Measures reported by NutClusSharesTest
Shares (SMB) and exports (NFS) encapsulate file directories. There are two types of shares or exports:
The client network enables communication between the clients and the FSVMs, allowing clients to access the Files shares. Self-service restore capability is set up in Nutanix Files at the file server level to restore files in case if the files in the file share or file server are corrupted or are exposed to malicious attacks. Individual file shares can be excluded from self-service giving the administrator control of which shares leverage this protection and which don't. If a file share is not enabled with self-service restore, then files from the file share may be lost forever in case the file is corrupted or lost due to malicious attacks. Similarly, if the file shares are running out of space, users may not be able to store their files. For an administrator, it is essential to keep track on the file shares that are included in the file servers on a daily basis and ensure that the file shares have adequate space for user operations. The Nutanix File Shares test helps administrators in this regard!
This test auto-discovers the file shares on the file servers and reports the type of each file share. Using this test, administrators can easily isolate those file shares on which self-service restore and Access Based Enumeration capabilities are not enabled. Administrators are also alerted to those file shares that are running out of space.
Outputs of the test: One set of results for each Nutanix file server:file share on the target the Nutanix Acropolis Prism Element being monitored.
Descriptor: Nutanix File Server:File Share
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Share_type |
Indicates the type of this file share. |
|
The detailed diagnosis of this measure lists the name of each file server VM, IP address, vCPUs and size of the memory allocated to each file server VM.
The values that this measure can take and its corresponding numeric values correspond to the states are as follows:
| Measure Value |
Numeric Value |
| HOMES |
1 |
| GENERAL |
2 |
| Others |
3 |
Note:
By default, the test reports the Measure Values listed in the table above to indicate the type of the file share. In the graph of this measure however, the state is indicated using the corresponding numeric equivalents mentioned in the table above.
|
| Prev_verson |
Indicates whether/not self-service restore (SSR) is enabled on this file share. |
|
Self-service restore is set up in Nutanix Files at the file server level. Individual file shares can be excluded from self-service giving the administrator control of which shares leverage this protection and which don't. Self-service restore leverages snapshots for recovery with frequency settings as often as once per hour.
The restore process uses Windows previous version, a feature of Windows that is already available to your end users in their Windows explorer file properties area.
An end user who is looking to restore a previous version of a file can right click a folder and bring up the properties window. The Previous Version tab will access the available snapshots on Nutanix Files to give the end user a list of the files available. Users can drill down to find the right file from the right period of time and restore that file in-place or as a new version. This capability is supported across both SMB and NFS shares without changing the user experience.
The values that this measure can take and its corresponding numeric values are as follows:
| Measure Value |
Numeric Value |
| Yes |
1 |
| No |
0 |
Note:
By default, the test reports the Measure Values listed in the table above to indicatewhether/not self-service resotre is enabled on the file share. In the graph of this measure however, the Measure Values are indicated using the corresponding numeric equivalents only i.e., 0 or 1.
|
| Acess_base |
Indicates whether/not Access Based Enumeration is enabled on this file share. |
|
Access Based Enumeration(ABE) is a Microsoft Windows (SMB protocol) feature that filters the list of available files and folders on the file server to only include files and folders that the requesting user has read-access to. The filtering ensures that Files enforces read-and-write privileges for all users and that information can remain confidential. ABE controls the user visibility of shared folders on mounted file system shares based on the user permissions.
The values that this measure can take and its corresponding numeric values are as follows:
| Measure Value |
Numeric Value |
| Yes |
1 |
| No |
0 |
Note:
By default, the test reports the Measure Values listed in the table above to indicatewhether/not self-service resotre is enabled on the file share. In the graph of this measure however, the Measure Values are indicated using the corresponding numeric equivalents only i.e., 0 or 1.
|

|
| Max_size |
