Description: The number of discrete sampling intervals over which data shall be saved in the part of ahcfSampleTable associated with this ahcfConfigEntry.

If the ahcfConfigObjectType is 'columnar' and the SNMP probe detects at runtime that a new instance is available in the table (e.g. a new logical storage media is added to hrStorageTable),then the probe creates a new entry in the ahcfInstanceTable and uses the ahcfConfigDefaultBucketsReq as the value of ahcfInstanceBucketsRequested for this new entry.

The user can then modify the ahcfInstanceBucketsRequested if required to a value more specific to the new entry created (the new logical storage media added to hrStorageTable).

When the associated ahcfInstanceBucketsRequested object is created, the probe SHOULD set this object as closely to the requested value as is possible for the particular probe implementation and available resources.

There will be times when the actual number of buckets associated with this entry is less than the value of this object. In this case, at the end of each sampling interval, a new bucket will be added to the ahcfSampleTable.

When the number of buckets reaches the value of this object and a new bucket is to be added to the ahcfSampleTable, the oldest bucket associated with this ahcfConfigEntry shall be deleted by the agent so that the new bucket can be added.
