Anders Daljord Morken	e9885ecb94	Bugfix: Avoid divide-by-zero panic on query_range?step=0	8 years ago
Julius Volz	3bfec97d46	Make the storage interface higher-level. ... See discussion in https://groups.google.com/forum/#!topic/prometheus-developers/bkuGbVlvQ9g The main idea is that the user of a storage shouldn't have to deal with fingerprints anymore, and should not need to do an individual preload call for each metric. The storage interface needs to be made more high-level to not expose these details. This also makes it easier to reuse the same storage interface for remote storages later, as fewer roundtrips are required and the fingerprint concept doesn't work well across the network. NOTE: this deliberately gets rid of a small optimization in the old query Analyzer, where we dedupe instants and ranges for the same series. This should have a minor impact, as most queries do not have multiple selectors loading the same series (and at the same offset).	8 years ago

beorn7	da8cb10b43	Partition the status tab into items in a dropdown ... I got feedback from different sources about rules and targets being too heavy in the status tab if their are lots of them. This change also allows for more fine-granular locking.	9 years ago
Julius Volz	0c1e7a5b00	Support time range in /api/v1/series endpoint. ... This adds optional "start" and "end" form values that may be used to restrict the time range of returned series. Fixes https://github.com/prometheus/prometheus/issues/1542	9 years ago
Jonathan Boulle	38098f8c95	Add missing license headers ... Prometheus is Apache 2 licensed, and most source files have the appropriate copyright license header, but some were missing it without apparent reason. Correct that by adding it.	9 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".	9 years ago
beorn7	836f1db04c	Improve MetricsForLabelMatchers ... WIP: This needs more tests. It now gets a from and through value, which it may opportunistically use to optimize the retrieval. With possible future range indices, this could be used in a very efficient way. This change merely applies some easy checks, which should nevertheless solve the use case of heavy rule evaluations on servers with a lot of series churn. Idea is the following: - Only archive series that are at least as old as the headChunkTimeout (which was already extremely unlikely to happen). - Then maintain a high watermark for the last archival, i.e. no archived series has a sample more recent than that watermark. - Any query that doesn't reach to a time before that watermark doesn't have to touch the archive index at all. (A production server at Soundcloud with the aforementioned series churn and heavy rule evaluations spends 50% of its CPU time in archive index lookups. Since rule evaluations usually only touch very recent values, most of those lookup should disappear with this change.) - Federation with a very broad label matcher will profit from this, too. As a byproduct, the un-needed MetricForFingerprint method was removed from the Storage interface.	9 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).	9 years ago

Fabian Reinartz	33aab4169c	Anchor regexes in vector matching ... This commit makes the regex behavior of vector matching consistent with configuration and label_replace() by anchoring it. Fixes #1200	9 years ago
Julius Volz	0088aa4d45	Merge pull request #1132 from prometheus/fix-quoting-and-escaping ... Support escape sequences in strings and add raw strings	9 years ago
Julius Volz	46c5260761	Support escape sequences in strings and add raw strings. ... This adapts some functionality from the Go standard library for string literal lexing and unquoting/unescaping. The following string types are now supported: Double- or single-quoted strings: These support all escape sequences that Go supports in double-quoted string literals. The difference is that Prometheus also has single-quoted strings (instead of single-quoted runes in Go). Raw newlines are not allowed. Backtick-quoted raw strings: Strings quoted in backticks are treated as raw strings just like in Go and may contain raw newlines and other special characters directly.

Brian Brazil	f114bbd4e7	Make query_range more robust. ... Gracefully handle decimal values, by truncating them. Limit amount of steps, to avoid accidentally pulling too much data.

Julius Volz	21cafe6cd7	Only evict memory series after they are on disk. ... This fixes the problem where samples become temporarily unavailable for queries while they are being flushed to disk. Although the entire flushing code could use some major refactoring, I'm explicitly trying to do the minimal change to fix the problem since there's a whole new storage implementation in the pipeline.

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
Conor Hennessy	eba01d1119	Remove usage of gorest. ... Due to on going issues, we've decided to remove gorest. It started with gorest not being thread-safe (it does introspection to create a new handler which is an easy process to mess up with multiple threads of execution): https://code.google.com/p/gorest/issues/detail?id=15 While the issue has been marked fixed, it looks like the patch has introduced more problems than the original issue and simply doesn't work properly. I'm not sure the behaviour was thought through properly. If a new instance is needed every request then a handler-factory is needed or the library needs to set expectations about how the new objects should interact with their constructor state. While it was tempting to try out another routing library, I think for now it's better to use dumb vanilla Go routing. At least until we decide which URL format we intend to standardize on.

Julius Volz	51689d965d	Add debug timers to instant and range queries. ... This adds timers around several query-relevant code blocks. For now, the query timer stats are only logged for queries initiated through the UI. In other cases (rule evaluations), the stats are simply thrown away.

Matt T. Proud	e86f4d9dfd	Convert time readers to represent time in UTC. ... Go's time.Time represents time as UTC in its fundamental data type. That said, when using ``time.Unix(...)``, it sets the zone for the time representation to the local. Unfortunately with diagnosis and our tests, it is a PITA to jump between various zones, even though the serialized version remains the same. To keep things easy, all places where times are generated or read are converted into UTC. These conversions are cheap, for ``Time.In`` merely changes a pointer reference in the struct, nothing more. This enables me to diagnose test failures with fixture data very easily.	12 years ago
