beorn7	767c0709b1	Retrieval: Avoid copying Target retreival.Target contains a mutex. It was copied in the Targets() call. This potentially can wreak a lot of havoc. It might even have caused the issues reported as #2266 and #2262 .	8 years ago

beorn7	e2b3626e0c	retrieval: Clean up target group map on config reload Also, remove unused `providers` field in targetSet. If the config file changes, we recreate all providers (by calling `providersFromConfig`) and retrieve all targets anew from the newly created providers. From that perspective, it cannot harm to clean up the target group map in the targetSet. Not doing so (as it was the case so far) keeps stale targets around. This mattered if an existing key in the target group map was not overwritten in the initial fetch of all targets from the providers. Examples where that mattered: ``` scrape_configs: - job_name: "foo" static_configs: - targets: ["foo:9090"] - targets: ["bar:9090"] ``` updated to: ``` scrape_configs: - job_name: "foo" static_configs: - targets: ["foo:9090"] ``` `bar:9090` would still be monitored. (The static provider just enumerates the target groups. If the number of target groups decreases, the old ones stay around. ``` scrape_configs: - job_name: "foo" dns_sd_configs: - names: - "srv.name.one.example.org" ``` updated to: ``` scrape_configs: - job_name: "foo" dns_sd_configs: - names: - "srv.name.two.example.org" ``` Now both SRV records are still monitored. The SRV name is part of the key in the target group map, thus the new one is just added and the old ane stays around. Obviously, this should have tests, and should have tests before, not only for this case. This is the quick fix. I have created https://github.com/prometheus/prometheus/issues/1906 to track test creation. Fixes https://github.com/prometheus/prometheus/issues/1610 .	8 years ago

Fabian Reinartz	d0eeae9d0e	retrieval: don't sync to uninitialized scrape pool This change does just signal a scrape target update to the scraping loop once an initial target set is fetched. Before, the scrape pool was directly synced, causing a race against an uninitialized scrape pool. Fixes #1703	9 years ago
Fabian Reinartz	0f21bd31ca	config: deprecate `target_groups` for `static_configs` This change deprecates the `target_groups` option in favor of `static_configs`. The old configuration is still accepted but prints a warning. Configuration loading errors if both options are set.	9 years ago

Fabian Reinartz	56fc9bdff3	Handle closed target provider channel This fixes the case where a target provider closes the update channel and exits before the context is canceled. This should only be true for the static provider but it's safer to generally handle this case.	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	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	05de8b7f8d	Extract target scraping into scrape loop. This commit factors out the scrape loop handling into its own data structure. For the transition it will be directly attached to the target.	9 years ago
Fabian Reinartz	cebba3efbb	Simplify and fix TargetManager reloading	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	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
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

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
Julien Dehee	061fe2f364	Support AirBnB's Smartstack Nerve client for SD nerve's registration format differs from serverset. With this commit there is now a dedicated treecache file in util, and two separate files for serverset and nerve. Reference: https://github.com/airbnb/nerve	9 years ago
Fabian Reinartz	29a69eecb8	Do not panic in Consul SD creation	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.
