NetForecast Best Practices Study 

NetForecast's APM best practices benchmarking survey definitively 

shows that good APM processes deliver results… 

Source: NetForecast Survey of 364 IT managers 

http://www.networkworld.com/community/appview 


5 

The Value of Best Practices 

Enterprises with a benchmark score above six really do deliver better 

performance for their users – 75% better performance 

Source: NetForecast Survey of 364 IT managers – 


• Experience 75% fewer 

critical application problems 

• 75% more likely to learn 

about performance problems 

proactively rather than 

reactively by users calling 

the help desk 

• Typically spend 4 hours to 

resolve performance 

problems, compared to 16 

hours for their low-scoring 

counterparts 


6 

Simplifying The Tool Universe 

Improves Outcomes… 

“To ensure optimal performance you need two tools – one for monitoring infrastructure 

performance and another for monitoring application performance. The resulting 

stereoscopic view ensures that you are able to solve more problems faster.” 

Source: NetForecast Survey of 364 IT managers – 


• Scores improve with the 

number of vendors 

deployed up to three 

• Among the very highest 

performing enterprises the 

vendor count dips 

precipitously 

• The highest-performing 

enterprises get good results 

with fewer vendors because 

they have very effective 

APM processes 


7 

Which Vendors Ranked as Most Used? 

“71% of the topperforming 

enterprises 

use NetScout's 

performance 

management tools” 

NetForecast – 

June, 2011 

NetForecast's APM 

benchmarking survey 

results show that 

NetScout is the 

vendor most 

frequently used by the 

top-performing group.

The Evolution of

Managing User Experience 

Monitor 

Networks 

User Experience 

“Most IT groups monitor key network and system 

components, but a lack of visibility into the end-to-end 

health of applications often results in IT managers 

spending too much time trying to isolate problems. 

Meanwhile, users are frustrated, the organization’s 

mission is suffering and revenue is being lost.” 

InfoWorld – APM Report 

or 

Monitor 

Applications 

“End-user experience monitoring will shift 

from a focus on the performance of 

individual applications to a focus on enduser 

behaviors and interactions with the 

application portfolio as a whole.” 

Gartner – January, 2011

Current UC Service Management 

Approaches Aren’t Enough… 

• Vendor tools focus on own technologies 

• Vendor-specific tools don’t identify 

underlying performance issues 

• No integrated voice, video and data 

service delivery management 

• Most solutions focused on networks 

• Need common tools for diverse 

IT teams and skills

nGenius InfiniStream Appliance 

• Single nGenius InfiniStream appliance* will support BOTH UC 

and data traffic monitoring from same device 

No additional license cost for nGenius InfiniStream to support Voice | Video 

• UC monitoring will likely require additional instrumentation points 

On average 20-30% cross-leverage existing data sources
