Description
Technical Field
The present invention relates to a communication network service health degree detection technology, and in particular, to a service health degree detection system and method.
Background
With the development of IP technology, the popularization of broadband, and the exponential growth of network users, the network traffic on the Internet is rapidly expanding, and various Internet services are increasing. In order to solve the above problem, a group of servers is usually used to provide services to users, and provide a single interface to the outside (i.e. the group of servers only provides one IP address to the outside for service).
Referring to fig. 1, fig. 1 is a solution to the above problem in the prior art, and a server load balancing device is used to detect the health of a server: the RS1 to RS7 are a group of servers that ultimately provide services, the server load balancing device is disposed in front of the group of servers, the server load balancing device has a group of virtual servers VS1 to VS3, each virtual server corresponds to a certain service class, such as service classes 1 to 3 in the figure, after a user service request reaches an operator service network, the service request is transmitted to the server load balancing device first, the server load balancing device distributes the service request to different virtual servers according to the class of the user service request, and the virtual servers forward the service request to corresponding background servers for processing. In this process, in order to ensure that the service achieves the effect satisfactory to the user, the server load balancing device needs to check the health of the background server to avoid distributing the user request to the device which cannot provide the service.
By health is meant the state of the relevant application service or host resource on the server, wherein,
the host resource health status includes: CPU utilization rate, memory utilization rate, service bandwidth occupancy rate, other key resources, such as process number, thread number, socket resource number, etc
The application service health status includes: the number of key resources affecting the response of the user, the concurrent processing capability, the number of currently consumed resources, resources including socket, application available thread, counter, background connection, memory, hard disk and the like, and all places where bottlenecks may exist;
generally, a server failure state is represented by a link failure, a host failure, and an application failure (also referred to as a service failure), and correspondingly, when the server failure is recovered, there are three other states, namely, a link recovery state, a host recovery state, and an application (service) recovery state, and how to detect these states to ensure reliability of the service has become a problem generally concerned by communication service operators.
The currently known methods for detecting the health of the server include the following methods:
in the first technical scheme, server health degree inspection is performed by using an Ethernet OAM technology.
OAM refers to Operation, Administration, and Maintenance (Maintenance), and the functions of the technology include: monitoring the performance, generating maintenance information, and evaluating the stability of the network according to the information; detecting network faults by a regular query method to generate various maintenance and alarm information; the normal operation of the network is ensured by scheduling or switching to other entities and bypassing the failed entity; the fault information is communicated to a management entity.
Ethernet OAM provides two-layer end-to-end monitoring and detection, and can detect the link state of server connection through two-layer switching equipment. However, the technology can only detect the link state, cannot detect the state of the server host, and has great dependence on peripheral equipment, which is not beneficial to application.
In the second technical scheme of the prior art, a ping method is used for monitoring degree check.
The monitoring degree check by using the ping method is a common server detection method, and the realization method is very simple: and sending ping messages to each appointed IP address by adopting a timer on the equipment at regular intervals, detecting whether a response exists, if so, indicating that the server is healthy, and otherwise, indicating that the server has failed.
Although the method has the advantages of simple implementation method, good technical expansibility and the like, the method can be shielded by a host, meanwhile, frequent pings are easily identified as attack messages, related ping services need to be started on the preposed equipment, IP addresses need to be configured on the security router and the host, and the method can conflict with a monitoring network.
In the third prior art, health degree examination is performed by using an arp (address resolution protocol) method.
The inspection of the monitoring degree by the arp method is a common method, and the method is implemented as follows: the method comprises the steps of periodically sending an arp message to each appointed IP address by adopting a timer on equipment for carrying out address request, detecting an arp response message, if the arp response message has a response, indicating that a server is healthy, and otherwise indicating that the server is invalid.
The method has the advantages of simple implementation method, small attacked risk and the like. But the method can only be applied to two-layer network networking and has poor expansibility; only host state detection can be provided, and service state detection cannot be provided; may conflict with the monitoring network.

The service health degree detection method provided by the invention is characterized in that the preposed equipment comprising the inquiry end initiates a health degree inquiry request to the host comprising the inquiry agent and the service response end, inquires the host state and the service state of the host, and the host sends the service state and the host state response to the preposed equipment. By the method, the host state and the service state of the host can be detected without omission, the preposed equipment is ensured not to distribute the user request to the host which can not provide the service when the service is distributed, and meanwhile, the service health degree detection with different frequencies can be realized between the preposed equipment and the host, so that the aims of improving the detection efficiency and saving the system resources are fulfilled. The embodiment of the invention provides three specific implementation methods: query-response methods, registration-notification methods, and registration-query methods.
The host state, i.e. the host health state, in the above method and system includes: the state of key resources such as CPU utilization rate, memory utilization rate, service bandwidth occupancy rate, process number, thread number, socket resource number and the like; the service state, i.e., the service health state, includes: concurrent processing capacity, the number of currently consumed resources, the number of socket resources, application available threads, counters, background connections, the state of other application table entry resources such as a memory, a hard disk, the number of sessions, the number of nat addresses and the like.
Referring to fig. 2, a schematic diagram of the service health detection system of the present invention is shown. The system includes a user, an operator service network, and an operator service device. The operator service equipment comprises a front-end device and a host. The front-end device is used for detecting the service health degree of the host. The prepositive equipment is provided with an inquiry end;
the query end is a general name of a query client and a query agent on the front-end equipment and is used for initiating a query request to the host computer;
the query client, which may also be referred to as a query request initiator, refers to a specific application on a front-end device that needs to obtain a server state;
the inquiry agent works on the front equipment and is used for transmitting an inquiry request initiated by an inquiry client and providing encapsulation and analysis services for the information of the inquiry client.
The host is used for providing services for users, and the host is provided with a query agent, a service response end and a storage module. Wherein,
the inquiry agent works on the host machine, is used for initiating, responding and forwarding an inquiry request from the front equipment, can realize inquiry of an iterative method through the inquiry agent, namely a response end for service health degree check is simultaneously an inquiry end for another service health degree inquiry, and can provide the host machine state of the response end;
the service response end, the application service on the host computer to be queried, needs to feed back the health of the relevant service.
And the storage module is used for caching the service state and the host state.
In the system shown in fig. 2, a user initiates a service request to an operator service network, the operator service network sends the request to a front-end device after receiving the service request of the user, the front-end device detects host states and service states of a group of connected host computers through an inquiry end or reads host states and service states of a host computer stored on the host computer, and then distributes the service request to the host computer with good health according to a predetermined rule.
Meanwhile, it should be noted that the user referred to in the system is not a person or an organization in a general sense, but includes all mechanisms for initiating a service request to an operator, and may be a person or some intermediate device or terminal. The operator referred to in the present system is not only an operator in a general sense, but also includes all individuals, organizations, intermediate devices, terminals, and the like that provide a certain application.
In addition, the query side of the front-end device proposed in the system comprises a query client and a query agent, and the host comprises the query agent and a service response side, but the concept of the invention is not limited to this, and any action of recombining or dividing the functions is within the concept of the invention.
The first service health degree detection method disclosed by the invention is based on a query-response method. The front-end equipment sends a health degree query request to the host, and the host sends a health degree query response to the front-end equipment. The specific implementation method comprises three operations: the method comprises the steps that the front-end equipment inquires the instant service state on the host, the service state cached on the host and the state of the host. Therefore, service health degree query with different frequencies can be realized between the preposed equipment and the host, namely, the query agent on the query end-host can perform query and response with high frequency, and the host-service performs query and response with low frequency. This will be described with reference to the accompanying drawings.
Fig. 3 shows a flowchart of a health detection method based on a query-response method in an embodiment of the present invention, which includes the following steps:
301. the method comprises the steps that a front-end equipment inquiry end initiates a health degree inquiry request to a host inquiry agent, and the inquiry can be an instant service state or a host state or a service state or a host state cached on a host according to a specific condition;
302. after receiving the health degree query request, the host query agent judges the type of the request, and if the query request is an instant service state, executes step 303; if the request is for the service state or the host state cached on the host, go to step 306;
303. the host inquiry agent initiates an inquiry request for inquiring the instant service state to a host service response end;
304. the host server response end feeds back the instant service state to the host inquiry agent;
305. after receiving the instant service state information of the service response end in step 304, the host inquiry agent forwards the information to the front equipment inquiry end;
306. after receiving a health query request for querying the service state and the host state of the local cache or the instant host state, the host query agent reads the service state or the host state of the local cache from the storage module or acquires the instant host state;
307. the host query agent sends the cached service state or host state obtained in step 306 to the front-end device query side.
By the method, service state inquiry with different frequencies can be realized, service or host resources with higher performance requirements can be inquired at any time, service or host resources with not higher performance requirements can be cached on a storage module of the host at a certain period, and when the inquiry is needed, the stored information can be read. For the cached host state or service state, it may be specified that as long as the obtained cached service state or host state is healthy, it may be determined that the service or host resource is healthily available.
The invention discloses another service health degree detection method based on a registration-notification method. Firstly, the prepositive device registers the service to be inquired on the host, and after the registration is finished, the host inquiry agent periodically sends the registered service state information to the prepositive device. Thus, the front-end device does not need to make frequent host service status queries as long as the host query agent is healthy. The method comprises the steps of service registration, agent health inquiry, host state inquiry and the like. As will be described in detail below.
Fig. 4 is a flowchart of a service health degree detection method based on a registration-notification method in an embodiment of the present invention, which specifically includes the steps of:
401. the front-end equipment inquiry end completes local inquiry service registration, the setting is to inquire the local health degree of the front-end equipment, and the inquiry content also comprises a service state and a host state;
402. the preposed equipment inquiry end inquires an agent request to a host for carrying out inquiry service registration;
403. after receiving the query service registration request, the host query agent determines the type of the service requiring query registration, and if the service is to be registered, executes step 404; if the service state or the host state cached on the host is to be registered, execute step 407;
404. the host inquiry agent requests the host service response end to perform instant service state inquiry registration;
405. after receiving the registration request, the host service response end completes the instant service state inquiry registration and feeds back the instant service state to the host inquiry agent according to the registration condition;
406. the host inquiry agent notifies the front-end equipment inquiry end of the instant service state acquired in the step 405;
407. host inquiry agent inquires service state and host state of local buffer;
408. the host inquiry agent notifies the cache service state or the host state acquired in step 407 to the front-end device inquiry terminal according to the registration condition.
In the above process, the following may be further included:
the method comprises the steps that after the front-end equipment requests a host to inquire service registration, a message for inquiring whether the inquiry service registration is successful or not is sent to an inquiry agent of the host, if the inquiry service registration is successful, the front-end equipment inquiry end does not perform other operations, and if the inquiry service registration is failed, the inquiry service registration request can be initiated again;
the front-end equipment inquiry end sends an agent health inquiry request to the host inquiry agent, if the front-end equipment receives the inquiry response of the host inquiry agent, the host inquiry agent is considered to be healthy, otherwise, the host inquiry agent is judged to be invalid, and further the host is judged to be invalid.
It should be noted that, in the method, the host may be configured to send the state of the registered service or the host state to the front-end device according to a certain time period as described above, or the host may be configured to send the state change information to the front-end device only when the host state changes or the registered service state changes. The method specifically comprises the following steps:
when the host state of the host computer changes, the host computer query agent sends a host state change message to the preposed equipment query end, and the preposed equipment query end sends a state change response to the host computer query agent after receiving the state change message;
when the service state of the host changes, the service response end of the host sends a service state change message to the preposed equipment inquiry end, and the preposed equipment inquiry end sends a state change response to the service response end of the host after receiving the state change message.
The invention also discloses a service health degree detection method based on the registration-query method. In the present method, the service registration method involved is exactly the same as the registration method in the registration-notification method described above. The difference is that in the method, the pre-device not only passively waits for the host to send the registered service state or the host state, but also can set a certain condition, and when the set condition is met or a temporary requirement occurs, the pre-device actively queries the host state and the service state of the host. The method will be specifically described below.
Fig. 5 is a flowchart illustrating a service health degree detection method based on a registration-query method in an embodiment of the present invention, which specifically includes:
501. the front-end equipment inquiry end completes local inquiry service registration, the setting is to inquire the local health degree of the front-end equipment, and the inquiry content also comprises a service state and a host state;
502. the preposed equipment inquiry end inquires an agent request to a host for carrying out inquiry service registration;
503. after receiving the query service registration request, the host query agent determines the type of the service requiring query registration, and if the service is to be registered, executes step 504; if the service state or the host state cached on the host computer is to be registered, execute step 507;
504. the host inquiry agent requests the host service response end to perform instant service state inquiry registration;
505. after receiving the registration request, the host service response end completes the instant service state inquiry registration and feeds back the instant service state to the host inquiry agent according to the registration condition;
506. the host inquiry agent notifies the front-end equipment inquiry end of the instant service state acquired in the step 505;
507. host inquiry agent inquires service state and host state of local buffer;
508. the host inquiry agent notifies the cache service state or the host state acquired in step 507 to the front-end device inquiry terminal according to the registration condition.
The above steps are used to conventionally obtain the registered service state and host state, and when the preset condition exceeds the set condition during registration, the prepositive device still does not receive the notification information of the host or generates a specific query requirement, the scheme can also realize the following steps:
509. the preposed equipment inquiry end sends a health degree inquiry request to a host inquiry agent, and if the health degree inquiry request cannot receive the response of the host inquiry agent after a period of time, the host is judged to be invalid;
510. the host querying agent determines whether the requested querying service is registered, and if the requested querying service is registered, step 511 is executed; if the service is not registered and the query request is in an instant service state, go to step 513; if the service is not registered and the query request is a service state or a host state cached on the host, go to step 516;
511. the host computer inquiry agent calls the registered function to obtain the corresponding service or host computer state;
512. the host inquiry agent sends the service state information acquired in the step 511 to the front equipment inquiry end;
