Table 4.8. Options
| Name | Description |
|---|
`-a, --all | Print statistics for all virtual machines and containers on the server. |
--loop
| Print statistics every second until the program is terminated. |
--filter <pattern>
| Specifies the subset of performance statistics to collect and print. If omitted, all available statistics is shown. Asterisks (*) can be used as wildcards for any number of arbitrary characters. The available filters are listed below (<N> is the device or filesystem index).
