This read-write integer sets how often, in seconds, the agent samples the variable named in the corresponding cpqMeAlarmVariable entry, and it cannot be modified once the alarm's status is valid. Administrators tune this interval to balance responsiveness against overhead, being careful the underlying counter won't roll over between samples. For example, setting this to 30 for a fast-changing counter avoids missing a wraparound that a 300-second interval might mask.
