Fabian Reinartz	59f1e722df	Return error on sample appending	9 years ago
beorn7	ec08c9a391	Rework the way to communicate backpressure (AKA suspended ingestion) This gives up on the idea to communicate throuh the Append() call (by either not returning as it is now or returning an error as suggested/explored elsewhere). Here I have added a Throttled() call, which has the advantage that it can be called before a whole _batch_ of Append()'s. Scrapes will happen completely or not at all. Same for rule group evaluations. That's a highly desired behavior (as discussed elsewhere). The code is even simpler now as the whole ingestion buffer could be removed. Logging of throttled mode has been streamlined and will create at most one message per minute.	9 years ago
Brian Brazil	7a5f019c40	Use up/down in UI for consistency with 'up' metric.	9 years ago
Fabian Reinartz	e3b6ec9784	Switch to common/log	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
Fabian Reinartz	327152862c	Update expfmt.NewDecoder usage	9 years ago
Anders Daljord Morken	9fb65a91af	Close HTTP connections on HTTP errors too. Move defer resp.Body.Close() up to make sure it's called even when the HTTP request returns something other than 200 or Decoder construction fails. This avoids leaking and eventually running out of file descriptors.	9 years ago

Jimmi Dyson	a1574aa2b3	Move TLS options to scrape config Fixes #1013, fixes #989	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

Jimmi Dyson	923f8111d4	Initial Kubernetes discovery Fixes #904	9 years ago
Will Rouesnel	7810448dbe	Add proxy_url parameter to allow specifying per-job HTTP proxy servers Allow scrape_configs to have an optional proxy_url option which specifies a proxy to be used for all connections to hosts in that config. Internally this modifies the various client functions to take a *url.URL pointer which currently must point to an HTTP proxy (but has been left open-ended to allow the url format to be extended to support others, such as maybe SOCKS if needed).	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	d53cc7935d	retrieval: avoid race conditions	10 years ago
Julius Volz	d868264bb8	Improve UI of /alerts page. Changes to the UI: - "Active Since" timestamps are now human-readable. - Alerting rules are now pretty-printed better. - Labels are no longer just strings, but alert bubbles (like we do on the status page for base labels). - Alert states and target health states are now capitalized in the presentation layer rather than at the source.	10 years ago
Fabian Reinartz	53b9d5917d	web: improve target URL handling and display.	10 years ago
Fabian Reinartz	dc7d27ab9a	retrieval: add honor label handling and parametrized querying. This commit adds the honor_labels and params arguments to the scrape config. This allows to specify query parameters used by the scrapers and handling scraped labels with precedence.	10 years ago
Brian Brazil	0dbae36d36	Allow ingested metrics to be relabeled. The main purpose of this is to allow for blacklisting of expensive metrics as a tactical option. It could also find uses for renaming and removing labels from federation.	10 years ago
Brian Brazil	58ceae82bc	Revert "Allow ingested metrics to be relabeled." This reverts commit `f2f26ca08f`. Was accidentally pushed to master instead of a branch for PR.	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	0de6edbdfc	Move pkg/ to util/	10 years ago
Fabian Reinartz	dfaf31a1da	Move web/httputils to pkg/httputil and add DeadlineClient to it	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	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	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	5fbde88919	Switch config to YAML format.	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
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
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
