Description
Technical Field
The present invention relates to the field of server snapshots, and in particular, to a snapshot service method and apparatus for an application server.
Background
With the continuous development of internet technology, the number of application servers in a cluster is increasingly huge, and because the failure of an application server in a cluster is often short in duration and is difficult to be checked by operation and maintenance personnel at the first time, the monitoring strength of the operation and maintenance personnel on the working condition of the application server is gradually reduced. Based on the above situation, operation and maintenance personnel urgently need to be able to master the fault condition monitoring and collection of the application server in the operation stage, so that the snapshot service of the application server is generated at the discretion of the operation. The snapshot service can quickly respond when the application server fails, and acquires software and hardware running condition information under the condition of responding to the failure according to the snapshot rule, thereby providing favorable help for operation and maintenance personnel to solve the failure of the application server.
However, in the prior art, the snapshot rule of the snapshot service is fixed, customization is insufficient, and operation and maintenance personnel can only set the rule by using the snapshot rule provided by the snapshot service by default; in addition, the snapshot service only supports the execution of one snapshot rule, and the amount of content monitored by the application server in the snapshot rule is also strictly limited, so that the fault information cannot be comprehensively collected.
Therefore, it is obvious that providing a snapshot service method of an application server to improve the customizable degree of a snapshot rule and collect failure information of the application server more comprehensively is a problem to be solved by those skilled in the art.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
The core of the invention is to provide a snapshot service method and a snapshot service device of an application server, so that the customization degree of a snapshot rule is higher, and when the application server fails, the related information of the failure can be more comprehensively collected.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example one
Fig. 1 is a flowchart of a snapshot service method of an application server according to an embodiment of the present invention. Referring to fig. 1, the snapshot service method of the application server includes the following specific steps:
step S10: at least two snapshot rules are obtained.
It can be understood that, since the amount of content monitored for the application server is strictly limited in a snapshot rule, only part of the application server information can be monitored in a snapshot rule. Therefore, the advantage of acquiring multiple snapshot rules is that the information of the application server can be monitored more comprehensively, and the user can set multiple types of monitoring contents in different snapshot rules according to the needs, so that the customization is stronger.
Step S11: the execution time of the snapshot rule is set in a timer.
The snapshot rules are constrained in execution time by a timer, and each time the execution time of one snapshot rule reaches a threshold set by a user, the snapshot rule stops executing and the next snapshot rule is executed. It will be appreciated that the execution time depends on the specific needs of the user, but should be relatively short in order to achieve the effect that all snapshot rules proceed simultaneously as much as possible.
Step S12: and the control timer executes the snapshot rules in sequence according to the execution time.
In this step, the execution of the snapshot rule is controlled according to the time of the snapshot rule set in the timer, so that the purpose of realizing the snapshot of various snapshot rules is achieved.
The snapshot service method of the application server provided by the invention realizes that the plurality of snapshot rules are executed in sequence according to the execution time by setting the execution time of the snapshot rule. The method has the advantages that although the number of the contents monitored by the application server in each snapshot rule is strictly limited, the purpose of increasing the number of the contents monitored by the application server can be achieved by executing a plurality of snapshot rules, so that the information when the application server fails can be more comprehensively collected. In addition, since a plurality of snapshot rules can be executed, a user can customize the corresponding snapshot rule according to needs and apply the corresponding snapshot rule to the application server snapshot service, so that the snapshot rule is not limited to the content provided by the snapshot service by default, and the customization degree of the snapshot rule is higher.
Example two
Fig. 2 is a flowchart of another snapshot service method of an application server according to an embodiment of the present invention. Steps S10-S12 in FIG. 2 are the same as those in FIG. 1, and are not repeated herein.
As shown in fig. 2, based on the above embodiment, as a preferred implementation, after acquiring at least two snapshot rules, the method further includes:
step S20: and establishing an interface for editing the snapshot rule in an annotation mode.
In the prior art, a DOM-mode stream model mode is generally used to read the XML configuration file to modify or edit the snapshot rule, but the snapshot rule is edited and modified in a configuration file mode, so that a large number of configuration files exist in an application server, configuration file redundancy is caused, and readability is reduced. Therefore, after the interface for editing the snapshot rule is established in the snapshot rule in an annotation mode, the editing operation of the snapshot rule can be realized through the interface, so that the operation of frequently writing the configuration file for editing the snapshot rule is avoided, the file redundancy is reduced, and the efficiency of editing the snapshot rule is improved. It is emphasized that, since there are many types of monitoring for the application server, the kinds and number of interfaces should be specifically determined according to different kinds of snapshot rules.
On the basis of the above example, the annotation is in particular the HK2 annotation, as a preferred implementation.
Since HK2 is a powerful lightweight annotation framework, it occupies less resources of the application server as a whole, and therefore has little impact on the performance of the application server.
On the basis of the above embodiment, as a preferred implementation, the interface is specifically a REST interface.
The REST interface is an interface type which accords with the REST standard, the overall style is simple and clear, the readability of the code is higher, and a series of operations such as the optimization of the interface in the later period are facilitated.
For a clearer understanding of the above embodiments, the following description will be made for a certain operation step of establishing an interface, but not specifically limited thereto:
annotating @ Configured for each tag interface class in the data model, after the annotation is successful, the DOM parser parses an XML configuration file according to attributes and elements specified in the tag interface class, reads snapshot rules, and issues the tag interface as an REST interface after the annotation is performed through HK 2.
As shown in fig. 2, on the basis of the above embodiment, as a preferred implementation, the method further includes:
step S21: it is determined whether a change has occurred to the snapshot rule, and if so, step S22 is performed.
Step S22: the snapshot rule is restarted.
It can be understood that, after the snapshot rule is changed, the snapshot rule should be executed again, which can ensure that the updated snapshot rule can be immediately applied to the snapshot service, thereby avoiding the situation that the information collected by the snapshot does not meet the user requirement when the application server fails. The specific execution order of the step is not limited, and the step may be performed after or simultaneously with any of the steps.
As shown in fig. 2, based on the above embodiment, as a preferred implementation, when the snapshot rule changes, the method further includes:
step S23: determining whether the snapshot rule applies to other target application servers in the application server cluster,
if so, step S24 is performed.
Step S24: the snapshot rule is synchronized to the target application server and the process proceeds to step S22.
Since application servers are often in an application server cluster environment, and some snapshot rules are commonly used by some application servers in the cluster, when a snapshot rule in one application server changes, the snapshot rules in other application servers also need to be changed in the same way. Therefore, in this embodiment, when a certain snapshot rule in an application server changes and another target application server in the cluster also uses the snapshot rule, the changed snapshot rule is synchronized to the target application server. Therefore, by adopting the method, the complicated operation that the user configures the snapshot rule one by one is avoided, and the overall efficiency is improved.
In addition, as a preferred embodiment, the snapshot rule specifically includes:
the specified monitoring content and corresponding monitoring information generated according to the monitoring content.
Wherein, the specified monitoring content comprises items such as CPU, GC, HTTP, JDBC, MEMORY and the like; the monitoring information includes a series of information helpful for the user to analyze the failure, such as GC log, MEMORY summary, MEMORY detailed information, JSTACK, etc. It should be noted that the monitored content can be obtained by reading the data interface provided by the application server, but a reasonable reading frequency should be maintained, and the overall performance of the application server may be affected by too high a reading frequency.

In addition, since a plurality of snapshot rules can be executed, a user can customize the corresponding snapshot rule according to needs and apply the corresponding snapshot rule to the application server snapshot service, so that the snapshot rule is not limited to the content provided by the snapshot service by default, and the customization degree of the snapshot rule is higher.
