In OUT Traffic issue
Hello, I am having a problem, i am using netflow analyzer v 4.0.2 and its been working smoothly for last couple of weeks, now the problem is that after restarting the server it is NOT showing any OUT traffic on my interfaces and currently its showing wrong incorrect traffic stats on my link, mean to say my internet link is utilizing 1.9 MB traffic while netflow IN Traffic is stuck to 500-600 kb and OUT traffic is 0 bps. PLease tell me what has happened? before it was showing proper stats and was

How can I add the Port Information after the 2 hours have p.
Hi, We have the Netflow Analyzer running for a few days and are going to buy it if we can sort out the last problems that we get. For now it is the Problem with lost TCP and UDP Ports. As I could see from the documentation and other posts, the Button to see/change the Port Description ( if unknown ) disappears after 2 hours. But how can I change it after these hours? Thanks Chris

I have installed SNMP on the server , but this server is not reflected on the SNMP report , why?
Serial link utilization
Hi guys This is a question for the NFA guys and everyone else here please. I'm running NFA monitoring serial interfaces on my core routers, each hooked up to a 2Mbit pipe to an MPLS cloud. I'm intrigued by the concept of utilization here, as my links rarely get above 25% utilization. What confuses me is why, when I can send data to the router on the LAN at 100Mbit (or even any speed above 2Mbit/s), it doesn't hike up the throughput to 100% until my data has cleared the link before dropping back down
HSRP Cisco
Just configured my 2 Ciscos for HSRP and Netflow Analyzer has thrown a wobbly. It sees the 2 "real" Ciscos and the "virtual" one, but reports no stats on the "virtual" one - which is the one I am interested in. Any ideas? Thanks - Adrian.
There may be a configuration problem: please check the log
I had one of my techs install the netflow software to a new box recently. It seems to be working fine except we have to reboot the box every 24 hours because the service keeps shutting down. The event log shows the following message... "There may be a configuration problem: please check the logs.". I also get a message that the service tried to restart 5 times unsuccessfully. Which log should I be looking at and should I sent a copy your way? Thank You, Joe
Traffic not counted?
Hello, I'm evaluating the Linux version of Netflow Analyzer. I noticed that on every SOURCE OUT report i do, it appears to be some traffic not assigned to an ip. I'll explain: we have +/- 80 ips, belonging to servers. All of them pass by a Cisco 7204 router, the one which exports netflow data. As you can see in the attached image (it's a 30 minute period report), there is a list of ips and its out traffic. The first one 278.2MB which represents 12% of all out traffic, etc... All OK, but in the end
No stats after a few hours
We are currently evaluating Netflow Analyzer 4 to make sure it will properly work in our environment. Although the problem we are seeing is that after about 2 hours there is no new netflow data being processed. It is still running and we are able to access the webpage but all the latest stats are at zero. I'm thinking now that it simply can't handle the load. We are exporting netflow data from 4 Cisco GSR's totaling about 450Mb traffic combined. The spec's for the hardware are below. I would assume
Bug with new user account?
Hi, When I try to create a new user account with a password length > 10 characters, the user is not added to the system and there is no error message. When I create a new user account with a password length <= 10 characters, the user is added to the system. When I change the password of this user with a password > 10 characters, it works without any problem and I'm able to log to the system using this new password. I'm using build 4020. Regards,

change ip address of NetFlow server
All, we have a need to change the IP address of the backend NetFlow server itself. Aside from having to change the export IP address on the respective routers we manage, and changing the IP address of the server, what do I need to do for the NetFlow application on the server itself so it continues to operate for us? Thanks, Dan

TCP APP List: Maximum Items
Hi, Especially just after the install, looking insed TCP_APP is quite usefull to fine tune Netflow Analyser to match with internal applications. However, Having informations inside TCP_APP takes a long time. Why not limiting the output to the TOP100 ? it would take less time to get the information. regards Cedric
IP Group and TCP_App and Graph's colors

Source, Destination, and Conversation Hang
I am running a P4 2.7ghz 2000 server with 1g of RAM. I have two issues at the moment. 1. When I click on the Source, Destination or the Conversation graphs they either don't come up at all, or they take about 10-15 minutes to come up. Is there something I can do to speed this up? I am on an OC-3 link, and I am monitoring only two managed Gigabit Ethernet ports. The traffic comes in to the East coast from the west coast. The average traffic flow is about 70mb. 2. I am getting three interfaces managed
Source and Destination graphs
I am exporting two gig interfaces to my analyzer, but I cannot get the Source or Destination tabs to work, nor can I get the Coversation tab to come up either. It seems that they hang up or just sit there for ever. Could it be that there is too much traffic coming in for the system to handle it? It is a P4 2.7ghz with 1g ramm. Seems like it would be powerfull enough to handle it. I also notice that I have three interfaces reporting to the box from one router, even though only one router interface
Netflow across WAN
We installed and tested Netflow with a Cisco 2600 router successfully on it's on test network. We wanted to monitor traffic on a remote site (connected through T1) from our home office. The router we are trying to monitor is also a Cisco 2600 but we do not see the router in our monitoring interface. We can ping the router from our home office. What are we missing? Thanks.

Autonomous System View
Greetings, I am currently evaluating the NetFlow Analyzer. I think your product has a wonderful interface. We have a Packeteer that is exporting the NetFlow-5 data, rather than a Cisco router. I don't know if this is a supported configuration, but it seems to be working. I do have a few questions. 1. There are moments where there is an inexplicable spike in traffic. The spike is much greater than the allowable bandwidth on our line. Things start to appear in the "Autonomous System View," which I
NetFlow Log File
NetFlow has placed a log file called flow_log_1.txt in my /tmp directory that has completely filled up the / directory. Is there a way to tell netflow to place this file somewhere else that has more available disk space? Also, how big does this file get?

Cisco 3550 doesn't report much traffic
I have a small test network at home, I just started evaluating NFA 4.0 this evening, and I think I'm in love ... however my ws-c3550 doesn't have much to say for itself. I fired it up, got it exporting flows, and hooked a laptop to it to generate some traffic. I've pushed maybe a gigabyte through it and the reports just a few KB. I recall from years ago on the cflowd mailing list that the routing engine makes initial decisions which result in flows, then the work is pushed to the ASIC level in the
Updating to 4.0.2
Is there a problem with updating Netflow Analyzer through RDP (Admin Mode) on Win2k3?? I was able to backup the DB, but then... I can't get the updatemanager utility to pop up after running it on updatemanager.bat/.sh It just runs and then shows the next line waiting for more input.

non-live netflow data?
I'm working for an ISP, and we got billing system that imports netflow data, captured as files via flow-capture (from flow-tools, common unix package for netflow). Billing system have very limited capabilities for traffic analysis, so we need an instrument, well, like NetFlow Analyzer ;). So, i've got a question - can NetFlow Analyzer work with data from files, not directly came as netflow udp packets? Actually, it's possible to "retransmit" captured data as netflow packets via flow-tools, but that's
IfName & Catalyst 6500 CatOs
Hi, I've enabled netflow on a Cat6500 in CatOS Mode. Netflow exports informations in version 7. Instead of having port number, i've got the the connection type like 'short wave gigabit ethernet' which is useless. In terms of snmp queries, instead of having IfDescr, i need ".iso.org.dod.internet.mgmt.mib-2.ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName" Is there a way to change this ?
