No OUT traffic on Netflow
Hello, I am facing this problem regulary that when i configure netflow, NFA does not show OUT traffic stats at all and sometimes it works perfectly fine i.e. I see ingoing and out going traffic without changing any configuration. now NFA is again showing no OUT traffic, can you please provide a permanent work around to this problem? I have restated the server few times, and re-initialise the database too, but still same problem persist. Please help me out on this issue. I have attached netflow screenshot
Netflow not exporting flows
Hi, After installing the netflow analyzer 4.0.2 and configuring the the router to enable the netflow exports but i was still unable to see anything in the dashboard view! I have followed the steps to configure the router. I'm using a loopback ip address as the source instead of configuring an interface_number. I can see the router is exporting the flows but nothing is seen in the dashboard view. At the Interface view, it states no router is currently exporting Netflow packets to Netflow Analyzer.
Report on individual router
Hello, I'm now a proud owner of NFA with 30 interfaces license and planning to buy another 60 if everything goes well. Currently busy trying to squeeze as much info from NFA. One area that I think I need is the consolidated report on individual routers. Any idea how is this done unlike the report on individual interfaces which is just point and click? Many thanks. Regards, Msaufi
Multiple logins required
I'm running v4 and v5 right now and both have had this problem on different occassions. Whenever I login, it will give me an error (HTTP status 400 - Invalid direct reference to form login page). When I backspace, it logs me into the app. HOwever, whenever I click on anything, it prompts me to login every time. I've rebooted in the past and it clears up but this isn't always an option. Any idea what is happening?

Does work netflow analyzer with Cisco 2924 xlv
Other appear on day and week scales
Dear authors! I installed NetflowAnalyzer version 5 beta recently, with fprobe-ulog version 1.1 as the emitter NetFlow packets. Hourly reports were fine, but on daily reports I had HUGE Others entry. Analysis of raw data did show differences in network traffic for some entires compared to daily report (like this: 30MB in daily report - 49MB in troubleshoot report for the same period of time). RecordCount is set to 100. What is wrong? Waiting for your reply, Eugene Fisher OILspace, Inc.
Report Viewing Errors
We are evaluating NA (downloaded yesterday) and am interested in purchasing but have a problem when trying to narrow down the time window. We have a spike everyday @ 0945 so I ran a report from 0930-0950 (see attachment). However, when I click on one of the protocols, it shows no data available. I tried 0930-0945 and the same result but 0930-1000 gives me details but no data in the volume view up top.
NFA- Drive space
I am burning 10gigs a day with NFA. Have you come up with a solution to offset this burn rate or be able to offload the data to another server and still be quickly available for reporting?
IP Groups practical Limit
This is a great Product! I've been testing it for about 20 days and will be getting it for our ISP. I was wondering what the implications of adding IP groups are? For example if we created a group for every IP address (about 4000 ip's) would it make the reporting much slower? I've been testing it on 3 ghz 2gb ram 100gb drive Windows 2003 server. Would it run faster with mulitple processors or if I ran it on a Linux system similiarlu equipped? Thanks, Obetwo
Couple of questions
1) What is the recomended hardware to monitor 2 routers, 3 interfaces in total transporting about 200 mbit/s We are currently using the free version of netflow analyser on a pentium IV 2.0 GHz but generating reports is extremely slow (2 hours to generate 1 report), seems to be coused by loads of write operations by the Mysql daemon. 2) Is it possible to get information about the followed AS Paths, we are currently monitoring an internetexchange port and 2 transit ports, however it would be helpfull
Configuring netflow on cisco dial-up interface (BRI/PRI)
All, does anyone know how to configure netflow on BRI interfaces? Does this need to be configure on the BRI x/y or on the dialer interface. Are there any specific commands required? We are looking to start using this application, but monitoring on dial-up links must be working before implementing. Thanks for your feedback. Ronnie

Softflowd with Netflow Analyzer
Has anyone had experience using the Netflow sensor 'softflowd' on a Linux system http://www.mindrot.org/softflowd.html with Netflow Analyzer. I've got my Cisco routers sending Netflow v5 flows to the Netflow Analyzer and they show up fine. When sending the flows from softflowd to 'flow-tools' http://www.splintered.net/sw/flow-tools/ ; the collector picks up the data fine. However when using softflowd -v 5 -n x.x.x.x:9996 where x.x.x.x is the Netflow Analyzer, nothing shows up although a packet sniffer

Eval - high cpu, server shuts down
Hello, I am evaluating the software on a fairly small network with an admittedly old server, but capable nonetheless - W2K Advanced Server, P4 with 1GB ram, and all it's doing otherwise is mail (MDaemon). I have a Cisco 1760v router, monitoring 2 interfaces - one is 256k (TX only), and the other is 384k (RX only). Now, I've installed the NetFlow software, and I get to the webpage, see the graphs, etc - all seems to be working as expected. But then, the webpage becomes unavailable. So I check the
no OUT traffic in IP GROUPS
Hi All, I hope someone can help me. I am new to Network Analyzer 4...and like what i see so far. Im having a small issue. I am not seeing OUT traffic for any of my IP groups. I can see IN/OUT traffic for an entire "iFindex",but, when i select an IP group it only shows me IN traffic. This was working fine yesterday. Not sure what's going on. If someone has any insight that would be helpful...i'd appreciate it. I am mangaging a cisco 2811 router. thanks.
NFA seems not to listen on port 9996

Question about licensing and interface monitoring
NFA licensing is based on the number of managed interfaces, and the free product allows me to monitor two interfaces. However, there's something I'm not sure about. Let's say I have a router with two interfaces and I just want to manage one of them. If I only turn on NetFlow on that interface, I'll only see ingress traffic. In order to see egress traffic, I'd have to turn on NetFlow on the other interface, but that would use up the two-interface license if I manage both interfaces. If I turn on NetFlow
Monitor VOIP Traffics
Can anyone point me in the right direction on how to monitor the amount of VOIP traffics in a router? I have IP GRoup defined to capture the following ports but I think I'm still missing something; Port: 5060 Protocol: UDP Port: 1719-1721 Protocol: UDP / TCP Please help. Zinko
Feature request for syslog alerting
Since email alert is added in NetFlow Analyzer v5, could you also add syslog alert with capability for customizing, such as add text prefix/suffix to the body, and include/refer the managed object variable, such as device name/ip? so that the existing alarm automation can cut ticket on the threshold event. thanks. -Peng
Email Settings
I'm running the evaluation version of the v5 beta and I'm playing around with the email alerts. Is there a way to configure the "From:" address? By default, the sender is netflowreport@localdomain.com, but I'd like it to be something else. Is that possible? If not, consider it a feature request. :-) Thanks, John
Feature Request
Would consider the following two changes for future release. 1.) The ability to lock the dashboard view, so that new interfaces are not displayed. The reason for this is that we regularly have new interfaces displayed, these are always erroneous interfaces, caused by router modifications, and we have to go in and manually unmanage these new interfaces. 2.) On the dashboard view, this shows an instanteous view of all interfaces, could there be an option to view all interface traffic volume over one
Strange values in "IP group" reports
IP group reports has very strange values for traffic and speed counters. You can see all reports in attachments. IM�� the main reason for such values - is sum data from all interfaces/routers for selected subnet. So, if we have netflow data from two interfaces/routers, values in "IP Group" will have double/triple/etc sum value instead real value. In this case (without group by interface/router) this feature (IP group) is completely inefficient. Any ideas?

International charset support
There are some problems with international charset support. For example, traffic report (/jspui/traffic.jsp) look like this: Traffic IN Details Time Traffic ???-18-05 09:50 6.59 KB ???-18-05 10:30 41.91 MB ???-18-05 10:40 41.93 MB where instead '???' must be short month name '���' (cyrrilic/windows-1251 charset). Also there are problem with international chars in some titles like: '???? - Dashboard View', where '????' is international chars. For PDF exported reports also there are problem with international

Feature Proposal: Average Trending
Hi, A good tool to approach a long-term trending would be to graph the average per day of a line, application or IP on a one month, one quarter basis. So everyday, we take the average, store it on a table and graph it when requested. This would give the trends for the last month, quarter, year and take action on a possible line upgrade. regards Ced
Data Billing
We are looking at using Netflow analyzer to bill our clients for data usage at an IP level. Is anyone using the software for data billing purposes? If so what have been the results? thanks in advance regards, Steve
Separate the bundled mysql server into a different server
This is probably already discussed and maybe answered. In this case please consider my question as an opportunity to update/verify either the product features or the development roadmap. So, is it possible to separate the bundled mysql server into a different server? I saw the mysql-ds.xml file but i believe that just by changing the "localhost" many other things might break, like the "LOAD DATA INFILE" operation which should rather change to "LOAD DATA LOCAL INFILE". Is that right or the application

Scalability issues
Hi all, I am evaluating Netflow Analyzer and was wondering if you could help me with questions concerning an Analyzer setup for NFE devices of a larger company network. In particular, what do you recommend as maximum number of Netflow sources for one box (where the analyzer runs) and what specs should this machine have? From what I saw so far, it is not possible to analyze data on one machine provided from several data bases on different machines, is this right? Thanks and greetings, Melitta PS:
