beorn7	9eafed0f79	promql: Add `histogram_count` and `histogram_sum` This follow a simple function-based approach to access the count and sum fields of a native Histogram. It might be more elegant to implement “accessors” via the dot operator, as considered in the brainstorming doc [1]. However, that would require the introduction of a whole new concept in PromQL. For the PoC, we should be fine with the function-based approch. Even the obvious inefficiencies (rate'ing a whole histogram twice when we only want to rate each the count and the sum once) could be optimized behind the scenes. Note that the function-based approach elegantly solves the problem of detecting counter resets in the sum of observations in the case of negative observations. (Since the whole native Histogram is rate'd, the counter reset is detected for the Histogram as a whole.) We will decide later if an “accessor” approach is really needed. It would change the example expression for average duration in functions.md from histogram_sum(rate(http_request_duration_seconds[10m])) / histogram_count(rate(http_request_duration_seconds[10m])) to rate(http_request_duration_seconds.sum[10m]) / rate(http_request_duration_seconds.count[10m]) [1]: https://docs.google.com/document/d/1ch6ru8GKg03N02jRjYriurt-CZqUVY09evPg6yKTA1s/edit Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
