> NAT Realm Schema Statistics
> The NAT Realm schema provides the following types of statistics:
> Important: The NAT Realm schema is only available in StarOS 8.3 and later.

> • | Counter: A counter records incremental data cumulatively and rolls over when the counter limit is reached. The limit depends upon the counter data type.

> • | Gauge: A gauge statistic indicates a single value representative of a single instance. This type is often used to track particular events in time.

> Important: The format string syntax is described by Schema Format String Syntax in the Bulk Statistics Overview chapter.
> Important: Unless otherwise indicated, all statistics are counters. For statistics with the Int32 data type, the roll-over to zero limit is 4,294,967,295. For statistics with the Int64 data type, the roll-over to zero limit is 18,446,744,073,709,551,615. All counter statistics are cumulative, unless otherwise noted, and reset only by one of the following methods: roll-over (as described above), after a system restart, or after a clear command is performed.

> nat-rlm-port-chunk-average-usage-others | The average Others (ICMP or GRE) port usage in the allocated others ports, i.e out of allocated ‘Others’ ports how many got used. This is not a percentage value. This is a snapshot statistic. | Int32
> nat-rlm-max-port-chunk-subs | Total number of subscribers who have used maximum number of port chunks. This is a cumulative statistic. | Int64
> nat-rlm-max-port-chunk-used | The maximum number of port chunks used. This is a cumulative statistic. | Int32
> nat-rlm-max-cur-port-chunk-subs | Total number of current subscribers using maximum number of port chunks. This is a snapshot statistic. | Int64
> nat-rlm-max-cur-port-chunk-used | Total number of active subscribers using maximum number of port chunks. This is a snapshot statistic. | Int32
> Important: See Bulk Statistics Overview for statistics that are common to all schema.
