The Best SNMP Monitoring Tools
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.
Pros:
- 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
Cons:
- No on-premises version
You can assess Auvik with a 14-day free trial.
EDITOR'S CHOICE
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.

2. Datadog Network Device Monitoring – FREE TRIAL
Datadog Network Device Monitoring watches the performance of a network by querying the switches and routers that connect links together. These status requests are performed through the use of the Simple Network Management Protocol.
Device agents pass activity reports to the SNMP manager, not just system statuses. So, the Network Device Monitor is able to report on live traffic throughput at each node on your network.
As an SNMP manager, the Datadog system can process SNMP Trap messages into alerts. You can set thresholds on any of the statistics that the Network Device Monitor gathers and breaches of those levels also trips alerts.
Pros:
- Automatically discovers all devices on the network
- Regularly gathers status reports from switches and routers
- Tracks live traffic throughput bat all points on the network
- Receives Trap messages from device agents to identify operational problems
- Forwards alerts to technicians by email or Slack message
- Includes analytical tools to aid network performance optimization
Cons:
- The free trial only lasts for two weeks
Datadog Network Device Monitoring can be set up to forward alerts to technicians via email, Slack, PagerDuty, Jira, and Webhooks. This means that you can leave the system to monitor all of your network because you will be drawn back to the dashboard if problems start to evolve. You can start a 14-day free trial.

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:
