Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Agentless networking monitoring allows companies to avoid the challenges and overhead of installing and maintaining software agents on the monitored systems.

It is important for companies of all sizes to have a robust infrastructure monitoring system in place. This is because a well-monitored infrastructure can help prevent downtime and other issues that can impact business operations.

In today’s digital world, even a brief outage can have significant consequences, so it is important for companies to have the tools and systems in place to monitor their infrastructure and quickly identify and address any potential issues.

A seamless infrastructure monitoring experience can help companies minimize disruptions and maintain high levels of uptime and performance.

Due to the fact that agentless monitoring does not rely on an intermediary device to collect information metrics from end devices, it has become one of the most effective techniques for managing network operations.

What is Agentless Network Monitoring?

Agentless network monitoring refers to a type of network monitoring that does not require the installation of agents (software programs that run on individual devices and report information to a central monitoring system) on the devices being monitored.

Instead, this type of monitoring relies on technologies such as SNMP (Simple Network Management Protocol) and WMI (Windows Management Instrumentation) to remotely collect data from network devices and provide real-time visibility into their performance and health.

Agentless monitoring has several advantages over traditional monitoring methods that rely on agents. First, it eliminates the need to install and maintain software agents on the devices being monitored, which can save time and resources.

Second, because it does not rely on agents, it can be used to monitor devices and servers that may not be able to support agents, such as embedded devices or services running on non-standard operating systems.

Finally, agentless monitoring can provide better security, as it does not require the installation of potentially vulnerable agents on the monitored devices.

Why it is Required?

Agentless network monitoring is required because it provides real-time visibility into the performance and health of network devices without the need to install agents on individual devices. This can be beneficial in a number of ways, including:

  • Improved network performance: By providing real-time visibility into the performance of network devices, agentless monitoring can help identify and resolve potential issues before they impact network performance and uptime.
  • Reduced IT costs: Because it does not require the installation of agents on individual devices, so it reduces IT costs.
  • Enhanced security: Agentless monitoring can help enhance security by allowing IT teams to quickly detect and respond to potential security threats on the network.

Features of Agentless Network Monitoring

Features-of-Agentless-network-monitoring

Some key features of agentless network monitoring include:

  • Remote data collection: Agentless network monitoring uses technologies such as SNMP and WMI to remotely collect data from network devices, allowing real-time visibility into their performance and status without needing physical access.
  • Real-time monitoring: These monitoring systems provide real-time visibility into the performance and health of network devices, allowing for quick detection and resolution of potential issues.
  • Scalability: Because it does not require the installation of agents on individual devices, agentless network monitoring is highly scalable and easy to use and can be easily deployed across large networks.
  • Automated alerting: These monitoring systems often include automated alerting capabilities, allowing them to send notifications to designated individuals or teams when potential issues are detected.

There is no single best agentless network monitoring tool, as the best tool for a given organization will depend on a range of factors, such as the size and complexity of the network, the specific requirements of the organization, and budget constraints.
