Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Examples
The embodiment of the invention discloses a large-scale equipment heartbeat management method suitable for an optical fiber matrix KVM, and the specific implementation flow of the management method is shown in FIG. 1, and mainly comprises steps 101 to 103, wherein the steps are as follows:
step 101: and controlling a switching board card preset in the optical fiber matrix KVM to receive a first heartbeat signal sent by each of a plurality of devices connected with the switching board card.
In this embodiment, this step is: and controlling the exchange board card to receive and store a first heartbeat signal sent by each device connected with the exchange board card according to the time interval of two adjacent heartbeat times of the exchange board card.
Specifically, in this embodiment, the device heartbeat signal report based on the optical moment KVM system is transmitted to the KVM control host through the switch board card, so that it is known that the switch board card is an intermediate transmission medium for uploading the heartbeat signal to the host by the device, so as to solve the problem that the KVM control host frequently receives responses of continuous running state changes caused by respective heartbeat signal reports of the TX/RX box and the switch card, and therefore, heartbeat notification is performed by taking the switch board card as a unit, that is, the switch board card uniformly receives heartbeat signals reported by the RX/TX box connected to the switch board card, and in particular, in order to avoid separate uploading of the heartbeat signals of the switch board card and the device, the heartbeat signals of the TX/RX box received between two heartbeat times of the switch board card can be received.
In this embodiment, in the time interval between two adjacent heartbeat times of the switch board card, the first heartbeat signal is received by the switch board card, so that the heartbeat signal of the device and the heartbeat signal of the switch board card are sent to the KVM control host together, occupation of the transmission resource and increase of the processing times of the KVM control host caused by separate uploading of the device and the board card are avoided, and occupation of the transmission resource and decrease of the processing times of the KVM control host are reduced.
Step 102: integrating the first heartbeat signal sent by each device and the heartbeat signal of the switching board card to obtain an integrated heartbeat signal, and sending the integrated heartbeat signal to a KVM control host in the optical fiber matrix KVM through the switching board card.
In this embodiment, the steps include: integrating a plurality of first heartbeat signals stored in the exchange board card and the heartbeat signals of the exchange board card into a json signal, and adding a non-form field array in a json command corresponding to the json signal; and recording the equipment ID of each equipment transmitting the first heartbeat signal to the exchange board card through the non-identity field array.
Specifically, in this embodiment, after the switch board card receives the heartbeat signals reported by the RX/TX box connected to the switch board card, the heartbeat signals are combined to form a heartbeat signal of the switch card device, and then the heartbeat signal is reported to the KVM control host, referring to fig. 3, when the heartbeat signals before being improved are uploaded, the heartbeat signals of the device and the switch board card are respectively and independently uploaded to the host control card, so that the host control card needs to respond once when each heartbeat signal is uploaded, and after being improved, the heartbeat signals of the TX box and the RX box are stored in the switch board card, and only the heartbeat signal of the device is uploaded once by the switch board card, so that occupation of the switch card to the cmd-rs485 transmission bus resource is reduced, and the number of times of processing cmd-rs485 serial port data by the KVM control master control is reduced.
Specifically, a plurality of heartbeat json signals stored by the switch board card, namely heartbeat signals of equipment, and the heartbeat signals of the switch board card are integrated into a heartbeat json signal, a notify field array is added in a json command, and equipment IDs of reported heartbeat signals of an RX/TX box received in the interval of two heartbeats of the switch board card are recorded in the array.
In this embodiment, the step reduces the number of transmissions by integrating the heartbeat signal, reduces the occupation of transmission resources and the number of processing times of the KVM host, and integrates the signals into a single json signal when integrating the signals, so that a notify field array is added in the json command corresponding to the json signal, and is used for recording the device ID of each device corresponding to the currently integrated heartbeat signal, so that the device ID is convenient to manage the devices subsequently.
Step 103: according to the integrated heartbeat signal, the KVM control host is controlled to update the equipment state information of each piece of equipment to a preset database through a preset data caching strategy, meanwhile, the KVM control host is used for carrying out function configuration on each piece of equipment, and each end of the optical fiber matrix KVM is notified asynchronously with a transmission bus through a preset interface to change the equipment state of each piece of equipment according to the function configuration.
In this embodiment, the steps include: according to the database field modified in advance, the KVM control host is controlled to read preset cache data, and whether first equipment state information to be updated exists in the cache data is judged according to the equipment ID recorded in the integrated heartbeat signal; if the first equipment state information to be updated exists in the cache data, updating the first equipment state information through the KVM control host according to the integrated heartbeat signal, and caching second equipment state information obtained after updating to the cache data; if the first equipment state information to be updated does not exist in the cache data, the first equipment state information to be updated is read from the database according to the equipment ID, the first equipment state information is updated through the KVM control host according to the integrated heartbeat signal, and the second equipment state information obtained after updating is cached to the cache data; and updating the equipment state information of each piece of equipment to the database according to a preset updating time point and the cache data.
Meanwhile, analyzing the integrated heartbeat signal through the KVM control host to obtain first heartbeat signals respectively sent by each device, and respectively carrying out functional configuration on each device according to the first heartbeat signals; according to the functional configuration, asynchronously notifying each end of the optical fiber matrix KVM through a preset rpc interface and a cmd-RS-485 transmission bus to change the equipment state of each piece of equipment; each end comprises a client, a web end and a server.
Specifically, in this embodiment, after the integrated device heartbeat signal is uniformly reported to the KVM control host by the switch board, the KVM control host updates the device status information to the database of the KVM control host after receiving the reported command signal, further, referring to fig. 4, after receiving the heartbeat command signal reported by the device, the KVM control host in the original optical matrix KVM system directly operates the database according to the information in the heartbeat command signal, and writes the heartbeat command signal into the database, however, frequent read-write operation on the database may cause that the resource occupation of the KVM control host is higher and the operation time is longer, resulting in the reduction of the efficiency of the control host.
In order to reduce frequent operation of the database, a database caching strategy is preset, and the existing database fields are optimized, namely, the fields of equipment up-down line and equipment heartbeat time in the database are removed, and the fields are modified to be recorded into a cache, and referring to fig. 4, the KVM control host can directly read preset cache data according to the optimized fields after receiving a heartbeat command signal, so that consumption caused by frequent database operation is reduced, direct database operation is reduced through the caching strategy, and data acquisition efficiency is improved.
When the KVM control host reads preset cache data, if the read data hits the cache, the data is directly returned, if the read data does not hit the cache, the data is read from the database, then the data is written into the cache and returned to a user, then the hit cache data is updated according to a heartbeat command signal, after a certain period of time, when the preset database updating time point is reached, the database is updated according to the data content in the cache data, and when the database is updated, the data in the database is updated first, and then the data in the cache is deleted.
Further, when the KVM control host updates the database, the KVM control host performs functional configuration on the device uploading the heartbeat signal according to the heartbeat command signal, and after performing functional configuration, the KVM control host notifies each end of the KVM control host that the device state is changed after each command operation response, including a client, a web, a server, etc., according to fig. 5, after performing functional configuration, the KVM control host frequently notifies each end of the operation occupation and efficiency reduction, and after improving the prior art, the embodiment provided in this embodiment asynchronously notifies each end of the device state change through rpc interface and cmd-RS-485 transmission bus according to fig. 5, thereby reducing the number of times of service notification and optimizing time consumption due to notification; and the notification service uses an asynchronous notification mode, so that the processing of the next data in the queue can be quickened.
In this embodiment, in order to reduce frequent operations on the database, add a database caching policy and optimize the existing database field, and utilize preset cache data to reduce consumption caused by frequent database operations, and simultaneously reduce operations of a direct database through the caching policy, improve data acquisition efficiency and response speed, and simultaneously perform functional configuration of multiple devices based on an integrated heartbeat signal, so that notification times of services can be reduced, time consumption caused by notification is optimized, and simultaneously notification of services in an asynchronous notification manner is used, so that processing of next data in a queue can be accelerated, and response speed of the fiber matrix KVM is further improved.
