Fabian Reinartz	8fa18d564a	storage: enhance Querier interface usage ... This extracts Querier as an instantiateable and closeable object rather than just defining extending methods of the storage interface. This improves composability and allows abstracting query transactions, which can be useful for transaction-level caches, consistent data views, and encapsulating teardown.	9 years ago
Julius Volz	f92532f254	api: Consolidate web API contexts ... This is based on the common/route changes in https://github.com/prometheus/common/pull/61.	9 years ago
Julius Volz	c187308366	storage: Contextify storage interfaces. ... This is based on https://github.com/prometheus/prometheus/pull/1997. This adds contexts to the relevant Storage methods and already passes PromQL's new per-query context into the storage's query methods. The immediate motivation supporting multi-tenancy in Frankenstein, but this could also be used by Prometheus's normal local storage to support cancellations and timeouts at some point.	9 years ago
Julius Volz	ed5a0f0abe	promql: Allow per-query contexts. ... For Weaveworks' Frankenstein, we need to support multitenancy. In Frankenstein, we initially solved this without modifying the promql package at all: we constructed a new promql.Engine for every query and injected a storage implementation into that engine which would be primed to only collect data for a given user. This is problematic to upstream, however. Prometheus assumes that there is only one engine: the query concurrency gate is part of the engine, and the engine contains one central cancellable context to shut down all queries. Also, creating a new engine for every query seems like overkill. Thus, we want to be able to pass per-query contexts into a single engine. This change gets rid of the promql.Engine's built-in base context and allows passing in a per-query context instead. Central cancellation of all queries is still possible by deriving all passed-in contexts from one central one, but this is now the responsibility of the caller. The central query context is now created in main() and passed into the relevant components (web handler / API, rule manager). In a next step, the per-query context would have to be passed to the storage implementation, so that the storage can implement multi-tenancy or other features based on the contextual information.	9 years ago
Anders Daljord Morken	e9885ecb94	Bugfix: Avoid divide-by-zero panic on query_range?step=0	10 years ago
Julius Volz	3bfec97d46	Make the storage interface higher-level. ... See discussion in https://groups.google.com/forum/#!topic/prometheus-developers/bkuGbVlvQ9g The main idea is that the user of a storage shouldn't have to deal with fingerprints anymore, and should not need to do an individual preload call for each metric. The storage interface needs to be made more high-level to not expose these details. This also makes it easier to reuse the same storage interface for remote storages later, as fewer roundtrips are required and the fingerprint concept doesn't work well across the network. NOTE: this deliberately gets rid of a small optimization in the old query Analyzer, where we dedupe instants and ranges for the same series. This should have a minor impact, as most queries do not have multiple selectors loading the same series (and at the same offset).	10 years ago
Fabian Reinartz	97f62c021e	api: drop legacy API	10 years ago
beorn7	da8cb10b43	Partition the status tab into items in a dropdown ... I got feedback from different sources about rules and targets being too heavy in the status tab if their are lots of them. This change also allows for more fine-granular locking.	10 years ago
Julius Volz	0c1e7a5b00	Support time range in /api/v1/series endpoint. ... This adds optional "start" and "end" form values that may be used to restrict the time range of returned series. Fixes https://github.com/prometheus/prometheus/issues/1542	10 years ago
Jonathan Boulle	38098f8c95	Add missing license headers ... Prometheus is Apache 2 licensed, and most source files have the appropriate copyright license header, but some were missing it without apparent reason. Correct that by adding it.	10 years ago
beorn7	4b574e8a61	Switch chunk encoding to type 2 where it was hardcoded type 1 before ... The chunk encoding was hardcoded there because it mostly doesn't matter what encoding is chosen in that test. Since type 1 is battle-hardened enough, I'm switching to type 2 here so that we can catch unexpected problems as a byproduct. My expectation is that the chunk encoding doesn't matter anyway, as said, but then "unexpected problems" contains the word "unexpected".	10 years ago
beorn7	836f1db04c	Improve MetricsForLabelMatchers ... WIP: This needs more tests. It now gets a from and through value, which it may opportunistically use to optimize the retrieval. With possible future range indices, this could be used in a very efficient way. This change merely applies some easy checks, which should nevertheless solve the use case of heavy rule evaluations on servers with a lot of series churn. Idea is the following: - Only archive series that are at least as old as the headChunkTimeout (which was already extremely unlikely to happen). - Then maintain a high watermark for the last archival, i.e. no archived series has a sample more recent than that watermark. - Any query that doesn't reach to a time before that watermark doesn't have to touch the archive index at all. (A production server at Soundcloud with the aforementioned series churn and heavy rule evaluations spends 50% of its CPU time in archive index lookups. Since rule evaluations usually only touch very recent values, most of those lookup should disappear with this change.) - Federation with a very broad label matcher will profit from this, too. As a byproduct, the un-needed MetricForFingerprint method was removed from the Storage interface.	10 years ago
beorn7	a7408bfb47	Unify duration parsing ... It's actually happening in several places (and for flags, we use the standard Go time.Duration...). This at least reduces all our home-grown parsing to one place (in model).	10 years ago

Fabian Reinartz	33aab4169c	Anchor regexes in vector matching ... This commit makes the regex behavior of vector matching consistent with configuration and label_replace() by anchoring it. Fixes #1200	10 years ago
Julius Volz	46c5260761	Support escape sequences in strings and add raw strings. ... This adapts some functionality from the Go standard library for string literal lexing and unquoting/unescaping. The following string types are now supported: Double- or single-quoted strings: These support all escape sequences that Go supports in double-quoted string literals. The difference is that Prometheus also has single-quoted strings (instead of single-quoted runes in Go). Raw newlines are not allowed. Backtick-quoted raw strings: Strings quoted in backticks are treated as raw strings just like in Go and may contain raw newlines and other special characters directly.
