Brian Brazil	c0c7e32e61	Treat a failed scrape as an empty scrape for staleness. If a target has died but is still in SD, we want the previously scraped values to go stale. This would also apply to brief blips.	8 years ago
Brian Brazil	850ea412ad	If an explicit timestamp is provided, bypass staleness.	8 years ago

Tobias Schmidt	368206d2f5	Handle errSeriesDropped correctly If metrics_relabel_configs are used to drop metrics, an errSeriesDropped is returned. This shouldn't be used to return an error at the end of a append() call.	8 years ago

Erdem Agaoglu	8809735d7f	Setting User-Agent header (#2447 )	8 years ago
Fabian Reinartz	cc0ff26f1f	retrieval: handle GZIP compression ourselves The automatic GZIP handling of net/http does not preserve buffers across requests and thus generates a lot of garbage. We handle GZIP ourselves to circumvent this.t	8 years ago
Fabian Reinartz	5772f1a7ba	retrieval/storage: adapt to new interface This simplifies the interface to two add methods for appends with labels or faster reference numbers.	8 years ago
Fabian Reinartz	1d3cdd0d67	Merge branch 'master' into dev-2.0-rebase	8 years ago
Fabian Reinartz	598e2f01c0	retrieval: don't erronously break appending	8 years ago
Fabian Reinartz	c691895a0f	retrieval: cache series references, use pkg/textparse With this change the scraping caches series references and only allocates label sets if it has to retrieve a new reference. pkg/textparse is used to do the conditional parsing and reduce allocations from 900B/sample to 0 in the general case.	8 years ago
Fabian Reinartz	ad9bc62e4c	storage: extend appender and adapt it	8 years ago
Björn Rabenstein	ad40d0abbc	Merge pull request #2288 from prometheus/limit-scrape Add ability to limit scrape samples, and related metrics	8 years ago
beorn7	3610331eeb	Retrieval: Do not buffer the samples if no sample limit configured Also, simplify and streamline the code a bit.	8 years ago
Fabian Reinartz	e631a1260d	retrieval: use separate appender per target	8 years ago
Fabian Reinartz	f8fc1f5bb2	*: migrate ingestion to new batch Appender	8 years ago
Brian Brazil	f421ce0636	Remove label from prometheus_target_skipped_scrapes_total (#2289 ) This avoids it not being intialised, and breaking out by interval wasn't partiuclarly useful. Fixes #2269	8 years ago
Brian Brazil	30448286c7	Add sample_limit to scrape config. This imposes a hard limit on the number of samples ingested from the target. This is counted after metric relabelling, to allow dropping of problemtic metrics. This is intended as a very blunt tool to prevent overload due to misbehaving targets that suddenly jump in sample count (e.g. adding a label containing email addresses). Add metric to track how often this happens. Fixes #2137	8 years ago
Brian Brazil	c8de1484d5	Add scrape_samples_post_metric_relabeling This reports the number of samples post any keep/drop from metric relabelling.	8 years ago
Brian Brazil	06b9df65ec	Refactor and add unittests to scrape result handling.	8 years ago
Brian Brazil	b5ded43594	Allow buffering of scraped samples before sending them to storage.	8 years ago
Fabian Reinartz	200bbe1bad	config: extract SD and HTTPClient configurations	8 years ago

Brian Brazil	64263f280d	Add scrape_samples_scraped to indicate samples scraped. (#2123 )	8 years ago
Matt Bostock	4fc619b605	Scrape: Remove JSON from Accept request header JSON is no longer supported as an exposition format [1] [2] [3]. Remove it from the `Accept` header added to requests when scraping targets. [1]: https://github.com/prometheus/prometheus/blob/master/CHANGELOG.md#100--2016-07-18 [2]: https://prometheus.io/docs/instrumenting/exposition_formats/#historical-versions [3]: https://docs.google.com/document/d/1ZjyKiKxZV83VI9ZKAXRGKaUKK2BIWCT7oiGBKDBpjEY/edit?usp=sharing	8 years ago
Fabian Reinartz	0322c59dc3	retrieval: export NewHTTPClient	8 years ago
beorn7	064b57858e	Consistently use the `Seconds()` method for conversion of durations This also fixes one remaining case of recording integral numbers of seconds only for a metric, i.e. this will probably fix #1796.	9 years ago
beorn7	45e5775f9b	Add missing logging of out-of-order samples So far, out-of-order samples during rule evaluation were not logged, and neither scrape health samples. The latter are unlikely to cause any errors. That's why I'm logging them always now. (It's alway highly irregular should it happen.) For rules, I have used the same plumbing as for samples, just with a different wording in the message to mark them as a result of rule evaluation.	9 years ago
beorn7	d566808d40	Bring back logging of discarded samples But only on DEBUG level. Also, count and report the two cases of out-of-order timestamps on the one hand and same timestamp but different value on the other hand separately.	9 years ago
Fabian Reinartz	769389e559	Fix potential race in ctx intialization	9 years ago
Tobias Schmidt	e82ef154ee	Remove unused code leftovers	9 years ago
stuart nelson	dbe5d18b6e	Instrument scrape pool `sync()` Instruments: - duration - count	9 years ago
stuart nelson	a1ee77601a	Instrument the duration of the `reload` function	9 years ago
Fabian Reinartz	0d7105abee	Remove scrape config from Target. This commit removes the scrapeConfig entirely from Target. All identity defining parameters are thus immutable now and the mutex can be removed.. Target identity is now correctly defined by the labels and the full URL. This in particular includes URL parameters that are not specified in the label set. Fingerprint is also removed from hash to remove an unnecessary tight coupling to the common/model package.	9 years ago
Fabian Reinartz	75681b691a	Extract HTTP client from Target. The HTTP client is the same across all targets with the same scrape configuration. Thus, this commit moves it into the scrape pool.	9 years ago
Fabian Reinartz	9bea27ae8a	Add scraping tests	9 years ago
Fabian Reinartz	76a8c6160d	Deduplicate targets in scrape pool. With this commit the scrape pool deduplicates incoming targets before scraping them. This way multiple target providers can produce the same target but it will be scraped only once.	9 years ago
Fabian Reinartz	84f74b9a84	Apply new scrape config on reload. This commit updates a target set's scrape configuration on reload. This will cause all running scrape loops to be stopped and started again with new parameters.	9 years ago
Fabian Reinartz	02f635dc24	Remove interval/timeout from Target internals	9 years ago
Fabian Reinartz	775316f8d2	Move appender construction from Target to scrapePool	9 years ago
Fabian Reinartz	fbe251c2df	Fix scrape interval length calculation	9 years ago
Fabian Reinartz	1a3253e8ed	Make scrape time unambigious. This commit changes the scraper interface to accept a timestamp so the reported timestamp by the caller and the timestamp attached to samples does not differ.	9 years ago
Fabian Reinartz	c7bbe95597	Remove outdated target tests	9 years ago
Fabian Reinartz	05de8b7f8d	Extract target scraping into scrape loop. This commit factors out the scrape loop handling into its own data structure. For the transition it will be directly attached to the target.	9 years ago
Fabian Reinartz	5bfa4cdd46	Simplify target update handling. We group providers by their scrape configuration. Each provider produces target groups with an unique identifier. On stopping a set of target providers we cancel the target providers, stop scraping the targets and wait for the scrapers to finish. On configuration reload all provider sets are stopped and new ones are created. This will make targets disappear briefly on configuration reload. Potentially scrapes are missed but due to the consistent scrape intervals implemented recently, the impact is minor.	9 years ago
