Host Vsan Health System Vsan Host Query Check Limits
Determines limit health, i.e.
if any system resources (free disk space, vSAN component counts, etc.) are exhausted, or would be exhausted after simulated failures. All information is as seen by this host, which under network partitions is not the global view.
Required privileges: System.Read
The unique identifier for the managed object to which the method attaches; the serialized managed object reference for a request has the form moType/moId, in this case HostVsanHealthSystem/{moId}.
The vSphere release schema. The current specification covers vSphere 9.0.0.0 APIs.

Summarized limit health as seen by this host
"VsanLimitHealthResult Object"The host name
Whether any issue found in the vSAN limit health check.
The maximum number of supported vSAN components in the host.
The number of remaining vSAN components can be created in the host.
It equals to the maximum supported components minus the used components.
The host component usage health status.
The status will be red if the used components exceeds 90% of total component number, the status will be yellow if it exceeds 75% of total components and it will be green if it's less than 75% of total component.
The lowest free disk space percentage among all of disks in the host.
This value will be 100 if there is no disk found in the host.
The total used disk space in byte, which is the larger value between reserved capacity and the data physically written into the disk.
The total vSAN capacity in byte.
It's the total of physical space which can be used for writing data including any of user data, metadata and the overhead data.
The disk free space health status.
The status will be red if the used disk space is larger than 90% of total space, the status will be yellow if it's larger than 70% of total space and it will be green if it's less than 70% of total space.
The reserved read cache size in byte.
The total read cache size in byte.
The read cache reservation health status.
The status will be red if the reserved read cache space is larger than 90% of total space, the status will be yellow if it's larger than 80% of total space and it will be green if it's less than 80% of total space.
The total logical capacity in byte.
The logical capacity used in byte.
The dedupMetadataSize used in byte.
The disk transient used in byte.
The disk group transient used in byte.
The space required by the vSAN internal operations like policy reconfiguration and we expect user to reserve this in cluster.
The space threshold to pause vSAN data resync operation, e.g., the reserved space for storage policy related object reconfigurations.
vSAN space efficiency metadata size in byte.
The space required for host rebuild if one of the host is down
The space required by the vSAN internal operations like policy reconfiguration at cluster level.
The additional space reserved by the vSAN internal operation at cluster level when vSAN operation capacity is enforced.
The total reserved capacity size in byte for all the capacity disks on a host.
