The collection of user behavior data is undoubtedly a prerequisite for building a referral system, and the Flume project under the Apache Foundation is tailored for distributed log collection, this is the 1th of the Flume research note, which mainly introduces Flume's basic architecture, The next note will illustrate the deployment and use steps of flume with an

In flume1.5.2, if you want to get flume related metrics through HTTP monitoring, add the following after the startup script:-dflume.monitoring.type=http-dflume.monitoring.port=34545MonitoringThe-D attribute can be obtained directly through system.getproerties (), so the above two properties are read by Method Loadmonitoring (), and the method is flume in the portal application private void Loadmonitoring ()
One, what is flume?As a real-time log collection system developed by Cloudera, Flume is recognized and widely used by the industry. The initial release version of Flume is currently known collectively as Flume OG (original Generation), which belongs to Cloudera. However, with the expansion of the

Apache Flume is a distributed, reliable, and efficient system that collects, aggregates, and moves data from disparate sources to a centralized data storage center. Apache Flume is not just used in log collection. Because data sources can be customized,flume can use the transfer of a large number of custom event data, including but not limited to website traffic

There are many examples of failover on the Internet, but there are multiple approaches, and individuals feel that the principle of single responsibility1, a machine running a flume agent2, a agent downstream sink point to a flume agent, do not have a flume agent configuration multiple Ports "impact performance"3, sub-machine configuration, you can avoid a driver,
Analysis of various encryption technologies and code samples in PHP, and php encryption code samples Symmetric encryption (also called private key encryption) refers to the encryption algorithm that uses the same key for encryption and decryption. It is also called the traditional cryptographic algorithm, that is, the encryption key can be derived from the decryption key, and the decryption key can also be
First, IntroductionRecently in the study of Big data analysis related work, for which the use of the collection part used to Flume, deliberately spent a little time to understand the flume work principle and working mechanism. A personal understanding of a new system first, after a rough understanding of its rationale, and then from the source code to understand some of its key implementation part, and fina
Flume ng Overview:Flume Ng is a distributed, highly available, reliable system that collects, moves, and stores disparate amounts of data into a single data storage system. Lightweight, simple to configure, suitable for a variety of log collections, and supports failover and load balancing. Where the agent contains Source,channel and Sink, three have formed an agent. The duties of the three are as follows: Source: Used to consume (collect) th

I haven't written a blog for a long time. We have recently studied storm, flume, and Kafka. Today, I will write down the scenarios and conclusions for testing flume failover and load balance; The test environment contains five configuration files, that is, five agents. A main configuration file, that is, the configuration file (flume-sink.properties) for configur
I. Introduction of FlumeFlume is a distributed, reliable, and highly available mass-log aggregation system that enables the customization of various data senders in the system for data collection, while Flume provides the ability to simply process the data and write to various data-receiving parties (customizable).Design goal:(1) ReliabilityWhen a node fails, the log can be transmitted to other nodes without loss.

The method of random disturbance of training samples in matlab, matlab Samples Use randperm () to generate random seeds, and then swap locations for random sample extraction. Official content: The built-in function randperm (n) of Matlab generates random orders of integers ranging from 1 to n without duplicates. Then, we can use it to obtain random numbers without duplicates.Function p = randperm (n );% RAN
