NetFlow Ubuntu 32-bit Installation Problem
I have just finished installing the NetFlow Analyzer demo on an Ubuntu 32-bit server for evaluation. The install went fine from the command line but when I try and run run.sh I get the output that is quoted below. I tried running as the logged in user as well as root. The app was installed as the regular user. Also of note, I changed the ports during installation. Web port is 1257 and netflow port I changed to 2055.

device not added even when it send flow data
Hi, i have a problem with a new cisco device. I have replaced a cisco router (2811) with a new one (ASR1001). The new router (ASR1001) is exporting the flow data propperlly. However the netflow anylzer does not re-detect all new interfaces. As the redetection did not work I've deleted the router from license management since it should be re-detected again when the netflow analyzer receives flow data, but the router is not added too. I hope some one can help me Thx

SNMPv3 error - Credential Not Applied Due To:usmStatsUnknownEngineIDs

Monitor session on Layer 3 switch
Hello, I have netflow running on all my routers on my network but some sites have a layer 3 switch so I bought 3 nbox nprobes to mirror the port and send data back to the netflow server. They are all working ok but only reporting 1 mirrored port back to the netfow server. I thought on a cisco switch you can have two monitor sessions Has anyone else had this problem? Is it an issue with the cisco setup of is something blocking it on the netflow server. regards, Kevin

Traffic Rates Inaccurate
I just set up Netflow Analyzer to capture data from our Juniper SRX firewall. I used the recommended settings for Jflow (with some modifications due to code differences) from the documentation but it appears to be off by a factor of 10. For example, Netflow is reporting traffic rates between 50-100Mbps: https://i.imgur.com/qTQU5CS.png. However, this interface is only connected to a 10Mbps internet circuit. Here are the traffic graphs from the device itself: https://i.imgur.com/UQASw7j.png. Here's

No OUT traffic appearing
Hey Everyone, I am evaluating NetFlow Analyzer in conjunction with a Fortigate setup in order to track the bandwidth usage on both the upload and download of each port of the Fortigate. I have enabled Netflow support on the fortigate inline with the documentation on your site and NetFlow Analyzer has been very accurate in tracking the download usage (ie IN traffic) but no OUT traffic has been registered whatsoever. I have enabled Netflow on all the ports (WAN and LAN) and still no OUT traffic. Any

Using NFA Free/Professional Edition. I've looked on Google and the forums for this. We use a Microsoft CA and I've got a .PFX file that I copied into the NFAHOME \conf directory. I modified my server.xml file like the following: keystoreFile="./conf/nfa.pfx" keystoreType="pkcs12" keystorePass="mypassword" I have verified with keytool that the certificate as well as the root is in the pfx file. Everything appears in that when I go to the site the certificate shows properly. However I noticed that

ifindex and not all interfaces and too many interfaces
NFA version 9870 Cisco 1841 NFA shows my Serial0/0/0 interface fine but either doesn't show or make available all subinterfaces or has some of them as ifindex values and when I go to the "New" interfaces tab there are like 50,000 ifindex values. This causes NFA to slow down alot. I have the snmp persist ifindex so that doesn't change. I ran the snmpwalk batch file using the parameters in NFA and it works fine, showing all the correct interfaces. Here's a partial output of snmp walk. In the interface
Problems with flexible Netflow, IPv6 and QoS
Hi, running netflow analyzer distributed edition version 9.9 (9900) on linux. We have been using netflow analyzer with traditional netflow for some time and it has worked great and been very helpful in identifying what traffic goes in what QoS class, performance etc. However; after we started upgrading our sites to using both IPv4 and IPv6 we had to convert the netflow configuration to flexible netflow due to problems with how netflow analyzer was parsing the data (we had a support case filed on

Strange traffic in NetFlow Analyzer
Past few days I've seen the following traffic. The source IP addresses look strange to me and the destination addresses are to difference places and countries that aren't part of our network. All this traffic gets blocked by our ACLs on our router. But it looks strange. And the protocols are old routing protocols and I think monitoring protocols. And the size of the traffic is always 805.31 MB.

What's NEW in NetFlow Analyzer
Hi All, NetFlow analyzer now sets up a new standard,yet again. A lot new features has been introduced to aid solve Network admin's challenges. ManageEngine Processes 100k Flows/Sec with NetFlow Analyzer v10 This marks a 10x improvement in scalability for NetFlow Analyzer, which previously handled up to 10,000 flows per second with raw data storage.

NetFlow IP addresses
Hi Long story short, I have two interfaces in my ASA which I am monitoring. Everything works but I don't see the IP addresses when I go to Source, Destination nor Conversation. I clicked Resolve DNS but don't see the IP addresses I edited the Interface parameters and used 8.8.8.8 DNS and for a few minutes I could see the IP addresses but after a while they disappeared again. What am I doing wrong? All inputs are appreciated. Please let me know if you need more info, thanks!

Netflow on multi context cisco asa
Hi All, We are using cisco ASA in multi-context mode. So we have created two port-channels and 2 ports are assigned to each port-channel, then we have created sub interfaces of port channel and have assigned them to multi-context ASA. We can configure netflow under each context but what we are looking for is to configure netflow under system context so that we can see total amount of traffic hitting on the port-channels other than traffic hitting on port-channel sub interfaces under each context.
Can the Alert Reports sent from Alert Profile be adjusted?
We have recently deployed Netflow Analyzer and I have been playing with the Alert Profiles as being able to receive an emailed summary of what source & destinations are generating high traffic loads is a real time saver for us. One thing I have noticed is that the report that is sent tries to cover a period 10 minutes before & 10 minutes after the event. This could be useful but most often the report is sent so quickly that there is no data for the 10 minutes after the event as that time period
NFA can't integrate with OPM probe
Hi All, Today I found an issue on integration between OPM Probe and NFA, we couldn't see any application traffic on Interface GUI of OPM device snapshot. And I made sure that the device has enabled Netflow and we can see the traffic and application of it on NFA GUI. So I navigated to OPM Probe integration setting and re-entered the credential of NFA. Then it gave us error that "Unable to connect NFA server". OPM version is 9101 and is deployed with Central-Probe, NFA version is 9600
