    • With its Universal Log Parsing and Indexing (ULPI) technology, EventLog Analyzer can support any log and data source that are in human-readable format.
    • For analyzing logs from Windows NT machine, WMI core should have been installed in Windows NT machine
    • Syslog’s received from SNARE agents for Windows will be displayed as Windows hosts


    RAM Size and Disk Space Requirement Approximation

    The following table recommends the RAM size and disk space requirements of the machine in which the EventLog Analyzer is installed. The RAM size and disk space requirements depends on the number of host sending log information to EventLog Analyzer, the number of log records received per second or the log data received per day by EventLog Analyzer. The calculation is worked out for 100 hosts and an average log record size of 350 bytes.

    Log Records Rate or Volume

    RAM Size

    Hard Disk Space Requirement Per Month to Archive Logs

    100/sec or 3 GB/day

    1 GB

    300 GB

    500/sec or 14 GB/day

    2 GB

    1440 GB

    1000/sec or 28 GB/day

    4 GB

    2880 GB

    Supported Databases

    Bundled with the product

    • PostgreSQL

    External Databases

    • MS SQL 2000
    • MS SQL 2005
    • MS SQL 2008
    • MS SQL 2012


    PostgreSQL Performance Improvement Parameters (for EventLog Analyzer version 8.0 Build 8010 onwards)

    For better performance, we recommend replacing the existing PostgreSQL parameters mentioned in postgres_ext.txt available under <EventLog Analyzer Home>pgsqldata directory

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



    MySQL Performance Improvement Parameters (for EventLog Analyzer version 8.0 Build 8000 or earlier)

    For better performance, you can replace the existing MySQL parameters mentioned in startDB.bat/sh, available under <EventLog Analyzer Home>bin directory, with the following MySQL parameter changes corresponding to the EventLog Analyzer servers RAM Size.

    Hardware RAM Size

    MySQL Parameter Changes

    1 GB

    Default configuration as given in startDB.bat/sh

    2 GB

    " --innodb_buffer_pool_size=1200M "

    3 GB

    " --innodb_buffer_pool_size=1500M "

    4 GB

    " --innodb_buffer_pool_size=1500M "


    Recommended System Setup

    Apart from the System Requirements, the following setup would ensure optimal EventLog Analyzer performance.

    • Run EventLog Analyzer on a separate, dedicated PC or server. The software is resource-intensive, and a busy processor may cause problems to collect event logs
    • Use the MySQL bundled with EventLog Analyzer that runs on port 33335. You need not start another separate instance of MySQL
    • As mentioned in the pre-requisites, for better performance, you can modify the existing MySQL parameters
