Difference between Windows and Linux Netflow Analyzer Data
We have been running Manage Engine on Windows for a few months and are very happy with it. We recently started switching to linux servers and decided to try Manage Engine's linux version. We have had both the Windows version (8.5) and the linux version (8.6) collecting data at the same time, being fed by the same device. I have noticed that the windows install seems to consistently have larger data totals, for instance: last week the Windows server recorded 145.48 GB of data transfer, but for
Can I see packet loss with NetFlow Analyzer?
I would like to see packet loss on my interfaces that are being monitored, is this possible? I have looked at all the reports and such that I can find and I can't see to find where this is. I am running NetFlow Analyzer 8
Netflow ManageEngine_NetFlowAnalyzer_8600.bin on a 64bit server.
Is there a workaround for getting ManageEngine_NetFlowAnalyzer_8600.bin to function on a 64bit Linux host?

Total Bytes calculation vs SNMP tools
Hello, I am using NFA in a router that is polled by another tool. NFA is reporting for Netflows informations transmitted by the router (Cisco) in the WAN interface (ETHERNET). The other tool is collecting data every 5 minutes on the same interface. Excluding 5 minutes polling vs continous flow issues, I am comparing daily volumes on both tool with BYTES IN and OUT for a day. The SNMP tool calculate 36.3 GB IN and 6.5 GB OUT. NFA reports for 34.8 GB IN and 5.7 GB OUT. Can you tell me how the NFA is
Unaccounted or no data
Hi, I am using the 8.5 Porfessional Plus Netflow and have the following problem: All my data shows as “Unaccounted” in the Application, Source, Destination. And the Conversation tab doesn’t show data unless i set the time filter to “Last 6 Hours” and above. If I set it to "Last 15mins" or even "Last 30mins" it just shows as "Unaccounted" and the conversation shows nothing. Please help with this.

Netflow Analyzer Pro 8 - Export Application Mappings & Reports
Our company was recently purchased and we are in the process of moving our Netflow Analyzer Pro to a server at the new corporate headquarters. I would like to know if there is a way to export the Application Mappings and Reports to the new server, but nothing else. We will be monitoring new devices and we want to start with fresh data. Can this be done or should I just move the database and then delete all of the devices and start fresh. Please advise. Sincerely, Matthew Linsemier The Doctors

Configuring Email Notification

Netflow plug-in SMTP ???
Netflow I have little problem when Netflow plug-in SMTP to send the report but could not find the SMTP settings changed ???
T1 reported rates are incorrect on WAN interfaces.
I am getting spikes way above 100% utilziation rates. The interface in NetFlow Manager is set to 1536000 bits per second (full T1 speed). The serial interface on the routers are set for frame relay. Bandwidth and the clockrate are set at the frame switch. Is what I am seeing in the reports reliable and correct? It seems not based on the fact that I would think that you can't have utilization rates above 100%. Any help in this matter is greatly appreciteated.
Including Scheduler Name & Description in generated report headers
Hopefully this isn't an "RTFM" issue (I did go looking !)......... Perhaps just a detail, but it'd be useful to those of us who aren't using reports on a daily basis, or who are trying to explain the report information to someone else. It's certainly nice to have the group name, but that's only meaningful to the techies who set it up; it's not so useful to the managers who are being asked to act on the information in the report. D.
Report Netflow
-When the bandwidth of the transmission report, if received reports by the only graphic pdf files, if using excel file, there is no graphic that showed the number of traffic in or out, no way just a graphic report both the number of printed or out traffic. -You can report the same information as the first report did not? (ex: Traffic, Total Transferred bytes, packets per second) -If the instructions on how to do Thank you

Is it possible to convert our flows in files *.flw to format of NetFlow Analyzer?
Not long ago our company purchased Opmanager Opmanager, and now my authorities are thinking of purchasing NetFlow Analyzer. But the situation is as follows: We have already used for the last year some free stuff - flow-tools. And all our traffic is gathered in these *.flw files. Is it possible somehow to convert these files to Network Analyzer? May it's some kind of script or so on? Thanks!
Custom Report - Link Peak's
I am playing custom reports.... however I am pull a report on an application it gives me the traffic for the period (ie 4.4GB) I asked for ie the last 30 day's.

In NetFlow Analyzer can we define a name to an IP address so that reports show the name instead of the IP address?
Question about 1Minute average graph for a 2M E1 link
Hi All, I get a interesting finding that on the traffic volume shown by the netflow analyzer when comparing with our MRTG graph. We have a router interface connecting a 2M E1 link. From our MRTG workstation, the max. interface bandwidth is aroung 1.8Mbits. When we compare the data with our Netflow analyzer (v8.5), the one minute graph show the average bandwidth is over 30Mbytes... 2M link’s theoretical max. throughput (one minute) is 2M x 60 = 120Mbits (i.e. ~ 15Mbytes), but the figure in netflow

IP forwarding - report client IP address rather than McAfee Web Gateway IP
Is there anything that needs to be done in order to capture and report the client IP for internet traffic rather than the IP of our web filtering server? We enabled IP forwarding on our web filter and it's using the default 'X-Forwarded-For' header. Thanks, Ryan
alert for free disk space

The top stats page says "no data to display"
We have been testing the Netflow Analyzer Professional Plus for about a week. The various pages have been populated with data. We have been especially interested in the "top stats" area of the dashboards. We came in a day or so ago and the top stats page says "no data to display" in the all of the "topxxx" windows and the graph has no data in it. The Network snapshot screen appears to have data in it. Please see screen shots in attached file. Thoughts? Thank you, support@colfaxnet.com

Netflow Analyzer Top Protocol Widgets incorrect
Hello! In Netflow Analyzer 8.6.8600 i see dashboards with Top Protocols for last 1 hour (screenshot in attachment), 78% + 37% + 4% + 3% it's bigger than 100%. I understand why i see such statistics.
Netflow Analyzer speed graph seems aggregated 2 minutes loads
I intentionally created a load for about 2 ~ 3 minutes, with active flow timeout set as 1 minute on Cisco router, to confirm what I will see on NetfFlow Analyzer. I expect the graph shows me trapezia shaped spike, but what I got was a pretty trianlge spike across that 2 minutes. As shown in the attached JPG, all load instances appeared as triangle spike across 2 minutes... Any idea what might causing this issue? I try to create this test, the overall graph shown looks quite different to MRTG.

Configuring SSL for Netflow
I have install/configured NetFlow and it runs fine on port 8080, however, after following the instructions to configure SSL on port 8443, I have come to a dead-end. It seems NetFlow fails to listen on 8443. When a do a' netstat|grep 8443', nothing show up. I generated the server.keystore certificate and stored it under $NetFlowHome/server/default/conf. Any thoughts/suggestions will be appreciated! Thanks in advance.
analyzer stops collect data
Hi We have installed netflow analyzer 8600 to centos 5.5 64bit os. database tuning is made according 4gig ram Our L3 switch (catalyst 6500/sup32 with adventerprisek9_wan-mz.122-33.SXI2a) sends flows correctly to server. When we send version 5 with AS info analyzer stops collecting data after 5-15 minutes When we send version 5 data without AS info the collecting time can be 1-5 hour. In both cases analyzer reveives about 3600 flow per second. When we switch to version 9, only ~ 10 flows is received
Live QoS Traffic Reports
Hi There I'm new to NetFlow Analyzer and so far i'm liking it, but can you tell me where i can add a live traffic report on a dasboard based on QoS markings? Basically we mark trafic for two destinations based on BGP feeds, and they are accounted for seperatley. Email alerts for link saturation based on DSCP markings work, however i'd like to see a live traffic report similar to the total utilization reports, but based on QoS, specifically DSCP markings, or ideally the configured DSCP groups
Fortigate and Netflow interface statistics do not match
We are running version 8.6 of Netflow Analyzer and collecting data from a Fortigate 310B using sflow. When I verify the LAN interface statistics (14h30) directly on the Fortigate, it shows the interface at approximately 35Mbps. When I verify Netflow Analyzer for the same period, it shows 200 Kbps. Fortigate 310B is running V4.0 build 0291 Thanks,
