines whether to start the log management method.
The log management method may be started by automatically triggering a switch function that starts the log management method, or may be started by manually triggering by a user.
202. And if the log management method is not started, storing the block chain log in the local block chain link point, and establishing a file index of the block chain log.
203. And if the log management method is started, establishing network connection between the block link nodes and the target nodes in the distributed cluster.
204. And if the network connection between the block chain nodes and the target nodes in the distributed cluster is successfully established, the log management method is successfully started, and the block chain nodes send the block chain logs to the distributed cluster in real time. If the network connection between the block chain link point and the nodes in the distributed cluster is failed to be established, the log management method fails to start, the step 202 is returned to be executed, and the block chain log is stored in the block chain link point locally, and the file index of the block chain log is established.
205. And the block chain node sends a detection request to the target node at a preset time interval, wherein the detection request is used for detecting whether the network connection between the block chain link node and the target node is disconnected.
206. When the disconnection of the network connection of the block link point and the target node is detected, the block link point may further determine whether the disconnection number of the network connection of the block link point and the target node is greater than a number threshold. And when the disconnection times are smaller than the time threshold value, returning to execute the step 202, and establishing a file index of the block chain log in the local storage area. And when the network connection with the target node is not disconnected, returning to the step 204.
207. When the disconnection times are larger than the time threshold value, marking the target node as an unavailable node; the blockchain node stops sending blockchain logs to unavailable nodes. When the number of disconnections is not greater than the number threshold, step 208 is performed.
208. When the network connection reestablishment of the block chain link point and the target node is detected, whether a block chain log which is not sent to the distributed cluster exists locally or not is judged.
209. And if the local block chain logs which are not sent to the distributed cluster exist, obtaining the block chain logs from the local based on the file index, and sending the block chain logs to the target node so that the distributed cluster can manage the block chain logs in a centralized manner. If the block chain log which is not sent to the distributed cluster does not exist locally, the step 204 is returned to be executed, and the block chain log is sent to the distributed cluster in real time.
210. The block chain link points can also update the file index; the blockchain logs that have been sent to the target node are deleted locally.
As can be seen from the above, when the network connection is disconnected or the distributed cluster cannot work normally, the block chain logs in the local storage area can be sent to the distributed cluster when the network connection is reestablished, so that the distributed cluster can manage the block chain logs in a centralized manner; the block chain logs are ensured not to be missed, and the block chain logs have strong network interference resistance; and the distributed cluster is adopted to carry out centralized management on the block chain logs, so that the disk resources of the block chain nodes can be saved.
In order to better implement the above method, the present invention further provides a log management device, and in this embodiment, the method of the present invention will be described in detail by taking an example in which the log management device is specifically integrated in a blockchain node.
