What's New in this Release?


The latest release of NetFlow Analyzer (7.5) can be downloaded from the website at http://www.netflowanalyzer.com/download.html


New Features in Release 7.5

Feature Description
Customizable dashboard Users can create dashboard by placing the widgets as per their requirements. This enables easy understanding of the network behaviour in one glance
GRE application filter

Applying this filter in any cryptomap tunnel prevents the GRE traffic getting double counted. Otherwise, the cryptomap interface in which NetFlow is enabled double counts the GRE traffic.

Support for MSSQL database NetFlow Analyzer now supports MSSQL Database also.
Email option for sending reports This option allows the user to send a screenshot of a page to a particular mail ID
DSCP names in alerts and IP groups Now, an user can set alerts based on the DSCP names and also create IP groups to monitor application using particular DSCP names.
Volume based billing The next level of billing is here, after usage based billing. Users can generate bills based on the volume of data.
Site-to-site traffic monitoring Users can create groups for monitoring site-to-site traffic.
Secondary DNS server lookup This allows the system to go through DNS servers other than primary ones for resolving DNS names.
Raw data storage For users who do not need an in depth report and for whom storing large data is an issue, you can now store the raw data for as less as 1 hour.

New Features in Release 7.0

Feature Description
Reporting on Cisco CBQoS Useful for monitoring class based pre and post policy traffic usage, class based drops and queuing
Authentication using radius server Useful for centralzed controlling of access to resources in a network by a single global set of credentials
Ability to create IP groups with exclude IP address option One could bulk load IP groups and selectively remove unwanted IP groups
DNS resolving enhancement of source and destination addresses Faster retrieval of DNS names made possible
Support for user configurable DNS names for IP addresses Customizable DNS names helps in easier management of the network
Usage based billing Generation of periodic bills for accounting and for charge-back.
Reporting on source network and destination network This allows the user to view the source networks, destination networks and conversation between them.
Different IN and OUT speed can be configured for interfaces Helps in setting appropriate speed for IN and OUT interfaces
Support for exporting reports to CSV Helps in easier maintenance of data for historical reporting besides the flexibility to import in XLS sheets for any analyzis
Sorting on the Autonomous Systems view for easier tracking and for peering arrangement Ability to group together applications into a single logical entity
Option to exclude ESP_App on user defined interfaces Ensures that traffic is not double counted in case of ESP tunnels.
Option to suppress output interface accounting on user defined interfaces Useful when working with WAN accelarators
Quick view traffic graph in Dashboard view Offers Enhanced usability
Graphs enhanced to one min granularity and also to real-time in Network Snapshot Offers a more realistic reporting of the network health for quicker action to avoid any network eventuality
Ability to set snmp parameters globally for all routers Offers the flexibility to avoid havign to set the same SNMP parameters on each individual router
Support for sorting of interfaces based on usage in Dashboard View Helps in easier viewing of interfaces based on maximum/minimum bandwidth usage and for appropriate action
User management enhanced to provide last login time and current login status for all users Helps individual users to quickly confirm that one's login credentials have not been compromised
Support for configuring alerts on interface groups. Interface groups can be used for checking the router traffic (by combining all the interfaces into a single group)
User permission can be granted at a interface group level. This feature would enable providing permission at an interface level while creating a user.
Look and feel changed The user interface has been changed for a better user experience
Localization supported NetFlow Analyzer supports French, German, Chinese and Japanese.
