Fabian Reinartz	7143dff02f	Add initial implementation for SD via Consul. This commit adds service discovery using Consul's HTTP API and watches (long polling) to retrieve target updates.	10 years ago
Fabian Reinartz	b0c181dc0d	Add Consul SD configuration.	10 years ago
Fabian Reinartz	ff832d2e03	Attach __meta_filepath label to file SD targets.	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	9ca47869ed	Provide full SD configs to discovery constructors. Some SD configs may have many options. To be readable and consistent, make all discovery constructors receive the full config rather than the separate arguments.	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	d5aa012fd0	Make HTTP basic auth configurable for scrape targets.	10 years ago
Fabian Reinartz	bb540fd9fd	Implement config reloading on SIGHUP. With this commit, sending SIGHUP to the Prometheus process will reload and apply the configuration file. The different components attempt to handle failing changes gracefully.	10 years ago
Fabian Reinartz	86087120dd	Replace example config with new YAML format.	10 years ago
Fabian Reinartz	5fbde88919	Switch config to YAML format.	10 years ago
Fabian Reinartz	b5a8f7b8fa	Cleanup, test, and document config.	10 years ago
Fabian Reinartz	945c49a2dd	Add relabelling to target management. This commit adds a relabelling stage on the set of base labels from which a target is created. It allows to drop targets and rewrite any regular or internal label.	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
Fabian Reinartz	4f8673aa88	Simplify update sync for targets, format config fixtures.	10 years ago
Fabian Reinartz	36184f3530	Show correct error on wrong DNS response.	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
Julius Volz	af627bb2b9	Copy vendored deps manually instead of using Godeps. We were using Godep incorrectly (cloning repos from the internet during build time instead of including Godeps/_workspace in the GOPATH via "godep go"). However, to avoid even having to fetch "godeps" from the internet during build, this now just copies the vendored files into the GOPATH. Also, the protocol buffer library moved from Google Code to GitHub, which is reflected in these updates. This fixes https://github.com/prometheus/prometheus/issues/525	10 years ago
beorn7	11b3c2387c	Improvements after review. - Increase samplesQueueCapacity. - Improve docstring for the above. - Accept a short waiting period for the ingest channel to become ready. This should depend on the http timeout, but 100ms is probably good enough to cushion bursts bigger than samplesQueueCapacity, while it is unlikely that anybody ever will set an HTTP timeout similarly short.	10 years ago
beorn7	0f191629c6	Next try to deal with backed-up ingestion. This is now not even trying to throttle in a benign way, but creates a fully-fledged error. Advantage: It shows up very visible on the status page. Disadvantage: The server does not really adjusts to a lower scraping rate. However, if your ingestion backs up, you are in a very irregulare state, I'd say it _should_ be considered an error and not dealt with in a more graceful way. In different news: I'll work on optimizing ingestion so that we will not as easily run into that situation in the first place.	10 years ago
beorn7	16a1a6d324	Add another check for stopped scraper.	10 years ago
beorn7	5678a86924	Throttle scraping if a scrape took longer than the configured interval. The simple algorithm applied here will increase the actual interval incrementally, whenever and as long as the scrape itself takes longer than the configured interval. Once it takes shorter again, the actual interval will iteratively decrease again.	10 years ago
