Owen Williams	6566c5a2b3	scrape: Add config option for escaping scheme request. (#16066 ) The new metric_name_escaping_scheme config option works in parallel with metric_name_validation_scheme and controls which escaping scheme is requested when scraping. When not specified, the scheme will request underscores if the validation scheme is set to legacy, and will request allow-utf-8 when the validation scheme is set to utf8. This setting allows users to allow utf8 names if they like, but explicitly request an escaping scheme rather than UTF-8.

Bryan Boreham	e86b9812f4	[BUGFIX] Scraping: bump cache iteration after error Backport of #16174 to LTS release-2.53 branch. We use the cache iteration number to detect when the same metric has occurred twice in a scrape. We need to bump this number at the end of every scrape, not just successful scrapes. The `iter` number is also used: * After a successful scrape, to delete older metrics and metadata. * To detect when metadata changed in this scrape. None of those additional cases is broken by incrementing the number on error. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	3 months ago

Bryan Boreham	7b03796d0f	Scraping: stop storing discovered labels (#15261 ) Instead of storing discovered labels on every target, recompute them if required. The `Target` struct now needs to hold some more data required to recompute them, such as ScrapeConfig. This moves the load from every Prometheus all of the time, to just when someone views Service Discovery in the UI. The way `PopulateLabels` is used changes; you are no longer expected to call it with a part-populated `labels.Builder`. The signature of `Target.Labels` changes to take a `labels.Builder` instead of a `ScratchBuilder`, for consistency with `DiscoveredLabels`. This will save a lot of work when many targets are filtered out in relabeling. Combine with `keep_dropped_targets` to avoid ever computing most labels for dropped targets.

TJ Hoplock	e0104a6b7e	ref: JSONFileLogger slog handler, add scrape.FailureLogger interface Improves upon #15434, better resolves #15433. This commit introduces a few changes to ensure safer handling of the JSONFileLogger: - the JSONFileLogger struct now implements the slog.Handler interface, so it can directly be used to create slog Loggers. This pattern more closely aligns with upstream slog usage (which is generally based around handlers), as well as making it clear that devs are creating a whole new logger when interacting with it (vs silently modifying internal configs like it did previously). - updates the `promql.QueryLogger` interface to be a union of the methods of both the `io.Closer` interface and the `slog.Handler` interface. This allows for plugging in/using slog-compatible loggers other than the JSONFileLogger, if desired (ie, for downstream projects). - introduces new `scrape.FailureLogger` interface; just like `promql.QueryLogger`, it is a union of `io.Closer` and `slog.Handler` interfaces. Similar logic applies to reasoning. - updates tests where needed; have the `FakeQueryLogger` from promql's engine_test implement the `slog.Handler`, improve JSONFileLogger test suite, etc. Signed-off-by: TJ Hoplock <t.hoplock@gmail.com>	7 months ago

TJ Hoplock	6ebfbd2d54	chore!: adopt log/slog, remove go-kit/log For: #14355 This commit updates Prometheus to adopt stdlib's log/slog package in favor of go-kit/log. As part of converting to use slog, several other related changes are required to get prometheus working, including: - removed unused logging util func `RateLimit()` - forward ported the util/logging/Deduper logging by implementing a small custom slog.Handler that does the deduping before chaining log calls to the underlying real slog.Logger - move some of the json file logging functionality to use prom/common package functionality - refactored some of the new json file logging for scraping - changes to promql.QueryLogger interface to swap out logging methods for relevant slog sugar wrappers - updated lots of tests that used/replicated custom logging functionality, attempting to keep the logical goal of the tests consistent after the transition - added a healthy amount of `if logger == nil { $makeLogger }` type conditional checks amongst various functions where none were provided -- old code that used the go-kit/log.Logger interface had several places where there were nil references when trying to use functions like `With()` to add keyvals on the new *slog.Logger type Signed-off-by: TJ Hoplock <t.hoplock@gmail.com>	9 months ago
