I am trying to display TPS in Prometheus data source where I have metrics for total messages.
I am using rate function to basically achieve value2-value1/time2-time1.
- I can not go below 2m in the range for rate. Any reason?
- I can not use $__interval or $__rate_interval. If I use graph goes blank. Why this can not be used?
- I can only use $__range as duration for rate. Why this is usable?
- Please explain $__interval, $__rate_interval and $__range in layman terms as I feel I am missing something.
