Managing a Corporate network spread across the globe is a highly challenging task for the Network Administrator. When it comes to bandwidth monitoring and generating traffic reports for each location, based on their time zone is a painful task faced by every network admin. Of course there will be localizations within the network with individual Administrator’s across the globe to monitor their own segment of the network.
NetFlow Analyzer Enterprise Edition with distributed Architecture serves many corporate networks to successfully manage bandwidth and monitor traffic through their network devices. This blog focuses on the Enterprise Edition of NetFlow Analyzer and its time zone based traffic report generation feature.
NetFlow Analyzer Enterprise Edition Architecture:
This edition has a distributed architecture where flow collection is done by collectors and a central server does all the reporting. The collectors send collected NetFlow data over HTTPS to the central server for storage and reporting. Advantage of using NetFlow Analyzer Enterprise Edition is:
· Suited for large enterprises which monitor more than 600 interfaces
· Highly scalable
· Distributed monitoring: monitor across-the-globe offices from one location
Consider a network which spread globally accross 4 location and using NetFlow Analyzer Enterprise Edition to monitor the bandiwdth. The have office in (Japan, China, India and US). The central reporting server is installed on the Head Office in (US), collectors are deployed on each locations respectively which collects the NetFlow data exported from devices, sends collected NetFlow data over HTTPS to the central server for storage and reporting. Each collectors from these locations are reported with their respective devices in NetFlow Central Reporting server.
How to view Time Zone based reports:-
Assuming that the Network Administrator in the US manages all other locations including the Head Quarters, his job is to monitor the entire network with the help of administrators at each location. The role of administrators at each location is to manage and monitor devices that belongs to their location. Since these administrators are located in various time zone, it would be better if the reports generated from NetFlow Analyzer are with their respective time zones.
Device Grouping :-
The Administrator in US managing the entire network and central reporting server, creates a device group for all the three location and associated the Devices that belong to each location to the concerned device group. Device Group can be found under Admin Operations in Central Reporting server.
User Creation :-
He then created a user access(Operator Lelvel) for each location administrator with their respective time zones and associated the device group that belongs to them. User Management can be found under Admin Operations in Central Reporting server.
Once the users are created, each location users can log in to Central Reporting server and generate reports based on their time zone. Users can generate reports for their devices alone. They can also create Alerts for the devices being monitored.So, when threshold violation occurs they will get an alert.
Administrator can also change their time zone, when generating report for device located in different time zones. Time Zone settings are available under Admin Operations.
With this Time Zone based reporting feature, Managing network spread across the globe becomes much easier.
