AppFlow Configuration on Citrix Netscaler Device

Enterprise Devices like Citrix Netscaler, Sonicwall are started supporting AppFlow export. What this AppFlow export really means? AppFlow:- AppFlow is a new flow export standard for finding data pertaining to applications & transactions in the network infrastructure. It gives greater visibility to Application traffic utilization and performance. AppFlow addresses the following requirements of Application Performance Management:
  • No need for Costly equipment for Application Optimization.
  • Cloud Compatible
  • Standard flow export
AppFlow Design:- The AppFlow exported from a device has 2 parts:
  • TCP based network Information
  • Application Layer data

Barracuda NG Firewall now supports IPFIX

Barracuda NG Firewall released their new firmware 5.2.3, curious to know whats new?? Visit the link to know the complete set of features: Here, in this blog we are discussing what is important for us, yes its IPFIX. Firmware release 5.2.3 introduces IPFIX streaming support. NetFlow Analyzer supports IPFIX flows in addition to NetFlow, sFlow, Appflow and many more flow formats.  These IPFIX packets can be send to NetFlow Analyzer server and start report generation for Barracuda Firewall. Please find below the screenshot of IPFIX configuration on Barracuda NG Firewall, we found this fr…

Application Performance Monitoring using NetFlow Analyzer

In most of the Corporate networks, the common problem seen over decades is that application performance worsens during business hours. Network Admin managing the corporate network faces the huge task of finding out what is causing the slowness in accessing the application hosted on a remote data center. The application performance can degrade due to following reasons:
  1. Application installed server is not good enough (Related Hardware).
  2. Bandwidth availability is less when accessing from remote office
The first point can be troubleshooted using our ManageEngine tools like ManageEngine OpManager and ManageEngine Application Manager. We will concentrate on the 2nd Point which is our focus area, since

AppFlow Support in NetFlow Analyzer

Flow based traffic analytics gives better visibility into network traffic compared to SNMP based traffic monitoring. The importance of flow based analysis is increasingly gaining prominence over traditional SNMP based traffic monitoring. As a result, we see a majority of routing & switching devices supporting flow analytics. Citrix has now joined this bandwagon by adding support for flow based traffic analytics on its Citrix Netscaler device. IPFIX is a major flow export which is now supported by various vendors. In addition to IPFIX, Citrix supports AppFlow. AppFlow:- AppFlow is a new flow export standard for finding data pertaining to applications & transactions in the network infrastru…

IPFIX support in Juniper Device

I’d rather say this is an IPFIX era, almost all the enterprise level routing and switching device vendors have started adopting IPFIX technology. Juniper device with its own standard jFlow is now supporting IPFIX on most of their major devices. This means that IPFIX is going to make a very big revolution in traffic monitoring technology in days to come. What is IPFIX? IPFIX is similar to NetFlow v9 export, of course NetFlow v9 is the base for IPFIX. IPFIX exports IP flow information from the routers and switch interfaces. The IPFIX protocol allows network administrators to  analyze their traffic patterns.

We have quite a lot of customers with Juniper devices in their netwo…

Configuring Maipu routers to export IPFIX

While working with one of our customers who had a Maipu Router, we realized that we don’t have the router’s NetFlow configuration in our website and I am sharing it with you in this blog.   Maipu Routers are capable of exporting “IP Flow Information Export” in short IPFIX. NetFlow Analyzer will be able to analyze IPFIX data and thus resulting in monitoring of Maipu Routers.  Give below are the configuration that has to be done for enabling IPFIX on the Maipu device. configuration: router[config]# ipfix source serial0/0 router[config]# ipfix destination 9996 router[config]# ipfix template refresh timers 1 router[config]# ipfix template refresh packets 5

nProbe and NetFlow Analyzer

What every Network Administrator expects from a bandwidth monitor while monitoring input and throughput on the device interface/port is: Who is using? Which Application is consuming my Bandwidth? Which Port and Protocol are used? The above information can be seen if you have NetFlow/jFlow/sFlow supported device and have configured it to export NetFlow packets to the server where you have installed NetFlow Analyzer. How can you monitor a network effectively using NetFlow even if the devices are not capable of exporting NetFlow Packets? Is it possible to do a detailed traffic analysis?. Consider a network has Layer 3 Switch like (Cisco 3750 or 2900 series) to which users are connected. The up-link port of s…

Accountability in an Enterprise!

Large enterprises which span across various countries face a challenge when it comes to monitoring bandwidth usage across various branches.  Harder still is the accountability, who is using what application or who is using a non-business-critical application which is clogging the bandwidth and suffocating a much needed business critical application. At times, depending on the department in an enterprise, the critical applications will vary. In such a case it is important for network managers to account department wise bandwidth usage. For enterprises dealing with client projects, it is critical to keep track of bandwidth used by the enterprise team, for chargeback, allocated for that projec…

NetFlow Analyzer tips on twitter!

We (@NetFlow_geek) will be tweeting t(w)ips on capabilities of NetFlow Analyzer which will help you get the most out of NetFlow, sFlow, jFlow, IPFIX, Netstream and more. NetFlow analyzer runs on both Linux and Windows, so no worries! Following these “twips” will help you understand the capability of NetFlow, sFlow and other flows in your network. These flows when analyzed by NetFlow Analyzer helps you gain in-depth visibility of your network traffic, various applications in your network and the bandwidth utilization. “We were struggling to get the exact details such as source, destination and the time on which certain applications were used. Once we had ManageEngine NetFlow Analyzer, w…
