14.5.10. Retrieving Memory Statistics for a Running Domain
This command may return varied results depending on the hypervisor you are using.
The
dommemstat [domain] [--period (sec)][[--config][--live]|[--current]]
displays the memory statistics for a running domain. Using the --period
option requires a time period in seconds. Setting this option to a value larger than 0 will allow the balloon driver to return additional statistics which will be displayed by subsequent domemstat
commands. Setting the --period
option to 0, will stop the balloon driver collection but does not clear the statistics in the balloon driver. You cannot use the --live
, --config
, or --current
options without also setting the --period
option in order to also set the collection period for the balloon driver. If the --live
option is specified, only the running guest's collection period is affected. If the --config
option is used, it will affect the next boot of a persistent guest. If --current
option is used, it will affect the current guest state
Both the
--live
and --config
options may be used but --current
is exclusive. If no option is specified, the behavior will be different depending on the guest's state.
