NARRATIVE:
Connie Logg joined SLAC in July 1971. In 1991 she joined the SLAC Computing Services department,
and started working on network monitoring. In 1992-93, she was responsible for the development of the
first network monitoring presentation system based on the World Wide Web. The components of this
system included SNMP monitoring of all of SLAC’s network support equipment as well as the network
connectivity monitoring of SLAC’s world wide collaborators via Ping. In addition, she is responsible for
SLAC’s daily Netflow analysis. Over the past 4 years, she has been the primary architect and implementer
for the IEPM-BW bandwidth measurement and monitoring system which is deployed at several sites
around the world.
