> SS7 Link Schema Statistics
> The SS7 Link schema provides the following types of statistics:

> • | 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 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. All statistics are considered standards-based unless otherwise noted.
