The IEPM-BW system architecture is based on  MySQL database on each individual monitoring host, various daemons and servers, and a crontab.

There are three file 'systems' associated with IEPM-BW Monitoring systems: the source code, the report storage, and the IEPM database which is a MySQL data base. Each monitoring host has these. The target hosts only have the target system source code.

The IEPM data base is used for storage of the monitoring system's configuration and data storage. There are also two short configuration files which reside in /etc/. They are /etc/iepm.cnf which provides absolutely required information to the system, and /etc/my.cnf which is used by MySQL to define the IEPM data base.

The MySQL database contains all the configuration information for the probes that are to be made (node information, probe types, probe options, probe timing, etc.) and the specifications for the various analyses and graphs that are to be generated. It also contains tables where the probe data is stored and some tables to save the results of the various analyses.

IEPM-BW Daemons, Servers, and Cleanup Scripts

Since everything is started up by the crontab, when the system reboots it automatically restarts itself. You must make sure that 'http' and 'MySQL' daemons are autostarted by the operating system upon reboot.
