Netflow/sFlow data collection
We are running trial of Opmanager & Netflow and have several queries We have a Black Diamond 6808 which is current set up to send sflow traffic but we are not seeing any at the NFA end? How can we check the setting on the black diamond or reconfigure them to send to the correct listening device? In the Opmanager interface will we see NFA options available in the device snapshot screen or do we have to open the NFA web interface? Regards Mark
"Schedule Reports" ZIP Format - Any Other Options?
Unfortunately for me, our organization does not permit ZIP files in email due to viruses and worms which had used them in the past. I'm running NFA 5.5. It has been this way for years and the organization has survived. I do not believe it will change. Now, this process is not intelligent, it only looks at the extension, it does not have intelligence based on what the attachment is. Outside of the NFA application, I get around this by simply adding a new extension. Is there some script file I can

Software Netflow Probe for LINUX
Hi, I have read through these forums and cannot find any substantial discussion on solutions for software Netflow probes on machines with a single NIC. We are running Debian and have been running fprobe for some time. Our servers have one interface each. (one NIC per server, eth0) We have previously only been using CUFlow for reporting. I have now installed NFA and it seems great. It does everything we need. However, NFA is combing the incoming and outgoing data and counting them both as incoming.
Inaccuracte traffic figures

mySQL data
-I have installed Netflow on my server... -The system partition where the app is installed is filling up fairly quickly due to data fed into the mySQL database that was loaded with the app. -Can I move this database to another partition on the server and if so how is done [step by step procedure]. If not do I need to do a reinstall and install it on the partition that has ample amount of disk space? Also...is there an option to utilize MS SQL instead that is located on another server? How would I
How many interfaces ... and how calculate IN/OUT-Application
Hi NFA-Team, how many Interfaces (i mean the maximum!!) i can observe in NetflowAnalyzer (Enterprise-Version and Professional-Version). I need the maximum number of interfaces for both versions . And second ... how you calculate the netflow IN and OUT traffic?? I mean netflow is just unidirectional.. I know that you get a formula to calculate the BandwidthUtilization, but how you know what is an Incoming-Application and what is a Outgoing-Application? The formula get just the in- and outOctets and

Flows stop and never restart
I have roughly 25 devices being polled and some of the flows stop. Nothing in the config changes, but Netflow analyzer shows an abrupt end of the data. Another thing is on some of the devices where Netflow stops, you can still see NBAR data. It's becoming a problem when management asks for data and I realize the data isn't there. Any idea what's causing this?
IP SLA Feature-Any plans for it?
I need IP SLA data and there's not many products to choose from. Any plans on incorporating it into the Netflow Analyzer?
mysterious port # change
This is the second time that this has happened on one of my routers and I don't have a clue as to why. I've installed Netflow as directed with the destination IP and port 9996, but then a few days later I notice that I'm not getting any flow from a router. When I look at it's config, the port number has changed to 2055. Any ideas of what would cause this? Thanks
Not receiving any flow
Hi All, I had Netflow running perfectly until the server run out of disk space and I was unable to start it anymore. I have moved the directory /opt/AdventNet to a new server with a bigger hard disk and was then able to start again the Netflow application. After moving the netflow directory to the new server Netflow is no longer receiving flows from the routers. I don't want to do a fresh installation as I want to keep the history. Can you please advise what could be done to fix this problem. Thank

graphs not updating
I have had no problems with this software for the past week. Today I noticed that the traffic graphs for both interfaces stopped updating about 8:30AM CST. The application graph stopped updating at 8:20AM CST. It is now 8:55AM CST. I stopped and restarted the netflow service but that didn't seem to help. Any ideas?
IP Grouping - % Calculation
Hi, Great Product by the way. We currently have a WAN ring in place between all our sites, this runs at 100Mbps all round. We have approx 20 Routers exporting flows. I have setup IP grouping for the differnt Areas of the Business. When i look aty the Stats and it give me a reading that for example Acconuts are at 90% out traffic, does that mean that the total amount of traffic on the WAN at that present hour is 90% of traffic from the accounts department?? Cheers,
modify the ifSpeed for more as only one IF
Hallo, can i change the ifSpeed for more as only one IF in one time? for example: we have many vpn-channels and the ifSpeed for this virtual interfaces are 9000bit. but real is the speed same the speed of ethernet-interface. this 9000bit-string is just for the boot-process and set the best routing path in the first time. (2 vpn-channels on 1 ethernet, first is the main path and better ifSpeed and will be set for routing, second is the backup path and have lower ifSpeed) after the boot-process the

Netflow doesnt seem to identify Interface in Router
I'm using Netflow Analyser 5 to view traffic on a cisco router with 2 Serial interfaces and 1 ethernet interface. Currently it tracks one serial and 1 ethernet interface. I dont know why its not tracking the second serial interface, What i tried is, went to the license management, made the Ethernet to unmanaged, so as to make one license free But i still dont see the second serial interface, not sure where the problem is since it detects 2 interface but not the third one. let me know what i should

Traffic Graph in excess of circuit size
For a given circuit (OC3- 155Mbps), the graph regularly records spikes well in excess of the circuit bandwidth: Category Total Max Min Avg 95th Per Traffic OUT 147147.42 MB 581.02 Mbps - 46.71 Mbps 99.05 Mbps I'm confused. Is this sent data over the circuit size dropped, or is this an error in how the data is captured or displayed?

Features Required
Hi, I have been evaluating ManageEngine Netflow analyzer and Somin Scrutinizer NEtflow analyzer and found there is major gap in features. I think manage engine cusomers need more features than what is present now like 1. Real time statistics for Top Talkers / Top protocols / Top conversation 2. Long lived data 3. Network Map which changes their sign depends on the traffic flow 4. Alert should be generated and sent with the Top Talkers in the mail body 5. i dont think Sflow may be appreciated by many

In Enterprise-Version the languare is mixed
Hi, we test both versions of NetflowAnalyzer. In the professional version, the languare is set correct to german (can we switch to english?).

95 percentile calculation and more
Hi, 1. Could you please explain in more details how you calculate 95 percentile? It seems to be not correct and you taking in account only active samples during reporting period - the correct calculation should take in account all possible samples even if there is no traffic at measured time. For instance when calculating 95 percentile for weekly report and using 1 hour table we have 24*7= 168 time intervals so you should sort traffic samples for this interval in descending order and the value corresponding
mystery ip conversation
hi all. I've create an IP group which is basically non-private ip space. When i view the conversations in this group, I see lots of data from ip's that are in the public space, specifically between: 8.0.69.0 and 2.64.10.x. I don't see these IP's when i check the conversations on any individual interface being watched. I think i have either an error in the way i set up the group. Can someone enlighten me as to how the netmask is used for the IP range? I would have expected a start and end ip, but

Another newbie issue
I have a Cisco 2600 hooked to my firewall. I configured the 2600 via serial cable. I set the desitination/port and set the source. Changed the version to 5. I can see data via the show ip flow export and show ip cache flow commands. For some reason though I can't get Netflow Analyzer to capture the data. I setup a rule on my firewall to allow UDP port 9996 through to this server but still no luck. In fact I can't see any traffic across my firewall using that port. I'm not sure what to do next for
