The -filtervalue parameter filters a view that is based on specific attribute values that relate to each object type. You can combine multiple filters to create specific searches, for example, -filtervalue name=fred:status=online. The help (-filtervalue) specifies the attributes that are available for each object type.
Capacity values displayed in units other than bytes might be rounded. When filtering on capacity, use a unit of bytes, -unit b, for exact filtering.
You can use the asterisk (*) character as a wildcard character when names are used. The asterisk character can be used either at the beginning or the end of a text string, but not both. Only one asterisk character can be used in a -filtervalue parameter.
