Following are the software requirements for the IEPM-BW monitoring node.

• Recommended operating system is the latest stable version of RedHat or any flavour of Fedora, more suitably Fedora Core 5.
• Two accounts should be created on the monitoring machine as these are needed to install and run IEPM-BW.
  • 'iepm' is a user account and is used for running IEPM-BW.
    • Account = iepm, home directory = /home/iepm
  • Second account is an account with root privileges. This is account is used for installation and administration. It's 'cyrus' in my case.
    • Account = cyrus, home directory = /home/cyrus
      You can have your own account, but don't forget to replace it at every place with your own account.
• An apache web server has to be available, and the recommended document root is '/var/www'.
• Standard MySQL must be installed on the system. Most recommended is the latest stable release, as this will facilitate assuring the upward compatibility of the code.
• Make sure that the system is configured to autostart MySQL and httpd (apache web server) upon booting. On some systems this can be done with 'chkconfig'. Commands are

        chkconfig httpd on  
        chkconfig mysqld on 

• The following /etc/sysctl.conf parameters are recommended for optimum performance

  /proc/sys/net/core/wmem_max=20971520
  /proc/sys/net/core/rmem_max=20971520
  /proc/sys/net/core/rmem_default=65536
  /proc/sys/net/core/wmem_default=65536
  /proc/sys/net/ipv4/tcp_rmem=4096 87380 20971520
  /proc/sys/net/ipv4/tcp_wmem = 4096 65536 20971520

Keep in mind to open port for each and every other service you run. e.g. HTTP, NTP etc

• To allow for running OWAMP, the monitoring and target hosts should be configured with 4 NTP servers. The OWAMP documentation discusses how to setup NTP.
• The latest version of JAVA must be installed on the monitoring host.
• Gnuplot 4.0 is required and must be installed on the monitoring host machine
• Perl should be installed locally on the machine. It can be either in /usr/bin/perl or /usr/local/bin/perl. There should be a link from where it doesn't exist to where it exists. Suppose if Perl path is /usr/bin/perl, its link should be created at /usr/loca/bin/perl. Perl modules must be installed on the system.
