Hi All, I would like to know if Netflow Analyzer 7.0 can run on a Virtual Machine (i.e running in physical ESX Servers). If yes what specifications should the virtual machine has. Thanks Regards Thierry Mohamudally
Netflow Analyzer 7 Professional Windows 2003 Process and useraccount
We have a Professional version of ManageEngine Netflow Analyzer running on Windows 2003 R2 SP2. Need some information regarding the netflow service processes. What is the process/image name(s) for the netflow service/collector? What windows account does the netflow service/collector run under? We have also moved our Netflow Analyzer installation to a new server recently and have an issue when the licence file was applied to the new installation. The licence should be for 20 interfaces but when we
Not seeing any utilization statistics from netflow data off of Cisco ASA
I am albe to get the netflow data into Netflow analyzer from a Cisco ASA 5520, but no information regarding bandwidth utilization is showing. Any Suggestions?
Identifying internal hosts
I am hoping for a little help either understanding or refining my use of NetFlow Analyzer. We currrently use a small Cisco 800 series router for NetFlow analysis, so the setup of the network looks like: NetFlow Analyzer Server <--> LAN <--> Cisco 870 <--> Pix <--> Internet Router This seems like a normal setup for our specific analysis, as the Cisco router captures traffic on its internal interface (termed Vlan1) as well as its external interface. Ideally, I feel like this should let us have
NFA 7.5 new install won't start?
Seems like this is echos of the old problem where one would have to modify a config file taking out 'localhost' and putting in '127.0.0.1' before NFA would run. I've dug around in the XML for the system and I can't figure out what is wrong here - any suggestions? First time service startup takes longer time than usual Server is starting. This may take a couple of minutes ... This evaluation copy is valid for 29 days Could not create connection; - nested throwable: (java.sql.SQLException: null,
Centos5 Supported?
Can we install Netflow Analyzer 7.5 on a Centos5 box?

Netflow for traffic metering
Hi, I've downloaded the ManageEngine Netflow Analyzer to try it out. I'm looking for a feature which would give me a report on which IP address exceeded a given in+out traffic limit in a given time period? This is such that we can bill our customers who exceed their traffic quota. Is there anyway to get this report for your Netflow Analyzer? I've had a look at the reports, they are very good but I'm not able to find this filter. Thanks, Chaminda

Billing Reports
We would like to bill our individual departments base on usage at our core but can't seem to figure out how view consumption for a network on an interface. For example: on gig1 view total bandwidth used by 192.168.1.0/24 and on gig1 view total bandwidth used by 192.168.200.0/24 thanks
Netflow Analyzer 7 to 7.5?
We owned Version 7. Is it possible to upgrade to 7.5? Will our license be good for 7.5? Do i need to do a fresh install? Please let me know Thanks, Zeek
Live reports?
Is there an option for live graphs and stats? I believe Opmanager has this feature, but it's very limited.
Summary reporting???
Has anyone been able to create a monthly report that will summarize all ip gorups and show the percentage of total bandwidth used? Ex. Group 1 used 90% of total bandwidth Group 2 used 5% Group 3 used 3% Group 4 used 2%
Fresh install of NFA 7.5 can't access SQL server?
I get this when I try to start a brand new instance of NFA 7.5. I recall having problems like this long ago running NFA on SuSe and needing to edit an XML file to change references from 'localhost' to '127.0.0.1'. This seems maybe similar, but I've been digging and can't find the place to force it to use localhost instead of the outside IP. FYI I'm evaluating OpManager and I'm seeing similar problems there. First time service startup takes longer time than usual Server is starting. This may take

Billing
We are providing billing to different departments and have several Internet links. We would like to run reports based on Networks on each of these interfaces. For example: on gig1, 192.168.1.0/24 transferred 50gb of data over X amount of time also on gig1, 192.168.200.0/25 transferred 10gb of data over X amount of time. Is this possible? I see where you can setup billing, but I cannot figure out how to run these reports manually or how to view aggregate bandwidth consumption on a particular interface
Netflow not picking up interface
Hello, I have recently moved a circuit from one interface to another on a Cisco 7200 router, previously the interface has been monitored but due to this move I have removed the license. After configuring the new interface on the router to send information to the netflow analyser the interface does not appear at all.

Failover in NetFlow Analyzer Enterprise edition
With the Failover feature, one central server acts as a Primary server which is used for reporting, configuring alerts, IP groups and other functionalities. A second server, which is the HotStandby Server, does data and configuration replication from the Primary server. This also acts as a mechanism for data backup without shut down of the Primary Server. Whenever there is a database update or configuration change in the Primary central server, the updates and changes will be automatically updated
Some interfaces show in and out while others only one.
I have attached a JPEG showing this but some interfaces will agergate the traffic and show both in and out while others will only show out traffic. The top one "capstone" is a multilink that shows both in and out traffic. While Guaranteed is two serial connections and it only shows out traffic. What signifies if a interface will show in and out or just one? Thanks, Josh

AS Traffic Reports laggy
Hi to all, I'm testing Netflow Analyzer 7 on my network and all features work great except for the AS collection. When I turn this feature on and surfing on the AS report page, my browser is taking 100% CPU for a long time before displaying the results. The server is not showing any particuliar activity however... Due to this problem, the use of this feature is completely impossible (I must kill my browser on third of my attempts to get an AS report). I tried IE7 & Firefox, tried on a "big sized"

What impact does Netflow data have on a heavily utilised link
Hi, I have a link that is heavily utilised and I want to find out which applications are generating most traffic. However I am concerned that if I start exporting Netflow data then this will make the link worse. Are there any stats as to how much bandwidth Netflow data consumes on a WAN link? Thanks
Speeds graphed and shown not correct.
I am seeing what looks to be an SNMP issue. The usage on ports that are doing more than 120Mbps shows as 356K which tells me that the counters are rolling over. Is there a way to tell is this is using 64bit counters?
