Agentless network monitoring is a technique in which the monitoring server directly polls the devices in the network periodically to monitor their health and performance. This method is more reliable and efficient when compared to agent based monitoring in which the data required for monitoring the health and performance of the network devices is collected by agents and transferred to the network monitoring tool.
