SNMP Monitoring Software

If your network devices speak SNMP, you need reliable, user-friendly software to monitor them. Intermapper gives you powerful SNMP network monitoring you can count on.

What is SNMP monitoring?

SNMP monitoring for IT and network professionals

SNMP is one of the most commonly-used communications protocols online. Short for “Simple Network Management Protocol,” it belongs to the application layer of the Internet protocol suite, a set of popular online protocols. Other protocols in the application layer include HTTP, FTP, SMTP, and DHCP.

SNMP originated in the 1980s as networks were growing in size and complexity. Today network administrators use SNMP to get performance information about the devices on their network. SNMP monitoring includes getting data from SNMP-enabled devices about their activity, like bytes, errors transmitted and received, or connection speed.

What benefits does SNMP monitoring software provide?

You need a way to manage all your network devices. It can be overwhelming to try to manage it all, especially if you have a small network team, or if you have a rapidly-growing network.

Monitoring software for SNMP helps capture information about how your SNMP-enabled devices are performing. Most devices speak SNMP, and this could include everything from network equipment and servers to printers and applications.

A monitoring tool can also help with inventory and asset management and security.

Lastly, a reliable SNMP monitoring tool helps anyone reliably monitor large quantities of data from a single console with limited resources—even if you're a one-person IT team. More efficient monitoring can give you peace of mind, knowing you can monitor traffic in real time, identify performance slowdowns, avoid bandwidth and server performance issues, spot trends, and improve the overall health of your network.

How Does Intermapper Monitor SNMP?

Intermapper uses SNMP probes to query network devices for their management information base (MIB) variables. Those MIBS give you a greater range of SNMP monitoring. Out of the box, Intermapper comes with all kinds of general and vendor-specific probes, including: 

  • Basic OID
  • Comparison
  • High, Low, or Range Threshold
  • Restricted Interface
  • Single OID Viewer
  • SNMP High PPS
  • SNMP High Traffic
  • String Comparison
  • Table or Trap Viewer
  • And more!

If you need a different SNMP probe, check out our user-contributed probes library. Customers constantly share custom SNMP probes and other types of probes for the whole Intermapper community to use.

You can also create your own custom SNMP probes. Here is a helpful article on how to create an SNMP probe.  

How much does Intermapper cost?

How much does Intermapper cost?

You can get started with Intermapper for free and monitor up to 10 devices. Beyond that, Intermapper is priced by the number of network devices you want to monitor. You can monitor unlimited components per device. Subscription pricing starts at $303 for 25 devices, and our device-based licensing starts at $765 for 25 devices (including one year of software support).

Getting Started with Intermapper SNMP Monitoring

Getting Started with Intermapper SNMP Monitoring

If you’re ready to try Intermapper for SNMP monitoring, you can download our free 30-day trial or our free 10-device version. Either is a fantastic way to evaluate what Intermapper can do.

Once you download and install Intermapper, Intermapper will use the SNMP traffic probe to query any SNMP-speaking devices.

You can scan your network specifically for devices that speak SNMP, assign special SNMP probes to monitor your equipment, create your own SNMP probes, create SNMP trap notifications, and more. The Intermapper user guide is an excellent place to start to learn about Intermapper and SNMP. The Intermapper Knowledge Base also has a section about Intermapper & SNMP.

Three SNMP Versions

There are three versions of SNMP. Here's a quick summary of each version and how they differ:

SNMPv1

The first version of SNMP was characterized by easy setup, 32-bit counters, and little security. The community string is sent in plaintext. 

SNMPv2c

Version 2 added support for 64-bit counters and the Inform command.

SNMPv3

Version 3, the most advanced version yet, provides additional user-based security features through authentication and encryption. If you haven’t yet upgraded to SNMPv3, it is more complex than the previous versions to setup, but it is highly recommended for its security benefits.  

Seven SNMP Protocols

There are seven different SNMP protocol types. The four that are most commonly used by network administrators include GetRequest, GetNextRequest, Response, and Trap. Intermapper only requires read-only access to any of the “get” commands.

1. GetRequest

This is a manager-to-agent command requesting specified variables.

2. SetRequest

This is a manager-to-agent request to change specified variables.

3. GetNextRequest

This is a manager-to-agent command to deliver available variables returning a response with variable binding for the lexicographically next variable in the MIB.

4. GetBulkRequest

Similar to the GetNextRequest, this manager-to-agent request asks for multiple iterations of GetNextRequest.

5. Response

This is an agent-to-manager response bringing back variable bindings and acknowledgement for GetRequest, SetRequest, GetNextRequest, GetBulkRequest, and InformRequest. 

6. Trap

This is a notification from agent to manager allowing the agent to send notification of important events using SNMP messages.

7. InformRequest

This is manager-to-manager notification.
