What Agentless Monitoring?

Monitoring IT infrastructures often involves the installation of agent software on target servers to collect performance metrics about the servers and application servers executing on them. The need to install and maintain agent software on all monitored servers is a key drawback with this approach.

Agentless monitoring collects performance metrics from the infrastructure without installing any agent software on the servers or devices being monitored – which makes the agentless approach easier to manage.
