In today's complex network of switches, routers and servers, it is a daunting task to manage all the devices. Eventually, the network begins to slow down due to the frequent network issues. Hence it is critical to keep an eye on the entire network. But is it possible for the network admin to stay in front of the monitoring system constantly? Hence, a proactive network monitoring software will keep you informed of the processes happening inside your network.

Most of the devices on the network support the network management protocol. It allows network devices to share management information more easily. Various protocols exist to support network management, including the Simple Network Management Protocol (SNMP), the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), etc. The most popular SNMP protocol comes pre-bundled with SNMP agents for most network devices.

In this page, you will understand what SNMP monitoring is, the benefits of using a potential SNMP monitoring tool, how to detect network faults quickly with SNMP traps and much more. In short, this is a simple SNMP monitoring guide that will help you understand the basics. Let's get started.

Features of SNMP monitoring tool

SNMP is an application-layer internet protocol that allows network devices to share management and monitoring information.The SNMP protocol is an industry-standard protocol that is easy to use and implement. This protocol enables network devices to communicate despite having different hardware and software, allowing network administrators to track network performance, diagnose and manage network faults, and plan network capacity and growth.

With SNMP performance monitoring, the network admin can quickly and effectively find the performance of network devices. Here is a little of what SNMP monitoring system does:

  • A SNMP network monitoring software helps in monitoring the health and performance of network devices for faults, and manages various network resources like servers, printers, scanners, etc.
  • The SNMP discovery mechanism uncovers network resources and aids in obtaining the configured SNMP credentials of network devices. It also allows auto-discovery to be scheduled on a regular basis.
  • The SNMP management software can monitor the status of all network devices in real time, including CPU utilization, and memory consumption. Windows servers can also have SNMP enabled on all devices so network admins can easily monitor their network.
  • Using SNMP performance monitor, you can track in and out traffic. It also helps to determine the packet throughput and delay during transmission. Based on actionable insights, you can also monitor errors, discards, and assess network performance metrics with the help of the SNMP management software.

However, these are the overview functionalities of SNMP. More features related to SNMP depends on the type of network monitoring software you choose.

Advantages of SNMP monitoring

Here are a few advantages of SNMP monitoring.

  • Since most of the devices are compatible to SNMP, you will be able to centrally monitor a wide range of devices. SNMP provides real time visibility into the performance and health of the network devices.
  • With the help of SNMP traps, quickly identify underlying network issues such as performance degradation, device failure etc and troubleshoot them before it reaches your end user.
  • Understanding the usage trends helps lay the path to planning the capacity utilization of your organization.
  • SNMP is not just a cost effective way to monitor your network, but also helps you define the specific metric you need to monitor.

With these advantages in place, let us see how SNMP monitoring is made easy with ManageEngine OpManager.

OpManager: The comprehensive SNMP performance monitoring solution

ManageEngine OpManager, a network monitoring software that has helped over a million IT admins monitor their network devices across the world, employs asynchronous SNMP trap messaging to obtain management information on network devices. You can monitor availability, network performance, and manage network faults of network devices using the SNMP performance monitoring capabilities of OpManager.

Device discovery

Network device discovery allows you to automatically identify what devices are connected to your network at any given time, enabling you to keep your network's devices organized. With the help of SNMP monitor, OpManager simplifies the process of device discovery and expands it to a wide variety of network devices. With OpManager monitoring SNMP, you can schedule network device discovery to automate the process.

Performance monitoring

Network performance monitoring is a process for tracking and analyzing network events and activities to make necessary adjustments that improve network performance. With SNMP's get and set operations, the network admin can conduct performance monitoring in the network. OpManager, a SNMP network monitoring tool, comes with powerful, insightful reports to help you analyze key performance metrics, such as network availability, response times, throughput, and resource usage which makes SNMP management easy.

SNMP monitoring metrics

Monitoring the network using SNMP helps you to collect a wide range of metrics right from the basic ones like availability, packet loss, response time to the advances ones like temperature, fan speed, CPU utilization, memory utilization, process count, CPU ready and more than 3000 performance metrics.

Fault management

Fault Management addresses detecting, isolating, and correcting network problems. With SNMP's trap operation, you can get the problem report from the SNMP agent running on that machine. The network admin can then decide how to deal with it, by correcting or isolating that problem entity. OpManager's monitor SNMP has alerting system that assures you are notified well in advance of network issues, like breakdowns and performance slowdowns.


With OpManager as SNMP monitor tool, network admins can rapidly detect and focus on network issues thanks to the performance statistics displayed in reports and dashboards. Using its customized dashboards, you can choose from and organize over 200 performance widgets.
