In a nutshell, the script uses two MySQL tables dbeacon_cacti.MN_ANNOUNCEMENT_CHANNEL and the table name constructed of the table prefix MN, the two character country code and the circuit name, in the example above, the second table would be dbeacon_cacti.MN_DE_DFN-Primary. The script executes an SNMPGet on the router using the specified OID, it compares the value of the counter received from the SNMPGet with the value stored in the dbeacon_cacti.MN_ANNOUNCEMENT_CHANNEL table for the specific circuit name. It uses these values to calculate the circuit utilisation, and stores this value in the circuit specific MySQL table. In addition, it replaces the value of the counter in the dbeacon_cacti.MN_ANNOUNCEMENT_CHANNEL with the new value obtained from the SNMPGet.
