Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The embodiment of the invention provides a distributed monitoring method for the running state of a cloud access controller. Referring to fig. 1, the method includes the following steps:
step S1: the cloud access controller is provided with a plurality of monitoring processes, wherein one monitoring process is a current monitoring process, and the rest monitoring processes are backup monitoring processes.
In the embodiment of the invention, the cloud access controller is a distributed system consisting of a plurality of servers and a plurality of service modules.
The cloud access controller is provided with a plurality of monitoring processes, preferably, the number of the monitoring processes is three, and the monitoring processes are respectively deployed in three different servers. At the same time, only one monitoring process is operated as the current monitoring process, and other monitoring processes are used as backups.
Step S2: and establishing a root node for monitoring the current monitoring process in the distributed processing framework, and establishing a child node under the root node.
In this embodiment, the distributed processing framework is based on ZooKeeper, which is a distributed application program coordination service of an open source code, and can provide a consistency service for distributed applications, and is mainly used to solve the problem of data management in distributed applications, for example, the provided functions include: unified naming services, state synchronization services, cluster management, management of distributed application configuration items, and the like. In addition, the ZooKeeper can also provide data storage based on a directory node tree mode similar to a file system, and is mainly used for maintaining and monitoring state change of stored data. By monitoring these data state changes, data-based cluster management can be achieved.
A permanent node monitor is created in the ZooKeeper, and the permanent node monitor is used as a root node for monitoring the current monitoring process.
After the monitoring process is started, a temporary node/monitors/monitor-process ID-is created under the permanent node monitors, namely, a child node of the root node, and meanwhile, the child node is set as a sequence value self-increment node, and the ZooKeeper automatically adds a sequence value to the last of the name of the child node, for example, the sequence value of the child node in the root node is the sequence value of the previous child node plus 1.
Step S3: according to a preset rule, the distributed processing framework distributes monitoring authority to child nodes under a root node, and the child nodes with the monitoring authority monitor the current monitoring process.
In the embodiment of the present invention, the preset rule for allocating the monitoring right is:
acquiring sequence values of all child nodes under a root node, and judging whether the sequence value of the current child node is minimum in the sequence values of all the child nodes;
if so, the distributed processing framework allocates a monitoring authority to the current child node with the minimum sequence value, and the current child node starts a monitoring current process after acquiring the monitoring authority;
if not, setting a state monitoring callback in the previous child node by the current child node, for example, if the sequence value of the current child node is 2, setting the state monitoring callback on the child node with the sequence value of 1; judging whether the sequence value of the previous child node is the minimum in the sequence values of all the child nodes; until determining the child node with the minimum sequence value under the root node as the current child node; and the distributed processing framework allocates monitoring authority to the smallest child node in the sequence value, and the child node starts a monitoring current monitoring process after acquiring the monitoring authority.
Step S4: the current monitoring process monitors server performance data of a plurality of servers and/or service processing information of a plurality of service modules in the cloud access controller.
In an embodiment of the present invention, a service (Server) node is created under the root node, and a sub-node is created under the service node, where the sub-node includes a first sub-node and a second sub-node.
Specifically, after the server performance acquisition program is started, a temporary node, that is, a first sub-node of the service node, is created under the service node, and the cloud access controller writes server information into the first sub-node, so that the first sub-node monitors server performance data of the server, where the server information may include, but is not limited to: host name, performance indexes such as CPU, memory, disk, etc. After the service module is started, a temporary node, that is, a second sub-node of the service node, is created under the service node, and the cloud access controller writes service module information into the second sub-node, so that the second sub-node monitors service processing information of the service module, where the service module information may include, but is not limited to: host name, module name, traffic handling in time period, etc.
And the current monitoring process acquires server information and service module information for monitoring.
Specifically, after the monitoring process is started, all the sub-nodes under the service node are added into the cache and the states of all the sub-nodes are monitored. And if the state of the sub-node is changed, acquiring all the sub-nodes under the service node. Comparing all sub-nodes under the acquired service node with all sub-nodes in the cache, if the sub-nodes in the cache do not exist in the acquired sub-nodes, the monitoring process considers that the non-existing sub-nodes are abnormal, and the monitoring process sends an abnormal message to the cloud access controller; and if the subnode in the cache exists in the acquired subnode, the monitoring process acquires the server performance data and/or the service processing information in the subnode and sends the server performance data and/or the service processing information to the cloud access controller for processing.
Step S5: if the current monitoring process is abnormal, the distributed processing framework deletes the child node monitoring the current monitoring process, determines a new current monitoring process from the backup monitoring process, and determines a new child node from all child nodes under the root node to monitor the new current monitoring process.
In the embodiment of the present invention, by monitoring the child nodes of the current monitoring process, the current monitoring process performs information interaction with the root node, such as server performance data and/or service processing information. In addition, the distributed processing framework presets a time interval, for example, 5 minutes, according to which the current monitoring process periodically sends server performance data and/or traffic processing information to the root node.
If the root node does not receive the information sent by the current monitoring process within the time interval, namely the monitoring process terminates the information interaction with the root node, the distributed processing framework deletes the child node monitoring the current monitoring process and sends the node deletion information to the child node of the next sequence value.
Because the child node sets a state monitoring callback in the previous child node, when the child node of the next sequence value receives the node deletion information of the previous child node, the current monitoring process is considered to be abnormal, and a new monitoring process is selected from other backup monitoring processes through an algorithm to take over the operation. The specific algorithm for selecting a new monitoring process from the backup monitoring processes to take over the operation is not limited in the embodiment of the present invention.
In addition, the distributed processing framework acquires the sequence values of all the child nodes under the root node again, and determines the child node with the minimum sequence value as a new child node to monitor a new current monitoring process according to the preset rule.

after the current monitoring process is started, all sub-nodes under the service node are added into the cache and the states of all the sub-nodes are monitored, when the states of the sub-nodes are changed, all the sub-nodes under the service node are obtained, and all the obtained sub-nodes are compared with all the sub-nodes in the cache;
if the sub-node in the cache does not exist in the acquired sub-node, the current monitoring process judges that the non-existing sub-node is abnormal and sends abnormal information to the cloud access controller;
and if the subnode in the cache exists in the acquired subnode, the current monitoring process acquires the server performance data and/or the service processing information monitored by the existing subnode and sends the server performance data and/or the service processing information to the cloud access controller for processing.
9. The system for distributed monitoring of the operating state of the cloud access controller according to claim 8, wherein the occurrence of an abnormality in the current monitoring process specifically includes:
the current monitoring process periodically sends server performance data and/or service processing information according to a preset time interval;
and if the server performance data and/or the service processing information sent by the current monitoring process are not received in the time interval, the current monitoring process is abnormal.
10. The system for distributed monitoring of the operating state of a cloud access controller according to claim 9, wherein the distributed processing framework is further specifically configured to:
if the current monitoring process is abnormal, the distributed processing framework deletes the child node monitoring the current monitoring process and sends node deletion information to the child node of the next sequence value; when the child node of the next sequence value receives the node deletion information, the abnormal information of the current monitoring process and the child node monitoring the current monitoring process is sent to the root node, and then the distributed processing framework determines a new current monitoring process from the backup monitoring process and determines a new child node from all child nodes under the root node to monitor the new current monitoring process according to the preset rule.
