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 invention.
The terms "comprising" and "having," and any variations thereof, as referred to in embodiments of the present invention, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
With the development of internet technology, the system service architecture is also rapidly developing and changing. In consideration of poor loadability and disaster tolerance of a stand-alone system, a distributed system is usually adopted in the current system design, i.e., a multi-machine deployment mode is used for jointly supporting the same service, such as common large data component Hadoop, Hbase, Elasticsearch and other services. However, the multi-machine deployment mode has the problem of complex operation and maintenance, a common means for service operation and maintenance is to check logs, the check logs generally need to be logged in corresponding machine nodes for checking, and the efficiency is poor; at present, the logs are collected and displayed mainly in the following ways:
1. the log file is copied to the log center at regular time by using a system command combination of Secure Copy (SCP for short) + script and the like, and the mode is more original and has a plurality of defects: the efficiency is low, real-time log uploading cannot be realized, and a log transmission fault-tolerant mechanism is not provided.
2. The combination of various open source software such as ELK (elastic serach + Logstash + Kibana), flash + Kafka + elastic search + Kibana is used to realize the open source big data log collection mode, the advantage is that the collected logs can be displayed in real time, and the fault-tolerant mechanism is introduced into the logs, so that the defects that the whole process depends on more open source components and the deployment and maintenance costs are high are overcome.
3. The method has the disadvantages that the service of all service nodes shares one message queue, the log collection of all service nodes is influenced by the abnormal or blocked message queue network, and the fault-tolerant mechanism of log introduction is poor.
Therefore, a network client can display logs of service deployment services of different machine service nodes in real time, log contents can be refreshed manually or automatically, for a distributed system, the logs are collected to a center, and a log display server at the front end is necessary to check each service real-time log. Based on this, the embodiment of the present invention provides a method and an apparatus for presenting and aggregating logs of service nodes in a distributed system, and the technique can be applied to various distributed systems. To facilitate understanding of the embodiment, a detailed description will be given to a data processing method disclosed in the embodiment of the present invention.
The embodiment of the invention provides a method for displaying logs of service nodes in a distributed system, wherein the distributed system comprises a plurality of service nodes, at least one service program runs in each service node, the method is applied to a log display server, and the log display server is respectively in communication connection with the plurality of service nodes in the distributed system.
Referring to fig. 1, a distributed system includes a plurality of service nodes 102, where each service node 102 runs at least one service program, and a log display server 101 is respectively connected to the plurality of service nodes 102 in the distributed system in a communication manner.
The log display server is in communication connection with a plurality of service nodes in the distributed system respectively, and can be in communication connection through a Remote Procedure Call (RPC) protocol, so that the RPC framework actually provides a set of mechanism, so that the application programs can communicate with each other and conform to a server/client model; when the system is used, the client calls an interface provided by the server just like calling a local function; specifically, a GRPC protocol may be adopted, the GRPC has an advantage of a plurality of development languages supported by a cross-platform, and certainly, other RPC protocols may also be used to implement communication connection between the log presentation server and each service node in the distributed system. RPC is a protocol that requests services from a remote computer program over a network without knowledge of the underlying network technology. The RPC Protocol assumes the existence of some Transmission protocols, such as Transmission Control Protocol (TCP) or User Datagram Protocol (UDP), for carrying information data between communication programs. In an Open System Interconnection (OSI) network communication model, RPC spans a transport layer and an application layer, so that it is easier to develop an application program including a network distributed multi-program.
In other possible embodiments, the log display server and each service node in the distributed system may also implement communication connection by using a hypertext transfer Protocol (HTTP) or TCP.
The execution main body of the method is a log display server; as shown in fig. 2, the method comprises the steps of:
step S202, receiving log files sent by each service node, wherein the log files are running logs of corresponding service programs in the corresponding service nodes; the log file comprises log information and log content, wherein the log information comprises a service node name, a service program name and a log file name;
the service node can be understood as a log collection client; the log display server can receive a plurality of log files sent by a plurality of service nodes, wherein each log file is an operation log of a certain service program in each service node; the log content includes various types, such as logging in a system, upgrading software, modifying basic setting information, and the like; the service node name, the service program name and the log file name are generally automatically set and generated according to a system; service NODE name refers to the name of the current service NODE machine, e.g., NODE _ 1; the name of the SERVICE program refers to the name of which SERVICE program the current log file is about, such as SERVICE _ 1; log file names are used because a service program may have multiple log files, and each log file of the same service program has its own name, e.g., stdout. The log content refers to the text content of the log file.
Specifically, the log presentation server receives the log file in a format of < key1, key2, key3, value > through an RPC communication protocol, wherein the key1 is a service node name; key2 is the service name; key3 is the name of the log file; value is the log content.
Step S204, the log file is associated with the corresponding service program according to the log information;
since the log display server may receive a plurality of log files, the received log files need to be associated with the service program generating the log files according to the log information in the log files, so that when a user wants to obtain the log files generated by the service program, the corresponding log files can be displayed.
Specifically, the log file may be associated to a corresponding list of the log display server according to a service node name, a service program name, and the log file included in the log information.
A preferred embodiment:
analyzing the log information to obtain a service node name, a service program name and a log file name; according to the service node name, the log file is associated to a service node level list in a preset directory; according to the service program name, the log file is associated to a service program level list in a preset directory; and according to the name of the log file, associating the log file to a log file hierarchy list in a preset directory.
The pre-directory comprises a service node level, a service program level and a log file level, and the service node level, the service program level and the log file level respectively correspond to a service node name, a service program name and a log file name in log information; the log information can be analyzed by obtaining the key information of the first three of the received log files < key1, key2, key3, value >, and sequentially obtaining the service node name, the service program name, and the log file name corresponding to key1, key2, and key 3.
Specifically, in order to enable the log file to correspond to the log file requested to be viewed by the user, the log file may be associated to a service node hierarchy list in a preset directory according to the parsed service node name; according to the analyzed service program name, the log file is associated to a service program level list in a preset directory; and according to the name of the log file, associating the log file to a log file hierarchy list in a preset directory.
Step S206, when a log content viewing request of a user for a target service program in a target service node is obtained, a service program name list running in the target service node, a log file name list of the target service program and target log content are displayed according to the incidence relation between the log file and the service program.
The viewing request comprises a corresponding target service node and a target service program in the target service node; specifically, a target log file associated with a target service program in the target service node may be searched according to an association relationship between the log file and the service program, and the target log file obtained by the search may be displayed in a hierarchical directory manner.
For example, fig. 3 shows a directory of a log presentation server, where the log presentation server provides a front-end presentation service having an integrated service NODE machine list, in which service NODE names NODE _0, NODE _1, NODE _2, NODE _3, and NODE _4 of each service NODE machine are presented; an operation and maintenance person can check all SERVICE program names in a certain SERVICE NODE by clicking any one SERVICE NODE name, for example, after the operation and maintenance person clicks the SERVICE NODE name NODE _1, a log display SERVICE end displays all SERVICE program names SERVICE _0, SERVICE _1, SERVICE _2 and SERVICE _3 of the NODE _ 1; the operation and maintenance personnel can further click any one SERVICE program name to view all log file names of the SERVICE program, for example, after the operation and maintenance personnel click the SERVICE name SERVICE _1, the log display SERVICE end displays all log file names stdout. The operation and maintenance personnel can click any log file name, and then the log content of the log file can be obtained.
The method for displaying the logs of the service nodes in the distributed system is applied to a log display server and used for receiving log files sent by all the service nodes; associating the log file with a corresponding service program according to the log information included in the log file; and when the log content viewing request is acquired, displaying a service program name list operated in the target service node, a log file name list of the target service program and target log content according to the incidence relation between the log file and the service program. In the method, the distributed system comprises a plurality of service nodes, at least one service program runs in each service node, the log display service end is in communication connection with the service nodes in the distributed system respectively, the log file can be displayed to the log display service end in real time through the deployment method without complex components and with light weight, the deployment and maintenance cost is low, and meanwhile, the service operation and maintenance efficiency of the distributed system is improved.
The embodiment of the invention provides a log method for collecting service nodes in a distributed system, wherein the distributed system comprises a plurality of service nodes, at least one service program runs in each service node, each service node is in communication connection with a log display server, and the method is applied to the service nodes. As shown in fig. 4, the execution subject of the method is a service node, and the method includes the following steps:
step S402, acquiring a log file of a specified target service program in a configuration file according to the preset configuration file at intervals of a first preset period; the log file is an operation log of a corresponding service program in a corresponding service node; the log file comprises log information and log content, wherein the log information comprises a service node name, a service program name and a log file name;
the first preset period can be set between 1 and 30 seconds, and the specific duration can be determined according to actual needs; if the first preset period is short, the real-time performance of log updating is high, but the load on the whole distributed system is large; otherwise, the real-time performance of log updating is reduced, but the load of the whole distributed system is reduced. The preset configuration file is a computer file, can configure parameters and initial settings for some computer programs, and can perform different configuration files on different objects; specifically, according to actual requirements, if a log file of a certain service program is to be collected, the name of the service program may be configured into a configuration file.
The log file may include a plurality of log types, each determined by a different service, such as an application log, a Web and application server log, a garbage collector log, or a system log.
In this embodiment, taking setting to 1 second as an example for explanation, one possible way to obtain the log file may be to scan and obtain the log file of the target service program specified in the configuration file in a tail file (Tailfile) manner, and read the log file updated in the last first preset period line by line.
Step S404: and transmitting the log file to a log display server.
In this embodiment, the log file includes log information and log content, where the log information includes a service node name, a service program name, and a log file name.
Service NODE name refers to the name of the current service NODE machine, e.g., NODE _ 1; the name of the SERVICE program refers to the name of which SERVICE program the current log file is about, such as SERVICE _ 1; log file names are used because a service program may have multiple log files, and each log file of the same service has its own name, e.g., stdout. The log content refers to the text content of the log file.
When the service node transmits the log file to the log display service terminal, the log file can be transmitted through GRPC in the format of < key1, key2, key3 and value >; the keys 1, 2, 3 are generated based on the organization interface of the log display service end, and the keys 1, 2, 3 are respectively: the name of the service node, the name of the service program and the name of the log file, and the value is the log content. The service node can also be understood as a log collection client, and reports the log file to the log display server after collecting the log file in a first preset period of 1 second; and then displaying through the log display server.
In the method for aggregating service nodes and logs in a distributed system provided by the embodiment of the invention, each service node acquires the log file of the target service program appointed in the configuration file according to the preset configuration file at intervals of a first preset period, and then transmits the log file to the log display server, so that the log display server receives the log file capable of displaying each service node for the operation and maintenance personnel to screen and check. In the method, each service node is utilized to collect the log files in real time in a certain period and transmit the log files to the log display server, so that the log display server can display the log files to operation and maintenance personnel according to the preset directory, the efficiency of the operation and maintenance personnel for checking the log files is improved, the deployment and maintenance cost is low, and the technical problem of low service operation and maintenance efficiency of the existing distributed system is solved.
In a possible implementation manner, for a specific implementation manner of the step of acquiring the log file of the target service program specified in the configuration file in the step S402, the method includes:
step A1, determining a first target log file according to the target service program specified by the configuration file;

and step A3, acquiring the log records with the same number as the number of the pieces from the tail part of the first target log file according to the number of the pieces, and sending the log records as log files.
The types of the service programs are various, wherein some types of service programs can generate log records in real time and write the generated log records into log files; the log record in the first target log file is a real-time updated log file, and the first target log file is updated in real time according to the log record generated in real time by the service program, and the updating mode may be that new log records are sequentially added to the first target log file in a row mode. Therefore, in the case that the target service program generates a log record for a fact, in the embodiment, first, a first target log file may be determined according to the target service program specified by the configuration file; specifically, the number of newly added log records in the first target log file can be continuously scanned in a tail file (Tailfile) manner; according to the number, obtaining the log records with the same number as the number from the tail part of the first target log file as the log files and sending the log records to a log display end; in the method, the incremental log records are acquired in the incremental mode adaptively and are sent as the log file, and the newly generated log records can be displayed in real time aiming at the service program of the log records generated in real time.
