Julien Pivotto	9d9bc524e5	Add query log (#6520 ) * Add query log, make stats logged in JSON like in the API Signed-off-by: Julien Pivotto <roidelapluie@inuits.eu>	5 years ago
gotjosh	e1f2da74a3	api: provide metadata for a single metric This adds support for a new query param on the new `api/v1/metadata` endpoint that provides metadata for a specified metric via the V1 API. It collapses metadata that is equal across all targets, and aggregates under the same metric name the ones that differ. Signed-off-by: gotjosh <josue@grafana.com>	5 years ago

gotjosh	0a0a228db3	api: provide per metric metadata (#6420 ) * api: provide per metric metadata This adds a new endpoint that provides per metric metadata via the V1 API. It collapses metadata that is equal across all targets, and aggregates under the same metric name the ones that differ. * Allow tests to be asserted on response length Some tests e.g. limit on API responses, don't require an assertion on equality. This allows us to assert against response length instead of equality. Signed-off-by: gotjosh <josue@grafana.com>	5 years ago

gotjosh	7bb73a9abd	fix: flaky test for api/v1/targets/metadata. (#6436 ) * Allows sorting of responses from the API in tests Fixes flaky test for api/v1/targets/metadata. Allows sorting of responses from the API. For our tests to be deterministic, we need to ensure the response from the API follows an order. This structure allows us to define one.

gotjosh	428089f83f	api: tests for /target/metadata API endpoint This commit introduces several test cases for the current /targets/metadata API endpoint. To achieve so, we use a mock of the metadataStore and inject it to the targets under test. Currently, three success cases are covered: with a metric name, with a target matcher, and with both. As for the failure scenario, the one where we couldn't match against a particular metric is covered. Signed-off-by: gotjosh <josue@grafana.com>	5 years ago
gotjosh	4bf9c6bb82	Allow targets to be injected as arguments when creating a testTargetRetriever Previously, the struct `testTargetRetriever` had hardcoded active and dropped targets. This made it difficult to change the target information depending on the test case. This change introduces a way to define them as arguments and pass it to a constructor for building. It lays a foundation for dynamically defining targets with various set of arguments to test different scenarios. Signed-off-by: gotjosh <josue@grafana.com>	5 years ago

Callum Styan	6f69e31398	Tail the TSDB WAL for remote_write This change switches the remote_write API to use the TSDB WAL. This should reduce memory usage and prevent sample loss when the remote end point is down. We use the new LiveReader from TSDB to tail WAL segments. Logic for finding the tracking segment is included in this PR. The WAL is tailed once for each remote_write endpoint specified. Reading from the segment is based on a ticker rather than relying on fsnotify write events, which were found to be complicated and unreliable in early prototypes. Enqueuing a sample for sending via remote_write can now block, to provide back pressure. Queues are still required to acheive parallelism and batching. We have updated the queue config based on new defaults for queue capacity and pending samples values - much smaller values are now possible. The remote_write resharding code has been updated to prevent deadlocks, and extra tests have been added for these cases. As part of this change, we attempt to guarantee that samples are not lost; however this initial version doesn't guarantee this across Prometheus restarts or non-retryable errors from the remote end (eg 400s). This changes also includes the following optimisations: - only marshal the proto request once, not once per retry - maintain a single copy of the labels for given series to reduce GC pressure Other minor tweaks: - only reshard if we've also successfully sent recently - add pending samples, latest sent timestamp, WAL events processed metrics Co-authored-by: Chris Marchbanks <csmarchbanks.com> (initial prototype) Co-authored-by: Tom Wilkie <tom.wilkie@gmail.com> (sharding changes) Signed-off-by: Callum Styan <callumstyan@gmail.com>	6 years ago

Krasi Georgiev	47a673c3a0	process scrape loops reloading in parallel (#4526 ) The scrape manage receiver's channel now just saves the target sets and another backgorund runner updates the scrape loops every 5 seconds. This is so that the scrape manager doesn't block the receiving channel when it does the long background reloading of the scrape loops. Active and dropped targets are now saved in each scrape pool instead of the scrape manager. This is mainly to avoid races when getting the targets via the web api. When reloading the scrape loops now happens in parallel to speed up the final disared state and this also speeds up the prometheus's shutting down. Also updated some funcs signatures in the web package for consistency. Signed-off-by: Krasi Georgiev <kgeorgie@redhat.com>	6 years ago

Bplotka	1823ae8bc4	Fixed int64 overflow for timestamp in v1/api parseDuration and parseTime (#2501 ) * Fixed int64 overflow for timestamp in v1/api parseDuration and parseTime This led to unexpected results on wrong query with "(...)&start=148966367200.372&end=1489667272.372" That query is wrong because of `start > end` but actually internal int64 overflow caused start to be something around MinInt64 (huge negative value) and was passing validation. BTW: Not sure if negative timestamp makes sense even.. But model.Earliest is actually MinInt64, can someone explain me why?

Julius Volz	c187308366	storage: Contextify storage interfaces. This is based on https://github.com/prometheus/prometheus/pull/1997. This adds contexts to the relevant Storage methods and already passes PromQL's new per-query context into the storage's query methods. The immediate motivation supporting multi-tenancy in Frankenstein, but this could also be used by Prometheus's normal local storage to support cancellations and timeouts at some point.	8 years ago
Julius Volz	ed5a0f0abe	promql: Allow per-query contexts. For Weaveworks' Frankenstein, we need to support multitenancy. In Frankenstein, we initially solved this without modifying the promql package at all: we constructed a new promql.Engine for every query and injected a storage implementation into that engine which would be primed to only collect data for a given user. This is problematic to upstream, however. Prometheus assumes that there is only one engine: the query concurrency gate is part of the engine, and the engine contains one central cancellable context to shut down all queries. Also, creating a new engine for every query seems like overkill. Thus, we want to be able to pass per-query contexts into a single engine. This change gets rid of the promql.Engine's built-in base context and allows passing in a per-query context instead. Central cancellation of all queries is still possible by deriving all passed-in contexts from one central one, but this is now the responsibility of the caller. The central query context is now created in main() and passed into the relevant components (web handler / API, rule manager). In a next step, the per-query context would have to be passed to the storage implementation, so that the storage can implement multi-tenancy or other features based on the contextual information.	8 years ago
