Have you referred to this document?

Answers below based on that circa-April-2013 document, might need updates.

yes, swift-informant sits in the proxy server's pipeline and after each
request to the proxy server, sends three metrics to a
StatsD
 server

   -

   A counter increment for a metric like obj.GET.200 or cont.PUT.404.
   -

   Timing data for a metric like acct.GET.200 or obj.GET.200. [The README
   says the metrics will look likeduration.acct.GET.200, but I don't see
   the "duration" in the code. I'm not sure what Etsy's server does, but our
   StatsD server turns timing metrics into 5 derivative metrics with new
   segments appended, so it probably works as coded. The first metric above
   would turn into acct.GET.200.lower, acct.GET.200.upper, acct.GET.200.mean
   ,acct.GET.200.upper_90, and acct.GET.200.count]
   -

   A counter increase by the bytes transferred for a metric like
   tfer.obj.PUT.201.

statsdlog can track events from all Object Storage daemons, not just
proxy-server

[Openstack] query about Statsd

[pragya jain]

hello all,

I have some questions about Statsd server for openstack swift

Q1:  Is swift-informant middleware necessary to be included in 
proxy-server.conf in order to provide metrics to StatsD server?

Q2: what type of metrics does swift-informant middleware provide to StatsD 
server?

Q3:  What is StatsDlog? Is it a middleware or a daemon or something other? And, 
What type of metrics does it provide to StatsD server?

I had searched many documents, but I still have confusion about it.
Please somebody answer my questions.

Thanks
