The Stats tab stacked one large card per chart, so a VM with a few devices made a long page, and its "Real Time" and "Logs" sub-tabs were shown to every user although only a superuser may read the logs. The owner chose the layout from rendered options: a state line, CPU and memory side by side, one chart per NIC and disk below, each with its latest reading next to its title, and a small Graphs/Logs switch for superusers. Codex reviewed the tab; this is fixed: - Memory is shown in MiB (it was labelled MB), and its axis grows to the RSS when the RSS passes the balloon size instead of clipping it. - The CPU reading says it is of the host's CPUs. - A NIC is titled by its MAC, not an invented "eth0", and its readings are matched to its chart by the MAC: they were matched by position, so removing a NIC while the page was open moved the next one's readings into its chart. - A VM that is not running says nothing is measured. - The logs load whenever the Logs view is shown, by keyboard too; an empty answer says "None" and a failed one says so, instead of an empty table. The tab shows the latest 50 rows, with a link to all of the VM's rows on the Logs page. - The VM's header shows memory in MiB; it said MB.
