Metrics related to HTTP and transport connections

[sandpwr]

Looks like with the current version, there is no way to see what is the current open connections on port 9200 and 9300. These metrics are very important when analysing issues specially with the sudden increase in load or number of connections.

Is it possible to include these metrics? or I'm missing these metrics somewhere in the list.

Thanks in advance!

Hello! What status of this feature? Is there some way to get something like http_total_open metric?

The http_total_open metrics would be a great addition for us.
