Keep Raw data for longer time for later query
Hi, How can I make the unaggregated raw data for a long time so we can query against it later? At this time, NetFlow seems only keeping the raw data for one day, after that the data are aggreated. We'd like to keep the raw data for , for example, up to 3 months. Any easier way to accomplish this? Thanks, A NF user

Alert Profile Management
I am having problems with the Alert Profile Management. It does not seem to generate any alarms or send email when the traffic utilization exceeds the threshold. for example I have an alert profile that should generate an alarm if the link is 45% utilized 5 times in 5 minutes. Sometimes the link reaches 80% and nothing happens. Thank you Ramzi

Statistics errors
Hi, in attach you can find two file .pdf (report generate with netflow analyzer software v.5.). I try to explain the problem: 1) in the file filiale_1.pdf, the MAX traffic value is 1,22 Mbps. This serial line has a PCR (Peak Cell Rate) of 768 kbps and for this the value is wrong; the max peak cell rate should be 768kbps maximum. 2) in the file filiale_2.pdf, the MAX traffic value is 4.13 Mbps . This serial line has a PCR of 2048 kbps and for this the value is wrong too; the max peak cell rate should

bad traffic statistics with netflow
We are trying netflow analyzer on a 6509/sup720 running in hybrid mode. I have tried exporting nteflow stats on layer 2 and layer 3. The amount of traffic that it is showing me is way low for all interfaces. What am I doin wrong? I realy only want to monitor one interface for now. I know this interface should be running at about 10meg in and out all the time, but I'm seeing stats of 10kb in and out of this interface. Below is the config on the layer 2 side I am using: set mls flow full set mls nde

Installation
Hi Raghu If we want to install a probe in each location and pull the data to the centralised server . So that the traffic during core business hours is not affected at the same time we can pull the historical data. 1) is this topology possible. 2) is it possible to shedule the replication. 3)what is the licensing scheme for this option. (We already purchased the software for Earnst and Young)

IP Groups and device stats do not add up (5.5EA)
Hi, I am currently running version 5.5 EA and have the following problem. I have setup a number of IP Groups mostly containing single IP address which are then being used in the scheduled reports so we can do billing. I have been comparing the figures with our current billing system and all seems fine, but then I noticed that if I enter the interface which all this traffic is for and goto the destinations tab for the same time period as the IP group they show different figures. The one on the interface

Capturing MFR Subint Traffic
Hi, in analyzing this tool for purchase, we noticed that we are getting some strange readings that we can't understand: 1. We've enabled IP Route Cache Flow on our MFR, and have added the ingress and egress statements on our MFR.500 subint. However, we're only getting valid traffic on the "ingress" statement, and no traffic on the "egress". Our other router is working fine. Is there a particular way that the ingress/egress statements must be applied to the interfaces to make this work (i.e. individual
Is it possible to analyze host header info using NetFlow?
Was wondering if there is any way to get NetFlow statistics that are routed to individual web sites all sharing the same IP address. For example, I have 30 web sites on a single web server all using the same IP. Web requests are routed using host header info. Any help would be really appreciated.
Structure of the MySQL Database
Hello, we'd like to do some automated calculation of the flow data by several scripts i.e. all traffic volume per ip address. We would like to use the MySQL database of NFA directly because the flow data is already there. I found some tables (i.e. Conversation24Hour or Conversation10Min) that seem to hold the information we need but when I do a query on that table and compare the total amount for a given timeframe with the the total traffic of NFA for the same timeframe there is always a difference.
Juniper Routers
Does someone use Netflow Analyzer with Juniper Routers? I'm testing it and I use a sampling rate of 10. That means that I'm recieving 1/10th of the packets and that's why I'm seeing 1/10th of my traffic. Does someone has a solution for this? The percentage does work, because I've set the bandwith on the routers. But the actual data isn't the real data. Gr. Edwin

Few Questions
We have configured all the router to using Net flow to push the traffic to net flow analyzer server, we are not using SNMP/NBAR. 1. We have got one physical interface on few routers, after enabling the net flow on the physical interface; we got to see two interfaces on the web console, which is confusing. Does it show an interface for in / out separately? 2. After enabling it on our main router , we got to see some links displaying IN/OUT traffic, but few links showed up with only IN traffic, which
