kafka log aggregation

1. Background introduction Many of the company's platforms generate a large number of logs per day (typically streaming data, for example, the search engine PV, query, etc.), the processing of these logs requires a specific log system, in general, these systems need to have the following characteristics: (1) The construction of application systems and analysis systems of the bridge, and the correlation between them decoupling (2) support for near real

an absolute offset of 7: The first is to use a binary lookup to determine which logsegment it is in, naturally in the first segment. Open the index file for this segment, and also use binary lookup to find the largest offset in the index entry with offset less than or equal to the specified offset. The index of natural offset 6 is what we're looking for, and we know from the index file that the message with offset 6 has a position of 9807 in the data file. Open the data file an

-round. 3 Implementing the Architecture A schema implementation architecture is shown in the following figure: Analysis of 3.1 producer layer The service assumptions within the PAAs platform are deployed within the Docker container, so in order to meet the non-functional requirements, another process is responsible for collecting logs and therefore does not invade the service framework and processes. Using flume ng for log collection, this open s

Log aggregation is the log centralized management feature provided by yarn that uploads the completed container/task log to HDFs, reducing the nodemanager load and providing a centralized storage and analysis mechanism. By default, the container/task log exists on each NodeM

Log storage parsing for Kafkatags (space delimited): KafkaIntroductionThe message in Kafka is organized in topic as the basic unit, and the different topic are independent of each other. Each topic can be divided into several different partition (each topic has several partition specified when the topic is created), and each partition stores part of the message. By borrowing an official picture, you can vis

the tasks are set to being the same as the number of executors, i.e. Storm would run one task per thread.both spout and bolts are initialized by each thread (you can print the log, or observe the breakpoint). The prepare method of the bolt, or the open method of the spout method, is invoked with the instantiation, which you can think of as a special constructor. Every instance of each bolt in a multithreaded environment can be executed by different m
