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

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

Julius Volz	9cea5d9df8	Convert the Prometheus configuration to protocol buffers.	12 years ago
Johannes 'fish' Ziemke	14407a076a	Convert addresses pointing to localhost in status. Until now, targets pointing to localhost in the status view are linked to localhost, so you can't follow those links by clicking on them. This change converts the links to point to the hostname of the prometheus server. Before: <a href="http://localhost:9090/metrics.json">http://localhost:9090/metrics.json</a> After: <a href="http://hostname-of-prometheus-server:9090/metrics.json">http://localhost:9090/metrics.json</a>	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
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
