This caused several metrics to alias, confusing the Prometheus server. Fix it by: * Renaming the "tcp_log_bucket" UMA zone to "tcp_log_id_bucket". Also, rename "tcp_log_node" to "tcp_log_id_node" for consistency. * Not exporting sysctls with "(LEGACY)" in the description. That is used by ZFS sysctls that have been replaced by others, many of which alias to the same Prometheus metric name (like "vfs.zfs.arc_max" and "vfs.zfs.arc.max").
