output snapshot as json

[zachvalenta]

ask

CLI arg to output snapshot of system metrics (CPU, mem, disk, et al.) as JSON

why

Diffing. For example, let's say your machine feels laggy. You open gotop and things look pretty normal, but you don't remember the metrics from the last time you opened gotop, so unless something is very obviously wrong (machine is super hot, runaway process is hogging memory) you won't have any useful comparisons to make.

Whereas, with the JSON output option, you could just gotop --json > gotop-metrics-<date>.json to establish a baseline and then, when things get laggy, compare your current situation to the baseline.
