Infrastructure monitoring is a critical component of IT management that ensures optimal performance and reliability of hardware and software resources supporting an organization's IT environment. It provides real-time insights into the entire stack, enabling proactive problem detection, capacity planning, compliance, and post-deployment feedback. The benefits of implementing a robust infrastructure monitoring system include improved performance and reliability, cost savings, scalability, future-proofing, and enhanced observability. An effective infrastructure monitoring tool should provide comprehensive monitoring capabilities, supports a wide range of technologies, offers real-time monitoring with customizable alert thresholds, collects historical data for trend analysis, and has transparent pricing. New Relic is a popular choice for infrastructure monitoring due to its consumption-based pricing model, seamless collaboration across teams, and ability to break down data silos for rapid remediation.
