Nuremberg, Germany-based Paessler AG, which has had a sizable customer base in North
America for its PRTG Network Monitor software, has gotten with the times and added to its
latest version (version 7.2) new modules for monitoring the health and performance of IP

North America, who filled us in on the basic product architecture:

on a server, and then we have a local probe attached to that server for monitoring the
network that that server’s attached to.”

monitoring, using what Paessler calls ‘sensors.’ The probes collect data from the various
network devices and forward it to the core engine, via secure SSL.

and other networking infrastructure, sensors for monitoring servers-including POP, IMAP,
and Exchange mail servers-even sensors that function in virtual environments, such as
