Paessler MIB Importer and Converter

Monitoring SNMP Devices Using Vendor Supplied MIB Data Files

With this freeware tool you can import MIB (Management Information Base) files and convert them into OID libraries for PRTG.


Please choose a version. There is an alpha version available with the latest features, but also former versions. Please uninstall previous versions before installing a new one.

Alpha Version
(for PRTG 12 or Later)

We recommend that you try the alpha version first. If it does not bring the expected results, you can still switch to the stable version. Any feedback is welcome!

MIB Importer 3.4.8 Alpha (1.9 MB)

Stable Version
(for Older PRTG Versions)

Choose the stable version (for PRTG 7 or later) if the alpha version does not work on your system and does not bring the expected results. 

MIB Importer 2.1 Stable (1.2 MB)

Legacy Version

This version is intended for PRTG 6. Support has ended for this version. Please switch to the current PRTG version.

MIB Importer 1.3b Legacy (1.7 MB)

Import of SNMP-MIB files into Paessler Monitoring Applications

Many network devices and programs come with so-called MIB files that describe the parameters and readings which are available for monitoring via SNMP. With MIB Importer you can import these MIB files (supplied by the vendor of your devices) and convert them into OID libraries for PRTG Network Monitor. Then you can easily setup SNMP Library sensors using the new OIDlib files.

A Few Words About MIB Files

MIB files are hardware and operating system independent information files that tell network manangement systems how to retrieve in-depth data using the SNMP protocol from network devices like routers, switches, network printers, disk arrays (even air conditioners) as well as many server software products (database servers etc.). MIB files describe the available readings in tables, values, registers using a special text format (Abstract Syntax Notation One ASN.1).





Because MIB files are written in this highly abstract definition language, they need to be translated into a more software compliant form so that PRTG can work fast and seamless with the data. This is the task of the MIB-Importer which translates MIB files into Paessler's XML-based OID-Library format.

MIB files are usually provided by the manufacturers of network devices and services (e.g. Cisco MIBs can be found here). Please visit your vendor's website or contact their support to get the MIB file for your specific device.



This program is provided as a freeware and thus for free for Paessler customers, mainly as an add-on for PRTG. Please understand that we cannot provide deep support for this program.
