Author	SHA1	Message	Date
Frederic Branczyk	7714b9c781	move relabeling functionality to its own package ... also remove the returned error as it was always nil	9 years ago
Gregory G. Tseng	7997c14b0d	Add ServerName into TLS Config	10 years ago
Fabian Reinartz	ddc74f712b	Add sortable target list	10 years ago
Fabian Reinartz	1ede7b9d72	Consolidate TargetStatus into Target. ... This commit simplifies the TargetHealth type and moves the target status into the target itself. This also removes a race where error and last scrape time could have been out of sync.	10 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.	10 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.	10 years ago
Fabian Reinartz	02f635dc24	Remove interval/timeout from Target internals	10 years ago
Fabian Reinartz	775316f8d2	Move appender construction from Target to scrapePool	10 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.	10 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.	10 years ago
Fabian Reinartz	cebba3efbb	Simplify and fix TargetManager reloading	10 years ago
Fabian Reinartz	da99366f85	Consolidate Target.Update into constructor. ... The Target.Update method is no longer needed.	10 years ago
Fabian Reinartz	d15adfc917	Preserve target state across reloads. ... This commit moves Scraper handling into a separate scrapePool type. TargetSets only manage TargetProvider lifecycles and sync the retrieved updates to the scrapePool. TargetProviders are now expected to send a full initial target set within 5 seconds. The scrapePools preserve target state across reloads and only drop targets after the initial set was synced.	10 years ago
beorn7	33a50e69f7	Fix a deadlock ... Double acquisition of the RLock usually doesn't blow up, but if the write lock is called for between the two RLock's, we are deadlocked. This deadlock does not exist in release-0.17, BTW.	10 years ago
Fabian Reinartz	6df1f49c13	Remove fullLabels method and fix target updating ... With recent changes to a Target's internal data representation updating by fullLabels() assigns the additional default instance label. This breaks target identity comparison and causes identical targets from service discovery to be constantly swapped.	10 years ago
Fabian Reinartz	66767121ab	Handle scrape timeout on request. ... For historic reasons we were enforcing a timeout directly via the TCP dialer. This is no longer necessary for quite a while now. Switching to context.Context will allow us to properly terminate requests on shutdown as well.	10 years ago
Julius Volz	293486c7b1	Remove old superfluous calls to setLastScrape(). ... This is called from within the scrape()->report() flow now. See https://github.com/prometheus/prometheus/pull/1394/files#r52945817	10 years ago
Fabian Reinartz	463dd3ea06	Refactor target scrape reporting.	10 years ago
Fabian Reinartz	cd28b88b08	Fix wrong EOF error on successful target scraping	10 years ago
Fabian Reinartz	27d71b08d1	Factor out appender wrapping	10 years ago
Fabian Reinartz	fe7e91e2eb	Make scraping offset consistent. ... To evenly distribute scraping load we currently rely on random jittering. This commit hashes over the target's identity and calculates a consistent offset. This also ensures that scrape intervals are constantly spaced between config/target changes.	10 years ago
Fabian Reinartz	a06bc75519	Remove occurrences of 'base' labels	10 years ago
Fabian Reinartz	65eba080a0	Cleanup internal target data	10 years ago
Julius Volz	3728b5872f	Fix target update error handling. ... Fixes https://github.com/prometheus/prometheus/issues/1378	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
Brian Brazil	7a5f019c40	Use up/down in UI for consistency with 'up' metric.	10 years ago
Fabian Reinartz	e3b6ec9784	Switch to common/log	10 years ago
Brian Brazil	b03569267e	retrieval: Add URL parameters to fullLabels too ... Move all the special cases into one map, rather than spreading the logic around.	10 years ago
Fabian Reinartz	327152862c	Update expfmt.NewDecoder usage	10 years ago
Anders Daljord Morken	9fb65a91af	Close HTTP connections on HTTP errors too. ... Move defer resp.Body.Close() up to make sure it's called even when the HTTP request returns something other than 200 or Decoder construction fails. This avoids leaking and eventually running out of file descriptors.	10 years ago
Fabian Reinartz	8456b7e12f	Use go1.5.1	10 years ago
Jimmi Dyson	a1574aa2b3	Move TLS options to scrape config ... Fixes #1013, fixes #989	10 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.	10 years ago
Fabian Reinartz	01834fa528	Move metric modifications into SampleAppenders	10 years ago
Fabian Reinartz	6d0f58dcf3	sanitize scrape health recording code	10 years ago
Fabian Reinartz	25bf5fdaf5	Timeout sample appends	10 years ago
Fabian Reinartz	11a577fcd0	Switch to common/expfmt for extraction	10 years ago
Fabian Reinartz	306e8468a0	Switch from client_golang/model to common/model	10 years ago
Jimmi Dyson	923f8111d4	Initial Kubernetes discovery ... Fixes #904	10 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
Jimmi Dyson	da4c50a6cf	Make scheme relabelable via discovery	11 years ago
Jimmi Dyson	52cf6b3e6e	Configuration options for bearer tokens, client certs & CA certs ... Fixes #918, fixes #917	11 years ago
Brian Brazil	d8875d17d8	Retrieval: Make it possible to relabel query params ... This only allows relabelling the first value for a given parameter, this should be sufficient in practice.	11 years ago
Fabian Reinartz	d53cc7935d	retrieval: avoid race conditions	11 years ago
Julius Volz	d868264bb8	Improve UI of /alerts page. ... Changes to the UI: - "Active Since" timestamps are now human-readable. - Alerting rules are now pretty-printed better. - Labels are no longer just strings, but alert bubbles (like we do on the status page for base labels). - Alert states and target health states are now capitalized in the presentation layer rather than at the source.	11 years ago
Fabian Reinartz	53b9d5917d	web: improve target URL handling and display.	11 years ago
Fabian Reinartz	dc7d27ab9a	retrieval: add honor label handling and parametrized querying. ... This commit adds the honor_labels and params arguments to the scrape config. This allows to specify query parameters used by the scrapers and handling scraped labels with precedence.	11 years ago
Brian Brazil	0dbae36d36	Allow ingested metrics to be relabeled. ... The main purpose of this is to allow for blacklisting of expensive metrics as a tactical option. It could also find uses for renaming and removing labels from federation.	11 years ago
