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.

Network monitoring: PRTG is...
Comprehensive
With PRTG, you can monitor your entire network. Servers, routers, switches, traffic, cloud applications... PRTG lets you keep an eye on everything.
Easy-to-use
250+ preconfigured sensors help you to quickly set up your network monitoring. You can switch from another tool such as Nagios with little to no effort at all.
Transparent
PRTG is all-inclusive. Upon purchasing a license, you’ll get access to all PRTG features, including the alarm system, technical support, and the full range of sensors.
Effective
PRTG is used by more than 500,000 administrators worldwide, all industries included. Even system administrators in charge of critical and highly-sensitive IT infrastructures put their trust in PRTG. A few case studies
Customizable
Feel free to customize your PRTG environment – in accordance with the number of sensors you need. The first 100 sensors are free and never expire. You can therefore get a feel for PRTG with no pressure whatsoever.
Tutorial: Opening an MIB file
Search for the MIB file on the website of the manufacturer of your network device (router, switch, server).
Download and install the Paessler MIB Importer.
Launch the program.
Choose the menu item “File | Import MIB File…” to load and convert the MIB file.
You may encounter an error during the import, in which case you will have to edit
the MIB file.
Check the values that are displayed after the import.
If everything is OK, then select the menu item “File | Save For PRTG Network Monitor” to save the new .oidlib file.
If necessary, save a copy of the file in the /snmplib subdirectory of PRTG.
Create the SNMP Library sensors and select the desired entries that are made available by the new .oidlib file.
Unlimited use of PRTG for 30 days. After 30 days PRTG reverts to the freeware edition.

Definitions:
MIB, MIB Files, OID, IETF
MIB
MIB stands for “management information base.” An MIB contains information that is used to monitor and control a network device. Generally speaking, an MIB is a collection of definitions which are stored in devices as management information.
MIB file
An MIB file is a file that contains the corresponding management information for a specific device. SNMP is used for this function.
OID
The various bits of management information are called "managed objects.” Each object has its own OID (object identifier). An OID is a series of numbers which makes the designation of each object unique. These numbers are read by SNMP and displayed in PRTG.
MIB tool
Many administrators want to know how to read, import, and convert MIB files. There are a number of MIB tools and MIB browsers on the market. Paessler AG also offers a free MIB importer which you can use to convert your MIB files.
IETF standards
The IETF has defined a global MIB in RFC 1155. MIBs are included in more than 300 of the IETF’s first 5,000 RFCs. For an initial overview, check out this Wikipedia article.
Manufacturer MIB files
Manufacturers and MIBs
Most manufacturers – including Cisco, Juniper, Dell, etc. – offer SNMP or other technologies (such as Net Flow) for their routers, switches, and workstations. But as there are countless different manufacturers, it is impossible for monitoring software to provide standard sensors for every situation or for every piece of hardware that exists on the market. This is where MIB files come into play.
Finding an MIB file
MIBs can be found on the websites of manufacturers (usually in the download section), or on the website of the hardware you wish to monitor.
Practical tip: Hey Luciano, how can I read the OIDs that are displayed in an SNMP table?
“Monitoring objects in table form can be extremely taxing. We’ve developed the SNMP Custom Table Sensor to speed up the process. This sensor uses a meta-scan to identify the table, and then displays the table in PRTG. See the following Knowledge Base article for more information on how to configure this sensor.”
Luciano Lingnau works in the Paessler AG Technical Support Department.
