We just installed a Cisco ASR 1002, The old net flow commands used in our 3845 do not work. Has anyone set configuration to export Top-Talkers?

Thanks

I dont suspose this decision is likely to be reversed? My issue is that now to upgrade to 4.4 I need to go and request a budget for SQL licensing or stay stuck on 4.3 for the forseable future.

In my view MS SQL just adds to the cost of the product (which, whilst Solarwinds is a strong and good product and one I do recommend, its not a cheap solution to begin with), I understand Solarwinds does say that NPM and NTA can share the same MS SQL DB to me this feels like its a step back and that the performance overhead for NTA has been added back into the DB for NPM.

Ideally it would be great if Solarwinds could consider moving to an appliance based approach running on linux/mysql making it easier to deploy and (for us admins anyway) maintain and cut the dependency on MS products.

Due to our VRF design and SFLOW limitations on the Cisco Nexus 9000 switches, I need to send Sflow datagrams to NTA from a different source address than the managment address NPM uses to poll the switch. NTA sees the traffic, but lists the source as "unknown" since the IP address is different. Any ideas?

I am running into wall after wall with both Cisco and Solarwinds support.  It sounds like the packet capture on the ORION server is showing that I am missing a "valid interface index" under the flow record template in the ASR.  I can't find what that commnand would be.  Here is my current config on that ASR920.  Support also saying that I am missing:  "OUTPUT_SNMP" or "OutputInt:_ " - not sure what this translates to as far as a Cisco command to put under the flow record.  Dang, why does this have to be so confusing?  Thanks for any suggestions everyone!

I've been asked by our Security team for reporting on our internet connections.  They want who's going where and for what content.

First, I would think that a report like this should already be available.  It seems like a no-brainer to me 

However, the canned web console reports don't have the ability to filter to specific interfaces, and Report Writer doesn't have any NetFlow data sources.  I find this ridiculous at best, and aggravating at worst.

What's the point of having all the NetFlow data if I can't report on it?

Has anybody else faced this situation?

Hi,

I configured netflow on cisco router 2921 and here is my config..

ip flow-export source Gigabitethernet 0/1

ip flow-export source Gigabitethernet 0/2

ip flow-export source Gigabitethernet 0/0

ip flow-export version 5

ip flow-export destination 131.x.x.x 2055

I also configure this on each interface

Interface Gigabitethernet 0/0

ip flow ingress

ip flow egress

ip route-cache flow

Interface Gigabitethernet 0/1

ip route-cache flow

Interface Gigabitethernet 0/1.55

ip flow ingress

ip flow egress

ip route-cache

Interface Gigabitethernet 0/1.56

ip flow ingress

ip flow egress

ip route-cache

Interface Gigabitethernet 0/2

ip flow ingress

ip flow egress

ip route-cache flow

when I performed show run on the router this is the configuration that appeared:

ip flow-export source Gigabitethernet 0/0

ip flow-export version 5

ip flow-export destination 131.x.x.x 2055

I noticed that the last source (Gigabitethernet0/0) that I typed was the source that was registered on the router

What could be the effect of this configuration?

Gigabitethernet0/1 and Gigabitethernet0/2 are on the public side of the router,I want to monitor the traffic that is going in and out of these interface because I have vpn tunnels configured on this interfaces (Gigabitethernet 0/1.55 and Gigabitethernet0/1.56) 

Did I enter the right configuration for my router?

By the way my Solarwinds server resides on the Gigabitethernet0/0 network.

Please help..

Thank you very much!

Hi team, I'm trying to find a way of displaying all ports being used (weather or not it is tagged to a Application ) as I our current fleet have their Windows Domain firewall turned off and I want to turn it on.

We have all our floors switches come back to a core switch and this is being stored in solar winds using NTA and Netflow.

I've been working with the report writer and Netflow by connection but it doesn't seem to be giving me what I am after.

Example of report would be like this

Has any one created or seen a report like this and can give some advise on how to generate it as at the moment I'm struggling reaching this outcome

Problem

I was looking for an alternative to NProbe as a NetFlow Probe/Agent for a CentOS as NProbe is not free and i wanted somehing that i could run as a Probe only and in deamon mode.  After looking at various options, I settled on SoftFlowD as an alternative and thought that I would share with the community how exactly I did it.  It works like a dream for me so enjoy!!!

Installing SoftFlowD as a TCP Flow Based Probe

The following is a description of how we can install a TCP Flow based probe to capture the data going in and out of a Centos Linux server and to export this in NetFlow Version 5 format to a collector for further analysis.

First of ak, we need to ensure that we have a few utilities installed on the server to satisfy the dependencies.

[root@wbcphpxy01 ~]# yum install libtool automake autoconf python-devel

libpcap-devel

Once these are installed, then let’s get a copy of the softflowd compressed source files:-

[root@wbcphpxy01 ~]# cd /root

[root@wbcphpxy01 ~]#wget http://softflowd.googlecode.com/files/softflowd-0.9.9.tar.gz

Now let’s decompress them:-

[root@wbcphpxy01 ~]# tar -zxvf softflowd-0.9.9.tar.gz

configure: creating ./config.status

1. config.status: creating Makefile
2. config.status: WARNING:  'Makefile.in' seems to ignore the --datarootdir setting
3. config.status: creating config.h

Now we need to run the make utility to build a binary executable ready to install, which is customised to your environment:-

[root@wbcphpxy01 softflowd-0.9.9]# make

gcc -g -O2 -DFLOW_SPLAY          -DEXPIRY_RB             -I.   -c -o softflowd.o softflowd.c

gcc  -o softflowctl softflowctl.o convtime.o strlcpy.o strlcat.o closefrom.o daemon.o -lpcap

Now that we have a binary ready for installing, we just need to install the application on your system:-

[root@wbcphpxy01 softflowd-0.9.9]# make install

[ -d /usr/local/sbin ] || \./mkinstalldirs /usr/local/sbin

[ -d /usr/local/share/man/man8 ] || \./mkinstalldirs /usr/local/share/man/man8

/usr/bin/install -c -m 0755 -s softflowd /usr/local/sbin/softflowd

/usr/bin/install -c -m 0755 -s softflowctl /usr/local/sbin/softflowctl

/usr/bin/install -c -m 0644 softflowd.8 /usr/local/share/man/man8/softflowd.8

/usr/bin/install -c -m 0644 softflowctl.8 /usr/local/share/man/man8/softflowctl.8

[root@wbcphpxy01 softflowd-0.9.9]#

Now that we have a working copy of softflowd on the system, we can review the help file for the application by typing the following:-

[root@wbcphpxy01 ~]# softflowd -h

-i or -r option not specified.

Usage: softflowd [options] [bpf_program]

This is softflowd version 0.9.9. Valid commandline options:

  -i [idx:]interface Specify interface to listen on

  -r pcap_file       Specify packet capture file to read

  -t timeout=time    Specify named timeout

  -m max_flows       Specify maximum number of flows to track (default 8192)

  -n host:port       Send Cisco NetFlow(tm)-compatible packets to host:port

  -p pidfile         Record pid in specified file

                     (default: /var/run/softflowd.pid)

  -c pidfile         Location of control socket

                     (default: /var/run/softflowd.ctl)

  -v 1|5|9           NetFlow export packet version

  -L hoplimit        Set TTL/hoplimit for export datagrams

  -T full|proto|ip   Set flow tracking level (default: full)

  -6                 Track IPv6 flows, regardless of whether selected

                     NetFlow export protocol supports it

  -d                 Don't daemonise (run in foreground)

  -D                 Debug mode: foreground + verbosity + track v6 flows

  -s sampling_rate   Specify periodical sampling rate (denominator)

  -h                 Display this help

Now, we should be able to run the software in Debug mode in the foreground using the following command to ensure that we see the relevant messages (especially error messages):-

[root@wbcphpxy01 ~]# softflowd -D -v 5 -i eth0 -n 10.20.30.15:2055 -T full

Using eth0 (idx: 0)

softflowd v0.9.9 starting data collection

Exporting flows to [10.20.30.15]:iop

ADD FLOW seq:1 [10.170.1.201]:1335 <> [10.170.5.251]:22 proto:6

ADD FLOW seq:2 [10.140.42.250]:58374 <> [239.255.255.250]:1900 proto:17

ADD FLOW seq:3 [10.170.5.101]:0 <> [224.0.0.252]:0 proto:2

ADD FLOW seq:4 [10.170.5.101]:0 <> [239.255.255.250]:0 proto:2

...

In the above example, the following explains each of the switches I have used:-

-D                                           Debug mode, which bring this to the foreground

-v 5                                         Version 5 of Netflow

-i eth0                                   The Interface number

-n 10.20.30.15:2055         The target host IP address and port number of the collector/analyser

-T full                                     All protocols

Now running this is Debug mode is useful if you want to make sure that is working but it more useful to have this running in the background so the way we do that is to remove the –D statement in the option like such and you will just see the command prompt come back:-

[root@wbcphpxy01 ~]# softflowd -v 5 -i eth0 -n 10.20.30.15:2055 -T full

[root@wbcphpxy01 ~]#

You can still see that the flows are being “recorded” and that they are being exported in NetFlow version 5 and set to in this case 10.20.30.15 using destination port 2055.  This is done using a utility such as TCPDUMP:-

[root@wbcphpxy01 ~]# tcpdump -n –v dst port 2055

listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes

14:14:01.426775 IP 10.170.5.251.35829 > 10.20.30.15.iop: UDP, length 312

14:15:01.185508 IP 10.170.5.251.35829 > 10.20.30.15.iop: UDP, length 408

14:16:01.944233 IP 10.170.5.251.35829 > 10.20.30.15.iop: UDP, length 168

Now all this is fine, but it really only becomes useful if we can stop/start and restart the application like a service and have this enabled after the server has had a reboot.  To do this we edit a file called /etc/init.d/softflowd and empty the following contents into the file and save it:-

#! /bin/bash

#

# chkconfig: 2345 80 30

# description: SoftFlow Deamon Service

return 1

}

stop_SOFTFLOWD() {

if [ -f ${PID_FILE} ]; then

kill `cat ${PID_FILE}` 2>1 /dev/null

sleep 1

start_SOFTFLOWD;

echo " Done."

;;

*)

echo "Usage: /etc/init.d/SOFTFLOWD {start|stop|restart}"

exit 1

esac

exit 0

After saving the file, we need to change the file permissions to:-

[root@wbcphpxy01 ~]# chmod 755 /etc/init.d/softflowd

Now let’s make the script a loadable initialisation script as part of the “service <application name> start” function by adding this with the chkconfig command:-

[root@wbcphpxy01 ~]# chkconfig --add softflowd

If you need to remove the script from being initiated at boot up as a service, then issue the following:-

[root@wbcphpxy01 ~]# chkconfig --remove softflowd

Finally, let’s start the service:-

[root@wbcphpxy01 ~]# service softflowd start

Start SOFTFLOWD Done.

I have been having some problems getting Netflow setup on our Cisco 3750G swtich stack.

I added the commands below -

ip flow-export source GigabitEthernet1/0/2
ip flow-export version 5
ip flow-export destination 10.0.0.35 2055

I see everything showing up under Netflow, but it seems that Cisco is transmitting no netflow data back to SolarWinds.

I see under the "Last Data Received" column that it says "Never"

What I would like to do is have it submit Netflow data for everything on VLAN1, rather than just port 1/0/2.

I am not a Cisco expert, but I think it is a configuration issue on the 3750 as to why the data is not being transmitted.

Can anyone offer some suggestions or help to get me going?

Has anyone else encountered the issue where the NTA 4.4 installer stops with an a message stating it needs an internet connection (it's the offline installer, why the check?)  Any who, the server actually has a connection to the internet. This was after trying to install with the online installer that stated it couldn't upgrade the Netflow Storage Database, go get the offline one...  I am so confused.

Case # 00129320

Hi Everyone,

Is there anyone experience it by adjusting the the absolute time period the netflow conversation instead giving a different time?

This afternoon i noticed that my NTA Summary page's Sources resource just decided to show all of the interfaces on all of our Cisco devices and Riverbeds even if they weren't sending Netflow data.  It was only showing the 900 or so interfaces that were sending flows.  Any idea to hide the interfaces that aren't configured for Netflow?

We just installed a Cisco ASR 1002, The old net flow commands used in our 3845 do not work. Has anyone set configuration to export Top-Talkers?

Thanks

I have a question, how can I upgrade NTA to version 4.2.2, what´s the procedure and which are the accounts that I must take into account before moving the database to a dedicated server.

Thanks for your help!

I know that many people probably are running into a similar problem that I just did.  We've got software on the network that we want to use as targets for NetFlow traffic.  Since most hardware (in our case Cisco) only can point to two different NetFlow targets, I had to try and find a way to handle move this information around without too much complexity.

WIth that in mind, I started my searching and stumbled across a few documents talking about a software package called "samplicate" or "samplicator."  I played with it for a bit and was astounded that it worked so simply.  It's also got a very small footprint on VMware's Hypervisor.

I decided to blog about it and also to create an OVA Hyper-V export file that anyone can import directly to the Hypervisor.  Take a look at it, and hit me back with any questions or comments.

After the software install and running for few days. We have power fail, after reboot, I cannot access the Orion Web console, erroe message pop up "there was no endpoint listening at net.tcp://cpputil:17777/orion/core/businesslayer". I check with all required service were up and running. (UTIL is the collerctor/server)

I have a question, how can I upgrade NTA to version 4.2.2, what´s the procedure and which are the accounts that I must take into account before moving the database to a dedicated server.
