Take a look at a summary from Daniel:Agent node monitoring all files under the log folder, each agent listens for up to 1024 files , each file in the agent will have a cursor-like thing, record the location of the liste
1. Introduction to Flume Flume is a distributed, reliable, andHigh AvailabilityA system that aggregates massive logs. It supports customization of various data senders to collect data. Flume also provides simple processing of data and writes it to various data receivers (customizable) capabilities.Design goals: (1) Reliability When a node fails, logs can be trans

listening, there is no file record, so the file will be re-read, so that the log will be duplicated, the specific recovery method is as followsThe log files that have been sent under the Listening log folder on the agent node are moved out and processed and the agent can be restarted after the failure.Note: In the case of failure of the agent node, according to the point of failure, the data files before the point in time are moved out, the Flume.age
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
Flume installation and configuration, and flume installation ConfigurationFlumeInstallation and configuration 0. Follow jdk. Download the jdk-1.8.0 and apache-flume Binary packagesSet the software path as follows:Jdk: // usr/local/jdk-1.8.0Flume:/opt/apache-flume 1. Configure flume
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
[Flume] uses Flume to pass the Web log to HDFs example:Create the directory where log is stored on HDFs:$ HDFs dfs-mkdir-p/test001/weblogsflumeSpecify the log input directory:$ sudo mkdir-p/flume/weblogsmiddleSettings allow log to be accessed by any user:$ sudo chmod a+w-r/flume$To set the configuration file contents:$
Flume + Solr + log4j build web Log collection system, flumesolr Preface Many web applications use ELK as the log collection system. Flume is used here because they are familiar with the Hadoop framework and Flume has many advantages. For details about Apache Hadoop Ecosystem, click here. The official Cloudera tutorial is based on this example. get-started-with-h
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
Is Flume a good fit for your problem?If you need to ingest textual log data into Hadoop/hdfs then Flume are the right fit for your problem, full stop. For other use cases, here is some guidelines:Flume is designed to transport and ingestregularly-generatedeventdataoverrelativelystable,potentiallycomplextopologies.

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,

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
