How should you visualise metrics with timestamp value in Grafana?

[John Bryan Sazon]

Hi folks,

Given the following metrics for Go, I want to know in a Graph when a garbage collection happened, and how much CPU and latency it took.

go_memstats_last_gc_time_seconds – contains unix timestamp when last GC finished.

go_memstats_last_gc_cpu_fraction – shows the fraction of this program’s available CPU time used by GC since the program started.

A sample Grafana JSON model will be really appreciated.

Thanks!
