The Best SNMP Monitoring Tools & Software for Servers & Network Devices

snmp monitoring tools

Marc Wilson UPDATED: September 12, 2023

Almost every single piece of equipment in your infrastructure has the ability to be Monitored using SNMP protocol. The issue is that many admins overlook the simplicity and availability of SNMP Monitoring for managing their devices.

So we thought we'd make it easier for everyone and compile and compare a list of the Best SNMP Monitoring Tools and Software on the market that make the job easy and simple.

SNMP Protocol allows you to poll device MIBS to extract useful and critical information that will allow you to be proactive about fixing issues that arise before you hear them for your end-users or clients.

Here is our list of the top SNMP monitoring tools:

  1. Auvik – EDITOR’S CHOICE This cloud-based SaaS package uses SNMP procedures to discover all network devices and create a network inventory. That inventory is constantly updated by re-polling for SNMP agent reports and forms the basis for a network map and live status reporting. Get a 14-day free trial.
  2. SolarWinds Network Performance Monitor – FREE TRIAL A system that uses SNMP processes for network discovery, live status checks on devices, and performance alerts. Installs on Windows Server. Start 30-day free trial.
  3. Paessler PRTG – FREE TRIAL A collection of network, server, and application monitors that uses SNMP as its main method for network monitoring. Installs on Windows Server. Start a 30-day free trial.

On top of keeping your up-time high for all your systems and users, monitoring hardware/software Faults, Availability and Performance issues will be at your finger tips, as many of these programs and tools listed before have intuitive and simple interfaces with built-in reporting and graphs to help you manage everything in a centralized location.

Here's a List of the Best SNMP Monitoring Tools & Software

Below you'll find a list of the top tools and software we recommend for those looking for a monitoring and management solution for your network and devices. Most of these have FREE Versions or Trials for you to test our and others require you to pay upfront before testing.

Nevertheless, we recommend you download a couple software packages and test them all out before making a choice, this will help you understand their interfaces and features that they offer individually.

Our methodology for selecting SNMP network monitoring tools and software

We reviewed the SNMP network monitoring tools and software market and analyzed the options based on the following criteria:

  • An autodiscovery system to log all network devices
  • A network topology mapper
  • The ability to collect live network devices statuses by using SNMP
  • A facility to analyze network performance over time
  • Graphical interpretation of data, such as charts and graphs
  • A free trial period, a demo, or a money-back guarantee for no-risk assessment
  • A good price that reflects value for money when compared to the functions offered

With these selection criteria in mind, we have identified the top network performance monitors that use the Simple Network Management Protocol to communicate with switches and routers. We made sure to include options for both Windows Server and Linux.

1. Auvik – FREE TRIAL


Auvik is a cloud SaaS platform that provides a Network Management system. This is based on SNMP and you set it up by installing an agent on one of your servers. The Auvik agent is available for Windows Server and Linux and it acts as an SNMP Manager, uploading all responses to the Auvik server for processing.

The Auvik system compiles SNMP responses into a network inventory and also draws up a network diagram automatically. Each subsequent polling of the network results in updates to the inventory and map. The data from the SNMP sweep is also displayed in the live performance monitoring screen of the Auvik dashboard. An SNMP device agent will send out a notification if it discovers a status issue on its host. Auvik displays these details as an alert in the system console.


  • Web-based dashboard accessible from anywhere
  • Centralizes the monitoring of multiple LANs
  • Processes SNMP responses
  • Identifies when devices are added, moved, or removed
  • Displays SNMP traps as alerts in the system dashboard
  • Create a network inventory and network diagram


  • No on-premises version

You can assess Auvik with a 14-day free trial.


Auvik is our top pick for an SNMP monitoring tool for servers and network devices because the package, although based in the cloud, downloads a collector program onto one of your servers. That module acts locally as the SNMP Manager. The Auvik agent sends out frequent SNMP requests and compiles the responses into live network monitoring data, a network inventory, and a network topology map. Activate an SNMP agent on your servers to get them included in the monitoring service.

SNMP monitoring FAQs

Why does SNMP use 2 ports?

The SNMP manager sends out its requests from any port – that port isn’t specified in the standard. The important port for requests is UDP 161. This is the port on the device that receives the request. If a device raises a Trap message, it sends the packet to UDP port 162 on the SNMP manager. If Transport Layer Security (TLS) or Datagram Transport Layer Security (DTLS) is in operation to protect SNMP messages, those ports change: the SNMP manager sends requests to TCP port 1061 and Trap messages go to TCP port 1062.

What protocol does SNMP use?

SNMP is its own protocol, it is called the Simple Network Management Protocol. The standard is defined in many documents that are free for anyone to access and are called RFCs. These are maintained by the Internet Engineering Taskforce (IETF). Look for RFC 3411 to RFC 3418.

What is the difference between SNMP and SMTP?

Although SNMP and SMTP sound similar, in reality they are very different. SNMP is the Simple Network Monitoring Protocol and it defines a system for status reporting between network devices and a central controller. SMTP is the Simple Mail Transfer Protocol, which defines the method of getting an email from the sender’s email client program through to the mail server of the recipient.

What should you look for in free network monitoring tools?

We reviewed the market for free network monitoring software and analyzed the options based on the following criteria:

  • Capabilities to poll for device statuses with SNMP out of the box
  • The ability to receive and process Trap messages into alerts
  • Live performance graphs in the dashboards
  • A self-installing, easy-to-use package
  • Autodiscovery of network devices that repeats continuously
  • A free trial or demo system that allows a no-risk assessment
