Embodiment 1

[0039] like figure 1 shown.

[0040] A fog cluster management system based on nagios monitoring includes a cloud server and a fog cluster; the fog cluster includes fog control nodes and fog nodes; and the fog nodes are connected in the same local area network. When the fog node sends a network request, it must be forwarded by the fog control node. The cloud server is provided by a cloud center vendor. The fog control nodes are high-performance server groups.

[0041] The fog nodes are heterogeneous devices at the edge of the network; the fog nodes are switches, routers and idle PCs.

Embodiment 2

[0043] like Figure 2-4 shown.

[0044]A fog cluster management method based on nagios monitoring, implemented based on the fog cluster management system of embodiment 1, comprising the following steps:

[0045] 1) Initialize the environment; install the Nagios application in the fog control node to detect the fog node status and service status in the fog cluster; the fog control node installs a mysql database, and establishes corresponding information respectively for the fog nodes and computing service types in the fog cluster node table and computing service table;

[0046] The node table includes: fog node ip address, ssh account number, ssh password, fog node load size, fog node memory total capacity, fog node memory remaining capacity, fog node hard disk total capacity, fog node hard disk remaining capacity, fog node and fog node The network delay of the control node, the name of the computing service installed on the fog node, and whether the fog node and the fog cont...

Embodiment 3

[0060] As in the fog cluster management method based on nagios monitoring described in embodiment 2, further, in the step 3), a node table record of the node is added in the node table while the fog node is detected; the increased node table record includes All field values ​​in the node table.

Abstract

The invention relates to a fog cluster management system and method based on nagios monitoring. According to the method provided by the invention, division is performed according to an area where fognodes are located, each area is composed of various fog nodes, and the fog node sin one area are uniformly managed by a fog control node that accesses a backbone core network; all users or IOT devicesin the area connect a request in the cloud and are finally connected to the backbone core network through the fog control node no matter being connected to a local area network or a wireless network,and the decision made through the fog control node to determine whether to forward the request to a cloud center or a fog cluster. The fog cluster management system and method based on nagios monitoring provided by the invention ensures more reliable and efficient service management through a nagios monitoring node and a service state in view of the characteristic that the heterogeneous load of the nodes in the fog calculation is uncertain.

Description

technical field [0001] The invention relates to a fog cluster management system and method based on nagios monitoring, and belongs to the technical field of fog computing. Background technique [0002] With the continuous development of 5G technology and Internet of Things technology, the global demand for connected devices is also growing exponentially. Fog computing not only increases the overall processing capacity by extending cloud computing to a location close to the user terminal, but also places part of the computing around the user, thereby reducing the pressure on the core backbone network and cloud center, which will surely become a future development trend. By deploying some computing services in the fog cluster to process some user requests, it can not only reduce the user request delay, but also reduce the cloud center load. Therefore, fog computing is not intended to replace cloud computing, but a supplement to cloud computing. Its main purpose is to meet th...
