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.
Advantages of agentless network monitoring software
Most companies prefer agentless performance 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 solution, a tool which is 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 basic 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.
When should an organization choose an agentless network monitoring software?
The debate between agent based and agentless monitoring is one that has been happening for long in the network management industry. However, many organizations choose agentless network monitoring tools based on specific requirements of the organization. But in cases the organization has the following scenarios, switching to agentless network monitoring software is highly recommended.
The organization is huge with a lot of network devices, then using an agentless network monitoring software is recommended because it does not require installing an agent on each device.
It is independent of any platform as it can be used to monitor a wide range of network devices without the need for separate agents for dedicated platforms.
Organizations looking to save some money can choose agentless network monitoring software as they eliminate the need to purchase additional license for monitoring these agents. Not just that, the costs incurred in maintenance of these agents can also be saved.
Agentless network monitoring solution can be employed in a wider range of network environments. This makes it more flexible for various organizational needs.

Unlike agent-based network monitoring, agentless monitoring monitors the assets in the network with the help of protocols which are already installed in the devices and application to collect the required data. These protocols, commonly are WMI, SNMP, NetFlow which basically are device dependent. The devices in the network are just configured to communicate and exchange information with agentless network monitoring tool.
Why is agentless network monitoring important?
+
One of the main reasons to choose agentless network monitoring over agent-based monitoring is to save time and effort, which in turn cuts down cost. This type of monitoring is best for beginners as it lowers ownership compared to agent-based monitoring. Also, it is highly suitable for centralized network with limited resources. Agentless network monitoring is of great help to small organizations without the need to install agents for every set of devices. Hence, they are less intrusive with more flexibility than agent-based network monitoring.
