New Relic integrates seamlessly with RMQ and Redis, offering enhanced functionality and real-time insights via dashboards. Its efficient alerts through Slack and PagerDuty and comprehensive monitoring make it valuable. However, high pricing, AWS integration challenges, and limited documentation, particularly for Windows, present issues. Improvements in alerting, dashboarding, and scalability are needed, especially for infrastructure. Despite these, New Relic's performance optimization through latency and bottleneck identification is commendable.
