elk server

Elk is a powerful tool for log revenue and analysis.1, elasticsearch cluster constructionSlightly2. Logstash Log CollectionI am here to achieve the following 2 steps, in the middle with Redis queue buffer, can effectively avoid the ES pressure too large:1, n agent on the log of n services (1 to 1 of the way), from the log file parsing data, deposit broker, here is a Redis subscription mode message queue, of course, you can choose Kafka,redis more conv

First heard elk, is Sina's @argv introduction internal use elk situation and scene, at that time touched very big, originally have so convenient way to collect log and show, have such tool, you do bad thing, delete log, it has no effect.A lot of companies say they are concerned about security, but they have not seen and watched the logs of their servers, which is a bit ironic. Manage the logs first, and the

Logstash is an open-source server-side data processing pipeline. It can collect data from multiple sources, convert data, and send the data to your favorite "repository.

Therefore, make sure that jdk1.8 has been installed and configured on the machine before installation.1) follow the download t

In addition to the basic projects, elk also do related migrations .... Logstash say, the client only need to change the code logic Redis address on it, Logstash server directly docker pull mirroring on it. Elasticsearch need to write our own script migration, because the Cross engine room import export, very time-consuming, about the migration of Elasticsearch, I write the next chapter, today's main write K

Network-related Big data analysis architecture with Kafka + Spark + Hadoop better, or elk solution better. Regardless of machine learning, the main use of spark SQL and streaming to do timing processing and data aggregation query, found that elk can also complete the same function, elk is relatively lightweight, easier to deploy and maintain.

LK StackIn general:1, developers are unable to log on to the online server to view log information2, various systems log a wide range of log data scattered difficult to find3, the volume of log data is large, the query speed is slow, the data is not enough real time4, a call involves multiple systems, which makes it difficult to locate data quickly in these systems Elk Stack = Elastic Search + Logstash + K

Preface: 1. The deployed Elk Architecture is elasticsearch (hereinafter referred to as ES) +logstash+kibana+filebeat The 2.Filebeat deployment is responsible for collecting logs on the nodes that need to collect the logs. The Logstash and ES are then filtered for analysis, and then transferred and focused on the Kibana system for visual display. 3. Non-cluster deployment None-cluster 4. The elasticsearch,kibana are made up of 5.5.2→6.0.0, while Logst

I. Architecture at a glance: The so-called elk, respectively refers to the Elasticsearch, Logstash, Kibana; Official website: https://www.elastic.co/products; Three roles clear: Elasticsearch is responsible for indexing (create INDEX, search data), equivalent to the database; Logstash is responsible for uploading the log, in the process of uploading the log, the log can be structured, the regular log into the Elasticsearch Kibana is responsible for vi
