The details are as follows:
s101: and the node server deploys and starts the update monitoring of the Logstash configuration file by using the epoll model.
In the embodiment of the present invention, a node server is a server device in a server cluster, where a server cluster refers to a cluster system that performs the same service in a centralized manner on a plurality of servers and performs parallel computation using a plurality of computers to increase the computation speed, a log is a log collection processing tool in an elastic search log library (ELK) analysis system, and a log collection processing tool is installed on each server in the node servers.

Specifically, in the updating monitoring process, a file descriptor is created first, if one or more events connected to the network connection port are detected, the event processing thread is set to be in a non-blocking state, the events are registered in the file descriptor for processing, meanwhile, the processing states of all events registered in the file descriptor are monitored, if the event processing is completed, the state information of all event processing is traversed, and when the event processing is completed, the network connection port is confirmed to be in an idle state, and the event processing thread is set to be in a blocking state. The file descriptor is used for accessing or creating a file and is a nonnegative integer, and the network connection port is a connection end between the node server and the management server.
S102: the node server sends the heartbeat packet to the management server at regular time.
In the embodiment of the present invention, a node server sends a heartbeat packet to a management server at a preset time interval through a heartbeat service, where the heartbeat packet is used to detect a link state of a network connection port, where the heartbeat packet includes, but is not limited to, an IP address of the node server and version information of a logstack configuration file, and specifically, the heartbeat service implements communication connection between the node server and the management server by using a hypertext Transfer Protocol (HTTP) and a Transmission Control Protocol (TCP), where the preset time may be 1 second or 1 minute, and specifically, the preset time may be set according to needs of actual applications, and is not limited here.
S103: the management server establishes a management client.

Further, if the user needs to use the management client to perform a management operation on the node server, the user is required to input a user name and a password at the management client, verify whether corresponding data information is stored in a database of the management server, and if the verification is passed, the user can log in the management client, and ownership of the node server is managed, such as node server management and other operations. If the verification fails, the login fails, information of wrong user names and passwords is output on an interactive interface of the management terminal, the fact that the user does not have the right to log in the management client terminal to perform management operation on the node server is shown, and the security of the cluster system is improved.
S104: and the management server receives the heartbeat packet sent by the node server and starts heartbeat monitoring on the node server according to the heartbeat packet.
In the embodiment of the method, the management server judges whether the link state of the network connection port of the node server corresponding to the heartbeat packet is normal or not by receiving the heartbeat packet sent by the node server, starts heartbeat monitoring on the node server according to the heartbeat packet and monitors the state information of the node server in real time.
Specifically, the management server can timely find an abnormality through heartbeat monitoring, for example, if a heartbeat packet sent by a certain server in the node servers is not received within a period of time, the management server confirms that the link state of the server is abnormal, and timely displays the abnormal condition on an interactive interface of the management client, so that related maintenance personnel can timely analyze and process related abnormal problems appearing on the corresponding node server.

S106: and the management server sends the cluster management instruction to the node server.
In the embodiment of the method, the cluster management instruction includes identification information of the node server to be managed and a specific operation instruction, and the identification information of the node server may specifically be an IP address of the node server.
For example, if a user needs to delete a certain server in the Node servers, the user may execute a management operation of "delete Node server" in a management operation interface of the management client, fill in an IP address "192.168.0.111" of the Node server that needs to be deleted, and the management client automatically generates a corresponding management instruction "Remove Node 192.168.0.111" according to the management operation and the IP address and sends the corresponding management instruction to the corresponding Node server.
S107: and the node server receives the cluster management instruction sent by the management server and performs cluster management according to the cluster management instruction.
Specifically, when the node server receives a cluster management instruction sent by the management server, the node server analyzes the cluster management instruction and performs corresponding cluster management according to an analysis result.

In the embodiment of the method, the configuration updating operation is the updating operation that a user modifies the content of the configuration file of the current logstack to generate an update file, and inputs the IP address of the node server to be updated in an update address.
Specifically, if the function of the logstack log collection system needs to be changed according to the service requirement, if the log information of a new service needs to be added to the current logstack log collection system for collection, or the log information output address of the logstack log collection system needs to be changed, the user performs configuration update operation on the management client according to the service requirement, and updates the content of the current logstack configuration file of the node server in the cluster.

In the embodiment of the method, if one or more event connections are detected at a network connection port, an event processing thread is set to be in a non-blocking state, a corresponding file descriptor is created according to the event, an epoll _ ctl () function provided by an epoll model is called to register the created file descriptor in the epoll file descriptor for event processing, the event processing specifically comprises event processing such as registering the event, modifying the event, deleting the event and performing read-write operation on the event, if the event processing is successful, an event processing success instruction is returned, otherwise, an event processing failure instruction is returned.
S203: and the node server monitors the processing state information of the event, and sets the event processing thread to be in a blocking state if detecting that the network connection port is in an idle state.
Specifically, an epoll _ wait () function provided by an epoll model is called to monitor Processing state information of all events registered in a file descriptor, a Processing state of an Input/Output (I/O) event is polled based on the events registered in the file descriptor, if an event Processing success instruction or an event Processing failure instruction returned by the epoll _ ctl () function is monitored, state information of all event Processing is traversed, when all event Processing is completed, a network connection port is confirmed to be in an idle state, an event Processing thread is set to be in a blocking state, idle resources are subjected to data information such as handle closing, monitoring process closing, event Processing thread closing and message queue closing, and Central Processing Unit (CPU) destruction resources are released.
