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

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.

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.	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

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.	9 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.	9 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.	9 years ago

Julius Volz	fcff35b43e	Consolidate external reachability flags into one. ... Besides fixing https://github.com/prometheus/prometheus/issues/805 by making the entire externally reachable server URL configurable, this adds tests for the "globalURL" template function and makes it easier to test other such functions in the future. This breaks the `web.Hostname` flag (and introduces `web.external-url`). This flag is likely only used by few users, so I hope that's justifiable.

Julius Volz	01f652cb4c	Separate storage implementation from interfaces. ... This was initially motivated by wanting to distribute the rule checker tool under `tools/rule_checker`. However, this was not possible without also distributing the LevelDB dynamic libraries because the tool transitively depended on Levigo: rule checker -> query layer -> tiered storage layer -> leveldb This change separates external storage interfaces from the implementation (tiered storage, leveldb storage, memory storage) by putting them into separate packages: - storage/metric: public, implementation-agnostic interfaces - storage/metric/tiered: tiered storage implementation, including memory and LevelDB storage. I initially also considered splitting up the implementation into separate packages for tiered storage, memory storage, and LevelDB storage, but these are currently so intertwined that it would be another major project in itself. The query layers and most other parts of Prometheus now have notion of the storage implementation anymore and just use whatever implementation they get passed in via interfaces. The rule_checker is now a static binary :) Change-Id: I793bbf631a8648ca31790e7e772ecf9c2b92f7a0	11 years ago

Julius Volz	740d448983	Use custom timestamp type for sample timestamps and related code. ... So far we've been using Go's native time.Time for anything related to sample timestamps. Since the range of time.Time is much bigger than what we need, this has created two problems: - there could be time.Time values which were out of the range/precision of the time type that we persist to disk, therefore causing incorrectly ordered keys. One bug caused by this was: https://github.com/prometheus/prometheus/issues/367 It would be good to use a timestamp type that's more closely aligned with what the underlying storage supports. - sizeof(time.Time) is 192, while Prometheus should be ok with a single 64-bit Unix timestamp (possibly even a 32-bit one). Since we store samples in large numbers, this seriously affects memory usage. Furthermore, copying/working with the data will be faster if it's smaller. *MEMORY USAGE RESULTS* Initial memory usage comparisons for a running Prometheus with 1 timeseries and 100,000 samples show roughly a 13% decrease in total (VIRT) memory usage. In my tests, this advantage for some reason decreased a bit the more samples the timeseries had (to 5-7% for millions of samples). This I can't fully explain, but perhaps garbage collection issues were involved. *WHEN TO USE THE NEW TIMESTAMP TYPE* The new clientmodel.Timestamp type should be used whenever time calculations are either directly or indirectly related to sample timestamps. For example: - the timestamp of a sample itself - all kinds of watermarks - anything that may become or is compared to a sample timestamp (like the timestamp passed into Target.Scrape()). When to still use time.Time: - for measuring durations/times not related to sample timestamps, like duration telemetry exporting, timers that indicate how frequently to execute some action, etc. *NOTE ON OPERATOR OPTIMIZATION TESTS* We don't use operator optimization code anymore, but it still lives in the code as dead code. It still has tests, but I couldn't get all of them to pass with the new timestamp format. I commented out the failing cases for now, but we should probably remove the dead code soon. I just didn't want to do that in the same change as this. Change-Id: I821787414b0debe85c9fffaeb57abd453727af0f	11 years ago
