get_host_senders on VDNT-Docker02 ran past 120 s: a prefix LIKE on plugin_metrics.resource_name can't use its index (the column's collation isn't C), so each read went through the whole table, and the host page's Who's sending panel repeats it on every refresh. The containers and NFS mounts under a host are now named from plugin_metric_latest, and their series read by resource IN (...) on the series index.
