Bryan Boreham	b987afa7ef	labels: simplify call to get Labels from Builder It took a `Labels` where the memory could be re-used, but in practice this hardly ever benefitted. Especially after converting `relabel.Process` to `relabel.ProcessBuilder`. Comparing the parameter to `nil` was a bug; `EmptyLabels` is not `nil` so the slice was reallocated multiple times by `append`. Lastly `Builder.Labels()` now estimates that the final size will depend on labels added and deleted. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago

beorn7	c2e9a151ab	Make all rule links link to the "Console" tab rather than "Graph" Clicking on a rule, either the name or the expression, opens the rule result (or the corresponding expression, repsectively) in the expression browser. This should by default happen in the console tab, as, more often than not, displaying it in the graph tab runs into a timeout.	7 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
