    - * 

    
-     * "carsMeter": {

-     * "meanRate;colour=red" : 0,

-     * "meanRate;colour=blue" : 0,
-     * "oneMinRate;colour=blue" : 0,
-     * "fiveMinRate;colour=blue" : 0,
-     * "fifteenMinRate;colour=blue" : 0
-     * }
-     *
    - *

    - * The metadata output (as opposed to the data output) must collect tag - * information from actual instances of the metric under the overall metadata - * object. This example reflects two instances of the {@code barVal} gauge - * which have tags of "store" and "component." - *

    + * This builder is tuned to the needs of reporting metrics metadata. Metrics + * which share the same name but have different tags and have multiple + * values (called samples) need to appear in the data output as one + * object with the common name. The name of each sample in the output is + * decorated with the tags for the sample's parent metric. For example: + *

    + * 

    
+     * "carsMeter": {
+     * "count;colour=red" : 0,
+     * "meanRate;colour=red" : 0,
+     * "oneMinRate;colour=red" : 0,
+     * "fiveMinRate;colour=red" : 0,
+     * "fifteenMinRate;colour=red" : 0,
+     * "count;colour=blue" : 0,
+     * "meanRate;colour=blue" : 0,
+     * "oneMinRate;colour=blue" : 0,
+     * "fiveMinRate;colour=blue" : 0,
+     * "fifteenMinRate;colour=blue" : 0
+     * }
+     *
    + *

    + * The metadata output (as opposed to the data output) must collect tag + * information from actual instances of the metric under the overall metadata + * object. This example reflects two instances of the {@code barVal} gauge + * which have tags of "store" and "component." + * 

    
+     * "barVal": {
+     * "unit": "megabytes",
+     * "type": "gauge",
+     * "tags": [
+     *   [
+     *     "store=webshop",
+     *     "component=backend"
+     *   ],
+     *   [
+     *     "store=webshop",
