This INTEGER enumeration selects the length of each PM sample interval for the profile from a fixed menu of system-supported values (other, minutes1, minutes5, minutes10, and further minute options that continue past where the SYNTAX text was cut off), per its DESCRIPTION. Every other timing field in this profile -- the Adjustment/Alert interval and their evenly-divisible-by-sample-interval rule -- is defined relative to whatever is chosen here, so changing this value after the fact can retroactively make an existing Adjustment/Alert Interval configuration invalid if it no longer divides evenly. For example, selecting minutes5 means an Adjustment Interval of 20 minutes is valid (evenly divisible), but one left over from a previous minutes10 setting at 15 minutes would violate the divisibility rule and need to be reconfigured.
