Bryan Boreham	cc7dcf5afe	[DOCS] Querying basics: explain range and instant queries I often see people ask questions that indicate they don't understand this point, and launching into "instant vector" and "range vector" is likely to point them in the wrong direction. Remove the admonishment that the reader mustn't confuse these things. Remove mention of "inferred sample timestamps" that is never explained.

zenador	ccfe14d7e7	PromQL: ignore small errors for bucketQuantile (#13153 ) promql: Improve histogram_quantile calculation for classic buckets Tiny differences between classic buckets are most likely caused by floating point precision issues. With this commit, relative changes below a certain threshold are ignored. This makes the result of histogram_quantile more meaningful, and also avoids triggering the _input to histogram_quantile needed to be fixed for monotonicity_ annotations in unactionable cases. This commit also adds explanation of the new adjustment and of the monotonicity annotation to the documentation of `histogram_quantile`. --------- Signed-off-by: Jeanette Tan <jeanette.tan@grafana.com>	1 year ago

Bryan Boreham	1e3fef6ab0	scraping: limit detail on dropped targets, to save memory (#12647 ) It's possible (quite common on Kubernetes) to have a service discovery return thousands of targets then drop most of them in relabel rules. The main place this data is used is to display in the web UI, where you don't want thousands of lines of display. The new limit is `keep_dropped_targets`, which defaults to 0 for backwards-compatibility. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	1 year ago
