<font face="sans-serif">yes, it is using statsD tool to aggregate metrics for you. But you can't get it for individual request. </font><br>

<tt><font><div><div class="h5">Hi,<br>
<br>
I am looking at the Swift codebase and stumbled upon something interesting.<br>
<br>
Several functions in the swift code base have a "@timing_stats()"<br>
annotation. Does this provide a way for profiling a swift cluster? Is<br>
it possible to get stats for individual get/put requests in Swift? If<br>
so, it'll be great if someone can point me to the documentation.<br>
<br>
Thanks in advance.<br>
-Shri<br>
