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.

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

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	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	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

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
beorn7	5678a86924	Throttle scraping if a scrape took longer than the configured interval. The simple algorithm applied here will increase the actual interval incrementally, whenever and as long as the scrape itself takes longer than the configured interval. Once it takes shorter again, the actual interval will iteratively decrease again.	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

Bjoern Rabenstein	92156ee89d	Drain the newBaseLabels channel upon shutdown. This should help cut down shutdown times. Change-Id: I6e70a598a9e49aa6eeeb2034105b1bc6e9014324	10 years ago
Bjoern Rabenstein	6b37e47f9e	Remove unused metrics. Change-Id: Icf03ba4ce92a5e38daf12930f9661daba79c83bb	10 years ago
Bjoern Rabenstein	4447708c9f	Fix a race in target.go. Also, fix problems in shutdown. Starting serving and shutdown still has to be cleaned up properly. It's a mess. Change-Id: I51061db12064e434066446e6fceac32741c4f84c	10 years ago
Bjoern Rabenstein	e0a6cb281e	Fix the accept header. A '/' is a separator and has to be in a quoted string. Change-Id: If7a3a847f84f8f709074d05dc98b5b21e954030c	10 years ago

Bjoern Rabenstein	1909686789	Make metrics exported by the Prometheus server itself more consistent. - Always spell out the time unit (e.g. milliseconds instead of ms). - Remove "_total" from the names of metrics that are not counters. - Make use of the "Namespace" and "Subsystem" fields in the options. - Removed the "capacity" facet from all metrics about channels/queues. These are all fixed via command line flags and will never change during the runtime of a process. Also, they should not be part of the same metric family. I have added separate metrics for the capacity of queues as convenience. (They will never change and are only set once.) - I left "metric_disk_latency_microseconds" unchanged, although that metric measures the latency of the storage device, even if it is not a spinning disk. "SSD" is read by many as "solid state disk", so it's not too far off. (It should be "solid state drive", of course, but "metric_drive_latency_microseconds" is probably confusing.) - Brian suggested to not mix "failure" and "success" outcome in the same metric family (distinguished by labels). For now, I left it as it is. We are touching some bigger issue here, especially as other parts in the Prometheus ecosystem are following the same principle. We still need to come to terms here and then change things consistently everywhere. Change-Id: If799458b450d18f78500f05990301c12525197d3	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
Julius Volz	1bb7074fec	Fix HTTP connection leak upon non-OK status. Change-Id: Ie7fbd7dcc089b8306b40631be3e3d736c23c1cd3	10 years ago
Bjoern Rabenstein	bacc31d5cc	Remove work-around that required copying all bytes of a scrape. Now that the subtle bug in matttproud/golang_protobuf_extensions is fixed, we do not need to copy the bytes of a scrape into a buffer first before starting to parse it. Change-Id: Ib73ecae16173ddd219cda56388a8f853332f8853	10 years ago
Bjoern Rabenstein	8956faeccb	Migrate to new client_golang. This change will only be submitted when the new client_golang has been moved to the new version. Change-Id: Ifceb59333072a08286a8ac910709a8ba2e3a1581	10 years ago
Bjoern Rabenstein	814e479723	Treat non-200 HTTP response as error. Change-Id: I2a9f3b47012b3c4839be53aa44c66d16dd41a24a	10 years ago

Bjoern Rabenstein	64811caaec	Make Prometheus announce its new super-power: text format! Change-Id: Ia2ddfb28999c145e4d46c395381a9bf89d43148c	11 years ago
Julius Volz	740d448983	Use custom timestamp type for sample timestamps and related code. So far we've been using Go's native time.Time for anything related to sample timestamps. Since the range of time.Time is much bigger than what we need, this has created two problems: - there could be time.Time values which were out of the range/precision of the time type that we persist to disk, therefore causing incorrectly ordered keys. One bug caused by this was: https://github.com/prometheus/prometheus/issues/367 It would be good to use a timestamp type that's more closely aligned with what the underlying storage supports. - sizeof(time.Time) is 192, while Prometheus should be ok with a single 64-bit Unix timestamp (possibly even a 32-bit one). Since we store samples in large numbers, this seriously affects memory usage. Furthermore, copying/working with the data will be faster if it's smaller. MEMORY USAGE RESULTS Initial memory usage comparisons for a running Prometheus with 1 timeseries and 100,000 samples show roughly a 13% decrease in total (VIRT) memory usage. In my tests, this advantage for some reason decreased a bit the more samples the timeseries had (to 5-7% for millions of samples). This I can't fully explain, but perhaps garbage collection issues were involved. WHEN TO USE THE NEW TIMESTAMP TYPE The new clientmodel.Timestamp type should be used whenever time calculations are either directly or indirectly related to sample timestamps. For example: - the timestamp of a sample itself - all kinds of watermarks - anything that may become or is compared to a sample timestamp (like the timestamp passed into Target.Scrape()). When to still use time.Time: - for measuring durations/times not related to sample timestamps, like duration telemetry exporting, timers that indicate how frequently to execute some action, etc. NOTE ON OPERATOR OPTIMIZATION TESTS We don't use operator optimization code anymore, but it still lives in the code as dead code. It still has tests, but I couldn't get all of them to pass with the new timestamp format. I commented out the failing cases for now, but we should probably remove the dead code soon. I just didn't want to do that in the same change as this. Change-Id: I821787414b0debe85c9fffaeb57abd453727af0f	11 years ago

Julius Volz	3b970c5133	Add variable interpolation to notification messages. This includes required refactorings to enable replacing the http client (for testing) and moving the NotificationReq type definitions to the "notifications" package, so that this package doesn't need to depend on "rules" anymore and that it can instead use a representation of the required data which only includes the necessary fields.	11 years ago

Julius Volz	a1ba23038e	Fix scrape timestamps to reduce sample time jitter. We're currently timestamping samples with the time at the end of a scrape iteration. It makes more sense to use a timestamp from the beginning of the scrape for two reasons: a) this time is more relevant to the scraped values than the time at the end of the HTTP-GET + JSON decoding work. b) it reduces sample timestamp jitter if we measure at the beginning, and not at the completion of a scrape.	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
Matt T. Proud	5a9417f80a	Include humanized target state strings. In the current /status implementation, we cannot divine what the target's state is but rather get an integer constant for it. This commit, stringifies the constants.	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	047eb219e4	Fix target health state update. Right now, futureState is only used to give hints to the health scheduler, but nowhere is this future state persisted into the target's state field, so we don't actually track a target's state over time.	12 years ago
Julius Volz	5d55785936	Fix broken target scrape error propagation.	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
