nefu - A network monitoring daemon.

nefu monitors network services and reports outages. Working from a discription of the network topography, nefu's algorithm prevents "false alarms" in the event of a network outage due to a dependency failure.

Supported Platforms

nefu has been successfully compiled and tested on the following platforms:

  • Solaris
  • Mac OS X
  • FreeBSD
  • OpenBSD
  • Linux
  • Debian
nefu is in production use at the University of Michigan, monitoring more than 250 servers (among which are U-M's IMAP, WWW, and LDAP Directory servers) and a variety of other systems. nefu is available under a BSD-style license.

For information on the University's use of nefu, please write to nefu@umich.edu.
