The metrics in this metric category check for the following:
The largest chunk-free space in the tablespace. If any table, index, cluster, or rollback segment within the tablespace cannot allocate one additional extent, then an alert is generated.
Whether any of the segments in the tablespace are approaching their maximum extents. If, for any segment, the maximum number of extents minus the number of existing extents is less than 2, an alert is generated.
Only the tablespaces with problem segments are returned as results.
