There may be master nodes, data nodes, client nodes, etc. in a distributed cluster. Information connection can exist between each node in the distributed cluster, and information transmission can be performed between the nodes through the information connection. In some embodiments, the distributed cluster may be an elastomer search-piggybacked cluster (ES cluster).
The visualization device may be a terminal or server independent of the blockchain system and the distributed cluster, or may be any blockchain node in the blockchain system or any node in the distributed cluster. The visualization device may search, analyze, and visualize blockchain logs stored in the distributed clusters based on the graphical interface. In some embodiments, the visualization device is a Kibana-mounted device.
In some embodiments, the blockchain node may generate a blockchain log that includes operational information generated when the blockchain is operating at the blockchain node; when the network connection disconnection between the blockchain node and the target node is detected, locally storing a blockchain log, wherein the target node is any node in the distributed cluster; establishing a file index of a block chain log; when the network connection between the blockchain node and the target node is detected to be reestablished, the blockchain log is obtained locally based on the file index and is sent to the target node, so that the distributed cluster can manage the blockchain log in a centralized mode.
In this embodiment, when the network connection is disconnected or the distributed cluster cannot work normally, the blockchain log is stored locally, and when the network connection is reestablished, the blockchain log stored locally at the blockchain node is sent to the distributed cluster, so that the distributed cluster centrally manages the blockchain log; the blockchain log can be ensured not to be heavy and leak, and the blockchain log has stronger network interference resistance; and the distributed clusters are adopted to perform centralized management on the blockchain logs, so that disk resources of the blockchain nodes can be saved.
The following will describe in detail. The numbers of the following examples are not intended to limit the preferred order of the examples.
Blockchains are novel application modes of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and the like. The blockchain is essentially a decentralised database, and is a series of data blocks which are generated by association by using a cryptography method, and each data block contains information of a batch of network transactions and 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, and a specific flow of the log management method may be as follows:
110. a blockchain log is generated, the blockchain log including operation information generated when the blockchain is operated at a blockchain node.
In some embodiments, the blockchain node may generate a blockchain log based on a preset regular grammar, the blockchain log 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 given keywords, e.g., NUMBER keywords may match NUMBERs, IP keywords may match IP addresses of 127.0.0.1. It should be noted that during the operation of the blockchain, the blockchain log is continuously generated over time, and the generated blockchain log may be encapsulated into a TCP packet at fixed time intervals, and transmitted in the form of the TCP packet when the blockchain log is transmitted later.
In some embodiments, the blockchain log also includes a timestamp that includes a preset time field, e.g., the preset time field may be @ timestamp field, which may allow the blockchain log to be arranged in the time order generated, out of order, and according to the time zone conversion field.
In some embodiments, a switching function that initiates the log management method may be configured in the configuration file of the blockchain link point, which may be triggered at startup of the blockchain node, or at startup of the blockchain, or manually by a user, or the like. 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 address of the node in the distributed cluster may be configured in a configuration file of the block link point, where the network address includes information such as the IP and port of the node. In some embodiments, the blockchain node may obtain the network address of the target node after the blockchain node is started, or before the blockchain is generated, or after a network connection with the target node is broken, 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, wherein the network connection can be a long connection or a short connection, for example, the blockchain node can use Socket to create a new thread to monitor a port of the target node. When the network connection between the block chain node and the target node is successfully established, a block chain log is sent to the target node; for example, the reliable transmission of blockchain logs may be implemented using the TCP protocol through mechanisms such as checksum, sequence number, acknowledgement, retransmission control, connection management, window control, and the like. It should be noted that there are multiple blockchain nodes, so that the blockchain nodes and the distributed clusters can establish a network connection pool. Therefore, all the blockchain nodes support distributed cluster configuration, and the situation that a 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 establishment of the blockchain node and the target node fails, determining a next node, wherein the next node is any node except the target node in the distributed cluster; then obtaining the network address of the next node; the blockchain node establishes a network connection between the blockchain node and the next node based on the network address of the next node. If the network connection between the block chain node and the next node is failed to be established, the next node is continuously selected from the distributed cluster until the network connection between the block chain node and any node in the distributed cluster is established successfully, and the log management method is started successfully. If the network connection between the block chain node and all nodes in the distributed cluster fails to be established, the log management method is started to fail. In some embodiments, if the log management method fails to start, the blockchain log may be stored locally at the blockchain node, and the locally stored blockchain log may be sent to the distributed cluster for centralized management until the network connection between the blockchain node and the nodes in the distributed cluster is established successfully. In some embodiments, if the log management method fails to start, the blockchain node may display a prompt message to prompt the user that the log management method fails to start, so that the user locates the problem and processes it in time.
120. When the network connection disconnection between the blockchain node and the target node is detected, the blockchain log is stored locally, and the target node is any node in the distributed cluster.
In some embodiments, when a network disconnection of a blockchain node from a target node is detected, a blockchain log may be stored in a disk of the blockchain node.
In some embodiments, the method for detecting the disconnection of the network is not limited, for example, the blockchain node may send a detection request to the target node at a preset time interval, where the detection request is used to detect whether the network connection between the blockchain node and the target node is disconnected, which may also be referred to as a probe activity; the value of the preset time interval can be set in a self-defined manner according to practical application, for example, the fixed interval time of the encapsulation blockchain log as the TCP data packet can be smaller than or equal to the fixed interval time of the encapsulation blockchain log, so that the data packet is not lost when the network connection is disconnected. When the preset duration of the blockchain node does not receive response information from the target node for the detection request, the network connection disconnection between the blockchain node and the target node is detected, and the preset duration can be set in a self-defined mode according to the actual application condition; the reason why the target node cannot respond to the request of the blockchain node may be caused by network jitter, or may be caused by that the target node cannot work normally, for example, the target node crashes.
In some embodiments, when a network disconnection of the blockchain node from the target node is detected, the blockchain node may also determine a number of disconnection times of the network disconnection of the blockchain node from the target node; when the disconnection times are greater than the times threshold, marking the target node as an unavailable node, and not considering the disconnection caused by network jitter; and the blockchain node sends a disconnection request to the unavailable node so as to disconnect the network connection of the blockchain node and the unavailable node, stop sending the blockchain log to the unavailable node and further store the blockchain log locally. After being marked as an unavailable node, other blockchain nodes of the blockchain system no longer establish network connections with the unavailable node. When the number of breaks is greater than the number threshold, then the blockchain log is stored locally and then step 130 is performed.
130. And establishing a file index of the blockchain log.
The file index can enable the locally stored blockchain logs to have an order, so that the blockchain logs can be read according to the file index later, the situation that the blockchain logs are read repeatedly can be avoided, and the blockchain logs are prevented from being read repeatedly can be ensured.
140. When the network connection between the blockchain node and the target node is detected to be reestablished, the blockchain log is obtained locally based on the file index and is sent to the target node, so that the distributed cluster can manage the blockchain log in a centralized mode.
Accordingly, the target node receives the blockchain log for centralized management of the blockchain log by the distributed cluster.
In some embodiments, when a network connection of a blockchain node to a target node is detected to be reestablished, it may be determined whether there is a blockchain log locally that is not sent to the distributed cluster, e.g., by a file index. When the blockchain log exists locally, the blockchain log is acquired from the local based on the file index and is sent to the target node.
In some embodiments, the blockchain node may also update the file index after locally obtaining the blockchain log based on the file index and sending to the target node; 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 also control the blockchain logs to be displayed on a graphical user interface of the visualization device so that a user may find, monitor, analyze blockchain logs in the distributed cluster through the graphical user interface, and may aggregate multiple conditional search blockchain logs. The blockchain logs are displayed on a graphical user interface of the visualization device, for example, through Kibana, and the blockchain logs in the distributed clusters can be searched, monitored and analyzed through the Web management interface aggregate of Kibana. And the blockchain log generated by each blockchain node at each time can be intuitively seen. Therefore, the efficiency of positioning the block chain after the running error is greatly improved, the abnormal log can be monitored and the alarm can be given, various problems in the block chain system can be found in time, and the efficiency of positioning the block chain system after the running error is improved.
As can be seen from the above, when the network connection is disconnected or the distributed cluster cannot work normally, the blockchain node in this embodiment stores the blockchain log locally, and when the network connection is reestablished, the blockchain log stored locally is sent to the distributed cluster, so that the distributed cluster centrally manages the blockchain log; the blockchain log can be ensured not to be heavy and leak, and the blockchain log has stronger network interference resistance; and the distributed clusters are adopted to perform centralized management on the blockchain logs, so that disk resources of the blockchain nodes can be saved. The block chain logs are visualized through the visualization equipment, so that the log situation of each block chain node at each time can be intuitively seen; the method can also aggregate a plurality of condition searches, greatly improve the efficiency of locating the problem after the operation error of the block chain system, monitor the abnormal block chain log and alarm, and discover the problem in time.
The log management scheme provided by the application can be applied to management scenes of various logs. For example, the management of blockchain journals is taken as an example, and the journal management scheme of the present application will be described in detail.
As shown in fig. 2, a specific flow of the log management method is as follows:
201. after the blockchain node is started, the blockchain node 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 manual triggering by a user.
202. If the log management method is not started, the blockchain log is stored locally at the blockchain node, and a file index of the blockchain log is established.
203. If the log management method is started, network connection between the blockchain node and the target node in the distributed cluster is established.
204. If the network connection between the block chain node and the target node in the distributed cluster is established successfully, the log management method is started successfully, and the block chain link point sends the block chain log to the distributed cluster in real time. If the network connection between the blockchain node and the nodes in the distributed cluster fails to be established, the log management method is started to fail, and returns to execute step 202 to store the blockchain log locally in the blockchain node, and establish the file index of the blockchain log.
205. The blockchain node sends a detection request to the target node at preset time intervals, wherein the detection request is used for detecting whether the network connection between the blockchain node and the target node is disconnected.
206. When detecting that the network connection of the blockchain node to the target node is broken, the blockchain node may also determine whether a number of times the network connection of the blockchain node to the target node is broken is greater than a number threshold. When the number of disconnection times is smaller than the number threshold, the step 202 is further executed, the blockchain log is stored locally, and the file index of the blockchain log is established. When it is detected that the network connection with the target node is not broken, the execution returns to step 204.
207. When the disconnection times are greater than the times threshold, marking the target node as an unavailable node; the blockchain node stops sending blockchain logs to unavailable nodes. When the number of disconnection times is not greater than the number threshold, step 208 is performed.
208. When the network connection between the blockchain node and the target node is detected to be reestablished, judging whether the blockchain log which is not sent to the distributed cluster exists locally or not.
209. If the blockchain log which is not sent to the distributed cluster exists locally, the blockchain log is obtained locally based on the file index and is sent to the target node, so that the distributed cluster can manage the blockchain log in a centralized mode. If there is no blockchain log locally that is not sent to the distributed cluster, then step 204 is returned to send the blockchain log to the distributed cluster in real time.
210. The blockchain node may also update the file index; the blockchain log that has been sent to the target node is deleted locally.
According to the above, when the network connection is disconnected or the distributed cluster cannot work normally, the blockchain log is stored locally, and when the network connection is reestablished, the blockchain log stored locally is sent to the distributed cluster, so that the distributed cluster can manage the blockchain log in a centralized manner; the blockchain log can be ensured not to be heavy and leak, and the blockchain log has stronger network interference resistance; and the distributed clusters are adopted to perform centralized management on the blockchain logs, so that disk resources of the blockchain nodes can be saved.
In order to better implement the above method, the present application also provides a log management device, and in this embodiment, the method of the present application will be described in detail by taking the specific integration of the log management device in a blockchain node as an example.
