Re : Netflow Alerts Profiles

Hi Karthik

I have this explame

If I set 90%, 3 time, 10 minutes it will send and email alert if the trafic exceds at 9:00, 9:01 and 9:02 and the next check It will do it at 9:12

If I set 90%, 3 time, 10 minutes it will send and email if the trafic exceds at 9:00, 9:04 and 9:07 and the next check It will do it at 9:17

The second escenario is possible? or it just counts if the exceds are continous? if one is less than 90% it will start again the counter?

Thank you

Hi ,

Thank you for writing to us. With respect to you example :

If you create an Utilization threshold 90%, 3 time, 10 minutes, if the utilization exceds at 9:00, 9:01 and 9:02 you will get an email alert at 09:02 and the there will be no check from 09:02 till 09:10.

The next threshold check will start from 09:10 to 09:20.

In NetFlow Analyzer we generate alert based on the Raw Data collected in the application. Please select the Retain Raw Data to 2 hours under Admin -> Raw Data Settings and check on the issue.

Hi ,

Thank you for writing to us. Please send us the screenshot of the issue that you are facing with the unclassified application named that you are able to see the Application tab, we will check and get back to you.

Regarding the reporting on the Http url report, you have to configure the device to export the Http url statistics. Please configuration another mace record and monitor as mentioned below and check on the issue:

flow record type mace HTTP_REC
collect application http uri statistics
collect application http host
collect interface input
collect interface output

flow monitor type mace HTTP_MON
exporter LaptopExp
record HTTP_REC
cache timeout update 1

policy-map type mace mace_global
class http-traffic
  flow monitor HTTP_MON

Once configured, all the mace enable command to the interface and check if you get the Http Url statistics.

Thanks & Regards,

Thanks Aravind. When I try to config as you suggested, I got an error:

CR3900-1(config-pmap-c)#flow monitor HTTP_MON
MACE: Unable to create the layout for client instance MACE-EXP-3 - Field unsupported
Warning: Exporter LaptopExp could not be activated because of the following unsupported fields:
    application http uri statistics
    application http host

% Setting exporter LaptopExp with flow record HTTP_REC failed

Is this because I have an old version of IOS?

Install of Netflow on windows 2012 server

I have been trying to install both the 32bit and 64bit of opmanager plugin for netflow.  We want to trial it and possibly purchase.

We have a central/probe design, I"m trying to install it on one of the probes.  After install there are no errors but it is just not listening on the ports.  I have changed the port to 8888 and all sorts of different ones with no luck.

Is there a trick to getting this plugin to install on 2012 server?  Should I be using the 32bit or 64bit.  I assume 64bit since my OS is but just confirming.

I changed the port for the webserver to 8888 because default would not work.

Hi,

Thank you for writing to us. You will have to install the same build as of Opmanager. If the opmanager is 64bit, you will need 64bit Netflow analyzer plug-in, irrespective of the OS build.
Login to Opmanager OLD UI>>Support>>Support and check if it is 32 or 64 bit installation.

Once done, Stop the Opmanager service and uninstall Netflow analyzer plug-in and remove the %opmanager%\Netflow folder.
Install the appropriate build of Netflow Analyzer plug-in from -
https://www.manageengine.com/network-monitoring/download.html

Start the Opmanager service and Netflow analyzer will start along. Wait for 5mins and try to login and update us.

So that seems to have done the trick to get it installed.  But now, i click netflow and its just hanging.  I'm going to try and reboot everything.

 I'll have to see why this probe is running 32bit.  I guess it was during install because there is no option to change during patch right?

Hi,

Thanks for the update. You may try from a different browser and the first startup will take a little longer.
You will have to migrate the installation from 32 to 64bit, it can't be done with patches.

Thank you for contacting us. Please restart the server and check on the status of the issue. It seems that the process is still running in the background. Restarting the server could resolve the issue.

Hi,

Thank you for writing to us. You can generate Capacity Planning Report only based on Interfaces and IPgroups in NetFlow Analyzer and any time period you need.

Also, Capacity Planning Report is an add-on for NetFlow Analyzer, make sure you have this feature purchased for your License only the you can generate the Capacity Planning Report.

Hi,

Thank you for writing to us. NetFlow Analyzer system requirement is only based on the flows received in the NetFlow Analyzer server and we do not have the option to predict the Flow rate on the server based on the Interfaces you are going to monitor in NetFlow Analyzer.

Please install NetFlow Analyzer on an server with the basic system requirement and mentioned in the below link and configure all your device that you want to monitor to send Flow packets to NetFlow Analyzer server, which will give you an fair idea regarding the flow rate on the server:

Re : Unable to get download details by LAN IP

Hi ,

Thank you for writing to us. NetFlow Analyzer will show only the information exported by the Device to the NetFlow Analyzer server by the device. It seems that you and set an NAT or Proxy from WAN to LAN and that is the reason you can only the Static IP address where the Download traffic is routed over the LAN.

To overcome this, you can monitor an Internal core switch ( Flow Exported Supported ) from where all the LAN traffic is routed and get the information on the Internal LAN traffic details.

Hi ManageEngine Team,

After the doing the process to resolved all SSID, and also the call support done to remotely visualize the real issue, we can still see traffics from 1SSID but not on the other SSIDs.

Please help on resolving this issue as we are really having problems and wanted to determine our wireless traffics.

Thanks,
