Bjoern Rabenstein	904acd43da	Add crash recovery. Fix the behavior if preload for non-existent series is requested. Instead of returning an error (which triggers a panic further up), simply count those incidents. They can happen regularly, we just want to know if they happen too frequently because that would mean the indexing is behind or broken.

Bjoern Rabenstein	7a9efc9c59	Fix typo in test. Change-Id: I3c2fd76bc5f50446c58f8ef693d9c6595197feaa	10 years ago
Bjoern Rabenstein	4efc60174b	Tweak and verify a few parameters. Remove TODOs accordingly. Change-Id: Ic062e13b6ae89a9135d3f14011114fe1cca1cef8	10 years ago
Bjoern Rabenstein	5f8e9617ef	Add more tests. Add an end-to-end fuzz and race test. Fix a race exposed by the above. Change-Id: Ifaa39a90cefbde8d4c29bda197cc92592ded21bb	10 years ago
Bjoern Rabenstein	d215e013b7	Fix the weird chunkDesc shuffling bug. The root cause was that after chunkDesc eviction, the offset between memory representation of chunk layout (via chunkDescs in memory) was shiftet against chunks as layed out on disk. Keeping the offset up to date is by no means trivial, so this commit is pretty involved. Also, found a race that for some reason didn't bite us so far: Persisting chunks was completel unlocked, so if chunks were purged on disk at the same time, disaster would strike. However, locking the persisting of chunk revealed interesting dead locks. Basically, never queue under the fp lock. Change-Id: I1ea9e4e71024cabbc1f9601b28e74db0c5c55db8	10 years ago
Bjoern Rabenstein	a617269b12	Avoid unnecessary cloning of the head chunk. Change-Id: I5da774515d5493166a197b5814d0a720628cfaff	10 years ago
Bjoern Rabenstein	f1de5b0c4e	Run checkpointing of in-memory metrics and head chunks periodically. Checkpointing interval is now a command line flag. Along the way, several things were refactored. - Restructure the way the storage is started and stopped.. - Number of series in checkpoint is now a uint64, not a varint. (Breaks old checkpoints, needs wipe!) - More consistent naming and order of methods. Change-Id: I883d9170c9a608ee716bb0ab3d0ded8ca03760d9	10 years ago
Bjoern Rabenstein	74c9b34a5e	Improve storage instrumentation even more. Add gauge for chunks and chunkdescs in memory (backed by a global variable to be used later not only for instrumentation but also for memory management). Refactored instrumentation code once more (instrumentation.go is back :). Change-Id: Ife39947e22a48cac4982db7369c231947f446e17	10 years ago
Julius Volz	c3fcea45e3	Support finer time resolutions than 1 second. Change-Id: I4c5f1d6d2361e841999b23283d1961b1bd0c2859	10 years ago
Julius Volz	0712d738d1	Allow alternative "by"-clause position in grammar. In addition to the existing by-clause syntax: sum(<expression>) by (<labels>) [keeping_extra] ...this allows the following new syntax: sum by (<labels>) [keeping_extra] (<expression>) Both orderings may be used in a single expression. It is up to the users to establish guidelines around their usage. Change-Id: Iba10c9cc5fb6ac62edfcf246d281473e82467992	10 years ago
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. This limit returns up to ~500kB per timeseries, and allows for 60s granularity for a week and 1h granularity for a year. Change-Id: Ie549fc24deb2eecbc6c5d1b6088a548a6b02e849	10 years ago
Brian Brazil	75e37db55b	Don't alert() when a query is aborted, such as when you change the range. Change-Id: I574504f97446ac5f3dda737fe054ae83f17dbbc2	10 years ago
Julius Volz	0e48c18bbf	Allow omitting the metric name in queries. This allows the following expression syntaxes for selecting timeseries: foo (already valid before) foo{} (already valid before) {job="prometheus"} (new, select all timeseries for job "prometheus") Omitting both the metric name and any label matchers ("" or "{}") will still yield a syntax error. To get all timeseries, you could do: {__name__=~"."} or, without relying on knowledge about __metric__: {job=~"."} Change-Id: Ifee000b9ac0184ef6ced18411069c7f2699a2dda	10 years ago

Bjoern Rabenstein	096fa0f8b2	Squash a number of TODOs. - Staleness delta is no a proper function parameter and not replicated from package ast. - Named type 'chunks' replaced by explicit '[]chunk' to avoid confusion. - For the same reason, replaced 'chunkDescs' by '[]*chunkDescs'. - Verified that math.Modf is not a speed enhancement over conversion (actually 5x slower). - Renamed firstTimeField, lastTimeField into chunkFirstTime and chunkLastTime. - Verified unpin() is sufficiently goroutine-safe. - Decided not to update archivedFingerprintToTimeRange upon series truncation and added a rationale why.

Bjoern Rabenstein	ecee5d8281	Fix head chunk persisting and a chunkDesc race condition. - Head chunk persisting only happens in evictOlderThan, so do it there. (With the previous code, it would never happen.) - Raw accesses to chunkDesc.chunk are now done via isEvicted (with locking). Change-Id: I48b07b56dfea4899b50df159b4ea566954396fcd	10 years ago
