Fabian Reinartz	d19d1bcad3	discovery: move into top-level package	8 years ago
Fabian Reinartz	7bd9508c9b	discovery: move TargetProvider and multi-constructor	8 years ago
Dan Milstein	0cb6b9962e	Fix broken test which relied on DNS resolution #1962 Switched to testing by way of the static_configs rather than dns_sd_config parameter. Verified that the revised test both passes without network access, and also still catches the bug it's supposed to cover.	8 years ago
Fabian Reinartz	17cdd4f966	retrieval: fix IPv6 port default, add tests This fixes port defaulting for IPv6 addresses and restructures and test the construction of target label sets.	8 years ago
Dan Milstein	b9fb9742ed	Move test helper function into scope of test func	8 years ago
Dan Milstein	79216011cb	Add basic test for TargetManager.targetSet Verify that if the configs change, target groups are cleaned on TargetManager.reload (rather than having old ones linger around, even if they are no longer present in the configs). This covers the bug fixed in #1907 -- I verified that by checking out source from before that commit. This is a start on #1906	8 years ago

beorn7	fd5108b038	Fix a targetmanager test	9 years ago
Fabian Reinartz	a06bc75519	Remove occurrences of 'base' labels	9 years ago
Fabian Reinartz	0d44248fb8	Cleanup cluttered test data	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	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
Brian Brazil	b03569267e	retrieval: Add URL parameters to fullLabels too Move all the special cases into one map, rather than spreading the logic around.	9 years ago
Brian Brazil	4bc39dc60e	retrieval: Reduce flakiness of TestTargetManagerChan This will increase test time by a few hundred ms, this is the 2nd most common cause of flakiness.	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
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	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	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
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	0af1cff8af	config: simplify default config handling.	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
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	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	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	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
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
Johannes 'fish' Ziemke	ff95a52b0f	Rename Address to URL The "Address" is actually a URL which may contain username and password. Calling this Address is misleading so we rename it. Change-Id: I441c7ab9dfa2ceedc67cde7a47e6843a65f60511	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	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
Brian Brazil	4a2b96f848	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
Bjoern Rabenstein	ca6a4fccef	Weed out our homegrown test.Tester. The Go stdlib has testing.TB now, which fulfills the exact same purpose. Change-Id: I0db9c73400e208ca376b932a02b7e3402234b87c	11 years ago
Julius Volz	d69b85e6c9	Add global label support via Ingesters.	11 years ago
Julius Volz	81f0b85013	Return [] instead of null for empty result vectors.	12 years ago
Julius Volz	331be19af6	Fix broken retrieval tests. These have been broken since `06b4a40661`	12 years ago
Matt T. Proud	06b4a40661	Represent targets in a tabular interface. This commit represents a target group's endpoints in a tabular fashion for better differentiation of their state in a concise manner.	12 years ago
