Brian Brazil	220e78b9c3	Consider a series stale after 4.1 intervals with no data. ... To cover the cases where stale markers may not be available, we need to infer the interval and mark series stale based on that. As we're lacking stale markers this is less accurate, however it should be good enough for these cases. We need 4 intervals as if say we had data at t=0 and t=10, coming via federation. The next data point should be at t=20 however it could take up to t=30 for it actually to be ingested, t=40 for it to be scraped via federation and t=50 for it to be ingested. We then add 10% on to that for slack, as we do elsewhere.	9 years ago

Brian Brazil	80b40e6d91	Add initial staleness handing to promql. ... For instant vectors, if "stale" is the newest sample ignore the timeseries. For range vectors, filter out "stale" samples. Make it possible to inject "stale" samples in promql tests.	9 years ago
Brian Brazil	fcc88f0e1e	query/query_range should return eval timestamp ... Query and query_range should return the timestamp at which an evaluation is performed, not the timestamp of the data. This is as that's what query range asked for, and we need to keep query consistent with that. Query for a matrix remains unchanged, returning the literal matrix.	9 years ago
Brian Brazil	517b81f927	Add timestamp() function. ... Make the timestamp of instant vectors be the timestamp of the sample rather than the evaluation. We were not using this anywhere, so this is safe. Add a function to return the timestamp of samples in an instant vector. Fixes #1557	9 years ago

beorn7	07f1bdfe94	Fix MOD binop for scalars and vectors ... Previously, a floating point number that would round down to 0 would cause a "division by zero" panic.	9 years ago
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	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
beorn7	71571a8ec4	promql: Fix (and simplify) populating iterators ... This was only relevant so far for the benchmark suite as it would recycle Expr for repetitions. However, the append is unnecessary as each node is only inspected once when populating iterators, and population must always start from scratch. This also introduces error checking during benchmarks and fixes the so far undetected test errors during benchmarking. Also, remove a style nit (two golint warnings less…).	9 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
Brian Brazil	0303ccc6a7	Add quantile aggregator.	10 years ago
Brian Brazil	16690736ab	Add count_values() aggregator. ... This is useful for counting how many instances of a job are running a particular version/build. Fixes #622	10 years ago
Brian Brazil	3e5136e36d	Make topk/bottomk aggregators.	10 years ago
Brian Brazil	3b89616d82	Allow on, ignoring, by and without wit empty laberls. ... This offers new semantics in allowing on() for matching two single-element vectors with no known common labels. Previosuly this was often done using on(dummy). This also allows making it explict that you meant to do an aggregation without labels via by(). Fixes #1597.	10 years ago
Brian Brazil	246a817300	Flip vector matching to be ignoring by default. ... This is a noop semantically.	10 years ago
