The ELK Stack (Elasticsearch, Logstash, Kibana) is a powerful log management and analytics platform. Elasticsearch stores and indexes logs, Logstash collects and transforms them, and Kibana provides visualisation dashboards. This guide installs the ELK stack on Ubuntu 26.04 LTS. Tested and valid on: Ubuntu 26.04 LTS Prerequisites Ubuntu 26.04 LTS with at least 4 GB […]
Learn to configure Logstash on cloud servers for Nginx logs, enhancing website management with Managed OpenSearch – a step-by-step guide
In this guide, you will configure a component of the systemd suite of tools to relay log messages from client systems to a centralized log collection server. You will configure the server and client to use TLS certificates to encrypt the log messages as they are transmitted across insecure networks such as the internet and also to authenticate each other.
In this tutorial, we will show you how to use Topbeat, on an Ubuntu 14.04 server, with an ELK stack to gather and visualize infrastructure metrics. Topbeat, which is one of the several “Beats” data shippers that helps send various types of server data to an Elasticsearch instance, allows you to gather information about the CPU, memory, and process activity on your servers.
In this tutorial we will show you how to install and configure Graphite – a tool for storing numeric time-series data and rendering graphs of this data. It consists of three software components:
L’un des avantages les plus éloquents de systemd est la journalisation des processus et des systèmes. Lorsqu’on utilise d’autres systèmes,les journaux se retrouvent généralement dispersés dans le système, traités par différents daemons et outils et parfois assez difficiles à interpréter lorsqu’ils s’étendent…
In this tutorial, you will learn how to configure your App Platform application to sed logs to a the cloud provider managed OpenSearch dashboard.
In this guide, we will look at how to utilize Nginx’s logging module. We’ll set up separate log files for different server blocks and then customize the logging output. We’ll also add additional information about requests (in this tutorial’s example, the time it takes to serve a request) to the access log beyond what Nginx includes by default.
Rsyslog, Elasticsearch, and Logstash provide the tools to transmit, transform, and store your log data. In this tutorial, you will learn how to create a centralized rsyslog server to store log files from multiple systems and then use Logstash to send them to an Elasticsearch server. From there, you can decide how best to analyze the data.
GoAccess is a tool for monitoring web server logs in realtime. In this tutorial, you’ll learn how to install and configure GoAccess for Apache on an Ubuntu 20.04 web server. You’ll access different log files with the program before walking through the modules available to you and how to navigate between them on the command-line interface.
