Usage Guidelines
This command enables enhanced history for the IP SLAs operation.
Performance statistics are stored in buckets that separate the accumulated data. Each bucket consists of
data accumulated over the specified time interval. When the interval expires, history statistics are
gathered in a new bucket. When the specified number of buckets is reached, statistic gathering for the
operation ends.
By default, IP SLAs maintain two hours of aggregated statistics for each operation. The value from each
operation cycle is aggregated with the previously available data within a given hour. The enhanced
history feature in IP SLAs allows for the aggregation interval to be shorter than one hour.
This command does not require a license.
Examples This example shows how to enable enhanced history gathering for a Cisco NX-OS IP Service Level
Agreements (SLAs) operation:

Number of seconds (sec) that the enhanced history should be gathered in
each bucket. When this time expires, enhanced history statistics are
gathered in a new bucket. The range is from 1 to 3600 seconds.

Number of buckets that should be retained in the system memory. When
this number is reached, statistic gathering for the operation ends. The
