beorn7	8fa1560e48	Fix a very special case of handling the checkpoint timer	10 years ago
beorn7	4d1f7b49b6	Fix a race condition in calculatePersistenceUrgencyScore	10 years ago
beorn7	ef3ab96111	Populate first and last time in the chunk descriptor earlier ... The First time is kind of trivial as we always know it when we create a new chunkDesc. The last time is only know when the chunk is closed, so we have to set it at that time. The change saves a lot of digging down into the chunk itself. Especially the last time is relative expensive as it involves the creation of an iterator. The first time access now doesn't require locking, which is also a nice gain.	10 years ago
beorn7	9a3edea477	Remove race condition from TestRetentionCutoff	10 years ago
Julius Volz	9b6d69610a	Fix various typos in comments. ... Helpfully reported by https://goreportcard.com/report/github.com/prometheus/prometheus :)	10 years ago
Fabian Reinartz	1f877f3d2a	Fix deadlock, structure target logging	10 years ago
Fabian Reinartz	59f1e722df	Return error on sample appending	10 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.	10 years ago
beorn7	87ef24cd25	Add instrumentation and refactor things around "rushed mode"	11 years ago
beorn7	a2cd479058	Fix calculation of chunks to persist after restart ... Since we are not overestimating the number of chunks to persist anymore, this commit also adjusts the default value for -storage.local.memory-chunks. Update of documentation will follow.	11 years ago
beorn7	972d94433a	Introduce a hysteresis for "rushed mode" ... "Rushed mode" is formerly known as "degraded mode", which is changed with this commit, too. The name "degraded" was very misleading. Also, switch into rushed mode if we have too many chunks in memory and an at least reasonable amount of chunks to persist so that speeding up persisting chunks can help.	11 years ago
beorn7	14796bdb60	Improve chunkMaxBatchSize doc comment	11 years ago
beorn7	582af1618c	Streamline chunk writing ... This helps to avoid allocations in the same way we were already doing it during reading.	11 years ago
beorn7	99b9611351	Remove a race condition from TestRetentionCutoff	11 years ago
beorn7	3f4d22e4c7	Update doc comment ... This should have gone into a previous commit, but I forgot to save this particular file.	11 years ago
beorn7	add2ebdd56	Tolerate the lost+found directory in the data directory	11 years ago
beorn7	cb117d8346	Add a series ops metric "purge_on_request" ... It counts series deletions triggered via the API.	11 years ago
beorn7	4221c7de5c	Improve handling of series file truncation ... If only very few chunks are to be truncated from a very large series file, the rewrite of the file is a lorge overhead. With this change, a certain ratio of the file has to be dropped to make it happen. While only causing disk overhead at about the same ratio (by default 10%), it will cut down I/O by a lot in above scenario.	11 years ago
Corentin Chary	7b6c3e556c	Use '.' instead of '=' to separate labels from their values in Graphite ... Using .label=value. was weird to use in Graphite and didn't bring much value.	11 years ago
Corentin Chary	a2e4439086	Add support for remote storage on Graphite ... Allows to use graphite over tcp or udp. Metrics labels and values are used to construct a valid Graphite path in a way that will allow us to eventually read them back and reconstruct the metrics. For example, this metric: model.Metric{ model.MetricNameLabel: "test:metric", "testlabel": "test:value", "testlabel2": "test:value", ) Will become: test:metric.testlabel=test:value.testlabel2=test:value escape.go takes care of escaping values to match Graphite character set, it basically uses percent-encoding as a fallback wich will work pretty will in the graphite/grafana world. The remote storage module also has an optional 'prefix' parameter to prefix all metrics with a path (for example, 'prometheus.'). Graphite URLs are simply in the form tcp://host:port or udp://host:port.	11 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	11 years ago
Fabian Reinartz	e3b6ec9784	Switch to common/log	11 years ago
Julius Volz	dac26cef71	Rename global "labels" config option to "external_labels".	11 years ago
Julius Volz	eeb1da36ac	Fix InfluxDB write support to work with InfluxDB 0.9.x. ... Because the InfluxDB client library currently pulls in multiple MBs of unnecessary dependencies, I have modified and cut up the vendored version to only pull in the few pieces that are actually needed. On InfluxDB's side, this dependency issue is tracked in: https://github.com/influxdb/influxdb/issues/3447 Hopefully, it will be resolved soon. If a password is needed for InfluxDB, it may be supplied via the INFLUXDB_PW environment variable.	11 years ago
Julius Volz	5f77fce578	Improve remote storage queue manager metrics.	11 years ago
beorn7	22d3a4311a	Increase waiting time in TestEvictAndLoadChunkDescs ... The test had become flaky with Go1.5. Theory here is that with Go1.5.x, sleeping for 10ms might not be enough to wake up another goroutine, possibly because it is used for GC. 50ms should always be enough due to GC pause guarantees with the new GC.	11 years ago
Julius Volz	af513468eb	Fix some dead code, missing error checks, shadowings. ... I applied https://medium.com/@jgautheron/quality-pipeline-for-go-projects-497e34d6567 and was greeted with a deluge of warnings, most of which were not applicable or really fixable realistically. These are some of the first ones I decided to fix.	11 years ago
beorn7	daeccdd0e9	Fix DropMetricsForFingerprints ... It now deletes the series file also for archived series. Also, fix a naming error in a doc comment.	11 years ago
Julius Volz	6774a73878	Fix error checking and logging around checkpointing.	11 years ago
Julius Volz	011faf9057	Fix typo in comment.	11 years ago
Fabian Reinartz	8fa719f778	Attach global labels to remote storage samples	11 years ago
Dieter Plaetinck	e1dacc56e6	fix comment. ... the sample doesn't get appended to the list of sampleappenders.	11 years ago
Julius Volz	995d3b831d	Fix most golint warnings. ... This is with `golint -min_confidence=0.5`. I left several lint warnings untouched because they were either incorrect or I felt it was better not to change them at the moment.	11 years ago
Julius Volz	963ad82dcb	Fix "go vet" errors. ... I ignored all errors of the type "composite literal uses unkeyed fields". Most of them are wrong because of https://github.com/golang/go/issues/9171.	11 years ago
Fabian Reinartz	d6b8da8d43	Switch promql types to common/model	11 years ago
Fabian Reinartz	e061595352	Move COWMetric into storage/metric package	11 years ago

Brian Brazil	fdf0d0642e	Cast value to float, as that's what the console templates expect.	11 years ago
Fabian Reinartz	1535ef1457	Replace metric.SamplePair with model.SamplePair	11 years ago
Fabian Reinartz	c9d396f476	Replace metric.LabelPair with model.LabelPair	11 years ago
Fabian Reinartz	438e232c9b	Fix grouping of import blocks	11 years ago
Fabian Reinartz	306e8468a0	Switch from client_golang/model to common/model	11 years ago
Julius Volz	f65ef1ed10	Fix wording in shutdown warning.	11 years ago
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.	11 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.	11 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).	11 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	11 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.	11 years ago
