Describes the balloon device statistics.

This structure represents the return value requested by GET /balloon/statistics, which describes detailed information of the balloon device.

Fields

target_pages: u64

Target number of pages the device aims to hold. Required: true

actual_pages: u64

Actual number of pages the device is holding. Required: true

target_mib: u64

Target amount of memory (in MiB) the device aims to hold. Required: true

actual_mib: u64

Actual amount of memory (in MiB) the device is holding. Required: true

swap_in: Option<u64>

The amount of memory that has been swapped in (in bytes).

swap_out: Option<u64>

The amount of memory that has been swapped out to disk (in bytes).

major_faults: Option<u64>

The number of major page faults that have occurred.

minor_faults: Option<u64>

The number of minor page faults that have occurred.

free_memory: Option<u64>

The amount of memory not being used for any purpose (in bytes).

total_memory: Option<u64>

The total amount of memory available (in bytes).

available_memory: Option<u64>

An estimate of how much memory is available (in bytes) for starting new applications without pushing the system to swap;

disk_caches: Option<u64>

The amount of memory, in bytes, that can be quickly reclaimed without additional I/O. Typically these pages are used for caching files from disk.

hugetlb_allocations: Option<u64>

The number of successful hugetlb page allocations in the guest.

hugetlb_failures: Option<u64>

The number of failed hugetlb page allocations in the guest.
