INSIGHT ON WEB PERFORMANCE
Many Web administrators live in a state of blissful ignorance,
unaware of the true health and performance of a Web site until
users complain. Network World's latest Clear Choice Test
reviews an appliance that actively monitors actual Web site
traffic, giving Web managers a heads-up on problems before their
users do. For more, click here:

Today's focus: Network Physics helps to provide best practices
for how to respond to an event
By Denise Dubie
Best practices seem to be on the mind of most IT professionals
these days
<http://www.networkworld.com/research/2005/011005cobit.html?rl>.
Ad hoc firefighting and troubleshooting practices are no longer
acceptable as regulatory and security concerns mount within
enterprise IT shops. Now network managers need to be sure to
follow procedures and document processes, while also ensuring
performance across their networks as well as the systems and
applications the network supports.
Network Physics next week is set to announce an upgraded version
of its NetSensory operation system (which I mentioned in this
newsletter a year ago <http://www.networkworld.com/nlnetop7864>
). NetSentry 5.0 will run on the company's NP-500, NP-2000 and
NP-Director appliances and adds what the company is calling
Insights, which are XML templates that encapsulate best
practices for how to respond to an event or problem within
networks, applications and systems.
"Insights provide network managers with a step-by-step workflow
and best practice approach to resolving problems or even
responding to network changes," says Dwight Barker, director of
product management at Network Physics.
Insights could help junior network staff members resolve
higher-level issues as well. NetSentry is typically aimed at
senior network engineers who know what they are looking for when
sorting through performance data from network devices, systems
and applications. The Insights feature could walk
less-experienced staffers through resolution, the company says.
The NetSensory operating system facilitates communication among
multiple NP-Director and NP-2000 boxes. The NP-Director,
launched in September 2004
<http://www.networkworld.com/nlnetop7631>, is a central
appliance that sits in a data center and provides a global view
of a network.
The NP-2000s are 1U devices that plug into a network via a
switch port and passively watch all the traffic at key
aggregation points. The boxes can auto-discover paths for each
application flow in a network, determining performance metrics
such as packet loss, throughput, network latency and server
response times. IT managers can use the information to
troubleshoot problems locally, but because the boxes also
forward information back to NP-Director, central data center
managers can determine whether a problem, such as increased WAN
latency, is widespread.
Because of this architecture, the company says NetSensory 5.0
coupled with the company's appliances can help IT managers using
WAN optimization tools determine the true source of performance
issues. Because 80% of the company's 150 or so customer are
currently using WAN optimization tools
<http://www.networkworld.com/nlnetop7160>, Network Physics'
officials say their products can accurately pinpoint if a server
is causing poor performance or if an application is the source
of concern or if more bandwidth is needed.
"The products can tell if an application is chatty, if there are
latency issues, basically if the other vendors' products are
working appropriately for the customer," says Bob Quillin, vice
president of marketing at Network Physics. "It's an objective
measure of performance."

IT PROS SHARE THEIR TALES OF MAKING ITIL WORK
Running an enterprise network is challenging. IT organizational
change can be even more so if managers don't balance efforts
proportionally across people, process and technology.
Implementing best practices frameworks such as Information
Technology Infrastructure Library (ITIL) can help, but they
introduce their own set of challenges. Click here for more:
