Detailed Description
The core of the invention is to provide an agent control system for storage management software, which can save resources used by agents in the storage management software and reduce maintenance cost.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the invention. The invention is therefore not limited to the specific implementations disclosed below.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a logic structure of an agent control system for storage management software according to an embodiment of the present invention.
One embodiment of the present invention provides an agent control system for storage management software, including: the framework SA is arranged on each storage node and is used for being interconnected with the service module on the storage node; the plug-in part is arranged on each storage node and comprises n plug-ins, n is an integer not less than 1, the plug-ins on the same storage node correspond to the service modules one by one, and each plug-in comprises a corresponding agent; and the link function module is arranged on the main storage node and used for controlling each plug-in to execute each link action according to the state machine mechanism.
In the present embodiment, the frame SA preferably includes: the first judging unit is used for judging whether a plug-in corresponding to an external server of a service request of a service module on the storage node of the first judging unit is positioned in the storage node of the first judging unit; the plug-in calling unit is used for calling the plug-in to interact with the external server when the first judging unit judges that the plug-in corresponding to the external server of the service request of the service module on the storage node of the first judging unit is positioned in the storage node of the first judging unit; and the message forwarding unit is used for forwarding the message to the plug-in calling unit in the framework SA in the corresponding target storage node when the first judging unit judges that the plug-in corresponding to the external server of the service request of the service module on the storage node is not positioned in the storage node where the first judging unit is positioned.
As shown in fig. 1, the logic of the agent control system for storing management software including three nodes and two external servers is described as an example. In this system, each column is a storage node. The first storage node 1, the second storage node 2 and the third storage node 3 each comprise a framework SA, a plug-in a and a plug-in B. When the service module B in the third storage node 3 requests the server B, the service module B sends a service message to the framework SA of the third storage node 3, and the framework SA determines that the link is on the same storage node (node 3), and directly calls the plug-in B of the third storage node 3 to interact with the server B, thereby completing the interaction between the service module B and the server B. When the service request object of the service module a of the first storage node 1 is the server a, the plug-in a corresponding to the server a is located in the second storage node 2, at this time, the service module a sends a service message to the framework SA of the first storage node 1, the framework SA judges that the link node is not located in the node (the first storage node 1), the service message is forwarded to the link node (the second storage node 2), then the framework SA in the second storage node 2 calls the plug-in a corresponding to the server a in the second storage node 2 to interact with the server a, the message returned by the server a is returned to the framework SA of the first storage node 1, and the framework SA of the first storage node 1 receives the returned message and then forwards the returned message to the service module a of the first storage node 1.
In the embodiment, each agent is introduced into the system in a plug-in mode, and the link function module of the main storage node is adopted to uniformly complete the link action of each plug-in by a state machine mechanism, so that the redundancy of the original agent management mechanism is broken, the agents are uniformly managed, the code redundancy managed by each agent is fundamentally solved, the resources used by the agents are saved, and the maintenance cost is reduced.
It should be noted that, in this embodiment, the link function module on the main storage node may be integrated in the framework SA on the main storage node.
It should be further noted that, in this embodiment, one storage node is selected from all storage nodes in the storage management software as a master storage node, and the remaining storage nodes are used as slave storage nodes, and a link function module is provided in the master storage node to integrate the same management flow function of each agent into one node.
It should also be noted that the system preferably deploys the framework SA indifferently in binary form on the respective storage nodes and is always running.
Referring to fig. 2 and fig. 3, fig. 2 is a flow chart illustrating operation of a state machine of a main storage node according to an embodiment of the present invention; fig. 3 is a timing diagram for link establishment according to an embodiment of the present invention.
In one embodiment of the present invention, the link function module includes: the link information reading unit is used for reading the plug-in information of each plug-in and the server information of the corresponding external server after the main storage node enters the initial state; and the link establishing unit is used for controlling the main storage node and each auxiliary storage node to establish a link.
Further, the link establishing unit includes: the link establishment message sending subunit is used for sequentially sending link establishment messages to each storage node and controlling each storage node to call the interface of the corresponding plug-in to establish a link; the first judging subunit is used for judging whether the link establishment of the current storage node is successful or not, sending a link establishment success signal to control the link establishment message sending subunit to send the link establishment message to the next storage node when judging that the link establishment of the current storage node is successful, and sending a link disconnection signal when judging that the link establishment of the current storage node is failed.
Further, the link function module further includes: and the link testing unit is used for testing each link every other at a first preset time interval, judging whether each link is connected or not, testing again if the link is not connected, and sending a link disconnection signal when the two tests are not successful.
And the link reconstruction unit is used for traversing all the storage nodes at intervals of a second preset time interval to establish links when receiving the link disconnection signal.
And the link alarm unit is used for reporting the alarm that the link corresponding to the service is not communicated when the configuration of the external server of the plug-in corresponding to the current service exists and the connection is disconnected.
In this embodiment, as shown in fig. 2, the link function module on the main storage node controls each plug-in to perform each link action according to the state machine mechanism. Namely, the system supports the main storage node to realize the link functions of reading link information, link establishment, link maintenance, link disconnection and the like in the form of a state machine, and the rest storage nodes enter the circular waiting mode so as to receive the message of the main storage node. The main storage node enters an initial state, i.e., "initial" in fig. 2, and its link information reading unit reads the plug-in information of each plug-in and the server information of the external server, e.g., IP, port, certificate, etc., thereby completing reading of the link information and entering a link establishment state, i.e., "link establishment" in fig. 2. When the main storage node enters the link establishment state, as shown in fig. 3, fig. 3 illustrates an example in which 3 storage nodes are included. And sequentially sending messages to all nodes from the node 0, wherein all storage nodes are numbered according to a preset sequence, the node 0 is a main storage node, after receiving the messages, each node starts to call an interface provided by a plug-in of the node to start to establish a link, if the link establishment is successful, a main storage node link establishment success signal is returned, namely the normal state in the figure 2, if the link establishment is unsuccessful, the link establishment of the next storage node is started until the link establishment is successful or failed, if the link establishment is successful, a link testing state is carried out, and if the link establishment is failed, the link disconnection state is entered, namely the disconnection in the figure 2. The node 0 firstly sends a message to itself to start establishing a link, after the link is established successfully or fails, the node 0 sends a message to the node 1 to start establishing the link, and after the link is established successfully or fails, the node 0 sends a message to the node 2 to start establishing the link. When the current link is in the link instance state, the link instance unit of the main storage node instance measures the link once every first preset time interval, for example, measures the link once every 15 seconds, judges whether the link is connected, if the link is connected, the loop continues to loop, that is, the loop instance in fig. 2, if the link is not connected, the instance can be measured again, and if the link is not connected for two instances and the test is not successful, the link is in the link disconnection state, that is, the instance in fig. 2 fails to be in the disconnection state. When the current link is in a link disconnection state, the link reestablishing unit of the main storage node attempts to traverse and establish links from all the storage nodes at a second preset time interval, such as every 30 seconds, so as to prevent automatic recovery after network flash or network interruption.
Because the link function module also comprises a link alarm unit, if the configuration of the external server of the plug-in exists and the plug-in cannot be connected, the alarm that the link is not communicated is reported, and a user is provided to maintain the link, thereby improving the usability. The alarm may be automatically recovered if the user repairs the link.
In an embodiment of the present invention, each framework SA is provided with an encryption unit, configured to encrypt the interconnected messages when a storage node where the current service is located is different from a storage node where a plug-in corresponding to the requested external server is located.
And each framework SA is provided with a decryption unit for decrypting the encrypted feedback interconnected message when the storage node where the current service is located is different from the storage node where the plug-in corresponding to the requested external server is located.
Sometimes, the storage node corresponding to the external server and the link connection node are not in the same node, for example, the external server corresponding to the service module a of the first storage node shown in fig. 1 is the server a corresponding to the plug-in a of the second storage node. At this time, a message forwarding function is required, and the message is encrypted by the encryption unit, for example, the AES256 is used for encrypting the message, so as to ensure the security of the message, when the external server returns the message, the message may also be encrypted by the encryption unit of the storage node corresponding to the server, and the decryption unit of the storage node corresponding to the service module may decrypt the encrypted message and return the decrypted message to the service module.
In summary, in the agent control system for storage management software provided by the present invention, each agent is integrated into the management framework SA in the form of a plug-in, and the framework SA of the main storage node performs link test, alarm and reconnection when the link is disconnected, so that the problems of code redundancy and resource waste caused by the respective management of each agent are fundamentally solved, the release of manpower is realized, and the development cost is saved.
The above description details an agent control system for storage management software according to the present invention. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
