Network Troubleshooting with iTrinegy AppQoS Portable

The iTrinegy AppQoS Portable (formerly Itheon Portable Network Consultant or PNC) is the perfect tool for rapidly identifying the causes of poor application performance. Simply connect AppQoS Portable into any network segment and, with no configuration, you will have concise, organized and easy-to-understand views of key network activity data and application use of the network within minutes!

AppQoS rapidly delivers information regarding application response times, transfer rates, bandwidth usage, etc, from a high level ‘satellite’ (or 20,000 feet) perspective rather than in the microscopic detail typically delivered by conventional network protocol analyzers or “sniffers”.

AppQoS will monitor any application but can provide particularly detailed analysis for:

Windows Network Monitoring
VoIP Monitoring
Web (http) Monitoring

Windows Networking Monitoring

When a user accesses the Windows Network there are times when log-on is slow, performance is poor or it simply does not allow access at all. With AppQoS Portable diagnosing Microsoft network performance problems and exposing the issues that can affect performance, it makes it easy to ascertain what’s going on.

AppQoS captures:

Which servers were used to log on
The log on times
What files have been opened
How long it took to open the file
How many bytes were transferred
Who opened the file
How many times a particular file is requested
What the file type is i.e. .docs, .exe, .PDF, etc

The Tree Drill-Down navigation can quickly pin down background applications accessing file shares including products such as Google Picasa or Sophos.

AppQoS Portable also allows for housekeeping such as:

Re-organizing files that are frequently used
Understanding if a file server is under pressure and whether balancing the load by moving applications to another server will alleviate the problem.

VoIP Applications Monitoring

The AppQoS module for VoIP will allow an organization to have more relevant information on not only the status of the call but also show:

Phone numbers visibility - who is calling who, telephone numbers etc.
How long it took to set-up the call and if the call wasn’t set up properly then why?
What happened during the call
Report on long calls, time, amount of data sent, jitter, loss
Top callers etc

Web (http) Monitoring

The AppQoS module for http enables you to:

Monitor each ‘get’ request to track the times it took to download each page, graphic image, or other object
Enable the web site manager to figure out why something is going slow
Monitor all this over time – allowing trend analysis
Determine, if a user says they got a poor experience, why?
Optimize response times on certain important pages etc.
Monitor background traffic to determine its impact on the http

"AppQoS proves that you don't need a degree to monitor and analyse network and application performance. It works straight out of the box and is capable of providing a truly remarkable amount of information about network utilization
