System Requirements for NetFlow Analyzer

    The recommended hardware requirements for installing and running NetFlow Analyzer Essential & Enterprise Edition are as follows: 

    Parameter Essential Edition Enterprise Edition
    Central Server Collector
    Processor 2.4 GHz Quad Core Processor 2.4 GHz Dual Core 3.2 GHz Quad core
    RAM 4 GB 4 GB 8 GB
    Hard-disk space 200GB for database 600 GB 1 TB SATA hard disk
    Operating System 64 bit 64 bit 64 bit

     

    Please note that change in flow rate will lead to change in system requirements as below: 

    Rate of Flow/Second Processor RAM Disk space for Aggregate Data (Forever) Additional Disk space for RawData (Optional) Server Type

    0 to 3000

    2.4 GHz Quad Core Processor 4 GB 200 GB 75 GB/Day -

    3000 to 6000

    3.2 GHz Quad Core Processor 6 GB 200 GB 150GB/Day 64 bit

    6000 to 9000

    3.2 GHz Quad Core Processor 8 GB 200 GB 225GB/Day 64 bit

    100k (With Raw Data)

    2 x 3.2 GHz Quad Core Processor 48 GB+ 350 GB 1.5TB/Day 64 bit

    * HighPerf addon is recommended if the number of flows is >10k.
    * Aggregated data is calculated based on the top 100 records.

     

    For the device exporting NetFlow, ensure that the NetFlow export version format is exactly the same as the Cisco NetFlow version 5 or version 7 or version 9 format. For information on Cisco devices and IOS versions supporting Netflow, consult the Cisco NetFlow Device Support table.

    Port Requirements

    Port Name Default Port Numbers Usage

    Web server port 

    80 This is the port on which you will connect to the NetFlow Analyzer server from a web browser. You can change this at any time from the Settings tab.

     NetFlow Listener port 

    9996 This is the listener port on which NetFlow exports are received from routers. You can change this at any time from the Settings tab.

     Embedded database port 

    13306 This is the default port used to connect to the PGSQL database in NetFlow Analyzer.

     MSSQL 

    1433 This is the port that connects NetFlow Analyzer to a SQL database.

     SNMP 

    161 This is the default SNMP port to fetch the device information and configure SNMP based NBAR.

     HighPerf Database Port 

    27839 This is the default  HighPerf database port that connects NetFlow Analyzer to HighPerf (Actian Vector) database.

     HTTPS Port 

    443 This is the port through which the collector communicates with the central server.

    Database Requirements

    The following table lists the basic requirements for your OpManager database server.

    PostgreSQL

    • Comes bundled with the product.
    • In case of failover, please use MS SQL.

    Microsoft SQL

    1. Supported versions:

    SQL 2016 | SQL 2014 | SQL 2012 | SQL 2008

    2. Important Notices:

    1. For production use 64 bit versions of SQL
    2. Recovery mode should be set to SIMPLE.
    3. SQL and OpManager should be in the same LAN. Currently WAN based SQL installations are not supported.

    3. Collation:

    • English with collation setting (SQL_Latin1_General_CP1_CI_AS)
    • Norwegian with collation setting (Danish_Norwegian_CI_AS)
    • Simplified Chinese with collation setting (Chinese_PRC_CI_AS)

    • Japanese with collation setting (Japanese_CI_AS)
    • German with collation setting (German_PhoneBook_CI_AS)

    4. Authentication:

    Mixed mode (MSSQL and Windows Authentication).

    5. BCP:

    The "bcp.exe" and "bcp.rll" must be available in the bin directory.

    The BCP utility provided with Microsoft SQL Server is a command line utility that allows you to import and export large amounts of data in and out of SQL server databases quickly. The bcp.exe and bcp.rll will be available in the MSSQL installation directory. If MSSQL is in a remote machine, copy bcp.exe and bcp.rll files and paste them in the <\OpManager\bin> directory.

    The SQL server version compliant with the SQL Native Client must be installed in the same Server.

    Recommendations

    Memory(RAM):

    For Production environment, Highperf should be allocated with minimum of 10GB Memory & minimum of 16 cores (8 physical and 8 virtual).

    Hard Drive Configuration

    RAID10 / RAID5 / RAID6 hard drive with faster spinning disks at 15k RPM or higher is recommended. SSDs are recommended for maximum performance.

    File System

    On Windows, NTFS would give maximum performance.
    On Linux you could use ext2, ext3, ext4 or xfs.
