Custom alerts and data visualizations make it easy to monitor, identify, and prevent corrupted data and associated network performance issues. 






Your device’s Management Information Bases at your fingertips

 i How PRTG defines sensors

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

Ensuring your network performs optimally without accessing the Management Information Bases of the devices you want to monitor is like trying to find your way around a city you've never been to before. Blindfolded.

But, the larger and more complex your network is, the harder it is to read and analyze your MIB files – or even integrate them into your monitoring setup.

Our free MIB browser for Paessler PRTG makes reading, analyzing, and changing MIB files quick and effortless. Import files, convert them to the OID format, and set up PRTG sensors in a few clicks. We'll even throw in 100 free sensors so you can keep an eye on your network devices’ health and performance via SNMP.


Flexible, intuitive, cost-effective:

Our MIB to OID converter in action

Once you've downloaded the relevant MIB file from the manufacturer's website, and downloaded and installed Paessler MIB Importer, setting up a PRTG sensor is pretty easy:

  1. In the MIB Importer tool, click File | Import MIB File.
  2. Check the values are correct, then click File | Save For PRTG Network Monitor to convert the file to the .oidlib format. You can also save a copy of the file in PRTG's /snmplib subdirectory.
  3. Go to PRTG and add, for example, an SNMP Library sensor.
  4. Select the entries made available by the new OIDlib file that you want to monitor and get started.


You can create up to 100 sensors for free, including:

PRTG MIB browser: FAQ


1. MIB vs OID: what's the difference?

MIB stands for “Management Information Base”. MIB files contain information you need to monitor and control a router, switch, or other specific network device. An OID or “object identifier”, on the other hand, is a series of numbers that identifies an object in the MIB hierarchy and that can be read via SNMP. Think of it this way: a MIB is like a house you want to get to, and an OIB is the set of coordinates you pop into your GPS so you can reach it without getting lost.

2. Why do I need MIB files?

Because devices from different manufacturers all work differently, it's impossible for monitoring software to cover every possible scenario. MIB files enable you to tailor monitoring sensors to your specific device and situation.

3. What does a MIB converter do?

A MIB converter typically refers to a tool or software that translates Management Information Base files from one format to another. These converters facilitate compatibility between different network management systems or devices that might use different MIB file formats.

4. Where can I find my device's MIB files?

Cisco, Juniper, Dell, and other reputable device manufacturers usually make MIB files available in the downloads section of their websites. The Internet Engineering Task Force, or IETF for short, has published a global MIB standard, and included MIBs in more than 300 of its first 5,000 RFCs.

5. What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.

On average, you need about 5-10 sensors per device or one sensor per switch port.
