Database Type and Structure
Currently we are thinking of doing an automated report that regularly compiles a selected reported for an interval of lets say a month. Is there any way for us to do this automatically? Other option that we've been thinking is basically to get import the database from the netflow server than compile the report ourselves. Just wondering what type of database and structure is the netflow using.
Use external Database?
HI @all, is there now a possibility to use an external database server? Cause we have an high performance Mysql cluster which would be the best to use with the NetFlow Analyser. Thanks, Globe

Hi I am a new user of Netflow Analyzer Enterprise version 6. I have been using this for about 6 months now. I would like to make the below recommendations. 1) Hierarchical views, the ability to nest device/ip groups.

Does NetFlow Analyzer v6.1 support netflow collection from more that 5 routing devices given that is the limit on the number of listeners that can be configured?
Matching packet counts on the line between two interfaces
Folks, I am monitoring a both interfaces on a T3, and one thing I noticed was that data transfers/packet counts for a given flow do not match. What I mean is the following: NFA reports 1Gb/1000000 packets out sent on a T3 interface, but reports only 700M/700000 packets in on the incoming interface on the other end of the T3. It cannot be a 30% loss over T3, as my app reports receiving 1Gb of data as it supposed to. It is a TCP app, so I know it got 1Gb worth of data. Any suggestions? Could it be

Matching traffic flows on two between two routers
Folks, I have two routers connected via T3. I've set up monitoring of the T3 interfaces on both routers. Since I am using some custom applications, I've created some custom labels for these apps. In theory, the application lists on both routers/interfaces should match. But the don't in my case. When I look at the downstream router, I see all the apps I am using, but when I look at the upstream router (other end of the T3) I see only some of the flows listed on the downstream router. Below is a list
Another Reports Problem.
HI, I have had no issues with reports as such, email works, attachments work, I am just not able to schedule the reports I need. There is the option to "PDF" some reports but not for the comparison reports. and what I really need is the ability to schedule the comparison reports for the last 4 weeks or so.. is it possible? I cant find anywhere to set it... any ideas would be greatly appreciated... Drew

How to prevent Alert being viewed by operator level user
I want to know if there is a way to prevent Alert being viewed by other user. I created users for each site so that they can only view their own site traffic. The problem is when there is an alert on one of the site, it is reflected globally on the general alerts section. Is there a way to localized the alert so the user can only view the alert generated by his/own assigned device groups being monitored? Thanks in advance.
Can reports be emailed as HTMP or PDF and not Zip?

Listener not working?
Hi there, I have just installed Netflow analyzer, the install went ok. The web site is fine. I turned on the flow output on our cisco router, and have checked this with show ip cache flow. But I dont think that the Net Analyzer is listening on port 9996. I am getting no graph output even though I can see the port listed by running a "netstat -a" on the server. On the server I have tried "telnet localhost 9996" - should I see a response from this? Everything I have checked seems to be in order, its
Interface speed reports way off
I'm currently evaluating Netflow analyzer pro 6.. We're using sFlow to sample packet data from a Foundry Bigiron 4000 Jetcore, and it's sampling quite nicely, but reported speeds and utilization are not even close to what it's supposed to be. On one gigabit interface it's reporting 24.54 Mbps IN and 11.68 Mbps OUT, while the real usage is 316Mbit IN and 41Mbit OUT And on a 100Mbit interface it's reporting 1.16 Mbps IN and 382.39 Kbps out, while real speeds are closer to 4Mbit in and 1.5Mbit out It's
SFLOW data
Im running Netflow Analyzer 6.0 and have just started sending it sflow data from an Alcatel-Lucent 6850. I can see this data arriving at the PC with Ethereal but I am not seeing anything in the product. What should I see and where? In the License Management? In the Device list? The data is arriving on the same port as the Netflow data (which is being processed fine). Is this allowed or must they use different ports?

Cant add user accounts in NFA 6
We've just installed NFA 6 and it appears to to be working properly but I cant add any user accounts. I can pull up the User Management screen and click the add button, the user dialog box open, I enter all the information click add and it takes me back to the User Management screen but never adds the user. I've tried to add admin, operator, and guest accounts all with no luck. Thanks Chad Westog Verizon chad.westog@verizon.com
No OUT data generated
Hi, I'm having trouble getting any data in NFA. I'm using pmacct (http://www.pmacct.net/) with its nfprobe plugin to export data into NFA.

Application mapping not working on a port I've added
Hi, I've just added UDP 4500 port in the Application Mapping to be shown as "Cisco VPN Client" but my Netflow still shows "UDP_App" and [show ports] when I go into show ports it shows the UDP port 4500 in either the source or destination. Why does it not say "Cisco VPn Client"? Thanks
In + Out = Total?
This may be a dumb question, but its early here. I have a 3Mb link between two sites. If the In is showing 1.5 and the Out is showing 1.2, should i be looking at a total usage of 2.7 (or nearly all) of my bandwidth? The chart makes it look like only half is in use - does this make sense? TIA

HP 5308xl - Enable sFlow for single port
We have an HP 5308xl switch that we would like to sFlow data from. I only want to receive sFlow data from a single port, which is port F14 on the switch.

Internet router only shows firewalls publc IP not private IP
Hi, our ISP added the Netflow settings our Cisco 2600 which is our Internet router, it's a 10mb lease line. The Cisco 2600 connects to a VLAN on our Cisco 2950 catalyst where our Cisco Pix's "outside" interface also connects. When I run Netflow and see traffic outbound it shows our Cisco Pix's public outside IP always and not say an internal private IP of a server or a users PC's private IP. I know the firewall PAT's all internet traffic and it's internal IP is Natted to a public IP, but is there
What 2 interfaces to monitor

At first I monitored VLAN 1 and dialer 1 and I copied a 500mb from the HQ to the remote site, it finished after 10 mins, so I looked at Netflow over that period on both interfaces and it only said that PC 1 at the HQ copied 10mb to PC 2 at the
