6 Best MIB Browsers

By Staff Contributor on June 3, 2020

MIBs, short for Management Information Bases, are hierarchical databases of information pertaining to monitored devices. They can be accessed through MIB browsers, which retrieve data from SNMP-enabled devices like servers, routers, or switches.

There are several MIB browsers on the market, including professional options and free and open-source tools. All these are designed to help you manage SNMP devices and access information in MIBs in a usable and efficient way. I recommend SolarWinds® Engineer’s Toolset, which bundles MIB tools with a wide range of utilities to help you maintain your network as a whole.

Understanding SNMP

Before we get into MIB browsers, a basic understanding of SNMP will be helpful. SNMP, or Simple Network Management Protocol, is used for collecting information about managed devices on IP networks. It can also be used to modify or organize information on those same devices, which include hosts, servers, printers, routers, and switches. SNMP-enabled managed devices can understand SNMP, which allows you to communicate with them from a networking perspective.

Understanding MIBs and MIB Browsers

A Management Information Base, or MIB, is a virtual database organized hierarchically. Essentially, a MIB is a collection of definitions for the “managed objects” within the device being managed.

Within the MIB hierarchy, OIDs, short for Object Identifiers, point to managed objects. An OID is usually an address matched to a particular device. You can use the OID associated with devices to check device information, performance, sensor data, and so on. Simply put, MIB translates the OID, enabling a management station to understand the device status and related information.

You can access MIBs using SNMP by connecting through a MIB browser—also known as an SNMP browser. For example, if you were monitoring a printer, you’d want to know the different printer cartridge states, how many files had been printed, traffic on the device, and whether there’s any packet loss in the connection to the printer. The MIB browser allows you to pull out data from the printer in a format you can understand.

Best MIB Browsers

Although all MIB browsers assist you in understanding and working with your device data, their features and capabilities vary. Some MIB SNMP browsers are text-based, others resemble spreadsheets, and still others have a simple GUI showing MIB data in a list. In making your choice, you’ll want to think about how much information you need from a browser.

Although I’ve included some free tools in this list, it’s important to remember in a professional or enterprise environment, a free MIB browser may not be sufficient. In addition, network engineers and troubleshooting staff usually need a solution beyond a simple MIB tool, so the ideal MIB browser will come as part of a larger offering.

SolarWinds Engineer’s Toolset

Paessler MIB Importer

Paessler MIB Importer

Paessler MIB Importer is a free SNMP MIB browser for use in combination with Paessler PRTG Network Monitor. It monitors SNMP devices using MIB data files supplied by the device vendor and converts the MIB data into an OID library, which PRTG then accesses to display monitoring and device health information.

MIB Importer has three main sections: the global header bar, which contains the main menu; a window on the left, which displays the OIDs in a tree once you have imported a MIB; and a window on the right, which displays the properties of the OID you have selected. You can import MIB files either with drag and drop, or manually.

Paessler MIB Importer is a free tool, but to integrate it with the PRTG monitoring solution, you either need to download the (limited) free version of PRTG or pay for the enterprise version.



OiDViEW SNMP MIB Browser covers network management and network analysis. It uses SNMP communication to connect with devices on your network and will run on all Windows operating systems. It manages all SNMP-enabled devices on your network, including routers, switches, printers, and servers and probes.

You can use OiDViEW to load standard and proprietary MIB files and to view and edit data in the SNMP agents. In addition, it can analyze SNMP MIB walk files from numerous vendors.

The software uses two technologies that play a large role in how it functions: MIBSense and MIBAcquire. These allow you to determine the correct vendor for the SNMP agent on your device, and then download and install the relevant MIBs. OiDViEW can then load the necessary MIBs at will. This helps you speed up your device monitoring process and automates tasks that would otherwise take a significant amount of time.

In addition, you can view windows with MIB tree representation and agent OID/value responses, searchable MIB variable grids, and MIB variable definition details. If in a session you only query some MIB variables, or if some are missing, OiDViEW flags which of those have been examined and which have not. You can also store your sessions for later use.

OiDViEW SNMP MIB Browser is a free tool, available as part of OiDViEW Console, which comes in both a Professional and an Enterprise version. You can download a free trial of the more complete Console tool as well.
