Versions:
New Relic Infrastructure Agent is a lightweight, always-on daemon designed for systems administrators, DevOps teams, and site-reliability engineers who need continuous visibility into the health, configuration, and performance of every server in their estate. Once installed on Windows, Linux, or containerized hosts, the agent automatically inventories hardware specifications, installed software, network interfaces, running processes, and cloud metadata, then streams time-stamped metrics—CPU, memory, disk I/O, network throughput, and custom attributes—to the New Relic observability platform every five seconds. The resulting data populates curated dashboards that surface anomalous spikes, forecast capacity constraints, and correlate host-level issues with application errors or distributed traces captured by other New Relic agents. Typical use cases include real-time alerting when disk utilization exceeds 90 %, tracking kernel version drift across a Kubernetes cluster, validating auto-scaling behavior after a deployment, and generating compliance reports that prove patching cadence. Because the agent supports tagging, teams can slice data by environment, service, or cost center, while role-based access controls ensure that only authorized personnel can mute alerts or acknowledge incidents. Version 1.72.8, released as the twenty-fourth iterative update since the agent’s introduction, adds improved checksum validation for configuration files, reduces CPU overhead on NUMA systems, and introduces experimental support for ARM64 Windows nodes. The agent is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
