gary rong	be9172a7ac	rpc: metrics for JSON-RPC method calls (#20847) ... This adds a couple of metrics for tracking the timing and frequency of method calls: - rpc/requests gauge counts all requests - rpc/success gauge counts requests which return err == nil - rpc/failure gauge counts requests which return err != nil - rpc/duration/all timer tracks timing of all requests - rpc/duration/<method>/<success/failure> tracks per-method timing	2020-04-03 12:36:44 +02:00
