Firewall Analyzer System Requirements

This section lists the minimum system requirements for installing and working with EventLog Analyzer - Distributed and Standalone editions

  • Hardware Requirements

    The minimum hardware requirements for installing and working with Firewall Analyzer (Standalone and Distributed Editions) are given below.

    • 1GHz Pentium Dual Core processor or equivalent
    • 1 GB of RAM*
    • 1 GB of disk space*
    • Monitor that supports 1024x768 resolution

    *The following table recommends the disk space and RAM size requirements of the system where Firewall Analyzer is installed. The disk space and RAM size requirements depends on the number of devices sending log information to Firewall Analyzer, the number of firewall log records received per second or the firewall log data received per day by Firewall Analyzer.

    Recommended Minimum RAM Requirement

    Log Records RateRAM Size
    Up to 100 Logs/sec1 GB
    100 - 500 Logs/sec2 GB
    500 - 1000 Logs/sec4 GB
    Above 1000 Logs/sec4 GB (64 Bit)
    Above 1000 Logs/sec8 GB

    Hard Disk Space Requirement

    The split up is: Archive+Index+MySQL=Total

    1000 Logs/sec 920+480+2100=3.5 TB 1750+750+4200=6 TB 2850+1250+6400=10.5 TB

    CPU Requirements

    • Dedicated machine has to be allocated to process more than 200 logs per second.
    • Dual core processors are needed to process more than 500 logs per second.
    • Quadra core processors are needed to process more than 1000 logs second.

    RAM Requirements

    • Number of firewalls handled by the Firewall Analyzer will increase the requirement of the above RAM values. So it is better to have RAM value higher than the suggested value in case of having more than 5 firewalls.

    Separate Installation

    • Firewall Analyzer server and MySQL database can be installed in separate machines, in case of higher log rate with low-end CPU machines.

    Hard Disk Requirements for more months

    • The above Hard Disk space requirement projected is for one month. If you need to archive the logs for more number of months, multiply the above requirements with the number of months based on your requirement.

    Note:The Log Records Per Second is the total log records received per second by Firewall Analyzer from all the configured devices.

  • PostgreSQL Performance Improvement Parameters

    PostgreSQL Performance Improvement Parameters (for Firewall Analyzer version 7.5 Build 7500 onwards)

    For better performance, we recommend replacing the existing PostgreSQL parameters mentioned in postgres_ext.conf available under <Firewall Analyzer Home>\pgsql\data\ directory

    port = 33336This change requires Firewall Analyzer Appplication/Service restart
    shared_buffers = 128 MBMinimum requirement is 128 KB. This change requires Firewall Analyzer Appplication/Service restart
    work_mem = 12 MBMinimum requirement is 64 KB.
    maintenance_work_mem = 100 MBMinimum requirement is 1 MB.
    checkpoint_segments = 15Logfile segments minimum 1 and 16 MB each
    checkpoint_timeout = 11 minutesRange: 30 seconds to 1 hour
    checkpoint_completion_target = 0.9checkpoint target duration is 0.0 - 1.0
    seq_page_cost = 1.0This parameter is measured in an arbitrary scale
    random_page_cost = 2.0This parameter is measured in same scale as above
    effective_cache_size = 512MB
