    34  // List **Lists the metric values for a resource**.
    35  // Parameters:
    36  // resourceURI - the identifier of the resource.
    37  // timespan - the timespan of the query. It is a string with the following format
    38  // 'startDateTime_ISO/endDateTime_ISO'.
    39  // interval - the interval (i.e. timegrain) of the query.
    40  // metricnames - the names of the metrics (comma separated) to retrieve. Special case: If a metricname itself
    41  // has a comma in it then use %2 to indicate it. Eg: 'Metric,Name1' should be **'Metric%2Name1'**
    42  // aggregation - the list of aggregation types (comma separated) to retrieve.
    43  // top - the maximum number of records to retrieve.
    44  // Valid only if $filter is specified.
    45  // Defaults to 10.
    46  // orderby - the aggregation to use for sorting results and the direction of the sort.
    47  // Only one order can be specified.
    48  // Examples: sum asc.
    49  // filter - the **$filter** is used to reduce the set of metric data returned. Example: Metric contains
    50  // metadata A, B and C. - Return all time series of C where A = a1 and B = b1 or b2 **$filter=A eq 'a1' and B
    51  // eq 'b1' or B eq 'b2' and C eq '*'** - Invalid variant: **$filter=A eq 'a1' and B eq 'b1' and C eq '*' or B =
    52  // 'b2'** This is invalid because the logical or operator cannot separate two different metadata names. -
    53  // Return all time series where A = a1, B = b1 and C = c1: **$filter=A eq 'a1' and B eq 'b1' and C eq 'c1'** -
    54  // Return all time series where A = a1 **$filter=A eq 'a1' and B eq '*' and C eq '*'**. Special case: When
    55  // dimension name or dimension value uses round brackets. Eg: When dimension name is **dim (test) 1** Instead
    56  // of using $filter= "dim (test) 1 eq '*' " use **$filter= "dim %2528test%2529 1 eq '*' "** When dimension name
    57  // is **dim (test) 3** and dimension value is **dim3 (test) val** Instead of using $filter= "dim (test) 3 eq
    58  // 'dim3 (test) val' " use **$filter= "dim %2528test%2529 3 eq 'dim3 %2528test%2529 val' "**
    59  // resultType - reduces the set of data collected. The syntax allowed depends on the operation. See the
    60  // operation's description for details.
