What is SNMP?
SNMP (Simple Network Management Protocol) is a scanning technology that is used as a Network Discovery tool and data gatherer. Many network scanning tools use SNMP as a means to collect valuable information about the current state of devices on the immediate network.
Things like printers, computers, servers, and even some versions of software are detectable from SNMP capable applications, so it is very useful and effective in administering and managing your company’s resources.
There are other benefits to it as well, such as finding out serial numbers of your hardware, and even warranty stats and toner and ink levels in printers around the office.
We want to look at some of the products that you can use to try and get your network in tip top shape, with no unknown quantities being in the mix.
A known quantity on a network is far better than anything that will take you by surprise much later, such as a rogue device like a small computer or network device.
The Best SNMP Scanner Tools and Software of 2023
1. SolarWinds SNMP Scanner – FREE TRIAL
SolarWinds SNMP Scanner is a mapping tool that lets you discover and monitor everything on your network. It helps you discover network devices by performing SNMP sweeps and discovers and collects many detailed configuration reports about the entities on the network. Because of the way it scans and collects, it gives you the ability to map and create an overview of the current state of the network.
One of the great benefits of using this application is that it lets you monitor faults on the network, the availability of devices as well as the overall performance of the network. Performance metrics and MIBS data ensures that you have an accurate picture of the current state of network health and speed.
SolarWinds SNMP Scanner is especially useful in large and complex environments where there are devices from multiple vendors that you might not be able to monitor from traditional network scanning tools.
The mapping element means that you can easily detect and keep your environment up to date and labeled correctly. You can visualize in real-time whenever there are any errors on the map, as well as utilization stats for each of your links.
If a link goes down then you will know about it almost immediately with the Down Status indicator on your global map.
Overall this is a great tool that adds an additional layer of functionality to your network and will allow you to see any changes and faults as they come up within the environment.

2. ManageEngine OpManager – FREE TRIAL
ManageEngine OpManager monitors networks and servers. The network monitoring part of the package is heavily reliant on SNMP for its functions.
The OpManager network monitor starts its service life with an initial SNMP request poll. The OpManager system acts as the SNMP Manager and receives back MIBs from all device agents in response to its request broadcast. The service compiles all of the MIB information for a performance report page for each device.
The device report offers live performance statistics. The OpManager module repeatedly sends out status requests, refreshing the device performance screen with each cycle and compiling time-series graphs for selected metrics.
The initial performance screen gives the vital metrics for that device and you can select which pieces of information appear on that screen. However, a back screen provides all data returned in the MIB.
The OpManager dashboard also displays status alerts, which are derived from any Trap messages sent back by agents. The settings of OpManager allow you to specify an email account or mobile number to which the service can forward alerts as email or SMS notifications.
Other features in the OpManager package are server monitoring, Active directory monitoring, web and email server monitoring, VLAN monitoring, and virtualization monitoring. All of the services and software that the system monitors are measured by performance thresholds that will generate alerts if crossed.
Pros:
- Can automatically produce metrics such as unused addresses, IP conflicts, and available IP addresses based on subnet
- Leverages both ping and SNMP protocol to detect device uptime and performance issues
- Build an automatic network topology map updated in real-time
- Has log collection capabilities, allowing it to provide much more detailed information than other tools
Cons:
- OpManager is a tool designed for IT professionals, non-technical users may find the platform overwhelming
ManageEngine OpManager is a software package and it installs on Windows Server and Linux. There are four editions of the package.
