[-PipelineVariable <String>] [-ZapiRetryCount <Int32>] [<CommonParameters>]
DESCRIPTION
Get a list of current counter values of instances of an object. This will return the values of all specified counters and instances of the specified object with one call.
PARAMETERS
-Name <String>
Name of the object to get counter values for.
-Instance <String[]>
List of instance names for which to get counter values. This element can be used to limit data collection to a specified subset of the instances of the object.
-Counter <String[]>
List of counters whose values will be retrieved. This element can be used to limit data collection to a specified subset of the counters of instances of the object. If this element is absent, values of all counters will be retrieved.
-PrivilegeLevel <String>
Name of the privilege level. Possible values: "basic", "admin", "advanced", "diag". If the element is absent, the default privilege of the object will be used.
-FilterData <String>
A string, representing filter-data, in the format of key=value supporting multiple key-value pairs via comma separation. The applied filter is a combination of ANDing the key-value pairs.
-SampleId <String>
Name of the sample.
This parameter is available with Data ONTAP 8.4 and up.
-Max <Int32>
Maximum number of instances.
This parameter is available with Data ONTAP 8.4 and up.
-SortKey <String>
Counter used for sorting instances.
This parameter is available with Data ONTAP 8.4 and up.
-SortOrder <String>
Sort order. Possible values are 'ascending' and 'descending'.
This parameter is available with Data ONTAP 8.4 and up.
-Controller <NcController[]>
A clustered Data ONTAP controller to receive this cmdlet, as embodied by an NcController object. This parameter is returned by the Connect-NcController cmdlet. If not specified, the value in the global variable CurrentNcController is used. In
the latter case, if CurrentNcController contains a collection of NcController objects, this cmdlet is invoked on each controller in succession.
-PipelineVariable <String>
-ZapiRetryCount <Int32>
The number of times to retry commands that return with errors that may succeed after a retry
-InstanceUuid <String[]>
List of instance UUIDs for which to get counter values. This element can be used to limit data collection to a specified subset of the instances of the object.
<CommonParameters>
This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer, PipelineVariable, and OutVariable. For more information, see
about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).
