What does downstream connection length show? #2

Open gr8Adakron opened 3 years ago

Hey @alexgervais what does downstream connection length specify - I guess its not latency as its going in thousands (ie: if converted to millisecond on y-axis it goes into minutes and hours )

Some explanation will be helpful

Hi @gr8Adakron ! The "downstream connection length" is the length of time the clients have an open connection to Ambassador. It can typically be a few seconds for browsers or minutes for gRPC clients. The connection length is different from the individual client request length, and idle timeouts can be configured: https://www.getambassador.io/docs/edge-stack/latest/topics/using/timeouts/#idle-timeout-idle_timeout_ms.

I hope this helps!
