Paessler SNMP Tester by Paessler GmbH

With Paessler SNMP Tester you can run simple SNMP requests against a device in your network. During the test each single step of the SNMP request is logged into a logfile for analysis. The idea of this free program is to debug SNMP requests down to the protocol level in order to find communication and/or data problems in SNMP monitoring configurations.

Paessler Netflow Tester by Paessler GmbH

Paessler Netflow Tester dumps the data of all Netflow packets that a computer receives from a Cisco router. This can be useful when debugging bandwidth monitoring configurations based on Cisco's Netflow protocol. First the Netflow protocol must be enabled and configured on the router. Then the router must be given the IP address of the computer running Netflow tester so that the UDP data packets with Netflow data are sent to that computer.

Paessler NetFlow Generator by Paessler GmbH

Netflow Generator creates artificial NetFlow Version 5 data streams without the need for NetFlow compatible hardware. It is the perfect tool for testing the NetFlow functionality of PRTG or other NetFlow compatible programs. NetFlow Generator sends NetFlow 5 Packets to a specific target computer which processes the data. While the simulator is active it will create NetFlow packets which contain information about the selected traffic pattern.
