Brian Brazil	f34de493d5	Add increase() function, to replace delta(..., 1). This calculates how much a counter increases over a given period of time, which is the area under the curve of it's rate. increase(x[5m]) is equivilent to rate(x[5m]) * 300.	10 years ago
Julius Volz	267fd34156	Switch Prometheus to use github.com/prometheus/log. This change is conceptually very simple, although the diff is large. It switches logging from "github.com/golang/glog" to "github.com/prometheus/log", while not actually changing any log messages. V(1)-style logging has been changed to be log.Debug*().	10 years ago
Fabian Reinartz	b0c181dc0d	Add Consul SD configuration.	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	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	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
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
Brian Brazil	e56786b221	Have scrape time as a pseudovariable, not a prometheus variable. This ensures it has the right timestamp, and is easier to work with. Switch sd variable away from 'outcome', using total/failed instead.	10 years ago
Bjoern Rabenstein	b1e4956142	Apply a giant code cleanup. Essentially: - Remove unused code. - Make it 'go vet' clean. The only remaining warnings are in generated code. - Make it 'golint' clean. The only remaining warnings are in gerenated code. - Smoothed out same minor things. Change-Id: I3fe5c1fbead27b0e7a9c247fee2f5a45bc2d42c6	10 years ago
Bjoern Rabenstein	fee88a7a77	Remove the remaining races, new and old. Also, resolve a few other TODOs. Change-Id: Icb39b5a5e8ca22ebcb48771cd8951c5d9e112691	10 years ago
Bjoern Rabenstein	74c143c4c9	Improve scraper shutdown time. - Stop target pools in parallel. - Stop individual scrapers in goroutines, too. - Timing tweaks. Change-Id: I9dff1ee18616694f14b04408eaf1625d0f989696	10 years ago
Bjoern Rabenstein	b3ed9aa7a2	Clean up start-up and shut-down. Change-Id: Idff4bbb0a15a9f879bfbb3da5b1025179cab5e2c	10 years ago
Brian Brazil	5edf689133	Stagger scrapes to spread out load. Change-Id: Ib141b271e4adfb817886871f86051c207b05cf35	10 years ago
Julius Volz	fb44580110	Cleanup/fix program termination sequence. Change-Id: I2bc58a2583fb079c9ef383cfc7a5e0fbe613f1cd	11 years ago
Julius Volz	788587426b	Make scrape timeouts configurable per job. Change-Id: I77a7514ad9e7969771f873d63d6353ec50082a62	11 years ago
Julius Volz	d69b85e6c9	Add global label support via Ingesters.	11 years ago
Julius Volz	aa5d251f8d	Use github.com/golang/glog for all logging.	11 years ago
Matt T. Proud	30b1cf80b5	WIP - Snapshot of Moving to Client Model.	12 years ago
Julius Volz	d9b4f98b44	Integrate DNS-SD support for discovering job targets.	12 years ago
Julius Volz	1fe3d3b06b	Remove obsolete argument from target handling code.	12 years ago
Matt T. Proud	8f4c7ece92	Destroy naked returns in half of corpus. The use of naked return values is frowned upon. This is the first of two bulk updates to remove them.	12 years ago
Julius Volz	9cea5d9df8	Convert the Prometheus configuration to protocol buffers.	12 years ago
Julius Volz	a0d311c9e6	Constantize job name label.	12 years ago
Julius Volz	f1fc7d717a	Allow replacing job targets via HTTP API. This roughly comprises the following changes: - index target pools by job instead of scrape interval - make targets within a pool exchangable while preserving existing health state for targets - allow exchanging targets via HTTP API (PUT) - show target lists in /status (experimental, for own debug use)	12 years ago
Julius Volz	c8761f3468	Correct order of deadline and interval arguments.	12 years ago
Matt T. Proud	ea54751431	Update import paths to new location. This repository moved from matttproud/prometheus to prometheus/prometheus, and all import paths need to be updated.	12 years ago
Matt T. Proud	f2ded515b7	Support versioned telemetry providers. client_golang was updated to support full label-oriented telemetry, which introduced interface incompatibilities with the previous version of Prometheus. To alleviate this, a general fetching and processing dispatching system has been created, which discriminates and processes according to the version of input.	12 years ago
Matt T. Proud	190e4e3fa3	``TargetManager`` and ``TargetPool`` ass pointers.	12 years ago
Matt T. Proud	9752f1e61d	Refactor Target as interface for testability. Future tests around the ``TargetPool`` and ``TargetManager`` and friends will be a lot easier when the concrete behaviors of ``Target`` can be extracted out. Plus, each ``Target``, I suspect, will have its own resolution and query strategy.	12 years ago
Matt T. Proud	efe61c18fa	Refactor target scheduling to separate facility. ``Target`` will be refactored down the road to support various nuanced endpoint types. Thusly incorporating the scheduling behavior within it will be problematic. To that end, the scheduling behavior has been moved into a separate assistance type to improve conciseness and testability. ``make format`` was also run.	12 years ago
Julius Volz	56384bf42a	Add initial config and rule language implementation.	12 years ago
Matt T. Proud	2922def8d0	Use the ``TargetManager`` for targets.	12 years ago
