#6718 "A swarm container's metrics, normal and anomalies are keyed by its task name, so they start over whenever the task moves". Live, the move took VDNT-Docker02's I/O pressure (psi_io_full_avg60) from about 1% to about 23%, and passes of 5000 raw samples outran their 15 s slot. Each moved sample rewrites its row and every index on it. Batches are 1000 samples, and after a pass the task waits four times as long as it took, so it holds the disk for about a fifth of the time and the move slows if the disk does.
