This reports the raw Coding Violation (BIP-8) count for one specific completed 15-minute bucket in the path's rolling 24-hour history. Because CVs are counted per error rather than per second, a technician can use a spike in one interval's CV count to gauge how dense the underlying bit-error rate was during that quarter-hour, rather than just knowing that errors happened. An interval showing 30 CVs but only 2 errored seconds indicates the errors that did occur were tightly clustered within just those 2 seconds rather than spread evenly across the 900-second window.
