ManageEngine NetFlow Analyzer is a web-based bandwidth monitoring tool that performs in-depth traffic analysis using data exported from NetFlow / Netstream /. NetFlow Analyzer has various editions to make the solution the best-fit for your needs. Available for small-medium businesses & large enterprises. Try now! DBEAVER CREATE NEW LOCAL DATABASE

There are 2 ways of backup :. Please use the command "sh UpdateManager. Why can't I add a router to NetFlow Analyzer? NetFlow Analyzer does not choose which routers or interfaces to monitor. Devices are auto-discovered. All you need to do is set up your interfaces to send NetFlow data to the specified port on NetFlow Analyzer. My router has been set up to export NetFlow data, but I still don't see it on the Dashboard.

There are a number of things you can check here:. For configuring SNMP, follow the steps below 1. Logon on to the router. Enter into the global configuration mode 3. Type the command snmp-server community public RO to set public as Read-Only community 4. Press ctrl and Z 5. Type the command write mem Back.

The graphs are empty. Graphs will be empty if there is no data available. If you have just installed NetFlow Analyzer, wait for at least ten minutes to start seeing graphs. If you still see an empty graph, it means no data has been received by NetFlow Analyzer. Check your router settings in that case. As far as aggregated data is concerned, NetFlow Analyzer maintains the top 'n' flows for every ten minutes slot.

The record count determines this 'n' values. By default it is set to You may set your own criteria for this purpose. Apart from this NetFlow Analyzer allows you to store raw data all flows -not just the top n for upto one month. Aggregated data is stored in 5 levels of tables - 10 Min, Hourly, 6 Hour, 24 Hour and Weekly tables and reports for different periods need to access the corresponding table. For example, very recent reports need to access the 10 Min table and old reports need to access the Weekly table.

You can access the table MetaTable to determine the table which contains data for the required time period. Raw data is stored in dynamically created tables and data pertaining to different devices routers reside in different table for different periods of time. You can access the table RawMetaTable to determine the table which contains data for the required report. If you need to change this globally, enter the new values in the same fields under Settings.

NetFlow Analyzer aggregates older data in less granular format and due to this reason some of the spikes may not show in older reports. While reports pertaining to last day is generated from tables with 10 minute granularity, reports pertaining to last week is generated from tables with 1 hour granularity For example, data in 10 minute table pertaining to , , , , and would all be aggregated and moved into hourly data tables for one data point pertaining to While the total data volumes is correct, the traffic rates will be averaged over this period.

This is the reason for the reduction in the reporting of bandwidth usage over time. Several factors can impact NBAR performance in software-based execution. Router Configuration 1. Number of protocols being matched against it 2. Number of regular expressions being used 3. The complexity of packet inspection logic required B. Traffic Profile Packet Protocol Sequence 1.

The number of flows 2. Long duration flows are less expensive than shorter duration flows 3. Stateful protocol matches are more performance impacting than static port applications. A single flow can be categorized as a single application only. In case of a conflict, applications with an exact match for the port number will be accounted for. You can change the time-out value to a higher value than the default 30 minutes by increasing the parameter session-timeout.

Change the value 30 to your desired time-range - say, You will have to restart NFA server for this to take effect. Please ensure that NFA is running. It creates a "Info. This contains DB related information. Please send us the "info. Configuring multiple NetFlow Listener ports can significantly enhance the flow handling rates.

You can configure upto 5 listener ports, each seperated by a comma. Please run your logziputil. This will create a zip file under the support folder please send us the zip file. Send us the. Also send your Machine configuration.

NetFlow Analyzer can be migrated to a new server with older data and configurations with certain conditions. Given below are the steps to migrate the installation and database to a different server. From Windows to Linux and vice versa 1. Shutdown the NetFlow Analyzer service.

These two folders contain all the collected data and configurations of NetFlow Analyzer. Then shutdown the NetFlow Analyzer service. Additionally, if you do not have a copy of the product license, please copy the AdventnetLicense. Once the migration is complete, you can apply the license from License Management page under Admin Operations in the product UI. Please check out the comparison document. Based on the hardware configuration of the system, a collector can handle around interfaces.

Refer sizing guide for hardware configuration. Central Server can handle any number of collectors. New collectors can be added seamlessly at anytime. Collector communicates through the https port of Central Server. SNMP parameters like read community, port can be configured while installing the collector. If you want to change after installing the collector, you can do so from a collector web client.

Collector will hold the data and sends them once connection is re-established. Thus collector ensures reliable data transfer. Collector contacts Central Server for two purposes. The frequency to send NetFlow data is 10 minutes and the frequency to get the configuration is one minute. Collector sends the data through secure https connection. We have bundled SSL certificates generated using Java's keytool. If you like to change the certificates, you can use the sslgen. You can view the actual bandwidth used for data transfer from the "Collector Details" page in the Central Server's web client.

You can find the link to this page under Admin Operations. The Collector Dashboard view shows the top 10 interfaces in each collector by default. To customize it, please use the "Customize" link beside the Dashboard link. If the collector is behind a proxy, then enter the proxy settings either in Collector's Installation screen or in the Settings page in web client. The licensing is based on the flow rate.

What is NetFlow? What are the different versions of NetFlow available? Is Cisco the only vendor supporting NetFlow? How many users can access NetFlow Analyzer simultaneously? Extensive graphs and intuitive reports make this information easy to analyze, and also help accelerate the troubleshooting process.

NetFlow Analyzer comes pre-loaded with a set of features that provide in-depth bandwidth usage statistics and let you drill down to see more details about a bandwidth traffic, application, or conversation etc. NetFlow Analyzer also includes other administrative options that help in managing enterprise networks and bandwidth utilization with ease.

Regardless of different types of flows, now you can view a complete picture of the usage, network performance, and traffic statistics of various network devices in single console. View the status of your links, and generate reports from just a web browser that is built on a JavaScript framework powered by Ember. This new Fluidic web client offers 10x more productivity and performance compared to the previous UI. The new user interfaces also features keyboard navigation across interface snapshot pages, alarms and performance graphs which helps network admins to access the information they are looking for even more quickly and easily.

View instant graphs for bandwidth utilization and traffic per link up to previous minute. Generate daily, weekly, monthly, and custom time period bandwidth reports showing peak traffic patterns from the day 1. Reconfigure application QoS with ACL to filter application traffic, thus reserve bandwidth for mission critical activities. Prioritize your network traffic accordingly. Now, NetFlow Analyzer can scale up to K flows per second without raw data storage and with raw data storage it can process upto k flow per second.

Helps you accurately measure your bandwidth growth over a period of time and helps to anticipate the changes in bandwidth with capacity planning reports. You can also generate on-demand billing for accounting and departmental chargebacks.

View bandwidth reports based on top applications, top hosts, and top conversations, DSCP, multicast. View bandwidth reports per Device and interfaces, showing top applications, top talkers in a single report.
