Subject: Network/Systems Management - Taking event correlation seriously
Today's focus: Taking event correlation seriously
-------------------------------------------------
By Dennis Drogseth
There has been a lot of attention placed upon event correlation in the
last year - by the industry, by some users and, admittedly, by this
column. A string of recent news over the last few months has
heightened this attention: Visual Networks just announced plans to buy
Avesta; Micromuse announced plans to acquire Calvin Alexander; Tavve
introduced e-probes; and RiverSoft introduced the concept of a
"network management operating system."
Event correlation reduces alarms and identifies points of failure across
networks, systems and (more rarely) applications. Because these
functions are so useful, the recent attention shouldn't come as too
much of a shock.
Between 60% and 90% of the time IT managers spend resolving problems is
lost to diagnostics. Event correlation promises to significantly
reduce that percentage - bringing down operational costs for IT, and
reducingrevenue lost to downtime by many millions of dollars for large
businesses. Also, a correlated knowledge base can improve accuracy and
efficiency for other applications, such as those targeted at trending,
performance and service-level management. In the most intricate of
examples, information from a correlated, self-adaptive knowledge base
can inform such actions as software distribution, configuration and
change management - pushing towards pretty much the whole range of
management disciplines.
On the other hand, most users still don't have great confidence that
event correlation - and its more mystical twin, "root cause analysis"
- actually work. Rules-based approaches - in which armies of
well-meaning specialists camp out to map IT eccentricities to a set of
raw abstractions - haven't really caught on. More automated approaches
have their apostles in the market, but many users still remain
restless, skeptical and unsatisfied.
No one, not even the marketing wing of the most optimistic
event-correlation vendor, claims total victory - so they're not 100%
disconnected from enterprise network managers. But they're close.
"Automated" solutions often just aren't that automated. Pinpoint
accuracy can turn out to be more like barn-door target shooting.
Costs are another factor. If a platform costs $15,000, and a
third-party event-correlation solution that inhabits it costs $150,000
- which is the more strategic investment?
This time, we are seeking your ideas. Are you among the skeptical and
the disaffected? Or are you an enthusiast? Why? The survey can be
reached online by going to the Enterprise Management Associates home
page (http://www.enterprisemanagement.com), or by clicking here:

The survey should take about five minutes - 14 multiple-choice
questions. It will run for six weeks. After that, of course, I'll
write a newsletter looking at the results. If you're frustrated, it's
a chance to strike back. If you're a fan, it's a chance to vote. I
also invite your comments via e-mail.
