What is Agentless Network Monitoring

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  

Why Agentless network monitoring?

The debate between Agent based and Agentless monitoring is one that has been happening for long in the network management industry. However, most companies prefer Agentless network monitoring since it takes the upper hand through the following advantages:

  • Reduced deployment time – Since there are no agents involved, only the monitoring server needs to be configured and hence, deploying an Agentless network monitoring tool is a hassle free process. you can get the network monitoring infrastructure running in no time without going to through complex setup processes.
  • Reduced Management Overhead – The absence of agents makes the network monitoring infrastructure easier to maintain. Most of the Agentless Network Monitoring Tools come with self-monitoring features which makes the maintenance process very simple and less time consuming.
  • Easy to upgrade – In case of an Agent based network monitoring infrastructure, whenever the network monitoring tool or a network component is upgraded, all the agents in the network have to be upgraded. Agentless network monitoring environments do not have this problem.
  • Reduced fault overhead- In case of Agent based monitoring, the failure of an agent will stop the monitoring process for all the devices connected to that Agent. This problem does not occur in Agentless monitoring where the monitoring of devices is not affected by external factors.
