+
+	a metric is a node in a tree reachable via a numeric id (OID, in SNMP way) or a simple string:
+
+	uwsgi.worker.1.requests
+	uwsgi.custom.foo.bar
+
+	the oid representation:
+
+		1.3.6.1.4.1.35156.17 = iso.org.dod.internet.private.enterprise.unbit.uwsgi
+		1.3.6.1.4.1.35156.17.3.1.1 = iso.org.dod.internet.private.enterprise.unbit.uwsgi.worker.1.requests
+		1.3.6.1.4.1.35156.17.3.1.1 = iso.org.dod.internet.private.enterprise.unbit.uwsgi.worker.1.requests
+		1.3.6.1.4.1.35156.17.3.1.2.1.1 = iso.org.dod.internet.private.enterprise.unbit.uwsgi.worker.1.core.1.requests
+		1.3.6.1.4.1.35156.17.4.1 = iso.org.dod.internet.private.enterprise.unbit.uwsgi.system.load_avg
+		...
+
+	each metric is a collected value with a specific frequency (a frequency of zero means the value is re-computed every time)
+	metrics are meant for numeric values signed 64 bit, but they can be exposed as:
+
+	gauge
+	counter
+	absolute
+
+	both 32 and 64bit, both signed and unsigned
+
+	metrics are managed by a dedicated thread (in the master) holding a linked list of all the items. For few metrics it is a good (read: simple) approach,
+	but you can cache lookups in a uWSGI cache for really big list.
+
+	struct uwsgi_metric *um = uwsgi_register_metric("worker.1.requests", "3.1.1", UWSGI_METRIC_COUNTER, UWSGI_METRIC_PTR, &uwsgi.workers[1].requests, 0, NULL);
+	prototype: struct uwsgi_metric *uwsgi_register_metric(char *name, char *oid, uint8_t value_type, uint8_t collect_way, void *ptr, uint32_t freq, void *custom);
+
+	value_type = UWSGI_METRIC_COUNTER/UWSGI_METRIC_GAUGE/UWSGI_METRIC_ABSOLUTE
+	collect_way = UWSGI_METRIC_PTR -> get from a pointer / UWSGI_METRIC_FUNC -> get from a func with the prototype int64_t func(struct uwsgi_metric *); / UWSGI_METRIC_FILE -> get the value from a file, ptr is the filename
+
+	when freq is zero the value is recomputed whenever requested, otherwise the metrics thread compute it every time the frequency is elapsed and caches it
+
+	For some metric (or all ?) you may want to hold a value even after a server reload. For such a reason you can specify a directory on wich the server (on startup/restart) will look for
+	a file named like the metric and will read the initial value from it. It may look an old-fashioned and quite inefficient way, but it is the most versatile for a sysadmin (allowing him/her
+	to even modify the values manually)
+
+	When registering a metric with the same name of an already registered one, the new one will overwrite the previous one. This allows plugins writer to override default behaviours
+
+	Applications are allowed to update metrics (but they cannot register new ones), with simple api funcs:
+
+	uwsgi.metric_set("worker.1.requests", N)
+	uwsgi.metric_inc("worker.1.requests", N=1)
+	uwsgi.metric_dec("worker.1.requests", N=1)
+	uwsgi.metric_mul("worker.1.requests", N=1)
+	uwsgi.metric_div("worker.1.requests", N=1)
+
+	and obviously they can get values:
+
+	uwsgi.metric_get("worker.1.requests", no_cache|force=False)
+	if the second parameter is True, the value is recomputed (but if it is a metric with a cache, the cache value will not be updated accordingly, this is the job of the metric thread)
+
+	Updating metrics from your app MUST BE ATOMIC, for such a reason a uWSGI rwlock is initialized on startup and used for each operation (simple reading from a metric does not require locking)
+
+	Metrics can be updated from the internal routing subsystem too:
+
+		route-if = equal:${REQUEST_URI};/foobar metricinc:foobar.test 2
+
+	and can be accessed as ${metric[foobar.test]}
+
+	The stats server exports the metrics list in the "metrics" attribute (obviously some info could be redundant)
