What metrics to export? #304

Open anacrolix opened 5 years ago

anacrolix commented 5 years ago

This issue will serve to discuss and collect specific metrics for export, through Prometheus, or Prometheus-compatible tooling (to keep us focused on the kinds of values), such as in #297. It is not a 1:1 list, but rather a list of things we want to and can observe. Units, and types can be figured out in implementation to avoid getting off-topic here.

Here is the list:

Number of k-buckets
Number of entries in each k-bucket
Outbound/inbound message sizes
Outbound/inbound message counts
Outbound request latency
Write latency (time between wanting to send a message, and sending it #285 and #92)

@raulk I'd like some suggestions on aspects of the dial queue to be exported.
