Description
Technical Field
The present invention relates to the field of data acquisition, and more particularly, to a distributed data acquisition method and apparatus for a complex network.
Background
The current collector of a complex network has two functions: firstly, acquiring out-of-band and in-band information of infrastructure and reporting the information to a complex network; and the other is used as a load balancer. If there are several collectors in the current network, these collectors will share the devices. If the service of the collector is abnormal, the complex network can automatically bind the resources bound on the collector to other collectors.
In the prior art, the resources are bound randomly or by a collector with lower load. For a complex network, the collector is IO (input/output) intensive rather than computation intensive, so the requirement on the system load is less than that on IO. The problem of the prior art is that the method is insensitive to the network environment, and the network levels of other collectors cannot be sensed among the collectors, so that the distribution of the collection tasks cannot be adjusted according to the network topology.
Aiming at the problem that the collector in the prior art cannot adjust the distribution of the collection tasks according to the network topology, no effective solution is available at present.

It will be understood by those skilled in the art that all or part of the processes of the methods of the embodiments described above can be implemented by a computer program, which can be stored in a computer-readable storage medium, and when executed, can include the processes of the embodiments of the methods described above. The storage medium may be a magnetic disk, an optical disk, a read-only memory (ROM), a Random Access Memory (RAM), or the like.

In some embodiments, each collector is connected to multiple infrastructures; the collection task is performed to collect and export in-band and out-of-band data information from the infrastructure, including servers, storage devices, network devices, and firewalls, to a network level above.

In some embodiments, determining that the first collector is offline comprises:
continuously monitoring a heartbeat signal of the first collector, and detecting the connectivity of the first collector in response to the stop of the heartbeat signal of the first collector;

The following further illustrates embodiments of the invention in terms of specific examples.
Firstly, traversing all collectors and all switches in the complex network to generate configuration files, and generating and storing a tree topology structure according to the configuration files, wherein the network hierarchy structure can be as shown in fig. 2: tux0-15 is a collector, s0-3 is a switch at the upper layer, and s4-7 is a switch at the higher layer.
The embodiment of the invention monitors the heartbeat of the collector in real time, and triggers the ping task when the heartbeat stops. When ping is not connected for three times, the collector is considered to be offline, and the resources bound to the offline collector are released. Tux8 offline, for example, embodiments of the present invention traverse to find the collector closest to tux 8. Consider first the other collectors tux9-11 at the same network level, picking tux10, which is more recent than tux8, to perform tux8 collection tasks and allocate resources if tux10, 11 are available. If tux10-12 is not available, then a sibling collector is determined: the network layer of switch s2 first looks for a nearest switch at tux8, e.g., s3, and then determines a nearest collector, e.g., tux15, among the collectors tux12-15 of s3, performs tux8 acquisition tasks and allocates resources.
In addition, if a plurality of links which are as close as each other exist at the same time when comparing distances, the link with the maximum transmission speed can be selected to increase the transmission speed. The collector is IO intensive rather than calculation intensive, so the requirement on the system load is less than the requirement on IO, and the requirement on the transmission speed should be met preferentially.
