Logs are an important way to analyze online problems, usually we will output the logs to the console or local files, to troubleshoot the problem by searching the local log according to the keyword, but more and more companies, project development with a distributed architecture, logs are recorded in multiple servers or files, When you analyze a problem, you may need to view multiple log files to locate the problem, and if the related project is not a team maintenance, the communication cost incr
ELK + filebeat log analysis system deployment document
Environment DescriptionArchitecture Description and architecture Diagram
Filebeat is deployed on the client to collect logs and send the collected logs to logstash.Logstash sends the collected logs to elasticsearch.Kibana extracts and displays data from elasticsearch.The reason why filebeat is used for log collection is that filebeat does not use a large amount of resources like logstash, affecting the Service server.

But the collection and processing of slow queries also cost us too much time and effort, how can we improve efficiency in this piece? and see how this article explains how to use elk to do slow log collection

1. Overview
In a distributed cluster environment, the log content of a single node tends to be stored on its own node, which has many problems. We need a unified log processing center to collect and centrally store logs, and to view and analyze them. The Twelve-factor app has recommendations for log processing.
The corresponding processing technology is now very mature, usually using elastic Search + logstash + Kibana technology Stack (ELK). In this a
These three functions are log collection, index and search, and visualized display.
L logstash
This architecture diagram shows that logstash is only the place where collect and index are located. A. conf file is input during runtime, And the configuration is divided into three parts: input, filter, and output.
L redis
Redis serves as a decoupling between log collection and indexing.
L elasticsearch

First, IntroductionHeapster is a cluster-wide monitoring and event data aggregator. It natively supports kubernetes and can be run on all kubernetes settings. Heapster is run as a cluster in a group, similar to how any other kubernetes application runs. InfluxDB is an open source database written in go that is designed to handle time-series data with high availability and high performance requirements. It exposes an easy-to-use API to write and get time series data. The Heapster is
