Top Talkers
What is the quickest way to see "top-talkers" from a site ? or to a site? I have netflow activated, with the "top talkers" option turned on. Most of my clients want to see who is using bandwidth quickly and easily. Thanks
Imagestream router and NetFlow Analyzer not working as expected
I am testing this product with a single ImageStream router. I have two interfaces on the router, eth1 and eth0. Both interfaces are configured to dump flows to the NetFlow Analyzer box. The router has multiple network on eth1, with a class c sub-netted. The router shows up ok, I see Interface ID: IfIndex255 I have set some group ips. by network and ip. On the interface speed for the router, there is no IN only OUT. Why? On the Dashboards tab, Top devices by speed Pie graph, says No Data to Display.

Troubleshooting Time on Graph Data
Hello, My apologies if this has been addressed previously, but I could not locate an answer for my situation in the forum search. This morning I had a situation where I needed to view the NetFlow data for a router interface which is located in the CET timezone (GMT +1). The router reports to a collector located in GMT. That collector reports to our central server located in the PST timezone (GMT -8). There was a usage spike around 7:20 AM GMT that I wanted to investigate. I would expect this
Nortel ERS 5500 Switches and IPFIX On NFA
Hi All, I have a call open with support regarding an issue i have with gathering flows from Nortel ERS 5500 Switches. I want to check with other users and see if anyone has been able to collect correct flows from these devices. My problem is related to Egress flows, it seems that the switches (using preipfixv9) do not mark their flows with the out port identifier. thus NFA cannot calculate the egreess onthe port. I have a case open with Nortel, so i expect a responce from them early next year !!

Cisco pix 506e Problems
Hello To Whom it may concern I have a Cisco pix 506e which is refusing to establish any connection with Netflow.

Bi-weekly report from the monthly data
Using the custom reports is there a way to automatically run a report for the previous two weeks using the scheduler? I don't mind that it is using the data smoothed out for the month but I want to avoid having to go in every two weeks to manually generate the report. I guess what this would look like is a "custom" report that is automated to just run every 14 days on the previous 14 days data.
Catci SMNP vs Manage Engine Netflow – Approx 8 to 10% difference data readings.
Hi guys is there any way to tweak the total amount of inbound + out bound data Manage Engine Netflow displays for a IP group over "x" amount of time. When I compare netflow results with catci, netflow is under reading slightly. Whilst I believe the netflow figure might be actually correct, is there to manually adjust up (or down) the value displayed within manage engine netflow. Ie add 10% to all the values show / stored within manage engine netflow so I can have both our netflow system and catci
Graph problem
Hi, I have a 12M microwave link connected to cisco 2811 Fastethernet 0/1. The netflow graph sometimes shows peeks up to 75 to 100M which is a bit odd. The MRTG graph at the ISP side is showing the correct graph which is 12M maximum. I checked the 5 minute input rate and 5 minute output rate on the router interface and they never exceeded 12M. other routers are displaying the bandwidth usage correctly. netflow version I am using is 7.5 build 7500 any idea what could be wrong Regards, Ramzi
IP adresses and device names
Hi! I've just started using NFA and there's an issue that I can't figure out... Our network is quite big, about 2 dozen of routers... I configured the devices and they send netflow data to the server correctly, but when i see the devise list in the Dashboard some of them are represented by IP addresses and some - by domain names like <hostname>.qqq.xxx On every router there're command ip domain-name qqq.xx, ip name-server <address> and hostname blabla, and none of the devices are resolved through
Disable netflow statistics on single interface
Hi All, For example I have configured like below in one router and getting statistics from all interfaces. ip flow-export source FastEthernet4 ip flow-export version 5 ip flow-export destination address 9996 I found in the below link to disable netflow on single interface use "no ip flow-export destination address 9996" but when I entered this command under any interface then the primary command (ip flow-export destination address 9996) on the router is gone. Can anyone telll me how we can
Is it possible to produce a weekly report, showing daily usage??
I receive a report each day that shows daily usage. I also receive a weekly report that shows weekly usage. I would like to get the report once a week, but be able to see a breakdown of daily usage. I only need the total in and out amount, since I am using this to track a 3G connected network's approach towards its monthly limit. I would be happy to just see a text log of daily data, where each day's data is appended to the log. Alternatively, I would be able to achieve a similar outcome if I could
NetFlow statistics not coming completely
Hi All, I have 8 MB MPLS link connected to Coreswitch (4507) at my DC, hope we all know that 4507 will not support to configure netflow unless add some external card. The MPLS is managed by provider, they have edge 2811 router at my DC, so I asked them to configure netflow on our interface in their router (2811). They have configured as like below. (config)#ip flow-export source Fa0/0 (config)#ip flow-export version 5 (config)#ip flow-export destination 10.246.6.50 9996 (config)#int Fa0/1 (config-if)#ip
How to import netflow data

Mac Address
Hello, I am trying Netflow analyzer at my office. I use microsoft DHCP to serve client IP address. I need to create report every each host, the problem is this analyzer show report in IP address and when I try to resolve DNS and the hostname result is not valid (means it is not correct host). is there any way to create report base on Mac Address ? or may be there is a way to resolve the IP with the correct hostname ? Thanks, Yoso

tunnel IPSec-Gre in and out traffic
Hi, I have the folowing scenario one HQ VPN router and one Branch router connecte with an IPSec-GRE tunnel. All interface for each router (HQ and Branch router) are configure to export netflow to NetFlow Manage engine server. I compare traffic from OUT tunnel traffic from Branch router -> IN tunnel traffic from HQ router and IN tunnel traffic from Branch router -> OUT tunnel traffic from HQ router. The traffic should be almost the same out->in and in->out from Branch->HQ but: 1. I saw that ntp,

Microsoft SQL
We are testing netflow with Microsoft SQL 2000 and have found a few major issues: 1. We are unable to port our configuration per the procedures outline by manage engine. Has anyone had any luck doing this? 2. We also have observed that in build 7600 when you configure it for MSSQL, the netflow service will not start unless you allow the application to create the database. This makes using a restored database impossible! Has anyone had any luck restoring MSSQL database from a .bak file and using it
MSSQL
We have been testing Netflow install with MSSQL and have found some configuration issues: 1. We have been unable to migrate our configuration to MSSQL. We have referred this to support, but I have been unable to ID this issue anywhere on the forums. -Has anyone had success with migration configuration from MySQL to MSSQL? 2. During testing and install of build 7600, I have found that netflow service will not start if you do not allow the ChangeDBserver script to create the MSSQL database. This inherently
Netflow 7 collector up/down notification
Hello, my question is: whenever there is a problem with a collector, I receive an e-mail alert "collector down" - which is very nice, but no alert when it goes up. Obviously I will know, once the issue is fixed - power down, connectivity etc, but in the long run, it will be easier to log events if I could turn on notification for "collector up" for instance. I found no settings related to collector state alerts, is this possible? Thank you

Experience with Netlfow probes
I was wondering if your product works with netflow probes (nprobe by ntop.org, Cyclades Nquirer) Since Netflow Analyzer won't be able do an SNMP poll on the device, how does it figure out the interfaces? Here is what i am thinking. I would be mirroring a port through which the traffic flows and the probe would "sniff" all the packets. The application will convert that into netflow v5 flows and send them to the netflow analyzer. The reason i need to pursue this is because there are no cisco router
Imagestream Router Only 1 Interface
I'm using several Imagestream Routers, which use nprobe I believe. I set up just one interface to send data, and it sends all in and out data. It does show who is doing what and where etc. However it does not separate the IN from the OUT. I've set up the correct SNMP parameters. Is there anything I should be doing to get an accurate reading from these routers?
NetFlow Analyzer build 7002
I just upgraded my install and now, none of my IP groups show any data. All of them are showing data leading up the upgrade but a blank after that. Also, probably related, I cannot add new IP groups or modify existing ones (with the exception of deleting). If I attempt to add new or modify old, when I hit 'save' it takes me to a blank screen.
Traffic IN is not the same as traffic OUT on Foundry devices with sflow
Hi, we are using Netflow Analyzer 7.5 (7600) on a Linux Machine. The Software collects Data from Cisco Routers with Netflow and from Foundry/Brocade Switches with sflow. Netflow in combination with the Cisco devices works fine. The data from the Foundry/Brocade Switches doesn't fit together. Two Foundry SuperX with latest firmware are exporting sflow data for one 10Gbit/s Interface (this is the link beetween the two devices). If we compare the interfaces in Netflow Analyzer we will see 5,39GB Incoming

Hello there, So we installed netflow analyzer to test it out and had some problems with languages. Was thinking it was our server but seems there is the same problem on your Live demo, i attached a screenshot of one of the problem.

Alerts based on 95percentile thresholds on interface utilization
I see that NFA already doesn't 95% thresholding, i was wondering we can generate alert based on auto threshold of 95%=, some thing similar to what we have under alerts and we can specify the % of bandwidth. Which is ok on low bandwidth circuits but for gig circuits and FE circuits they are never close to say 80% and it would make lot of sense i can generate alert saying that generate a major alert if bandwidth is >95% threshold for more than 10 minutes.
