+	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)
