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.
