1, Flume agent installation (using SPOOLDIR mode to obtain system, application and other log information)Note: Install with Jyapp userWhen a single virtual machine deploys multiple Java applications and needs to deploy multiple flume-agent for monitoring,The following configuration files need to be adjusted:The Spool_dir parameter in a flume-agent/conf/app.confJm

Flume as a log acquisition system, has a unique application and advantages, then flume in the actual application and practice in the end what is it? Let us embark on the Flume road together.1. what is Apache Flume(1) Apache Flume is simply a high-performance, distributed l

a common distributed log collection system:Apache Flume, Facebook Scribe,Apache chukwa 1.flume, as a real-time log collection system developed by Cloudera, has been recognized and widely used by the industry.

Chapter 2 mapreduce IntroductionAn ideal part size is usually the size of an HDFS block. The execution node of the map task and the storage node of the input data are the same node, and the hadoop performance is optimal (Data Locality optimization, avoid data transmission over the network ). Mapreduce Process summary: reads a row of data from a file, map function processing, Return key-value pairs; the system sorts the map results. If there are multi

Recently in a distributed call chain tracking system,Flume is used in two places, one is the host system, and the flume agent is used for log collection. One is to write HBase from Kafka log parsing.After this flume (from Kafka log analysis after writing flume) with 3 units, the system went online, after the online thr

Using Apache flume crawl data, how to crawl it? But before we get to the point, we have to be clear about what Apacheflume is.First, what is Apache FlumeApache Flume is a high-performance system for data acquisition, named after the original near real-time log data acquisition tool, which is now widely used for any stream event data acquisition and supports aggregating data from many data sources into HDFs.

Project requirements is the online server generated log information real-time import Kafka, using agent and collector layered transmission, app data passed through the thrift to agent,agent through Avro Sink to send the data to collector, Collector The data together and sends it to Kafka, the topology is as follows: The problems encountered during debugging and the resolution are documented as follows: 1, [Error-org.apache.thrift.server.abstractnonblockingserver$framebuffer.invoke (AbstractN

Target: Using flume agent implementation, the data in the Kafka is taken out and fed into elasticsearch. Analysis: Flume agent needs to work, two points: Flume Kafka Source: Responsible for reading from the Kafka data; Flume ElasticSearch Sink: Responsible for the data into the ElasticSearch; The current

Recently, an ELK architecture is used for log collection. the intermediate data collection is changed from logstash to flume. The following is the installation of flume: because flume and Elasticsearch are both developed in java, so the java is deployed before installation, ES does not support java1.7, because there is a major bug, so choose jdk-8u51-linux-x64.rp

Users can not only customize the source of the Flume, but also customize the flume sink, the user-defined sink in flume only need to inherit a base class: Abstractsink, and then implement the method in it, For example, my current requirement is that as long as the user uses my custom sink, then it needs to provide a file name, if there is a specific path, you nee
