Background
At present, with the rapid development of enterprises, the types of services are more and more abundant, the number of the accompanying projects is more and more, and the single-machine deployment mode is difficult to meet the service requirements. In order to meet the service requirements, a micro-service architecture and a clustering deployment mode are generally adopted, and the number of used servers is multiplied, so that the health state (whether a request can be responded or not and whether the server runs normally) of the server is difficult to monitor.
In the prior art, there are two main methods for monitoring the health status of a server, one is a heartbeat detection mechanism based on a registration center in a micro-service architecture, the server sends a heartbeat message (for example, using a TCP/UDP protocol) to the registration center at a fixed time, and if the registration center replies with a heartbeat within a configured time range, the health of the server is indicated. The other method is to check API call regularly, the monitored server provides an API interface, the server health monitoring system sends HTTP request regularly to the interface, and judges whether the server is normal or not according to the interface return result.
However, the above-mentioned solutions cannot adapt to a complex network environment, for example, some projects of an enterprise are deployed in different rooms of an internal network, networks of the rooms are isolated from each other, some projects are deployed in an external network, and if only a health check server is deployed in one room, it may not be possible to perform health monitoring on servers of all the projects. In addition, the above scheme fixes the parameters configured for the health check server, and the period of the timing check is fixed for each monitored server, so that the customization cannot be realized. Moreover, the above solution determines the health status of the server by comparing the returned result with the expected returned result in the health parameters, however, as the data changes, the returned result may be similar to and unequal to the expected returned result, and at this time, a misjudgment may be made. In addition, because the network may have fluctuation, the above scheme only returns the result once to judge whether the server is healthy or not.
Therefore, a server health monitoring method and system are needed to solve the problems in the above technical solutions.

As shown in FIG. 1, the server health monitoring system 100 includes a client 110, a health monitoring server 120, a state machine module 125, and one or more check servers 130. Each of the examination servers 130 may be communicatively connected to one server 150 to be monitored, and the health monitoring server 120 may be communicatively connected to the client 110 and one or more examination servers 130, for example, through a wired or wireless network.
The health monitoring server 120 is used for managing and controlling the one or more checking servers 130 to check the health status of the servers 150 to be monitored at regular time, so as to realize the health monitoring of the one or more servers 150 to be monitored. The present invention is not limited to the specific type of the health monitoring server 120, for example, the health monitoring server 120 may be implemented as a computing device such as a desktop computer, a notebook computer, a processor chip, a mobile phone, a tablet computer, etc., but is not limited thereto, and may also be an application program residing on the computing device.
The client 110 is a terminal device used by a user, and may specifically be a personal computer such as a desktop computer and a notebook computer, or may also be a mobile phone, a tablet computer, a multimedia device, an intelligent wearable device, and the like, but is not limited thereto.
In the embodiment of the present invention, the health monitoring server 120 periodically sends health check requests to one or more checking servers 130, so that the checking servers 130 send requests to corresponding servers 150 to be monitored based on the health check requests, and obtain request results returned by the servers 150 to be monitored. After acquiring the request result returned by the server 150 to be monitored each time, the check server 130 stores the request result in the memory queue of the check server 130. Thus, the memory queue of the checking server 130 may contain one or more request results returned by the server 150 to be monitored connected thereto.
And, the health monitoring server 120 regularly obtains the request result in the memory queue of each checking server 130, and determines the health status of the server 150 to be monitored corresponding to the request result at the time point when the request result is returned by analyzing the request result.
In one embodiment, the inspection server 130 may be implemented as an Agent proxy server. The user may register information for one or more check servers 130 at client 110 and register information for one or more servers to be monitored 150 and send to health monitoring server 120. Here, the check server information includes, for example, a name (Agent name) of the check server, an address, an access key, a description, and the like. Here, the access key is, for example, a Token key. The server information to be monitored includes, for example, one or more of an item name, a service name, a request protocol, a health check request address, a request parameter, a request time interval, an allowed timeout time, a maximum number of retries, a check server name, and an alarm mailbox.
The health monitoring server 120, after receiving the information of one or more checking servers registered by the user at the client 110 and the information of one or more servers to be monitored, may bind the server 150 to be monitored with a corresponding one of the checking servers 130 according to the information of the server to be monitored (checking server name).
In one embodiment, as shown in FIG. 1, health monitoring server 120 includes a management module 121, a monitoring module 122 connected to client 110. The monitoring module 122 may establish a communication connection with one or more inspection servers 130, so as to periodically send health inspection requests to one or more inspection servers 130 and periodically obtain the request results in the memory queue of each inspection server 130. The monitoring module 122 analyzes the request result to determine the health status of the server 150 to be monitored corresponding to the request result at the time point when the request result is returned.
The management module 121 may acquire information of one or more check servers registered by the user at the client 110 and manage the check server information. The monitoring module 122 may obtain information of one or more servers to be monitored registered by the user at the client 110, and store the registered server information to be monitored in the structured data storage device, so as to manage the server information to be monitored. Also, the monitoring module 122 may bind the server 150 to be monitored with a corresponding one of the check servers 130 according to the server information to be monitored (check server name).
In one embodiment, after acquiring the information of the one or more monitoring servers registered by the client 110, the health monitoring server 120 may set a corresponding timing task for each server 150 to be monitored, and configure a thread for each server 150 to be monitored to execute the corresponding timing task.
In this way, the health monitoring server 120 starts a thread for each server 150 to be monitored in the memory to execute the timing task of the server 150 to be monitored, so as to send the health check request of the server 150 to be monitored to the check server 130 connected to the server 150 to be monitored at regular time, and obtain the request result returned by the server 150 to be monitored stored in the memory queue of the check server 130 at regular time, and analyze the health status of the corresponding server 150 to be monitored according to each request result.
In one embodiment, the health monitoring server 120, after determining the health status of the server to be monitored 150 (i.e., the health status of the server to be monitored 150 at the time point when the request result is returned) by analyzing the request result of the server to be monitored 150, also determines whether the health status of the server to be monitored 150 has changed, i.e., determines whether the health status of the server to be monitored 150 has changed from the health status at the time point when the last request result was returned. If a change occurs, a corresponding server health status change notification is sent to the client 110. For example, a server health status change notification may be sent to an alarm mailbox corresponding to the server 150 to be monitored, so as to inform the user of the current server health status.
In one embodiment, the monitoring module 122 of the health monitoring server 120 is connected to a State Machine module 125, and the State Machine module 125 may be implemented as, for example, a FSM (Finite State Machine). The monitoring module 122 of the health monitoring server 120 sends a signal (e.g., a health signal, a maintenance signal, an abnormal signal) corresponding to the health status of the server 150 to be monitored to the state machine module 125, and the state machine module 125 can determine whether the health status of the server 150 to be monitored changes according to the signal corresponding to the health status. The state machine module 125 may send a corresponding server health status change notification to the client when it is determined that the health status of the server 150 to be monitored changes.
In one embodiment, the checking server 130 is adapted to send an HTTP request to the server to be monitored 150 connected thereto, and obtain the HTTP request result returned by the server to be monitored 150. After obtaining the HTTP request result from the memory queue of the checking server 130, the health monitoring server 120 may determine the health status of the server 150 to be monitored corresponding to the request result according to the status code and the response body by obtaining the status code and the response body from the HTTP request result. Here, the health state includes one or more of health, maintenance, and abnormality.
In one embodiment, the health monitoring server 120 is configured to perform the server health monitoring method 300 of the present invention, the server health monitoring method 300 of the present invention being described in more detail below.

Also, the monitoring module 122 of the health monitoring server 120 may bind the server to be monitored 150 with a corresponding one of the check servers 130 according to the server information to be monitored (check server name).
In step S320, the request result in the memory queue of each inspection server is obtained at regular time, and the health status of the server 150 to be monitored corresponding to the request result at the time point when the request result is returned is determined by analyzing the request result.
According to an embodiment of the present invention, after acquiring information of one or more monitoring servers registered by the client 110, the health monitoring server 120 may set a corresponding timing task for each to-be-monitored server 150, and configure a thread for each to-be-monitored server 150 to execute the corresponding timing task.
In this way, when steps S310 and S320 are executed, the health monitoring server 120 starts a thread for each server 150 to be monitored in the memory to execute the timing task of the server 150 to be monitored, so as to periodically send the health check request of the server 150 to be monitored to the checking server 130 connected to the server 150 to be monitored, and periodically obtain the request result returned by the server 150 to be monitored stored in the memory queue of the checking server 130. Here, in one implementation, after the request result in the memory queue of the checking server 130 is obtained periodically, the obtained request result may be stored in the structured data storage device, and then the health status of the corresponding server 150 to be monitored at the time point of the return of the request result is analyzed according to each request result by traversing each request result in the structured data storage device.
It should be noted that the present invention can satisfy the health status monitoring requirements of different servers to be monitored by setting different timing tasks for each server 150 to be monitored, and starting a thread for each server to be monitored to execute the timing task to periodically check the health status of each server to be monitored.
It should be noted that the health check request to be monitored, which is periodically sent to the check server 130 by the health monitoring server 120, includes the access key and the health check parameter of the check server 130. Here, the access key is, for example, a Token key. In one embodiment, the health check parameters include a request protocol, a request address, request parameters, an allowed timeout time, a maximum number of retries, etc. of the server to be monitored. Here, the permitted timeout time is a response timeout time permitted when the check server 130 transmits a request to the corresponding server to be monitored 150, and the maximum number of retries is a maximum number of times when the check server 130 retransmits a request after failing to transmit a request to the corresponding server to be monitored 150.
In one embodiment, after receiving the health check request periodically sent by the health monitoring server 120, the checking server 130, when sending a request to the corresponding server to be monitored based on the health check request, specifically, by obtaining the health check parameters from the health check request, and constructing an HTTP request based on the health check parameters, and then sending the HTTP request to the corresponding server to be monitored 150. After that, the check server 130 may obtain the HTTP request result returned by the server to be monitored 150.
In an embodiment, when the health status of the corresponding server 150 to be monitored is determined by analyzing the request result, the status code and the response body may be specifically obtained from the HTTP request result, and the health status of the server 150 to be monitored corresponding to the request result at the time point when the request result is returned is determined according to the status code and the response body. Here, the health state includes one or more of health, maintenance, and abnormality. That is, it can be determined whether the server to be monitored 150 is in a healthy, maintenance state, or abnormal state at the time point corresponding to the HTTP request result returned to the check server 130, according to the status code and the responder from the HTTP request result.
It should be noted that the state code and the responder corresponding to different health states are different. For example, "healthy" corresponds to a status code that is greater than or equal to 200 and less than 400. The maintaining state corresponds to a custom state code 503, and the response body includes a "maintaining" field. Based on this, if the status code in the request result is less than 200, greater than or equal to 400, and not equal to 503, it may be determined that the server to be monitored corresponding to the request result is in an abnormal state.
It should be noted that the present invention is not limited to the above-mentioned classification of health status and corresponding status code, and the type of server health status and corresponding status code can be defined and adjusted by those skilled in the art according to the actual situation.
According to an embodiment of the present invention, the health monitoring server 120, after determining the health status of the server 150 to be monitored (i.e., the health status of the monitoring server 150 at the time point when the request result is returned) by analyzing the request result of the server 150 to be monitored, also determines whether the health status of the server 150 to be monitored changes, i.e., determines whether the health status of the server 150 to be monitored changes with respect to the health status at the time point when the last request result was returned. If a change occurs, a corresponding server health status change notification is sent to the client 110. For example, a server health status change notification may be sent to an alarm mailbox corresponding to the server 150 to be monitored, so as to inform the user of the current server health status.
In one embodiment, health monitoring server 120 is coupled to State Machine module 125, and State Machine module 125 may be implemented as a FSM (Finite State Machine). The health monitoring server 120 may determine whether the health status of the server 150 to be monitored changes by:
the signals (e.g., health signals, maintenance signals, abnormal signals) corresponding to the health status of the server 150 to be monitored are sent to the state machine module 125, so that the state machine module 125 determines whether the health status of the server 150 to be monitored changes according to the signals corresponding to the health status. When determining that the health status of the server 150 to be monitored changes, the state machine module 125 sends a corresponding server health status change notification to the client, so that the user can know the current health status of the server 150 to be monitored in real time.
Specifically, by creating a state machine (FSM instance) for each server 150 to be monitored in the state machine module 125, after the health monitoring server 120 sends a signal (e.g., a health signal, a maintenance signal, or an abnormal signal) corresponding to the health status of any server 150 to be monitored to the state machine module 125, the state machine corresponding to the server 150 to be monitored is used to determine whether the health status of the server 150 to be monitored changes.
For example, if the current state of the state machine is "healthy", it indicates that the current health state of the server 150 to be monitored corresponding to the state machine is healthy, and after the state machine receives the exception signal next time, the state machine enters an exception state and determines that the health state of the server 150 to be monitored changes, and then sends a notification of "server exception" to the client 110. If the current state of the state machine is "healthy", after the state machine receives the maintenance signal next time, the state machine enters the maintenance state and determines that the health state of the server 150 to be monitored changes, and then sends a "server maintenance" notification to the client 110. In addition, if the current state of the state machine is "healthy", when the state machine receives a health signal next time, the health signal is a spin signal for the current state machine, the state of the state machine is not changed, and it is determined that the health state of the server 150 to be monitored is not changed.
According to the server health monitoring method 300, health check requests are sent to one or more check servers at regular time, so that HTTP requests are sent to corresponding servers to be monitored through the check servers and request results returned by the servers to be monitored are obtained, the request results returned by the servers to be monitored at various time points are obtained from the memory queue of the check servers at regular time, and the health states of the servers to be monitored at different time points can be analyzed and determined according to the request results returned by the servers to be monitored at various time points. Therefore, the current health state of the server to be monitored can be accurately analyzed. And whether the health state of the monitoring server changes or not can be judged, and when the health state of the monitoring server changes, the health state change notification of the monitoring server is sent to the user, so that the user can know the current health state of the server to be monitored in real time.
Furthermore, different timing tasks are set for each server to be monitored, a thread is started for each server to be monitored to execute the timing tasks, and the health state of each server to be monitored is checked at regular time, so that the health state monitoring requirements of different servers to be monitored can be met.
