Add analyze histograms command to promtool (#12331)
Add `query analyze` command to promtool

This command analyzes the buckets of classic and native histograms,
based on data queried from the Prometheus query API, i.e. it
doesn't require direct access to the TSDB files.

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`.

Łukasz Mierzwa 870627fbed Add enable_compression scrape config option
Currently Prometheus will always request gzip compression from the target when sending scrape requests.
HTTP compression does reduce the amount of bytes sent over the wire and so is often desirable.
The downside of compression is that it requires extra resources - cpu & memory.

This also affects the resource usage on the target since it has to compress the response
before sending it to Prometheus.

This change adds a new option to the scrape job configuration block: enable_compression.
The default is true so it remains the same as current Prometheus behaviour.

Setting this option to false allows users to disable compression between Prometheus
and the scraped target, which will require more bandwidth but it lowers the resource
usage of both Prometheus and the target.

Fixes #12319.

George Krajcsovits e399395b01
Native histograms vs labels (#13005)
* Document le and quantile label transition due to native histograms

Fixes: #12984

For full explanation see the related issue. The le and quantile labels
are formatted as float with trailing .0 for whole number values when
native histograms is enabled, e.g. 10.0. This changes the resulting series
in Prometheus if previously we scraped the whole number itself, e.g. 10
over the text format.

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.
