Database Tuning Parameters

When you find that the client response is slow and the reports are taking longer time to get generated, you can tune a few database parameters to improve the performance of the system. The database parameters for NetFlow Analyzer are tuned to work well with 512 MB of RAM and in cases where you are running with more RAM, you can easily tune the MySQL parameters to extract better performance. This can result in significant improvements in the client response. These parameters can be set in startDB.bat file present in <NetFlow Analyzer Home>/bin directory (startDB.sh in case of Linux).

The 2 main parameters are the key_buffer_size and the innodb_buffer_pool_size. These values are set to --key_buffer_size=180000000 --innodb_buffer_pool_size=212000000 by default

Note: Please take a back up of this file before you make any changes. In case you are uncomfortable making these changes, please send a mail to netflowanalyzer-support@manageengine.com so that we can assist you in doing this.

  • For a machine running with 1 GB of RAM, you can set these to
    --key_buffer_size=360000000 --innodb_buffer_pool_size=424000000
  • For a machine running with 2 GB of RAM, you can set these to
    --key_buffer_size=720000000 --innodb_buffer_pool_size=848000000
