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.	8 years ago

Matt Bostock	926a5ab3dd	rules/manager.go: Fix race between reload and stop ... On one relatively large Prometheus instance (1.7M series), I noticed that upgrades were frequently resulting in Prometheus undergoing crash recovery on start-up. On closer examination, I found that Prometheus was panicking on shutdown. It seems that our configuration management (or misconfiguration thereof) is reloading Prometheus then immediately restarting it, which I suspect is causing this race: Sep 21 15:12:42 host systemd[1]: Reloading prometheus monitoring system.

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	f1ea5bf232	Modify tests to adjust to reverting the /graph changes ... These tests have been added after the /graph changes and therefore already test the new syntax. This commit has to be reverted together with the previous one to get back to the old new state. *sigh*	9 years ago

beorn7	064b57858e	Consistently use the `Seconds()` method for conversion of durations ... This also fixes one remaining case of recording integral numbers of seconds only for a metric, i.e. this will probably fix #1796.	10 years ago

beorn7	45e5775f9b	Add missing logging of out-of-order samples ... So far, out-of-order samples during rule evaluation were not logged, and neither scrape health samples. The latter are unlikely to cause any errors. That's why I'm logging them always now. (It's alway highly irregular should it happen.) For rules, I have used the same plumbing as for samples, just with a different wording in the message to mark them as a result of rule evaluation.	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
Fabian Reinartz	d89c254849	Make copying alerting state safer. ... This considers static labels in the equality of alerts to avoid falsely copying state from a different alert definition with the same name across reloads. To be safe, it also copies the state map rather than just its pointer so that remaining collisions disappear after one evaluation interval.	10 years ago

beorn7	ec08c9a391	Rework the way to communicate backpressure (AKA suspended ingestion) ... This gives up on the idea to communicate throuh the Append() call (by either not returning as it is now or returning an error as suggested/explored elsewhere). Here I have added a Throttled() call, which has the advantage that it can be called before a whole _batch_ of Append()'s. Scrapes will happen completely or not at all. Same for rule group evaluations. That's a highly desired behavior (as discussed elsewhere). The code is even simpler now as the whole ingestion buffer could be removed. Logging of throttled mode has been streamlined and will create at most one message per minute.	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	6eee86dce8	Terminate rule groups during initial sleep ... When an evaluation group runs initially, it waits a deterministic amount of time. During that time it also has to accept a termination singnal so shutdown doesn't hang during the first evaluation iteration after a configuration reload. Fixes #1307	10 years ago
