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. Signed-off-by: Łukasz Mierzwa <l.mierzwa@gmail.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

beorn7	9e500345f3	textparse/scrape: Add option to scrape both classic and native histograms So far, if a target exposes a histogram with both classic and native buckets, a native-histogram enabled Prometheus would ignore the classic buckets. With the new scrape config option `scrape_classic_histograms` set, both buckets will be ingested, creating all the series of a classic histogram in parallel to the native histogram series. For example, a histogram `foo` would create a native histogram series `foo` and classic series called `foo_sum`, `foo_count`, and `foo_bucket`. This feature can be used in a migration strategy from classic to native histograms, where it is desired to have a transition period during which both native and classic histograms are present. Note that two bugs in classic histogram parsing were found and fixed as a byproduct of testing the new feature: 1. Series created from classic _gauge_ histograms didn't get the _sum/_count/_bucket prefix set. 2. Values of classic _float_ histograms weren't parsed properly.

Bryan Boreham	1ed94142fc	remote-write: slow down retries to avoid DDOS (#9634 ) * remote-write: slow down retries to avoid DDOS Increase the default max retry time from 100ms to 5 seconds. Remote write calls are retried after a recoverable error such as the back-end returning 500. Prometheus waits the minimum time and retries, then doubles the wait on each subsequent retry until the maximum is reached. If some data is still getting through, remote-write will also increase shards, and the default maximum is 200. 200 shards sending every 100ms is 20 calls per second, to a back-end that is already in trouble. 5 seconds was chosen to match the default BatchSendDeadline: if we can afford to wait that long for no response, then we can wait the same time to retry.

Damien Grisonnet	b50f9c1c84	Add label scrape limits (#8777 ) * scrape: add label limits per scrape Add three new limits to the scrape configuration to provide some mechanism to defend against unbound number of labels and excessive label lengths. If any of these limits are broken by a sample from a scrape, the whole scrape will fail. For all of these configuration options, a zero value means no limit. The `label_limit` configuration will provide a mechanism to bound the number of labels per-scrape of a certain sample to a user defined limit. This limit will be tested against the sample labels plus the discovery labels, but it will exclude the __name__ from the count since it is a mandatory Prometheus label to which applying constraints isn't meaningful. The `label_name_length_limit` and `label_value_length_limit` will prevent having labels of excessive lengths. These limits also skip the __name__ label for the same reasons as the `label_limit` option and will also make the scrape fail if any sample has a label name/value length that exceed the predefined limits. Signed-off-by: Damien Grisonnet <dgrisonn@redhat.com> * scrape: add metrics and alert to label limits Add three gauge, one for each label limit to easily access the limit set by a certain scrape target. Also add a counter to count the number of targets that exceeded the label limits and thus were dropped. This is useful for the `PrometheusLabelLimitHit` alert that will notify the users that scraping some targets failed because they had samples exceeding the label limits defined in the scrape configuration.
