Fabian Reinartz	499f4af4aa	Test target URL	9 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.	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	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Fabian Reinartz	c7bbe95597	Remove outdated target tests	9 years ago
Fabian Reinartz	da99366f85	Consolidate Target.Update into constructor. The Target.Update method is no longer needed.	9 years ago
Fabian Reinartz	463dd3ea06	Refactor target scrape reporting.	9 years ago
Fabian Reinartz	27d71b08d1	Factor out appender wrapping	9 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.	9 years ago
Fabian Reinartz	a06bc75519	Remove occurrences of 'base' labels	9 years ago
Fabian Reinartz	65eba080a0	Cleanup internal target data	9 years ago
Julius Volz	3728b5872f	Fix target update error handling. Fixes https://github.com/prometheus/prometheus/issues/1378	9 years ago
Björn Rabenstein	9ea3897ea7	Merge pull request #1354 from prometheus/beorn7/storage Rework the way to communicate backpressure (AKA suspended ingestion)	9 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.	9 years ago
beorn7	a7408bfb47	Unify duration parsing It's actually happening in several places (and for flags, we use the standard Go time.Duration...). This at least reduces all our home-grown parsing to one place (in model).	9 years ago
Brian Brazil	ba6688bfce	retrieval: Reduce flakiness of TestTargetRunScraperScrapes	9 years ago
Brian Brazil	50258929ac	Retrieval: Show error message for failed test scrape This is flaky, and I suspect it was due the to I/O timeout that I've already fixed. In case that wasn't it, display the error should it happen again.	9 years ago
Brian Brazil	93145b960a	retrieval: Reduce flakiness of target tests Bump timeouts of tests where we don't want I/O timeouts. Adjust the full channel test to be much more reliable, by reducing the ingestion timeout from 1ms to 0.	9 years ago
Jimmi Dyson	a1574aa2b3	Move TLS options to scrape config Fixes #1013, fixes #989	9 years ago
Julius Volz	f63a899744	Change config regexes to full-string matches. This anchors all regular expressions entered via the config to match a full string vs. a substring. THIS IS A BREAKING CHANGE! Fixes part of https://github.com/prometheus/prometheus/issues/996	9 years ago
Julius Volz	963ad82dcb	Fix "go vet" errors. I ignored all errors of the type "composite literal uses unkeyed fields". Most of them are wrong because of https://github.com/golang/go/issues/9171.	9 years ago
Fabian Reinartz	3a0145c09e	Reenable blocked appending tests	9 years ago
Fabian Reinartz	306e8468a0	Switch from client_golang/model to common/model	9 years ago
Jimmi Dyson	923f8111d4	Initial Kubernetes discovery Fixes #904	9 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).	9 years ago
Jimmi Dyson	da4c50a6cf	Make scheme relabelable via discovery	9 years ago
Jimmi Dyson	52cf6b3e6e	Configuration options for bearer tokens, client certs & CA certs Fixes #918, fixes #917	9 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.	9 years ago
Fabian Reinartz	c292979374	retrieval: double timeout in target scrape test.	10 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.	10 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.	10 years ago
Brian Brazil	58ceae82bc	Revert "Allow ingested metrics to be relabeled." This reverts commit `f2f26ca08f`. Was accidentally pushed to master instead of a branch for PR.	10 years ago

Fabian Reinartz	0de6edbdfc	Move pkg/ to util/	10 years ago
Fabian Reinartz	dfaf31a1da	Move web/httputils to pkg/httputil and add DeadlineClient to it	10 years ago
Fabian Reinartz	8de50619f1	Increase target test wait times On slow systems such as Travis CI occasionally the tests fail because the wait times are too short.	10 years ago
Fabian Reinartz	385919a65a	Avoid inter-component blocking if ingestion/scraping blocks. Appending to the storage can block for a long time. Timing out scrapes can also cause longer blocks. This commit avoids that those blocks affect other compnents than the target itself. Also the Target interface was removed.	10 years ago
Fabian Reinartz	1a2d57b45c	Move template functionality out of target. The target implementation and interface contain methods only serving a specific purpose of the templates. They were moved to the template as they operate on more fundamental target data.	10 years ago
Fabian Reinartz	dbc08d390e	Move target status data into its own object	10 years ago
Fabian Reinartz	93548a8882	Add initial file based service discovery. This commits adds file based service discovery which reads target groups from specified files. It detects changes based on file watches and regular refreshes.	10 years ago
Fabian Reinartz	5fbde88919	Switch config to YAML format.	10 years ago
Fabian Reinartz	0b619b46d6	Change JobConfig to ScrapeConfig. This commit changes the configuration interface from job configs to scrape configs. This includes allowing multiple ways of target definition at once and moving DNS SD to its own config message. DNS SD can now contain multiple DNS names per configured discovery.	10 years ago
Fabian Reinartz	5015c2a0e8	Make target manager source based. This commit shifts responsibility for maintaining targets from providers and pools to the target manager. Target groups have a source name that identifies them for updates.	10 years ago
beorn7	fa1935a644	Remove /api/targets call and do not show job and instance labels on status. /api/targets was undocumented and never used and also broken. Showing instance and job labels on the status page (next to targets) does not make sense as those labels are set in an obvious way. Also add a doc comment to TargetStateToClass.	10 years ago
beorn7	be11cb2b07	Remove the sample ingestion channel. The one central sample ingestion channel has caused a variety of trouble. This commit removes it. Targets and rule evaluation call an Append method directly now. To incorporate multiple storage backends (like OpenTSDB), storage.Tee forks the Append into two different appenders. Note that the tsdb queue manager had its own queue anyway. It was a queue after a queue... Much queue, so overhead... Targets have their own little buffer (implemented as a channel) to avoid stalling during an http scrape. But a new scrape will only be started once the old one is fully ingested. The contraption of three pipelined ingesters was removed. A Target is an ingester itself now. Despite more logic in Target, things should be less confusing now. Also, remove lint and vet warnings in ast.go.	10 years ago
Julius Volz	140eede5e0	Rename UNREACHABLE to UNHEALTHY. The current wording suggests that a target is not reachable at all, although it might also get set when the target was reachable, but there was some other error during the scrape (invalid headers or invalid scrape content). UNHEALTHY is a more general wording that includes all these cases. For consistency, ALIVE is also renamed to HEALTHY.	10 years ago
Sergiusz 'q3k' Bazański	0d0bb3c030	Change instance identifiers to be host:port This changes the PublicURL function into InstanceIdentifier, which now returns a simple <host>:<port> string instead of a full URL.	10 years ago
Sergiusz 'q3k' Bazański	bb69a3d284	Hide HTTP auth parts from URL This instroduces an extra function in the Target interface (PublicURL) which is used to populate the instance field in scraped metrics.	10 years ago
