New Routers not showing
I have had NetFlow Analyzer running for quite some time with 8 routers showing in the listing. I recently have tried to add three new routers by configuring them to send NetFlow packets to my Analyzer server. I can see the packets getting to the server with a Sniffer, but the routers are not showing up in the device listing. Is there something else I need to do to discover the new deviecs? Thanks.

Do you have an estimated time frame of when your software might be able to use a MSSQL DB. Thanks

NFA Report Discrepancy
When compiling a custom report, NFA isn't reporting the highest bandwidth percentage utilization for the time period specified. Instead, it is reporting the highest bandwidth utilization ever reported to the server. For instance, the graph shows a utilization of ~10% which is correct for the time period, but the data directly below shows ~42%. This conflicts with the visual representation of the data. Has anyone seen this before? I am performing throughput testing and this discrepancy is corrupting
why report chart delay 10 minutes
hi, I think NetFlow Analyzer is cool, but the report chart flow curve is delay about 10 minutes. Why? Is NetFlow configuration not correct in Catalyst Switch 6500 ?

install and conf of netflow analyzer for best performance
hi i am a university student ,working at my university's computer center (in network department) , our network admin assgn me to manage our neflow analyzer, about 1 week before. our netflow analyzer 5.0 is working very slowly, report for last hour is open in 10 mins , i think it is becouse of opur hardware configuration, which is 1GB of RAM , 70 GB of Harddisk and (Pentium 3)x86 family 6 model 7 stepping 3 CPU (CPU utilization is at 90 , when we start the netflow) so we decided to get a powerful
How to tune netflow export on Multiple VRF router?
Hello support team! Customer have complex VPN topology eg DMVPN + Multiple VRF (no MPLS, just 2 different contexts to separate system and VPN traffic), Customer want to export netflow from each router to a two different analyzers (best scenario), First collector is a in the regional center (can be reached through VPN VRF context only) second collector is in the central site (can be reached through System or VPN VRF), I failed to find any recommendations and explanations about VRF aware NetFlow on
Inconsistent output?
Hello, I have been trying this NetFlow Analyzer & I found it a pretty cool tool , really helpful in analyzing traffic. However, I would like to know why the displayed historical info is not consistent. I have saved the page for conversation within a time stamp. but then when I run the analyzer again (say the next day) for the same time stamp (and same date or course), it gave different value (traffic) and different users (as top talkers). May I know why is that so? Please kindly share. TQ.
Question on Traffic vs. Application tab totals
Greetings, I have been using your Netflow product for a while to demo it and like it very much. So much in fact that I'm also investigating into your other products that I recently posted about (OpManager and AppManager.) I have a question on the totals when looking at a device or group. Attached are two screen shots. The first is a screenshot that shows the Traffic Out total of 194.92 MB. If I immediately click on the Applications tab (selecting the Out radio button of course) I see a total of 179.58

How to view TOS reports?
Hello. How to view TOS reports in NFA 5.5 (003)?
Receiving Non V5 / Non V7 packets
We have NetFlow Analyzer v5.5 installed. As I see on your web pages it supports NetFlow V9 packets, too. Since, some Cisco equipment send v9 packets by default, I am interested to know why do I receive "Receiving Non V5 / Non V7 packets" messages in Analyzer, if it supports v9. Is it a configuration issue in software? But, I can find where is it supposed to be configured. Looking forward to advice from you. Regards! Vladimir
Feature requests:
Any pages that contain a print buttion should also have an export to pdf option. The print feature clips much of what is on the page, i typically have to open the report in another new window to get a print preview and set the page to landscape prior to printing. NBAR reports should drill down into the application, just as they do under the application tab perhaps. Graphs should be available in the troubleshooting reports and also in scheduled reports.
Old data in database
hi, I am continuing with the Evaluation .... !! I found that the old data of routers / interfaces in the database cannot be removed even they are "Deleted" from the Lincese Management. This lead to a problem that we are facing. After we change the source IP of one router, we try to delete the old records (the old data is not needed anymore) and rename the new IP with the same as the old one. (Same name). However, the system does not allow me to do so, probably because the same name has been used
Frame Relay Utilization over the Max Capacity

netflow analyzer 5 working very slowly
hi to everybody im a student, and i am working in the university's computer center, our network administrator assgn me to manage our netflow, and this is my first date 3rd day at work. i realized that netflow is working very slowly and sometimes the netflow server locked becouse of high cpu usage, our hardware conf is: 1 GB of RAM x86 model 6 family 7 stepping 3 CPU (PENTIUM 3) and around 67 GB of HardDisk software conf is: Windows Advanced Server 2000 SP4 if anybody tell me the reason, is the hardware/software
Database: 11G -> 85GB with no change :(
Hi all, My database appears to have gone from being around 11GB on Tuesday to 85GB today; worringly, we didn't make any changes to the raw data store as we know we can't store more than a day because we would run out of disk space. I know this is finger in the air stuff, but anyone know why this could happen? I can see JVM hung and tried to reload, claimed it was registered to null and failed. Thanks,

Custom reports
Hi, i have some difficulties to comprehend the data gathered from a custom report. For example: i create a custom report from a source network to a destination network that lies 7 days back. I get something like this: Source-IP----Destination IP---Application---Port(src/dest)---Protocol---Traffic 10.10.10.1 20.20.20.1 http 80 TCP 100MB Is this the summary of traffic from 10.10.10.1 to 20.20.20.1 including the client traffic? Because i cannot see the TCP-Highports from the client communication. Thank
Destination AS
Hi, Is their a way to identify the destination AS which you are sending traffic too with NFA? I'm not on about the traffic that you see going to your AS neighborships from the dashboard, but the overall traffic travelling to the final AS. This would enable you to decide which AS's to peer with better, and also help with the process of deciding which IX's to be present at. Thanks, S

Application and Conversation Data not matching
Hi, WHen i generate IP accounting for an interface in the application Tab it gives 27GB data mapped to HTTP , where as once i click HTTP to get the Top talkers using HTTP applicaiton it gave data for 400MB only.

Running Netflow and Firewall Analyzer on the same server
Hi Guys We currently run Netflow Analyzer, and are also interested in Firewall Analyzer. My question is this, can both these applications run on the sames server and if so can they share the same instance of MYSQL or do they have to run seperate instances? Are they OK running on the same server or would you recommend running them on different servers? Thanks Lee
Netflow and per-packet load balancing
I just started using the demo version of NFA 5.5 and I'm running into a problem. I'm monitoring two serial interfaces on a router and I'm getting anomalous results that I think are being caused by per-packet load sharing. The problem is that the output utilization charts and tables are often going well over 100% of the link speed. The link speed is configured correctly and the active timeout is one minute. With per-packet load sharing, traffic for a given destination will be even split between the

Feature Request Flow Map
Hi, Great product, trialing it at the momment, one feature we would love to see in it is a Flow Map. Bascially this would be a MAP or View of our routers connected together and the links between these would corrispond to the flows runnig between them. The links themselves would change color as the traffic increases and decreases, this would provide an easy way to view the preformance of our network. This would give a more dynamic feel to our monitoring of our routers. We are trialing another product
