Reviving older methods like SNMP can solve inventory issues in operational technology.

Operational Technology (OT) has become a buzzword in the industrial and manufacturing sectors, promising improved automation, control, and efficiency. However, one of the significant challenges in deploying OT is inventory management. Many organizations are often unaware of their digital assets, which hampers the effective use and maintenance of OT systems. This lack of awareness stems from the declining use of network management tools, such as SNMP (Simple Network Management Protocol) pollers, which have been around for decades but are not adequately utilized in the OT landscape.

The Importance of Inventory Management

Inventory management in OT involves keeping track of all digital assets, including devices, sensors, switches, and other network components. Effective inventory management ensures that organizations have a clear understanding of what devices are in use, their performance metrics, and their access patterns. This information is crucial for maintaining optimal network performance, troubleshooting issues, and planning for future upgrades.

The Role of Network Management Tools

Network management tools, such as SNMP pollers, are designed to monitor and manage networked devices. These tools can collect a wealth of information from network switches, including:

  • MAC Addresses: Each device connected to a switch has a unique MAC address, which can be linked to a specific vendor.

  • Access and Performance Data: Switches record when and how devices access the network, as well as performance metrics such as data transfer rates and error rates.

By leveraging these capabilities, organizations can maintain a comprehensive inventory of their digital assets, including vendor information, usage patterns, and performance statistics.

The Decline of SNMP Pollers

Despite the availability and effectiveness of SNMP pollers, their use has declined in recent years. Several factors contribute to this decline:

  • Lack of Awareness: Many organizations are not aware of the capabilities of SNMP pollers and other network management tools. This lack of awareness leads to underutilization of these tools.

  • Complexity: Setting up and maintaining SNMP pollers can be complex, requiring specialized knowledge and expertise. Some organizations may lack the necessary skills or resources to deploy these tools effectively.

  • Neglect of Legacy Tools: With the focus on new and emerging technologies, many organizations neglect legacy tools like SNMP pollers, assuming they are outdated or irrelevant.

The Consequences of Poor Inventory Management

Without effective inventory management, organizations face several challenges:

  • Lack of Visibility: Organizations cannot make informed decisions about their OT infrastructure without a clear understanding of their digital assets. This lack of visibility can lead to inefficiencies and increased downtime.

  • Increased Risk: Unmonitored devices can pose security risks, as they may be vulnerable to cyberattacks or unauthorized access.

  • Ineffective Maintenance: Without performance and access data, organizations struggle to identify and address issues proactively, leading to reactive maintenance and increased operational costs.

Revitalizing Inventory Management in OT

To address these challenges, organizations need to revitalize their approach to inventory management by:

  • Leveraging Network Management Tools: Organizations should reintroduce tools like SNMP pollers to monitor and manage their OT infrastructure effectively. These tools provide valuable insights into device performance and access patterns.

  • Training and Awareness: Investing in training and awareness programs can help organizations understand the importance of inventory management and how to use network management tools effectively.

  • Integrating Modern Solutions: While SNMP pollers are effective, integrating them with modern network management solutions can enhance their capabilities. This integration can provide a more comprehensive view of the OT infrastructure, combining legacy data with real-time analytics.


Effective inventory management is crucial for the successful deployment and maintenance of OT systems. Despite the availability of tools like SNMP pollers, their declining use has left many organizations unaware of their digital assets. By revitalizing the use of network management tools and investing in training and awareness programs, organizations can maintain a comprehensive inventory of their digital assets, ensuring optimal performance, security, and efficiency in their OT infrastructure.
