Cache Volume¶
Each configured cache volume receives a complete set of statistics from
Traffic Server. They are differentiated from each other by the incrementing number that is
part of the statistic name. The volume number begins at 0 and
increments by 1 for each additional volume.
The statistics are documented in this section using the default volume number in
a configuration with only one cache volume: 0.
