SNMP one of the most popular, if not the most popular, protocol for polling networking devices for information – We're going to dive into the Best SNMP Monitoring Tools & Software and find out how they rank amongst each other in terms of price, features and capabilities!
SNMP, or Simple Network Management Protocol, is a protocol that is used by a multitude of different devices that connect to IP networks. You can think of it as a useful tool that allows us to gather information about your current network environment.
Because it such a common software component and is compatible with nearly all network devices, many monitoring tools use it, which allows system and network admins a clear picture of what is happening in real-time.
Here is our list of the best SNMP Monitoring tools:
- SolarWinds Network Performance Monitor – FREE TRIAL An SNMP-based network device monitoring service that interprets SNMP Trap messages from device agents into alert notifications. Runs on Windows Server.
- Datadog Network Monitoring – FREE TRIAL A cloud-based infrastructure monitoring platform that uses SNMP for device health checks and also network traffic data.

Some items that require monitoring are server usage stats, such as CPU utilization, RAM usage, Hard Disk Space, Network traffic on the LAN interfaces, and other critical information that relates to your server infrastructure.
If your environment is highly populated with tens or even hundreds of servers, then SNMP allows your applications to read this data as it becomes available, so that you can start troubleshooting and repairing these issues as they occur.
SNMP also gives similar stats about network hardware, such as firewalls, routers and managed switches, and can even relay supply level information from office equipment such as network copiers and printers.
Today we will be looking at 10 such SNMP Monitoring tools and software, and we will see what the main differences are between them.
This will help you in your decision making when looking to get a new software package for your environment, and hopefully will allow you to avoid choosing a software package that doesn’t do what you need it to.

2. Datadog Network Monitoring – FREE TRIAL
Datadog is a cloud-based platform for infrastructure monitoring and management. Two of the modules offered by Datadog are the Network Performance Monitor and the Network Device Monitor.
The Network Device Monitor relies on the SNMP system to query device agents and gather status reports. The monitor also listens for SNMP Trap messages from agents that warn of developing problems.
The Datadog Network Performance Monitor is concerned with traffic flows. SNMP isn’t native to this service. However, it has an SNMP integration that can be activated for free. This adds traffic information that is available from SNMP reports sent by device agents. The reports detail the throughput of each port on each switch.
The Datadog service is based in the cloud and that provides the servers to run the software on. The console for the network monitoring services is accessed through any standard browser. Setup is very straightforward. The service will download an agent onto a host on the network to be monitored and that will gather all information on all network devices and populate the monitoring screens automatically with a network inventory. Datadog offer a 14-day free trial.
- Device status tracking
- AI-based performance thresholds
- Alerts for developing problems
- Automatic device discovery
- Automatic network topology mapping
- Hosting costs included in the price
- Offers numerous real user monitors via templates and widgets
- Can monitor both internally and externally giving network admins a holistic view of network performance and accessibility
- Changes made to the network are reflected in near real-time
- Allows businesses to scale their monitoring efforts reliably through flexible pricing options

3. Site24x7 Network Monitoring – FREE TRIAL
Site24x7 is a cloud-based system monitoring platform that is able to supervise networks, servers, applications, and websites anywhere in the world. The service list of Site24x7 includes a Network Manager.
This tool is not available as a standalone service. It is part of the following plans:
- Website Monitoring
- Application Performance Monitor
In each case, the plan gives monitoring capabilities to a limited number of device interfaces – for example, on the Infrastructure plan, this is only five but 50 on the MSP plan. In order to thoroughly monitor a network with SNMP, you will need an interface allowance that is a lot more than five. These extra allowances are available for an upgrade fee.
The Network Monitor uses SNMP to search out all of the devices connected to the network. It compiles an inventory from the received device status reports and will update this with each report request, should any differences in the number of devices be identified. The service creates a live topology map from the network inventory.
SNMP device reports get interpreted into graphs and charts in the system console. The service also converts SNMP Trap messages into system alerts. These alerts can be forwarded to technicians by SMS, email, voice call, or instant messenger post.
- Hosted service
- Regular SNMP polling
- Device discovery
- Automatic network topology map
- Drill-down data presentation
- Graphs and charts of live data
The dashboard for the Network Monitor is resident in the Cloud and can be accessed through any standard Web browser. All of the screens can be customized by dragging and dropping elements or adding widgets.

No matter what your reasons are for wanting to keep an eye on your network in real-time, there is no shortage of perfectly capable products on the market, both paid for and free. Which product you choose will ultimately depend on what your feature requirements are, and how much of a role your product support will need to play if you are going to be maintaining the system yourself.
Smaller businesses can certainly benefit from a free or open source application, but established companies with sites located around the world will need a solution that is scalable and more substantive than a free application. Each of these products have their own key benefits that distinguish themselves from one another, so when deciding on which one is best for you, decide on what you need to be monitoring in the first place.
Once you understand your operational requirements in terms of reporting and monitoring, you can take the next steps towards implementing a solution within your business. Most of these applications have trial versions that you can install for testing purposes, so that is a great place to start.
