3- It then update the SADMIN database with the latest system information files just collected.
This is the responsibility of the sadm_database_update.py script.

4- It is responsible to update the rrd database (Round Robin Database) that allow you to view the performance graph of your systems.
This is done by the sadm_nmon_rrd_update.sh script.

5- The next step is to scan the network subnet you selected to give you an exact picture of your IP usage and take a backup of your SADMIN database.
This step is done by the sadm_subnet-lookup.py script.

6- Finally, a backup of the SADMIN database is taken by the sadm_backupdb.sh script.

This script does a lot of things but actually all it does is to start the six scripts that will do each a different job. It has to run early in the morning, so when you wake up or arrive to work you have the latest information about your systems. You may change the execution time if you want in “/etc/cron.d/sadm_server” but it as to run early in the morning and after the “sadm_client_sunset.sh” script on the clients. The “sadm_client_sunset.sh” script is the one that generate the latest data that this script is collecting and processing.
