----------------------------------
Summary: Add stat to track total number of network connections
Key: TS-3411
URL: https://issues.apache.org/jira/browse/TS-3411
Project: Traffic Server
Issue Type: Bug
Components: Network, Performance
Reporter: Susan Hinrichs
Currently, we can use proxy.process.http.total_client_connections or
proxy.process.http.total_incoming_connections to determine the number of TCP
connections that have been made from the user_agent to ATS, assuming that
HTTP/1.0 or HTTP/1.1 are used.
If SPDY or HTTP/2 are used, these counters will be incremented for each stream
not for each network connection.
It would be useful to add counters in the iocore/net area to directly track the
number of TCP connections that have been open over time. Right now only the
number of currently_open connections are tracked via
proxy.process.net.connections_currently_open.
I propose adding two new metrics proxy.process.net.connections_successful_in
and proxy.process.net.connections_successful_out
