Choosing between Standard Traffic, SNMP Helper, Library, or Custom SNMP Sensors
PRTG Traffic Grapher offers 4 different types of SNMP sensors:
· Standard Traffic sensors: This is the most common usage of SNMP. Via the MIB-2 standard PRTG can access the traffic counters of a device to monitor its bandwidth.
· SNMP Helper sensors: Paessler SNMP Helper is a system-level software program that runs on a Windows 2000, XP, or 2003 computer system that allows OTHER systems running PRTG Traffic Grapher to collect performance information remotely for several thousand Windows Performance Counters, using the SNMP protocol. See the section Paessler SNMP Helper for more details.
· OID/MIB Library sensors: PRTG comes with several preconfigured libraries (so called “OIDLIBs”) for various device types that helps you to monitor CPU loads, disk usage, or temperatures. Additionally you can convert most MIB files from device vendors into OIDLIBs using Paessler’s MIB Import Tool to create many more sensors. See the section Importing MIBs using Paessler MIB Importer and Converter for more details.
· Custom SNMP sensors: Choose this type if you want to monitor an SNMP OID value that PRTG does not have built into its libraries. You must supply the OID value for the reading you want to monitor.
