Open Stack

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 
Pragya jain
