bwplotka	3119567d5b	scrape: Add metadata for automatic metrics. Signed-off-by: bwplotka <bwplotka@gmail.com>	12 months ago
bwplotka	9385f31147	scrape: Fix metadata in WAL not working for histograms and summaries. The was a bug (due to confusion?) on the local metadata cache that is cached by metric family not the series metric name. The fix is to NOT use that local cache at all (it's still needed for current metadata API implementation, added TODO on how we can get rid of it). I went ahead and also rename Metric field in metadata structs to MetricFamily to make clear it's not always __name__. Signed-off-by: bwplotka <bwplotka@gmail.com>	12 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>	1 year 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>	1 year ago

Arthur Silva Sens	7aacef9b42	bugfix: Decouple native histogram ingestions and protobuf parsing Up until this point, if a scrape was done with the protobuf format Prometheus would always try to ingest native histograms even with the feature flag disabled. This causes problems with other feature-flags that depend on the protobuf format, like 'created-timestamp-zero-ingestion'. This commit decouples native histogram parsing from ingestion, making sure ingestion only happens when the 'native-histogram' feature-flag is enabled.
