Brian Brazil	37bc607e96	Rework sample limit to work for 2.0 Correctly update reported series. Increment prometheus_target_scrapes_exceeded_sample_limit_total. Add back unittests. Ignore stale markers when calculating sample limit. Fixes #2770	8 years ago

Fabian Reinartz	d289dc55c3	storage: update TSDB	8 years ago
Brian Brazil	bf38963118	Plumb through logger with target field to scrape loop.	8 years ago
Brian Brazil	d532272520	Add stalemarkers to synthetic series too when target stops.	8 years ago
Brian Brazil	b87d3ca9ea	Create stale markers when a target is stopped. When a target is no longer returned from SD stop() is called. However it may be recreated before the next scrape interval happens. So we wait to set stalemarkers until the scrape of the new target would have happened and been ingested, which is 2 scrape intervals. If we're shutting down the context will be cancelled, so return immediately rather than holding things up for potentially minutes waiting to safely set stalemarkers no newer than now. If the server starts immediately back up again all is well. If not, we're missing some stale markers.	8 years ago
Brian Brazil	3c45400130	Don't fail scrape if one sample violates ordering. In Prometheus 1.x one sample that is out of order or that has a duplicate timestamp is discarded, and the rest of the scrape ingestion continues on. This will now also be true for 2.0.	8 years ago
Brian Brazil	fd5c5a50a3	Add stale markers on parse error. If we fail to parse the result of a scrape, we should treat that as a failed scrape and add stale markers.	8 years ago
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
Brian Brazil	5060a0fc51	Add unittests for ingestion stale NaNs	8 years ago

Matt Layher	fe4b6693f7	retrieval: add Scrape-Timeout-Seconds header to each scrape request (#2565 ) Fixes #2508.	8 years ago
Fabian Reinartz	1d3cdd0d67	Merge branch 'master' into dev-2.0-rebase	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
beorn7	5dc01202d7	Retrieval: Remove some test lines that fail on Travis only These lines exercise an append in TestScrapeLoopWrapSampleAppender. Arguably, append shouldn't be tested there in the first place. Still it's weird why this fails on Travis: ``` --- FAIL: TestScrapeLoopWrapSampleAppender (0.00s) scrape_test.go:259: Expected count of 1, got 0 scrape_test.go:290: Expected count of 1, got 0 2017/01/07 22:48:26 http: TLS handshake error from 127.0.0.1:50716: read tcp 127.0.0.1:40265->127.0.0.1:50716: read: connection reset by peer FAIL FAIL github.com/prometheus/prometheus/retrieval 3.603s ``` Should anybody ever find out why, please revert this commit accordingly.	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	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

Tobias Schmidt	29ced0090f	Fix common english misspellings	8 years ago
Anders Daljord Morken	95cadd0702	Run scrape loop with interval 1 instead of 0 0 is considered an invalid interval by time.NewTicker() and will cause a panic if control reaches that point. Given the vagaries of timekeeping, this may occasionally happen and make this test unstable.	8 years ago
Julius Volz	97b018d26d	Fix format argument in retrieval test.	9 years ago
Fabian Reinartz	895f2f092f	Fix flaky scrape test t	9 years ago
Fabian Reinartz	50c2f20756	Add targetScraper tests	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	775316f8d2	Move appender construction from Target to scrapePool	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	2bb8ef99d1	Test scrape loop behavior.	9 years ago
