Description: The number of seconds to wait between trigger samples. To encourage consistency in sampling, the interval is measured from the beginning of one check to the beginning of the next and the timer is restarted immediately when it expires, not when the check completes.

If the next sample begins before the previous one completed the system may either attempt to make the check or treat this as an error condition with the error 'sampleOverrun'.

A frequency of 0 indicates instantaneous recognition of the condition. This is not possible in many cases, but may be supported in cases where it makes sense and the system is able to do so. This feature allows the MIB to be used in implementations where such interrupt-driven behavior is possible and is not likely to be supported for all MIB objects even then since such sampling generally has to be tightly integrated into low-level code.

Systems that can support this SHOULD document those cases where it can be used. In cases where it can not, setting this object to 0 should be disallowed.
