Introducing ELK StackĮLK is a collection of three open-source applications - Elasticsearch, Logstash, and Kibana from Elastic that accepts data from any source or format, on which you can then perform search, analysis, and visualize that data. In this article, you will also tackle this problem and learn how you can view the logs of multiple services separately that are running in parallel inside one single application. This article will demonstrate how you can integrate ELK Stack with a Spring Boot application to collect, process, store, and view the logs.Īpart from this, while working with the ELK stack, the default action is to show all the logs of a particular application at a single place inside Kibana. As a solution for this problem, we're going to look at the ELK stack, a useful tool for centralized log aggregation and analysis. They can help sysadmins, support teams, and even developers to follow the different operations carried out by the different services of the system.īut it becomes very complex to maintain this critical data in a distributed environment where many applications, services, and systems are running.

This is where Logs act as essential information that allows us to investigate better and diagnose the errors. For instance, in a microservices architecture, any single operation triggers a chain of API calls making it challenging to debug the entire application in case an error comes. Having a good log monitoring infrastructure is a key feature to have while developing any software.

The application's source code used in this tutorial is available in this GitHub repository.

You will also learn how to create custom index patterns through a Filebeat configuration and separate logs of different services of the same application by different indexes.

This article will demonstrate how to integrate ELK Stack with a Spring Boot application for logs aggregation and monitoring in a centralized and scalable way. They can help us follow the different operations carried out by the various services of our system. system.TL DR: Logs are the most critical way for debugging. The index/alias name is the value of the field 'log_type', e.g. The following will send the json log line to elasticsearch. Match => ', 'MMM d HH:mm:ss', 'MMM dd HH:mm:ss' ]įinally, the output - under /etc/logstash/conf.d/nf The same can be done for other logs, like nginx, mysql, apache2, etc. In this setup I am demonstrating how to handle the system logs (syslog and auth It provides a user interfaceįor searching and displaying data from indices and managing them. Kibana is basically the GUI of Elasticsearch. It can convert the log files into a differentįormat, it can add and remove fields, etc.Įlasticsearch is a very famous search engine, based on Lucene. Logstash is a tool for beautifying the logs. Most commonly used, Kafka and many others are also supported.

Here I am demonstrating a possibleįirst, some words about each of them, in case you don't know them:įilebeat is a tool, that watches for file system changes and uploads the file contents to a destination (output). However, configuring them can be difficult. Way to access, search and view multiple log files is the combination ofįilebeat, Logstash, Elasticsearch and Kibana. An important part of this are the log files.
