Traffic management becomes critical as your network
infrastructure expands to support different types of traffic and
users. Most traffic management solutions have serious
limitations: too expensive, difficult to use, and overly taxing
on bandwidth. However ProCurve Networking by HP addresses these
requirements, overcomes the limitations of other solutions, and
gives you valuable insight into LAN performance. Click here to

Today's focus:

Coradiant provides insight on Web performance

By Thomas Powell

Many Web administrators live in a state of blissful ignorance,
unaware of the true health and performance of a Web site until
users complain. Coradiant's TrueSight 1100 appliance actively
monitors actual Web site traffic, giving Web managers a heads-up
on problems before their users do.

The TrueSight device needs to be strategically installed in the
delivery network to capture the appropriate data. This data
capture is accomplished via a network tap, a mirrored port on a
switch, or similar feature on a load-balancing device. We were
disappointed the device did not contain its own network tap for
easy installation.

Initial setup -- done with a command line interface via a serial
connection -- is minimal and requires basic network settings,
port information to later administer the box via Web interface,
and a master security officer password for the box. In spite of
a relatively secure security posture of the appliance in
general, you can set a relatively weak password here.

The Web interface lets you enable the device to begin logging
traffic. Data collected can be downloaded to a local system for
offline analysis or sent via SNMP to any monitoring system.
Various session and user detection parameters can be set so
captured traffic can be reassembled into a logical view of user
activity. To do this you need to make sure your sites have
distinguishing items to easily identify users.

However, because you might not always be fully aware of the
range of changes in monitored Web applications, it would be
helpful for the device to monitor traffic for new
session-oriented cookies and URL patterns, and to alert you to
apply them. If you are going to monitor static Web sites, you
have to rely on timing and IP addresses to identify user
patterns.

IS IT THE NETWORK OR THE STORAGE THAT'S THE PROBLEM?

Midsize and larger businesses often find their IT topology has
become a complex mix of servers, networks and storage systems.
Many of these companies also route long-haul traffic over
fiber-based networks - metropolitan-area networks, WANs and
private optical networks. Who's responsible when a
storage-related problem occurs on a fiber network? For more,
