Brian Brazil	dcea3e4773	Don't append a 0 when alert is no longer pending/firing With staleness we no longer need this behaviour.	8 years ago
Brian Brazil	cc867dae60	Copy previous series and alert state more intelligently. Usually rules don't more around, and if they do it's likely that rules/alerts with the same name stay in the same order. If rules/alerts with the same name are added/removed this could cause a blip for one cycle, but this is unavoidable without requiring rule and alert names to be unique - which we don't want to do.	8 years ago
Brian Brazil	0451d6d31b	Add unittest for rule staleness, and rules generally.	8 years ago

Julius Volz	ac203ef0ee	Add externalURL template function (#2716 ) This allows users to e.g. add links back to the generating Prometheus right in their alert templates.	8 years ago

Jonathan Lange	2a2da40223	Make rule evaluation publicly available Means that a third-party can parse rules and run them with their own execution model.	8 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.	8 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.	8 years ago
