Fabian Reinartz	29a69eecb8	Do not panic in Consul SD creation	9 years ago
Brian Brazil	427bf29db1	Add in default port after relabelling. For the SNMP and blackbox exporters where the ports tends to not be 80/443 and indeed there may not be a port this makes the relabelling a bit simpler as you don't have to figure out this logic exists and strip off the :80. This is a breaking change for the example configs of those exporters.	9 years ago
Brian Brazil	fd2bd81cd8	Allow all instance labels in target groups With the blackbox exporter, the instance label will commonly be used for things other than hostnames so remove this restriction. https://example.com or https://example.com/probe/me are some examples. To prevent user error, check that urls aren't provided as targets when there's no relabelling that could potentically fix them.	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. Fixes https://github.com/prometheus/prometheus/issues/1083	9 years ago
Matt Jibson	dcb4856d72	Add SD for Amazon EC2 instances	9 years ago
Fabian Reinartz	e3b6ec9784	Switch to common/log	9 years ago
Julius Volz	99e8fff872	Fix target manager CPU busyloop caused by bad done-channel handling. Unfortunately this isn't nicely testable, as it's timing-dependent and one would have to detect a stray goroutine doing a CPU busyloop... Fixes https://github.com/prometheus/prometheus/issues/1114	9 years ago
Fabian Reinartz	cc1a2a2061	Remove attachment of global labels upon ingestion	9 years ago
Fabian Reinartz	ebf417a282	Fix map initialization	9 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.	9 years ago
Julius Volz	d36a7f4e6f	Fix busylooping in case of no target providers. merge() closes the channel that handleUpdates() reads from when there are zero configured target providers in the configuration. In that case, the for-select loop in handleUpdates() entered a busy loop. It should exit when the upstream channel is closed.	9 years ago
Fabian Reinartz	438e232c9b	Fix grouping of import blocks	9 years ago
Fabian Reinartz	306e8468a0	Switch from client_golang/model to common/model	9 years ago
Fabian Reinartz	f592740bac	Only exit static target provider on done	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	625374ee36	Clarify docs of TargetProvider	9 years ago
Jimmi Dyson	923f8111d4	Initial Kubernetes discovery Fixes #904	9 years ago
Fabian Reinartz	0138d37458	Improve unique target group sources. Include position of same SD mechanisms within the same scrape configuration. Move unique prefixing out of SD implementations and target manager into its own interface.	9 years ago
Fabian Reinartz	54202bc5a8	Merge pull request #902 from xperimental/feature/marathon-discovery retrieval/discovery: Service discovery using marathon API	9 years ago
Robert Jacob	4d0f974c42	Add service discovery using Marathon API.	9 years ago
Jimmi Dyson	da4c50a6cf	Make scheme relabelable via discovery	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
Brian Brazil	4d895242f9	Add support for Zookeeper Serversets for SD. It can discover an entire tree of serversets, or just one.	10 years ago
Brian Brazil	b8b1d3cbac	Web: Add pre-relabel labels to status page. Figuring out what's going on with the new service discovery and labels is difficult. Add a popover with the labels to the target table to make things simpler, and help discovery of potentially useful labels.	10 years ago
Fabian Reinartz	280d11dca8	main: exit on invalid rule files on startup.	10 years ago
Fabian Reinartz	8b7e5f9184	Stop holding TargetManager lock when stopping components. TargetProviders may flush some last changes to the target manager before actually stopping. To properly read those form the channel the target manager must not be locked while stopping a provider.	10 years ago
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
