Julius Volz	4df5c7ab18	Optimize label matcher memory and runtime behavior. This optimizes the runtime and memory allocation behavior for label matchers other than type "Equal". Instead of creating a new set for every union of fingerprints, this simply adds new fingerprints to the existing set to achieve the same effect. The current behavior made a production Prometheus unresponsive when running a NotEqual match against the "instance" label (a label with high value cardinality).

Julius Volz	1b29975865	Fix RWLock memory storage deadlock. This fixes https://github.com/prometheus/prometheus/issues/390 The cause for the deadlock was a lock semantic in Go that wasn't obvious to me when introducing this bug: http://golang.org/pkg/sync/#RWMutex.Lock Key phrase: "To ensure that the lock eventually becomes available, a blocked Lock call excludes new readers from acquiring the lock." In the memory series storage, we have one function (GetFingerprintsForLabelMatchers) acquiring an RLock(), which calls another function also acquiring the same RLock() (GetLabelValuesForLabelName). That normally doesn't deadlock, unless a Lock() call from another goroutine happens right in between the two RLock() calls, blocking both the Lock() and the second RLock() call from ever completing. GoRoutine 1 GoRoutine 2 ====================================== RLock() ... Lock() [DEADLOCK] RLock() [DEADLOCK] Unlock() RUnlock() RUnlock() Testing deadlocks is tricky, but the regression test I added does reliably detect the deadlock in the original code on my machine within a normal concurrent reader/writer run duration of 250ms.

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	c7c0b33d0b	Add regex-matching support for labels. There are four label-matching ops for selecting timeseries now: - Equal: = - NotEqual: != - RegexMatch: =~ - RegexNoMatch: !~ Instead of looking up labels by a simple clientmodel.LabelSet (basically an equals op for every key/value pair in the set), timeseries fingerprint selection is now done via a list of metric.LabelMatchers.

Julius Volz	7a577b86b7	Fix interval op special case. In the case that a getValuesAtIntervalOp's ExtractSamples() is called with a current time after the last chunk time, we return without extracting any further values beyond the last one in the chunk (correct), but also without advancing the op's time (incorrect). This leads to an infinite loop in renderView(), since the op is called repeatedly without ever being advanced and consumed. This adds handling for this special case. When detecting this case, we immediately set the op to be consumed, since we would always get a value after the current time passed in if there was one.

Bjoern Rabenstein	c3b282bd14	Add regression tests for 'loop until op is consumed' bug. - Most of this is the actual regression test in tiered_test.go. - Working on that regression tests uncovered problems in tiered_test.go that are fixed in this commit. - The 'op.consumed = false' line added to freelist.go was actually not fixing a bug. Instead, there was no bug at all. So this commit removes that line again, but adds a regression test to make sure that the assumed bug is indeed not there (cf. freelist_test.go). - Removed more code duplication in operation.go (following the same approach as before, i.e. embedding op type A into op type B if everything in A is the same as in B with the exception of String() and ExtractSample()). (This change make struct literals for ops more clunky, but that only affects tests. No code change whatsoever was necessary in the actual code after this refactoring.) - Fix another op leak in tiered.go. Change-Id: Ia165c52e33290ad4f6aba9c83d92318d4f583517	11 years ago
Julius Volz	86fc13a52e	Convert metric.Values to slice of values. The initial impetus for this was that it made unmarshalling sample values much faster.

Some of the smaller append examples take minimally longer, but the cost seems to get amortized over larger appends, so I'm not worried about these. Also, we're currently not bottlenecked on the write path and have plenty of other optimizations available in that area if it becomes necessary.

Julius Volz	d6827b6898	Fix memory series indexing bug. This fixes https://github.com/prometheus/prometheus/issues/381. For any stale series we dropped from memory, this bug caused us to also drop any other series from the labelpair->fingerprints memory index if they had any label/value-pairs in common with the intentionally dropped series. To fix this issue more easily, I converted the labelpair->fingerprints index map values to a utility.Set of clientmodel.Fingerprints. This makes handling this index much easier in general.

Bjoern Rabenstein	9ea9189dd1	Remove the multi-op-per-fingerprint capability. Currently, rendering a view is capable of handling multiple ops for the same fingerprint efficiently. However, this capability requires a lot of complexity in the code, which we are not using at all because the way we assemble a viewRequest will never have more than one operation per fingerprint. This commit weeds out the said capability, along with all the code needed for it. It is still possible to have more than one operation for the same fingerprint, it will just be handled in a less efficient way (as proven by the unit tests). As a result, scanjob.go could be removed entirely. This commit also contains a few related refactorings and removals of dead code in operation.go, view,go, and freelist.go. Also, the docstrings received some love. Change-Id: I032b976e0880151c3f3fdb3234fb65e484f0e2e5	11 years ago
Bjoern Rabenstein	e11e8c7a23	Unify LevelDB.Options. We have seven different types all called like LevelDB.Options. One of them is the plain LevelDBOptions. All others are just wrapping that type without adding anything except clunkier handling. If there ever was a plan to add more specific options to the various LevelDB.*Options types, history has proven that nothing like that is going to happen anytime soon. To keep the code a bit shorter and more focused on the real (quite significant) complexities we have to deal with here, this commit reduces all uses of LevelDBOptions to the actual LevelDBOptions type. 1576 fewer characters to read...

Bjoern Rabenstein	6bc083f38b	Major code cleanup in storage. - Mostly docstring fixed/additions. (Please review these carefully, since most of them were missing, I had to guess them from an outsider's perspective. (Which on the other hand proves how desperately required many of these docstrings are.)) - Removed all uses of new(...) to meet our own style guide (draft). - Fixed all other 'go vet' and 'golint' issues (except those that are not fixable (i.e. caused by bugs in or by design of 'go vet' and 'golint')). - Some trivial refactorings, like reorder functions, minor renames, ... - Some slightly less trivial refactoring, mostly to reduce code duplication by embedding types instead of writing many explicit forwarders. - Cleaned up the interface structure a bit. (Most significant probably the removal of the View-like methods from MetricPersistenc. Now they are only in View and not duplicated anymore.) - Removed dead code. (Probably not all of it, but it's a first step...) - Fixed a leftover in storage/metric/end_to_end_test.go (that made some parts of the code never execute (incidentally, those parts were broken (and I fixed them, too))).

Julius Volz	fd2158e746	Store copy of metric during fingerprint caching Problem description: ==================== If a rule evaluation referencing a metric/timeseries M happens at a time when M doesn't have a memory timeseries yet, looking up the fingerprint for M (via TieredStorage.GetMetricForFingerprint()) will create a new Metric object for M which gets both: a) attached to a new empty memory timeseries (so we don't have to ask disk for the Metric's fingerprint next time), and b) returned to the rule evaluation layer. However, the rule evaluation layer replaces the name label (and possibly other labels) of the metric with the name of the recorded rule. Since both the rule evaluator and the memory storage share a reference to the same Metric object, the original memory timeseries will now also be incorrectly renamed. Fix: ==== Instead of storing a reference to a shared metric object, take a copy of the object when creating an empty memory timeseries for caching purposes.

Julius Volz	d5ef0c64dc	Merge "Add optional sample replication to OpenTSDB."	11 years ago
Julius Volz	61d26e8445	Add optional sample replication to OpenTSDB. Prometheus needs long-term storage. Since we don't have enough resources to build our own timeseries storage from scratch ontop of Riak, Cassandra or a similar distributed datastore at the moment, we're planning on using OpenTSDB as long-term storage for Prometheus. It's data model is roughly compatible with that of Prometheus, with some caveats. As a first step, this adds write-only replication from Prometheus to OpenTSDB, with the following things worth noting: 1) I tried to keep the integration lightweight, meaning that anything related to OpenTSDB is isolated to its own package and only main knows about it (essentially it tees all samples to both the existing storage and TSDB). It's not touching the existing TieredStorage at all to avoid more complexity in that area. This might change in the future, especially if we decide to implement a read path for OpenTSDB through Prometheus as well. 2) Backpressure while sending to OpenTSDB is handled by simply dropping samples on the floor when the in-memory queue of samples destined for OpenTSDB runs full. Prometheus also only attempts to send samples once, rather than implementing a complex retry algorithm. Thus, replication to OpenTSDB is best-effort for now. If needed, this may be extended in the future. 3) Samples are sent in batches of limited size to OpenTSDB. The optimal batch size, timeout parameters, etc. may need to be adjusted in the future. 4) OpenTSDB has different rules for legal characters in tag (label) values. While Prometheus allows any characters in label values, OpenTSDB limits them to a to z, A to Z, 0 to 9, -, _, . and /. Currently any illegal characters in Prometheus label values are simply replaced by an underscore. Especially when integrating OpenTSDB with the read path in Prometheus, we'll need to reconsider this: either we'll need to introduce the same limitations for Prometheus labels or escape/encode illegal characters in OpenTSDB in such a way that they are fully decodable again when reading through Prometheus, so that corresponding timeseries in both systems match in their labelsets.

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
