Say that 3 times fast… Network World’s Debbie Dubie’s article on “How to troubleshoot sluggish apps” talks about how poor performing applications has affected overall corporate revenue by as much as 9% (according to a survey conducted by Aberdeen Group).  She looks at 3 scenarios where application-performance problems can impact business productivity and profits.

One of the scenarios is poor quality of VoIP calls.  Debbie interviewed Koie Smith, an IT administrator at Jackson, Tenn., law firm Rainey, Kizer, Reviere & Bell.  Koie noticed that calls were performing poorly across the network and tried to trace it to a port on his switch.  He then looked at his QoS settings and discovered “Undefined” priority tags on his voice traffic.  Rather than going through all of the above steps to determine that his QoS priority tags were not set correctly, Koie could have identified the problem faster by simply looking at the VoIP Expert Analysis screen of the Network Instruments Observer.  The Observer provides visibility into the VoIP traffic while expert analyzing the information to quickly resolve issues.  The VoIP Experts immediately flag problems such as unacceptable jitter levels, lost packets and alterations in the QoS stream.  The Observer also tracks VoIP and overall network performance and can identify whether the jitter or delay is caused by other applications on the network.
