Managing logs at scale has evolved beyond mere storage to involve rapid insights, system health maintenance, and real-time troubleshooting, particularly within the context of cloud-native architectures. A range of open-source log management tools, including Logz.io, the ELK Stack, OpenSearch, Grafana Loki, and Graylog, offer various deployment models, performance capabilities, and cost structures, each with unique strengths. Logz.io provides a fully managed SaaS experience with AI insights and seamless OpenTelemetry integration, making it ideal for comprehensive observability pipelines. The ELK Stack is best suited for teams with Elasticsearch expertise, while OpenSearch offers AWS-native functionality. Grafana Loki is optimal for teams already utilizing Grafana, and Graylog appeals to those desiring extensive control over log processing. The choice of tool depends on factors such as deployment simplicity, scalability, insights capability, and overall cost-effectiveness, emphasizing the importance of aligning log management solutions with specific organizational needs and expertise.
