> It's weird that the bins are reset at every monitoring interval but min and max are tracked over the lifetime of the process. Makes it impossible to set alarms on max value as they'll never shut off unless the process is restarted. Histogram metrics should reset min and max at snapshot time too.
> For discussion.
