Agentless Monitoring
Agentless monitoring is an IT infrastructure monitoring approach that collects data from systems, applications, and networks without installing dedicated software agents on the target devices. It relies on standard protocols and APIs to gather metrics, logs, and performance data remotely, reducing deployment complexity and resource overhead. This method is commonly used for monitoring cloud environments, virtual machines, network devices, and legacy systems where agent installation is impractical or restricted.
Developers and IT professionals should use agentless monitoring when managing cloud-native or hybrid environments, as it simplifies scaling and avoids performance impacts from agents on monitored systems. It's particularly valuable for compliance-sensitive or legacy systems where software installation is prohibited, and for rapid deployment in dynamic infrastructures like containers and serverless architectures. Agentless approaches also reduce maintenance overhead and are ideal for monitoring network devices, storage arrays, and hypervisors through protocols like SNMP, WMI, or SSH.
