New Relic's Health Map is a visualization tool that integrates application and infrastructure monitoring data to help operations teams understand and troubleshoot their applications. It provides a high-density, color-coded view of the health of all applications and the infrastructure hosts where they are deployed, making it easier for teams to track dependencies and identify performance issues. With Health Map, teams can gain a unified view of their applications and infrastructure, automatically detecting relationships between them and providing insights into application and infrastructure health through color-coded visualization and basic metrics. The tool also offers filters to quickly find specific applications or hosts and provides drill-down capabilities to troubleshoot issues within New Relic APM or Infrastructure.
