Paulin Todev	5752050b42	Scrape metrics can now be registered with a non-default registry. * A registerer is passed to the scrape Manager, and all scrape metrics register with it. * For now the registry which we pass to the scrape Manager is still the global one.

Julius Volz	cb045c0e4b	Fix wording from "jitterSeed" -> "offsetSeed" for server-wide scrape offsets In digital communication, "jitter" usually refers to how much a signal deviates from true periodicity, see https://en.wikipedia.org/wiki/Jitter. The way we are using the "jitterSeed" in Prometheus does not affect the true periodicity at all, but just introduces a constant phase shift (or offset) within the period. So it would be more correct and less confusing to call the "jitterSeed" an "offsetSeed" instead. Signed-off-by: Julius Volz <julius.volz@gmail.com>	2 years ago
Bryan Boreham	b96b89ef8b	Merge pull request #12048 from bboreham/faster-targets Scraping targets are synced by creating the full set, then adding/removing any which have changed. This PR speeds up the process of creating the full set. I added a benchmark for `TargetsFromGroup`; it uses configuration from a typical Kubernetes SD. The crux of the change is to do relabeling inside labels.Builder instead of converting to labels.Labels and back again for every rule. The change is broken into several commits for easier review. This is a breaking change to `scrape.PopulateLabels()`, but `relabel.Process` is left as-is, with a new `relabel.ProcessBuilder` option.	2 years ago

Łukasz Mierzwa	e1b7082008	Show individual scrape pools on /targets page (#11142 ) * Add API endpoints for getting scrape pool names This adds api/v1/scrape_pools endpoint that returns the list of names of all the scrape pools configured. Having it allows to find out what scrape pools are defined without having to list and parse all targets. The second change is adding scrapePool query parameter support in api/v1/targets endpoint, that allows to filter returned targets by only finding ones for passed scrape pool name. Both changes allow to query for a specific scrape pool data, rather than getting all the targets for all possible scrape pools. The problem with api/v1/targets endpoint is that it returns huge amount of data if you configure a lot of scrape pools. Signed-off-by: Łukasz Mierzwa <l.mierzwa@gmail.com> * Add a scrape pool selector on /targets page Current targets page lists all possible targets. This works great if you only have a few scrape pools configured, but for systems with a lot of scrape pools and targets this slow things down a lot. Not only does the /targets page load very slowly in such case (waiting for huge API response) but it also take a long time to render, due to huge number of elements. This change adds a dropdown selector so it's possible to select only intersting scrape pool to view. There's also scrapePool query param that will open selected pool automatically.

xjewer	0d1a69353e	scrape: Add global jitter for HA server (#5181 ) * scrape: Add global jitter for HA server Covers issue in https://github.com/prometheus/prometheus/pull/4926#issuecomment-449039848 where the HA setup become a problem for targets unable to be scraped simultaneously. The new jitter per server relies on the hostname and external labels which necessarily to be uniq. As before, scrape offset will be calculated with regard the absolute time, so even restart/reload doesn't change scrape time per scrape target + prometheus instance. Use fqdn if possible, otherwise fall back to the hostname. It adds extra random seed to calculate server hash to be distinguish on machines with the same hostname, but different DC.

Krasi Georgiev	47a673c3a0	process scrape loops reloading in parallel (#4526 ) The scrape manage receiver's channel now just saves the target sets and another backgorund runner updates the scrape loops every 5 seconds. This is so that the scrape manager doesn't block the receiving channel when it does the long background reloading of the scrape loops. Active and dropped targets are now saved in each scrape pool instead of the scrape manager. This is mainly to avoid races when getting the targets via the web api. When reloading the scrape loops now happens in parallel to speed up the final disared state and this also speeds up the prometheus's shutting down. Also updated some funcs signatures in the web package for consistency. Signed-off-by: Krasi Georgiev <kgeorgie@redhat.com>	6 years ago
