Measure execution latency of a certain request method.
In order to measure latency for GET requests of a request handler you simply have to add the latency() decorator to the declaration:
@s.latency @s.async def get(self, *args, **kwargs): ...
The latency is recorded along the request path, i.e. if the request handler is defined like this:
the latency of GET/POST/PUT etc methods are stored with the path. In order to access the stats you may call /_system/stats/test/this or /_system/stats/test, e.g.
Meter the execution of certain requests.
The metered() stats will measure the 1/5/15 minutes averages for requests. This is also applied trivially:
@s.metered @s.async def get(self, *args, **kwargs): ...
