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	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	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Fabian Reinartz	c7bbe95597	Remove outdated target tests	9 years ago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
