Author	SHA1	Message	Date
Brian Brazil	0ec71442cd	Storage: Tell users how to avoid crash recovery. ... If users see the crash recovery error, the chances are they aren't shutting down Prometheus correctly. Telling them how to do so will help them debug and fix the problem.	9 years ago
Laurie Malau	20ad403587	Don't warn/increment metric upon equal timestamps during append. ... Perhaps it would be even better to still warn in case the sample value has changed but the timestamps are equal, but we don't have efficient access to the last value.	9 years ago
Will Rouesnel	7810448dbe	Add proxy_url parameter to allow specifying per-job HTTP proxy servers ... Allow scrape_configs to have an optional proxy_url option which specifies a proxy to be used for all connections to hosts in that config. Internally this modifies the various client functions to take a *url.URL pointer which currently must point to an HTTP proxy (but has been left open-ended to allow the url format to be extended to support others, such as maybe SOCKS if needed).	9 years ago
Julius Volz	517badc21d	Only do regex lookups when there was no equality match. ... For the label matching index-based preselection phase, don't do an OR between equality and non-equality matchers. Execute only one of the two (with equality matchers preferred when present). Fixes https://github.com/prometheus/prometheus/issues/924	9 years ago
beorn7	699946bf32	Fix chunk desc loading. ... If all samples in consecutive chunks have the same timestamp, the way we used to load chunks will fail. With this change, the persist watermark is used to load the right amount of chunkDescs from disk. This bug is a possible reason for the rare storage corruption we have observed.	10 years ago

beorn7	ff08f0b6fe	storage: ensure timestamp monotonicity within series. ... Fixes https://github.com/prometheus/prometheus/issues/481 While doing so, clean up and fix a few other things: - Fix `go vet` warnings (@fabxc to blame ;). - Fix a racey problem with unarchiving: Whenever we unarchive a series, we essentially want to do something with it. However, until we have done something with it, it appears like a series that is ready to be archived or even purged. So e.g. it would be ignored during checkpointing. With this fix, we always load the chunkDescs upon unarchiving. This is wasteful if we only want to add a new sample to an archived time series, but the (presumably more common) case where we access an archived time series in a query doesn't become more expensive. - The change above streamlined the getOrCreateSeries ond newMemorySeries flow. Also, the modTime is now always set correctly. - Fix the leveldb-backed implementation of KeyValueStore.Delete. It had the wrong behavior of still returning true, nil if a non-existing key has been passed in.	10 years ago
Julius Volz	acbc2b8cb6	storage: Fix float->uint conversions on some compilers. ... See https://github.com/prometheus/prometheus/issues/887, which will at least be partially fixed by this. From the spec https://golang.org/ref/spec#Conversions: "In all non-constant conversions involving floating-point or complex values, if the result type cannot represent the value the conversion succeeds but the result value is implementation-dependent." This ended up setting the converted values to 0 on Debian's Go 1.4.2 compiler, at least on 32-bit Debians.	10 years ago

Fabian Reinartz	dc7d27ab9a	retrieval: add honor label handling and parametrized querying. ... This commit adds the honor_labels and params arguments to the scrape config. This allows to specify query parameters used by the scrapers and handling scraped labels with precedence.	10 years ago
beorn7	9016917d1c	Increment dirty counter only if setDirty(true) is called. ... Currently, we increment the counter even if setDirty(false) is called, which sets the storage clean.	10 years ago
Fabian Reinartz	1eff186555	Merge pull request #810 from prometheus/fabxc/lmatch ... Match empty labels.	10 years ago
Fabian Reinartz	5b91ea9b36	storage: improve label matching and allow unset matching. ... Matching of empty labels now also matches metrics where the label was not explicitly set to the empty string.	10 years ago

Fabian Reinartz	aff01e29c3	Limit retrievable samples to retention window. ... The storage does not delete data immediately after the retention period. We don't want to retrieve this data as it causes artifacts.	10 years ago

Fabian Reinartz	6e319532cf	Read from indexing queue during crash recovery. ... Change #704 introduced a regression that started reading the queue only after potential crash recovery. When more than the queue capacity was indexed, Prometheus deadlocked.	10 years ago

beorn7	3b9c421a69	Weed out all the [Gg]et* method names. ... The only exception is getNumChunksToPersist to avoid naming the struct member numChunksToPersist in a weird way.	10 years ago
Julius Volz	267fd34156	Switch Prometheus to use github.com/prometheus/log. ... This change is conceptually very simple, although the diff is large. It switches logging from "github.com/golang/glog" to "github.com/prometheus/log", while not actually changing any log messages. V(1)-style logging has been changed to be log.Debug*().	10 years ago
