+FREQ

The +FREQ parameter specifies which frequency column values to collect. This parameter is only used by BMC AMI Stats.

You can set +FREQ in the BMC AMI Utilities configuration to specify the default value for your installation. The BMC configured default value is MOST. You can override +FREQ by specifying FREQ in the SYSIN DD statement.
