Tools for collecting, analyzing, and visualizing system and application logs.
Overview
Log Management Tools
Log management tools are solutions for efficiently collecting, storing, searching, and analyzing large volumes of log data generated from IT infrastructure and applications. Starting with representative tools such as ELK Stack (Elasticsearch, Logstash, Kibana) and Splunk, there are diverse options ranging from open-source to commercial products. These tools play a central role in operational monitoring and security operations, including early detection of system failures, security threat detection, performance analysis, and compliance management. In 2025, OpenTelemetry standardization and cloud-native support have advanced, enabling more efficient log management.
