VsanAttachVsanSupportBundleToSr(attachVsanSupportBundleToSr)

Collect vSAN and vCenter support bundle and upload to VMware for the given SR (Service Request). The collected support bundles including vSAN health and tracing log bundle, all of ESXi host support bundle and VC support bundle The upload process will be in three stages separately with the order of bundle size to avoid possible time out, which are vCenter bundles, small high importance ESXi/vSAN manifests, vSAN traces and lower priority ESXi manifests. The network proxy for uploading is also supported by calling SetVsanClusterTelemetryConfig() in advance.

VsanQueryVcClusterHealthSummary(queryClusterHealthSummary)

Perform a cluster wide health check across all types of health checks. It's the primary API for fetching vSAN health status. This API runs a wide variety of health checks in many different categories against the cluster and returns both API-friendly and UI-friendly data. The 'fields' parameter should be used to return what the client is really interested in to limit the big result size for performance consideration. The API can either perform a health check against the up-to-date state of the hosts in the cluster and takes several seconds to return or it can retrieve the latest cached result to return in second. It's encouraged to fetch the cached data to get the quick response unless an update is required. Note: when this API is called directly from an ESXi host, following test groups are not supported: groupId = com.vmware.vsan.health.test.hcl

includeObjUuids*xsd:boolean

Whether to include detailed per-object health in the result.

Since vSphere API 5.5
fields*xsd:string[]

If set, only the properties listed in the array are returned in the result data object. Normally the output of this API can be quite large so this allows clients which are only interested in a subset to save network bandwidth and deserialization effort. The possible value is the field from the VsanClusterHealthSummary class like 'objectHealth', 'networkHealth' etc If unset, following properities are included in the result. 'clusterStatus', 'timestamp', 'clusterVersions', 'objectHealth', 'vmHealth', 'networkHealth', 'limitHealth', 'advCfgSync', 'createVmHealth', 'physicalDisksHealth', 'hclInfo', 'groups', 'overallHealth', 'overallHealthDescription', 'clomdLiveness', 'diskBalance'

Since vSphere API 5.5
fetchFromCache*xsd:boolean

True to return the result from cache directly instead of running the full health check. The cache will be updated and keep the latest vSAN health summary check result either triggering from user on-demand request or the periodical vSAN health check for triggering health event/alarm. Default is False.

Since vSphere API 5.5

VsanQueryVcClusterNetworkPerfTest(queryClusterNetworkPerfTest)

The test does so by picking one host as the sender, and having all other hosts be receivers. By virtue of being multicast traffic, any packet that the senders sends should be delivered to all receivers. If the network bandwidth below 20MB/s is too slow, and between 20MB/s and 50MB/s is low but OK, and anything above 50MB/s is within what VMware would expect.
