NetFlow Analyzer support for nProbe extended metrics
Hi, I would like to know why NetFlow Analyzer cannot support ALL the extended metrics the nProbe can offer like DPI and response time. Benefit from nProbe: - not all the customers have access to the routers so they cannot export NetFlow from them - enabling NetFlow/sFlow/JFlow ... on a router or switch can overload the CPU - not all the network equipment support NetFlow - nProbe are cost effective and can be deployed widely in the network - can decode SSL traffic - DPI analysis: Facebook, not HTTP.
Alerts display
Hello, Is there a way I can display all alerts with options regarding date, interface,... etc For example, I have a profile for 90% link utilization. I want to see - all alerts for: a specific date a specific time frame specific interfaces ... At this moment we can just click on existing number of alerts and we'll have all the alerts displayed. There is also an option to have ONLY 100 events per page but nothing else. This will be helpful to see the amount of alerts in 24h for a specific interface.

Netflow for remote routers over IPSec VPN
Hi, I am trying to configure netflow collection for 2 remote routers to a local netflow analyser. My local router shows up without a problem. The 2 remote routers both say they are exporting udp packets to the correct server but they don't show up. I have set the export source to be the inside interface on the remote routers to ensure it is routed correctly through the vpn tunnel. Any ideas? Cheers, Mat.
NFA and MediaTrace on Cisco 3945E
I have followed the ManageEngine blog posts for configuring MediaTrace on a Cisco router and am unable to add an initiator to NFA after configuring the router. It acts as if it accepts the ID and password, does not actually ever add the initiator to the system. I'm wondering if this is due to the newer Cisco 3945E routers that we are running IOS 15.3.2T. Has anyone else got this to work? Also, is there support for HTTPS so that user ID and passwords aren't passed in clear text. If the local
NFA Pro Performance Tuning with PostgreSQL
Hi guys, you have a performance tuning topic here, which is describing how to tune the MySQL DB, which was used in previous NFA packages. Now NFA uses Postgres. Can you give any performance tuning tips for it? It would be very helpful, because We have troubles with performance (we have free RAM, but the /tmp folder collects lots of giant flow_log files).

Netflow Analyzer directory structure and backups
I just inherited a NetFlow Analyzer installation that is running out of space. The long term solution is more HD space, but in the short term, I would like to move some data to a different HD. I see recent data (data & mysql) existing in 2 locations: D:\NetFlow D:\AdventNet\ME\NetFlow\backups The D:\NetFlow data seems to be current, while the other data (D:\AdventNet...) is timed stamped as of 0120 this morning. I would like to move the AdventNet directory to a separate HD. Is this backup

When I try to see all alerts for last hour for example it would be nice to have a filter as option to see all alerts only for a specific Interface. Is this possible?

Moving the NFA DB to another drive
Hi, I'm evaluating NFA and want to move the DB (just the DB, not the app it self) from the C driv to another drive (windows). I can't find any documentation on how to do this.

Alert Profiles No attachment option
Hi all For some reason recently my Netflow analyzer alert profile has stopped e-mailing attachments. Basically what we have is alert profiles on each WAN interface that sends us an e-mail plus a pdf attachment when the WAN link is hitting 90% capacity, this enables us to be on the front foot, also the pdf gave us the information at a glance that we needed to see what was using the bandwidth. However now the alert profile I have had setup since day 1 is still sending us alerts but with no pdf attachment,

Traffic flow in Bytes
Any way to get the traffic flow per IP in bps vs bytes. For example; search for an IP on our network results in good data; however, for Traffic, the metric is in Bytes. Is there anyway to report how many bits per second an IP address is doing in a specific time slot? This option is currently available in nfdump. Additionally, how do your report bytes per packet, flows per second, etc. Basically, I was hoping to replace nfdump to an application that was a bit more intuitive for other users Thanks

NetFlow Analyser cannot get SNMP information
Hi. I'm testing NetFlow Analyser version 9.8.5 on a Windows 2008 server. The application is not able to recover SNMP informations from my Cisco routers with the snmp community I'm using. This snmp community has this character in it : & I think it might be the problem because if I use a community with letters and digits only there is no problem. This snmp community does not give me trouble in the OPManager Netflow Plugin. Thanks.
