DESCRIPTION
This slide deck takes a look at the results from a recent network monitoring survey carried out by NetFort. The increased use of external SAAS and cloud based services; consolidation of servers into fewer data centres is driving demand for deeper insight into bandwidth consumption, especially on critical links. However, the number of applications in use on networks today and increased use of CDNs (Content Distribution Networks) makes it very difficult to see clearly what is happening and making life very difficult for network managers. NetFort LANGuardian is deep packet inspection software for investigating, monitoring, and reporting on network activity. LANGuardian helps network administrators to: - Classify network traffic by application and by user - Troubleshoot bandwidth issues right across the network - Perform network or user forensics on past events - Investigate activity on Windows file shares, - Keep track of user activity on the Internet.

Survey Highlights• 76% of respondents already use network
monitoring tools.• Most important feature not provided by
existing tools:– Ability to break down traffic by application and user
• Reports most often requested by management:– Information on bandwidth consumption
• 71% respondents think it is a necessity to associate network activity with usernames and not just IP addresses.

Importance of usernames in reportsDo you think associating network activity, including bandwidth, traffic, Internet usage with IP address and username is a necessity or just nice to have
www.netfort.comSlide 13
Respondent commentsWe can better understand true bandwidth needs if we can identify the bandwidth hogs.
Being able to not only simultaneously monitor each computer a student is on but to also be able to monitor everything they did on that computer, I feel would prevent students from going to sites (by hacking) that are not appropriate.
On several occasions I have wished I had a tool which would easily show me all the traffic coming to a particular IP, with source IP and packet contents.
IP addresses change. Associating activity with a user (or a user's system) is most helpful.
Required to verify problems.
