Recently in the log analysis of this piece, to use Logstash+elasticsearch+kibana to implement log import, filtering and visual management, official documentation is not detailed enough, the online articles are mostly either for the use of Linux systems, or the copying of other people's configuration is mostly impossible to run. It took a lot of effort to get rid of these three things, write a usage experience, nonsense not much to say, into the subjec

People who have visited the factory assembly line must be familiar with the assembly line name. The semi-finished products flow through a series of assembly line nodes on the belt conveyor. Each node is further assembled in its own way and then transmitted to the next node. Modern High-Performance CPUs all adopt this pipeline design, which divides computing tasks into several stages, including finger fetch, decoding, execution, memory access, and feed

Pipelines can be used for communications between kinship-related processes. Famous pipelines overcome the restriction that pipelines do not have a name. Therefore, in addition to the functions of pipelines, it also allows communication between unrelated processes;
