Matt Bostock	329a00e44f	Relabel: Document whole label set is dropped ... From the documentation and current tests, it wasn't immediately clear to me whether the `target` being dropped as the result of a 'drop' action was a label key-value pair or the entire labelset. Add a test that documents this behaviour. Documentation: https://prometheus.io/docs/operating/configuration/	9 years ago

beorn7	45e5775f9b	Add missing logging of out-of-order samples ... So far, out-of-order samples during rule evaluation were not logged, and neither scrape health samples. The latter are unlikely to cause any errors. That's why I'm logging them always now. (It's alway highly irregular should it happen.) For rules, I have used the same plumbing as for samples, just with a different wording in the message to mark them as a result of rule evaluation.	9 years ago

Fabian Reinartz	1ede7b9d72	Consolidate TargetStatus into Target. ... This commit simplifies the TargetHealth type and moves the target status into the target itself. This also removes a race where error and last scrape time could have been out of sync.	9 years ago
Fabian Reinartz	2060a0a15b	Turn target group members into plain lists. ... As the scrape pool deduplicates targets now, it is no longer necessary to store a hash map for members of each group.	9 years ago
Fabian Reinartz	0d7105abee	Remove scrape config from Target. ... This commit removes the scrapeConfig entirely from Target. All identity defining parameters are thus immutable now and the mutex can be removed.. Target identity is now correctly defined by the labels and the full URL. This in particular includes URL parameters that are not specified in the label set. Fingerprint is also removed from hash to remove an unnecessary tight coupling to the common/model package.	9 years ago
Fabian Reinartz	75681b691a	Extract HTTP client from Target. ... The HTTP client is the same across all targets with the same scrape configuration. Thus, this commit moves it into the scrape pool.	9 years ago
Fabian Reinartz	9bea27ae8a	Add scraping tests	9 years ago
Fabian Reinartz	76a8c6160d	Deduplicate targets in scrape pool. ... With this commit the scrape pool deduplicates incoming targets before scraping them. This way multiple target providers can produce the same target but it will be scraped only once.	9 years ago
Fabian Reinartz	84f74b9a84	Apply new scrape config on reload. ... This commit updates a target set's scrape configuration on reload. This will cause all running scrape loops to be stopped and started again with new parameters.	9 years ago

Fabian Reinartz	da99366f85	Consolidate Target.Update into constructor. ... The Target.Update method is no longer needed.	9 years ago
Fabian Reinartz	d15adfc917	Preserve target state across reloads. ... This commit moves Scraper handling into a separate scrapePool type. TargetSets only manage TargetProvider lifecycles and sync the retrieved updates to the scrapePool. TargetProviders are now expected to send a full initial target set within 5 seconds. The scrapePools preserve target state across reloads and only drop targets after the initial set was synced.	9 years ago
Fabian Reinartz	5b30bdb610	Change TargetProvider interface. ... This commit changes the TargetProvider interface to use a context.Context and send lists of TargetGroups, rather than single ones.	9 years ago
Fabian Reinartz	bb6dc3ff78	Remove old tests	9 years ago
Fabian Reinartz	5bfa4cdd46	Simplify target update handling. ... We group providers by their scrape configuration. Each provider produces target groups with an unique identifier. On stopping a set of target providers we cancel the target providers, stop scraping the targets and wait for the scrapers to finish. On configuration reload all provider sets are stopped and new ones are created. This will make targets disappear briefly on configuration reload. Potentially scrapes are missed but due to the consistent scrape intervals implemented recently, the impact is minor.	9 years ago

beorn7	33a50e69f7	Fix a deadlock ... Double acquisition of the RLock usually doesn't blow up, but if the write lock is called for between the two RLock's, we are deadlocked. This deadlock does not exist in release-0.17, BTW.	9 years ago
beorn7	fd5108b038	Fix a targetmanager test	9 years ago
Fabian Reinartz	6df1f49c13	Remove fullLabels method and fix target updating ... With recent changes to a Target's internal data representation updating by fullLabels() assigns the additional default instance label. This breaks target identity comparison and causes identical targets from service discovery to be constantly swapped.	9 years ago
Fabian Reinartz	825831e98f	Use fingerprint for target identity comparison ... So far we were using the InstanceIdentifier to compare equality of targets. This is not always accurate, for example for the blackbox exporter where the actual target is in the parameter.	9 years ago
Fabian Reinartz	66767121ab	Handle scrape timeout on request. ... For historic reasons we were enforcing a timeout directly via the TCP dialer. This is no longer necessary for quite a while now. Switching to context.Context will allow us to properly terminate requests on shutdown as well.	9 years ago
Julius Volz	293486c7b1	Remove old superfluous calls to setLastScrape(). ... This is called from within the scrape()->report() flow now. See https://github.com/prometheus/prometheus/pull/1394/files#r52945817	9 years ago

Fabian Reinartz	fe7e91e2eb	Make scraping offset consistent. ... To evenly distribute scraping load we currently rely on random jittering. This commit hashes over the target's identity and calculates a consistent offset. This also ensures that scrape intervals are constantly spaced between config/target changes.	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
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

Federico Baldo	d14d2429ea	Minor improvements to ec2 sd: ... 1. static credentials replaced with defaults.DefaultChainCredentials. This change ensures that credentials are sourced form all possible providers available with the aws sdk, in the following order: env variables, shared awsconfig file in user folder, ec2 instance role. 2. Added a few labels: AvailabilityZone, PublicDns, VpcId (if available), SubnetId (if in Vpc)	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.
