Fabian Reinartz	d0d2c38c68	Fix tests for append API changes	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
Julius Volz	d88aea7e6f	Fix SD mechanism source prefix handling. The prefixed target provider changed a pointerized target group that was reused in the wrapped target provider, causing an ever-increasing chain of source prefixes in target groups from the Consul target provider. We now make this bug generally impossible by switching the target group channel from pointer to value type and thus ensuring that target groups are copied before being passed on to other parts of the system. I tried to not let the depointerization leak too far outside of the channel handling (both upstream and downstream) because I tried that initially and caused some nasty bugs, which I want to minimize.

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
Fabian Reinartz	306e8468a0	Switch from client_golang/model to common/model	9 years ago
Fabian Reinartz	4e84b86510	Improve target discovery pipeline Replace the TargetProvider Stop method with done channels that ensure properly broadcasted shutdown of the whole pipeline.	9 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
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	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
Bjoern Rabenstein	5859b74f1b	Clean up license issues. - Move CONTRIBUTORS.md to the more common AUTHORS. - Added the required NOTICE file. - Changed "Prometheus Team" to "The Prometheus Authors". - Reverted the erroneous changes to the Apache License.	10 years ago
Julius Volz	d6b9e97655	Remove extraction.Result type, simplify code.	10 years ago
Brian Brazil	3835b7507d	Remove backoff on scrape failure. Having metrics with variable timestamps inconsistently spaced when things fail will make it harder to write correct rules. Update status page, requires some refactoring to insert a function. Change-Id: Ie1c586cca53b8f3b318af8c21c418873063738a8	10 years ago
Julius Volz	d69b85e6c9	Add global label support via Ingesters.	11 years ago
Bernerd Schaefer	428d91c86f	Rename test helper files to helpers_test.go This ensures that these files are properly included only in testing.	12 years ago
