The Value of Best Practices<br />
Enterprises With a Benchmark Score Above 6 Really Do Deliver<br />
Better Performance for Their Users – 75% Better Performance<br />
Source: June, 2011 NetForecast Survey of 364 IT managers –<br />
http://www.networkworld.com/community/appview<br />
• Experience 75% fewer<br />
critical application problems<br />
• 75% more likely to learn<br />
about performance problems<br />
proactively rather than<br />
reactively by <strong>user</strong>s calling<br />
the help desk<br />
• Typically spend 4 hours to<br />
resolve performance<br />
problems, compared to 16<br />
hours for their low-scoring<br />
counterparts<br />

Simplifying The Tool Universe<br />
Improves Outcomes…<br />
• Scores improve with the<br />
number of vendors<br />
deployed up to three<br />
• Among the very highest<br />
performing enterprises the<br />
vendor count dips<br />
precipitously<br />
• The highest-performing<br />
enterprises get good results<br />
with fewer vendors because<br />
they have very effective<br />
APM processes<br />
“To ensure optimal performance you need two tools – one for monitoring infrastructure<br />
performance and another for monitoring application performance. The resulting<br />
stereoscopic view ensures that you are able to solve more problems faster.”<br />

Service Management Challenges<br />
No Problem<br />
Prediction<br />
Unable to identify<br />
problems before<br />
<strong>user</strong>s impacted<br />
• Ineffective insight into<br />
emerging performance<br />
problems and security risks<br />
• Users’ calls to help desk<br />
triggers reaction<br />
• Lack of unified end-to-end<br />
visibility of business services<br />
and service levels<br />
No Effective<br />
Triage<br />
50% to 60%<br />
resources wasted<br />
chasing problems<br />
• Common “rule-out” practices<br />
for incidents means too many<br />
IT staff are consumed to solve<br />
problems<br />
• Difficult to identify root cause<br />
across service domains<br />
• Support people are too busy<br />
putting out fires<br />
No Effective<br />
Diagnosis<br />
Performance<br />
problem diagnosis<br />
can take days<br />
• Organization misaligned to<br />
support end-to-end issues<br />
• Issues are diagnosed<br />
independently in technology<br />
silos<br />
• Locating and identifying<br />
precise root cause is were<br />
most time is lost<br />

Why Network Monitoring Switches<br />
• Multiple IT groups need access to<br />
packet-flow data<br />
Performance management, unified<br />
communications monitoring, compliance,<br />
cybersecurity …<br />
• Limited network connection points<br />
Segment-specific taps<br />
SPAN/Mirror ports<br />
• Different tools need different levels of<br />
data/traffic<br />
• Growing mismatch in network speeds to<br />
tool connection/capacity<br />
• Need to support on-demand hot-spot<br />
analysis<br />

The Value of a Single Vendor<br />
• Single-vendor solution with one<br />
buying relationship<br />
• Fewer vendors to manage and<br />
devices to integrate<br />
• Simplify architectural complexity and<br />
maintain control of network access<br />
• Pre-integrated and tested minimize<br />
interoperability issues<br />
• Stre<strong>am</strong>lined support and<br />
maintenance<br />
• Lower capex and opex results in a<br />
lower overall total cost of ownership<br />
