Upgrade to Netflow 5.0. No X11 installed
Hi, I've installed NetflowAnalyser on a linux server whitout X11 libraries. The Updatemanager.sh requires them. Is there a way to avoid installing X11 libraries ? (like a manual install of the package ? ) regards Cedric

Netflow OpManager integration
Hi, I have downloaded an evaluation copy of Netflow 4 and installed on the same server running Opmanager 6 SP2. OpManager uses port 8080 while Netflow is configured to use port 8081. Netflow by it self is working fine that is if I connect to http://servername:8081 I have no problem however if I go into OpManager Interface Details and select Top Applications or any other option from the Netflow Menu I get and internal server error message. Attached is a screen capture of the error message. Thank you,
Possible to use multiple IP addresses?
Hi, We're currently running NFA 4.0.2 on a machine that has multiple network interfaces, but only one interface is configured. Is it possible to configure NFA to listen for flows on one interface/IP address and have it serve the web front end on another interface/IP address?

MySQL Memory Szie
Hi, Could you give me some idea of memory requirements for the bundled MySQL process. Monitoring 1 interface for 1 day sees the 'mysqld-nt.exe' grow to about 165MB. Is there a limit to how much memory this will use? I just want to make sure that this process wont affect anything else that might be running on the same server. Thanks.

No router assigned - linux fprobe
Hi, I have read the post before. I am using a linux router that has fprobe as a netflow probe. When configuring the netflow analyzer I get the same in the router section. I however configured the ip segments under "IP groups" and see traffic etc. Is this normal or am I doing something wrong. Thanks Wynand

TCP App: setting some limits
Hi, When you select a last hour graph under the application tab, the TCP_APP and a clickable icon. When you click on this icon, it gives you all traffic seen that Netflow cannot categorize. This is a huge list in a heavy loaded network. Is there a way to limit this to the top 100 instead of having all of them. regards Cedric
Ip Group Management
Hi, First off, I'd like to say, I'm impressed with this NetFlow Analyzer! Its very nice! Easy to install and to get working right from the download. I'm looking at your Beta Version 5 NetFlow Analyzer and I have a question about adding IP groups. Is their a easier way to create groups of IP networks under the IP Group Management GUI other than through this GUI? i.e can I create IP groups by importing from a csv file? I found that I can only add 15 subnets to a group. If I add a 16th network to a
HELP..... Is my traffic correct ?????
Hi all, I have tried to read previous threads to solve my questions but i have not found a solution yet. I have inherited some routers and their configuration. I receive internet and mail traffic from an ATM PVC Link. It receives traffic ok, but i used to see both ESP traffic and http and pop3. I have found that the main router that i am running netflow on was only enrypting part of my Subnets range and not all of them. I have talked to my 'PROVIDER' and they did the changes on their router and so
Traffic spikes and router active time out
Starting from build number 4010, NetFlow Analyzer shows traffic details with 1 minute granularity. In order to see accurate reports, please set the active timeout setting on the router as 1 minute You can do this by configuring the router as: router-2621(config)#ip flow-cache timeout active 1 In the absence of this setting, you may see spikes in the traffic graph. Please get back to us in case you have any further questions Thanks The NetFlow Analyzer Team

Beta 5 problem and question
Using Beta 5 as an evaluation, so far I really like it! One small glitch I noticed, I changed the listening port to 9190, then to 9199. The main page still says that I am listening on 9190 when the configuration screen says 9199. Also, I am trying to collect flows on 2 interfaces, but I am only seeing flows connected on the first interface. This is a Linux box, I'm using eth0 and eth1, no flows are showing up on eth1. Thanks, Dave
Netflow Main Interface View Metrics
The Interface View is metered in MBS - what about on GIG ports - there they show up as red because they show over 100% utilization. Is there a way to adjust this?

Bandwidth Mismatch
Hi, I have installed Netflow Analyser 4 on Linux. I have enabled the flow-export on my router. When I compare the bandwidth which is showing on the Analyser window and on the interface of serial, it is not matching. For ex. on the analyser on serial link it is showing 300K as traffic, but on my router it is showing 1.4Megs. Kindly someone help me in this regard why it is not matching ????? Regards, Girish.
Application Scaling and capacity
We have 2 7600 Routers with GigE connections to the internet, 1 on each router with full BGP-IBGP setup. What kind of hardware would be recommended for this setup. Would the application scale to that? It looks like it will, but that is a lot of data. thanks

No Inbound
hello, i got a point to point link, let's say in point A shows no inbound traffic and but has an outbound traffic. Why does point B only has an outbound traffic, where in fact it should get an inbound traffic from point A as well? I know if I monitor a single interface I'll get the same result since it point to point but there's no inbound traffic. thanks
Percentage more than 100%
How can this be possible ?
no outbound data
Hi, I am monitoring traffic for a cisco 837 router and on all the interfaces i have noticed that only inbound data is available. No outbound is being collected at all. I have enabled all interfaces. Regards, Florian S.
timestamping of netwlow events
First of all, thank you for a fine and powerful tool for traffic analysis. Nevertheless, I'd like to note on some inconveniences. Seems, NetFlow Analyser is using a current time (on a running server) for stamping accepted netflow datagrams, and is not using the time, that has been used by a router/device for stamping netflow PDUs. This is not quite correct for estimating real time of flow/traffic events. i.e. it is not possible to reproduce netflow by any proxy tool like flowtools and direct it to
Final Release

Multiple routers behind the same Firewall and IP address
We are trying to capture netflow from 4 different routers (with multiple interfaces) behind the same firewall. We have enabled netflow on them and some of the interfaces appear in the analyzer under the 1 public IP address of the firewall. It appears though if the ifindex number is the same or duplicated on multiple routers we only get 1 of each name into the analyzer. For example if ifindex1 is on 2 routers we only see 1 interface not both of them and its also hard to determine which of the routers
