Time Sync Override
We have a need to analyze historical netflow data that has been recorded as raw UDP packet data. When replaying the netflow udp packets into NetFlow Analyzer it appears that the data is rejected because it is not synchronized with current time. Is it possible to disable or override the router time synchronization check inside of NetFlow analyzer so that old data is processed and added to NetFlow Analyzer database?
Can't start Netflow 7
Hi. I have Netflow installed in a server with Suse 10. Today I have to restart the server. Now I can't get started the Netflow service. I go to the init.d folder, and type ./netflowanalyzer start, the program starts, but I can't access to the web interface. It says that the connection fails or the connection was reset when it was negotiating. And after a few minutes the service stops. I try also with service netflowanalyzer start, and the same thing happens. I really don't know what to do, and I'm
NFA failing to show Application and Conversation tabs
Hi, we are currently testing NFA as a solution to monitoring our routers, in this initial test we have used a HP Proliant DL380G4 with 3GB Ram, 306 GB disk space for NFA hardware Raid 5, on a RedHat Enterprise Linux 5.2 i386. The system has been tuned using values from guide, mysql has been tuned to 2GB Ram, and java parameter has been set to 1024 as explained in tunning guide. Record count has been set to 10, trying to get things faster. NFA running as a non privileged user. Currently 2 Routers
Netflow Analyzer 7, Radius and dynamic IP tracking
Have question about tracking dynamic ip traffic. Here is currently how we are setup. We have two static pool subnets, 2 dynamic pool subnets, Netflow enable and tracking, netflow analyzer up and running. Customers radios use a radius server to authenticate through. The problem I forsee us having as far as tracking bandwidth and such is that the dynamic ip's will change and will be assigned to someone else and thus tracking will be useless for that person as the ip will belong to someone else. I know

Virtualise Netflow on VMWare
Hi, There are a couple of postings already for running NFA on VMWare. Is there anyone out there that is using it this way successfully? We're currently running around 120 interfaces, with a flow rate near 1500 per second. Our current hardware is not up to the job now (HP G2), and we're upgrading the network at the moment and will require additional interfaces, and more disk space (currently at 240Gb, for only 3 days RAW data). We're trying to consolidate these backoffice apps onto VMWare to avoid

cbqos graphs stop after changing cbqos on router.
I've changed the policy-map on the router and now I can't get any graphs for the cbqos on it. I've tried to disable and re enable cbqos graphing within Netflow analyzer, but still not working, Cacti is still getting good info after changing back to original setting on router. Do I need to clear any settings on the server before the cbqos is graphed again. This is inbound on an interface cisco7301. Regards Mark
HP ProCurve 5412 sflow to Analyzer
I have 4 hp procurve 5412zl with fiber uplinks and 24 10/100/1000 ports in each module A through J. I want to monitor the total traffic on each of these switches and be able to drill down to the indvidual workstation on my network. I enabled sflow on my procurve for each module but now every port is showing up as an interface. The two problems I need to work through are one how do I know which interface is the fiber link to see traffic and only monitor that. If I monitor ever port that is over 900

Interface Group Utilization reported shown incorrectly
I'm using the Enterprise Edition of NFA. On the "All Devices" page that shows all of the configured interface groups, the bandwidth graphs are showing incorrect percentages. On the "all devices" page, it'll show a group of serial interfaces using >100% of the bandwidth at 3Mbps, but the group is configured for 22Mpbs. The "description" of the interface group shows the correctly configured bandwidth. If I drill down into the group and show the Utilization graph, it shows correctly, also. Only the
NFA 7 reported link speed incorrect
I am new to NFA and have just installed v7. During the trial period, I didn't see any problems with the bandwidth usage being reported, but after making traffic changes on one of my main links, NFA is reporting impossible numbers. Example: Yesterday, I moved a lot of additional traffic onto a core T1 link in preparation for some network design changes. Standard 1.54mbps pipe handled an Adtran 4305 router running AOS v17.02.03. While downloading a large update file through this T1, NFA reported a

Hello. To collect detail data from cisco router I have to enter some commands, and on of them is: #interface gig 0/0 # ip route-cache flow Question: if there are a lot of subinterfaces Will I have to enter this command for every subinterface or it will be enough to enter this command to main interface?

64<->32bit replication / Win<->Linux collectors?
Regarding Enterprise Edition, is there any issue with running the main server on a 64-bit Red Hat Linux machine and having the secondary server on a 32-bit Ubuntu machine? Will the MySQL replication still perform as usual? Also, is there any issue with a Windows-based remote collector reporting to a Linux main server? I wouldn't expect any, but just want to make sure. Thanks!
nfa6.5 enterprise 64bit: utilization alert
Hi, all over the day i get emails about utilization alerts of an interface. But this can't be right. We have a bandwidth of 34mbit, which i configured in nfa, too.

Peaks in Graphs and Raw-Data
Hi there, we are currently using the Free Version of NetFlowAnalyzer with a Cisco 12000 with 2 Interfaces. We have different counters, one of our Provider, one via SNMP (Cacti) and of course the one with netflow. Normally we have about 50MBit - shown on all Graphs. But in last time we get as much requests that parts of our network is down (DOS). We can identify the source IPs an taking action against. But if I look at the Graphs in the netflow analyzer, there are many big peaks. All other Graphs/Coutners
nfa6.5 enterprise 64bit: No data available...
Hi, i have the following problems: if i look on the server dashboard i get the message: No data available for the last 1 hour. if i choose a router in the device group, all the devices have 0.00bps traffic in/out. But if i choose an interface i can see traffic in/out. if i open the collector-frontend and select a router, i can see the traffic too. I tried a reload of the server/collector --> without success I restarted the system --> success for about 1/2h --> traffic again 0.00bps Can somebody help?

some design-improvements for nfa 6.5 enterprise
Hi, I have to write my suggestions for improvement here, because your FORM at manageengine.adventnet.com/products/netflow/distributed-monitoring/need-feature.html doesn't work. Especially the red line at the verification code is really nasty! we have the nfa 6.5 enterprise 64bit. So here are my improvements: Here are some design-improvements 1. although the collector has an alphabetical order of the devices AND interfaces, the server don't have it! So its really hard to find the right interface.

NFA Beginner
Hi, I have installed a Free Edition of NetFlow Anlayzer and would like to analysis the traffic and bandwidth monitoring for at least one interface before we get the new licenses. Can some one guide me what's the next step in order to achieve my target? What changes or steps should be done at router or switch level (with an example), so that the NFA can collect data and represent in reports and dashboard view. Any help is appreciated. Thanks in advance. Kris
