Infrastructure Monitoring platforms track the health, availability, and performance of the IT infrastructure estate — servers, networks, hypervisors, storage, databases, and cloud services. Core capabilities include agent and agentless metric collection, up/down and threshold alerting, service dependency and topology mapping, event correlation and noise reduction, dashboards and reporting, log collection for IT ops contexts, and increasingly AIOps capabilities (anomaly detection, root-cause hints). The category is distinct from application performance monitoring (APM, which traces application-level code paths and is predominantly an engineering purchase) and from cloud cost management — Infrastructure Monitoring is focused on availability and performance of the IT estate rather than code profiling or financial allocation.
