GoRelic-跟踪指标说明

I have added a trace in a Go function using the GoRelic as mentioned here. The numbers reported in GoRelic Dashboard for this trace are as follows:- (Please check the screen shot of the trace in NewRelic dashboard here)

Trace/ Prudsys Select/ max Average ms

Avg - 9.38k ms
Total - 37.5k ms
Max - 13.9k ms
Min - 5.48k ms
StdDev - 3.93k
Rate - 20.8 ms/sec
Count - 4 Samples

Can some one explain me:-

  1. What does k ms mean in 9.38k ms? Does it mean 9 sec 38ms?

  2. What does Rate - 20.8 ms/sec mean?

  3. What does max Average ms mean in "Trace/Prudsys Select/ max Average ms"?

  4. What does count - 4 Samples mean?
