+
+Metrics Library
+===============
+
+The Metrics library implements a mechanism by which *producers* can
+publish numeric information for later querying by *consumers*. In
+practice producers will typically be other libraries or primary
+processes, whereas consumers will typically be applications.
+
+Metrics themselves are statistics that are not generated by PMDs. Metric
+information is populated using a push model, where producers update the
+values contained within the metric library by calling an update function
+on the relevant metrics. Consumers receive metric information by querying
+the central metric data, which is held in shared memory.
+
+For each metric, a separate value is maintained for each port id, and
+when publishing metric values the producers need to specify which port is
+being updated. In addition there is a special id ``RTE_METRICS_GLOBAL``
+that is intended for global statistics that are not associated with any
+individual device. Since the metrics library is self-contained, the only
+restriction on port numbers is that they are less than ``RTE_MAX_ETHPORTS``
+- there is no requirement for the ports to actually exist.
+
+Initialising the library
+------------------------
+
+Before the library can be used, it has to be initialized by calling
+``rte_metrics_init()`` which sets up the metric store in shared memory.
+This is where producers will publish metric information to, and where
+consumers will query it from.
+
+.. code-block:: c
+
+    rte_metrics_init(rte_socket_id());
+
+This function **must** be called from a primary process, but otherwise
+producers and consumers can be in either primary or secondary processes.
+
+Registering metrics
+-------------------
+
+Metrics must first be *registered*, which is the way producers declare
+the names of the metrics they will be publishing. Registration can either
+be done individually, or a set of metrics can be registered as a group.
+Individual registration is done using ``rte_metrics_reg_name()``:
+
+.. code-block:: c
+
+    id_1 = rte_metrics_reg_name("mean_bits_in");
+    id_2 = rte_metrics_reg_name("mean_bits_out");
+    id_3 = rte_metrics_reg_name("peak_bits_in");
+    id_4 = rte_metrics_reg_name("peak_bits_out");
+
+or alternatively, a set of metrics can be registered together using
+``rte_metrics_reg_names()``:
+
+.. code-block:: c
+
+    const char * const names[] = {
+        "mean_bits_in", "mean_bits_out",
+        "peak_bits_in", "peak_bits_out",
+    };
+    id_set = rte_metrics_reg_names(&names[0], 4);
+
+If the return value is negative, it means registration failed. Otherwise
+the return value is the *key* for the metric, which is used when updating
+values. A table mapping together these key values and the metrics' names
+can be obtained using ``rte_metrics_get_names()``.
+
+Updating metric values
+----------------------
+
+Once registered, producers can update the metric for a given port using
+the ``rte_metrics_update_value()`` function. This uses the metric key
+that is returned when registering the metric, and can also be looked up
+using ``rte_metrics_get_names()``.
+
+.. code-block:: c
+
+    rte_metrics_update_value(port_id, id_1, values[0]);
+    rte_metrics_update_value(port_id, id_2, values[1]);
+    rte_metrics_update_value(port_id, id_3, values[2]);
+    rte_metrics_update_value(port_id, id_4, values[3]);
+
+if metrics were registered as a single set, they can either be updated
+individually using ``rte_metrics_update_value()``, or updated together
+using the ``rte_metrics_update_values()`` function:
+
+.. code-block:: c
+
+    rte_metrics_update_value(port_id, id_set, values[0]);
+    rte_metrics_update_value(port_id, id_set + 1, values[1]);
+    rte_metrics_update_value(port_id, id_set + 2, values[2]);
+    rte_metrics_update_value(port_id, id_set + 3, values[3]);
+
+    rte_metrics_update_values(port_id, id_set, values, 4);
+
+Note that ``rte_metrics_update_values()`` cannot be used to update
+metric values from *multiple* *sets*, as there is no guarantee two
+sets registered one after the other have contiguous id values.
+
+Querying metrics
+----------------
+
+Consumers can obtain metric values by querying the metrics library using
+the ``rte_metrics_get_values()`` function that return an array of
+``struct rte_metric_value``. Each entry within this array contains a metric
+value and its associated key. A key-name mapping can be obtained using the
+``rte_metrics_get_names()`` function that returns an array of
+``struct rte_metric_name`` that is indexed by the key. The following will
+print out all metrics for a given port:
+
+.. code-block:: c
+
+    void print_metrics() {
+        struct rte_metric_name *names;
+        int len;
+
+        len = rte_metrics_get_names(NULL, 0);
+        if (len < 0) {
+            printf("Cannot get metrics count\n");
+            return;
+        }
+        if (len == 0) {
+            printf("No metrics to display (none have been registered)\n");
+            return;
+        }
+        metrics = malloc(sizeof(struct rte_metric_value) * len);
+        names =  malloc(sizeof(struct rte_metric_name) * len);
+        if (metrics == NULL || names == NULL) {
+            printf("Cannot allocate memory\n");
+            free(metrics);
+            free(names);
+            return;
+        }
+        ret = rte_metrics_get_values(port_id, metrics, len);
+        if (ret < 0 || ret > len) {
+            printf("Cannot get metrics values\n");
+            free(metrics);
+            free(names);
+            return;
+        }
+        printf("Metrics for port %i:\n", port_id);
+        for (i = 0; i < len; i++)
+            printf("  %s: %"PRIu64"\n",
+                names[metrics[i].key].name, metrics[i].value);
+        free(metrics);
+        free(names);

+ * Metrics are statistics that are not generated by PMDs, and hence
+ * are better reported through a mechanism that is independent from
+ * the ethdev-based extended statistics. Providers will typically
+ * be other libraries and consumers will typically be applications.
+ *
+ * Metric information is populated using a push model, where producers
+ * update the values contained within the metric library by calling
+ * an update function on the relevant metrics. Consumers receive
+ * metric information by querying the central metric data, which is
+ * held in shared memory. Currently only bulk querying of metrics
+ * by consumers is supported.
