Docker containers generate logs to monitor their operations, but without a mechanism in place to manage these logs, they can grow indefinitely, leading to excessive disk space consumption and performance degradation. Implementing docker log rotation is crucial to control log file size and quantity, ensuring efficient log management and optimal system performance.

Splunk and Dynatrace are popular monitoring tools widely used by businesses for tracking and monitoring data. Dynatrace is different from Splunk as it provides full-stack observability with AI-driven root cause analysis for applications, infrastructure, and user experience, while Splunk focuses primarily on log management and data analysis. Splunk can also be used for monitoring, including infrastructure monitoring, application performance monitoring, server monitoring, and continuous monitoring.

New Relic and Splunk are two prominent tools in the world of observability and monitoring, each serving distinct purposes. New Relic is used for Application Performance Monitoring (APM), offering a full-stack observability platform. It is important to note that New Relic is not a SIEM tool, its primary focus is performance monitoring. On the other hand, Splunk is used for log management, machine data analytics, and is widely utilized as a SIEM tool.

New Relic and Grafana are leading tools in monitoring and observability, each with distinct use cases. New Relic excels in Application Performance Monitoring (APM), providing detailed insights for application performance. In contrast, Grafana is designed for data visualization and monitoring, allowing users to create customizable dashboards for metrics and logs. This article provides a clear comparison of their features, including application performance monitoring, log management, and dashboards.
