Using Netflow Analyzer on VMware
Has anyone used vm for either collectors or central server? We have a push to remove standard servers and move onto VM's.
AS Collection
When I go to view AS Collection information (tab: Autonomous System View) the one hour period always shows "no as data to display for selected time period", if i select 'last 6 hours' from the pull down, i see the expected results. When I evaluated the software, the trial version would show the AS info for the 'last hour' selection. When we purchased the software i installed it onto a new machine. I've not seen the 1 hour AS data since. any idea what i might need to tweak to see this working
Help understanding traffic graphs
I have been assigned to take over monitoring our bandwidth. We have NetFlow Analyzer set up to monitor our edge routers. I am having a hard time understanding the traffic reports. In particular I want to monitor bandwidth utilization between one of our firewalls and a remote site. Al traffic is through an IPSEC tunnel. The far end is a 10Mb connection and my end is 200Mb. The IP group is set to include the IP address of the far end of the VPN tunnel. If I go to the IP Group -> Traffic -> Speed
Configuring NetFlow Analyser
Hello, Am a new NetFlow user with little to no experience about how to configure routers and ports etc to send bandwidth data to the central server. Would appreciate anyone with the experience to offer some advise on how i can set up all our routers to send usage information and to the NetFlow server and also be able to generate and/or send graphical usage diagrams. Many thanks, Kind regards, Jericho
HTTP Status 500
I have installed NetFlow on my linux server under root and it looks like it is collecting successfully. I can log into the app using http://[IP]:8080 and when I click on the "One Min Graph" on the Interface View then there is a Java error shown below. Also when I click IfIndex# interface nothing is displayed. HTTP Status 500 - type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException
# of interfaces
We are currently a OpManager customer and are looking to add NetFlow analyzer. We will be using a passive fiber tap to mirror our 4 Gig-E Internet uplinks into a couple of boxes running Linux, which will then run the open-source pmacct tool. This tool will take the mirrored traffic and then convert it into a NetFlow v9 stream and send it to the collector (in this case, it would be NetFlow analyzer). We will do this across a total of 4 Gig-E router interfaces, so I assume that means I only need

Enabling NetFlow on Cisco ASA via ASDM
Hello, I recently became the System Administrator for a small company and I would like to get a grip on our network. A friend recomended Netflow Analyzer and from what I can tell we could really use it - but I'm not too familiar with working on Cisco devices. We have an ASA5510 that does all of our VPN, firewall and routing. In reading the installation instructions for Netflow there are a few commands that need to be run on the ASA device but I also read that I could use the ADSM to configure the

Recommended Sampling rate for Adtran routers
Our company recently purchased Netflow and are trying to analyze Netflow data that is being exported to the NFA collector. By default, the Adtran samples every packet. When we view the data in 1 minute intervals, it appears to be way off. Do you have any recommended settings for Adtran so the data is accurately represented?
Installation Net flow analyser
Hi, We need to install Net flow analyser into our environment. Currently we have Solarwinds Netflow Analyser. Please answer below queries:- 1. Please provide us detailed hardware / OS coniguration required for installation of manageengine netflow analyser. 2. If we will remove Solarwinds Netflow analyser and install manageengine netflow analyser then it will capture all interfaces automatically like Orion netflow analyser or it will require manual addition of each device/inteface to monitor traffic.
individual conversation graphs not working
Please see the attached screenshots. If I try to view a graph of an individual conversation, the graph doesn't show the lines for the data. Exporting to a pdf also doesn't show the actual line on the graph. The Main graph regarding all flows on an interfaces shows correctly, but when you drill down and find a user that is using a large amount of data, you can't generate a report on it.

Configuring multiple hosts behind NAT
Hi There, I'm trying to configure multiple hosts behind a single NAT'ed public IP to report into an external collector. I am however only seeing one of the three devices reporting in. I'm picking that NetFlow Analyzer may be detecting the same interface name, or something to that effect, as the three devices are behing a single NAT'ed public IP. How is the configuration of devices behind a NAT'ed IP recommended for NetFlow? Any help would be appreciated Cheers Frazer

How to use Netflow Plugin..?
We have installed netflow plugin on top of OPManager but when I tried to access the Netflow analyzer, it is saying that I should enable the Netflow/Sflow on the device or No such device with Netflow/Sflow export is found. What can be the error? Can I use netflow Plugin for Juniper Firewall or is it only for switch/router?How can I configure thge device to obtain the data using the Netflow plugin? Also can we use Netflow Plugin for IPSEC VPN Monitoring? Help is very much required at the earliest...
Issue With Netflow Conversation
Hi, We are running Netflow Analyser 8.6 monitoring a mixture of MPLS and ADSL routers. We have an issue on our ADSL routers, they are Cisco C837s. We see three interfaces in netflow; virtual-access, dialer1, and Ethernet0. The ATM and Dialer interfaces report inbound and outbound traffic respectively and the Ethernet interface reports inbound and outbound. We only wish to Manage the Ethernet0 interface and monitor both directions. The issue is that on the Ethernet interface the Conversation is the
QoS not bing displaye correctly
Guys, Hope you can help, We have and MPLS network across 2Mb LL, we have asked our provider to point all the Cisco routers to the Net flow server and after some initial configuration changes we see all the devices. We do however still have a few issues: 1. The QoS setting do not seem to be working, almost everything is being reported under "000000", and Again QoS has been configured on these routers by our Provider. 2. I had to manually change the interface speed to the correct bits,(e.g. 2Mb = 2000000bits)
Two PFsense routers and static routes
1 Pfsense box with 3 links. wan ,lan .And opt1 Second Pfsense box same setup Wan ,lan opt1. Both have their own modem and Wan IP Both have a different lan subnet. The pair have a static route configured between them on the OPT1 interface (separate subnet) 1/2 mile apart using wireless AP's to make the link. This works flawless. Both lans have several servers , mostly Security systems with cameras , so we have a lot of internal traffic. I have Pfflowd set up sending data to my trial ManageEngine
