Julius Volz	e9476b35d5	Re-add multiple remote writers Each remote write endpoint gets its own set of relabeling rules. This is based on the (yet-to-be-merged) https://github.com/prometheus/prometheus/pull/2419, which removes legacy remote write implementations.	8 years ago
Tom Wilkie	4520e12440	Add HTTP Basic Auth & TLS support to the generic write path. (#1957 ) * Add config, HTTP Basic Auth and TLS support to the generic write path. - Move generic write path configuration to the config file - Factor out config.TLSConfig -> tlf.Config translation - Support TLSConfig for generic remote storage - Rename Run to Start, and make it non-blocking. - Dedupe code in httputil for TLS config. - Make remote queue metrics global.	8 years ago

Tom Wilkie	ece12bff93	Shard/parrallelise samples by fingerprint in StorageQueueManager By splitting the single queue into multiple queues and flushing each individual queue in serially (and all queues in parallel), we can guarantee to preserve the order of timestampsin samples sent to downstream systems.	8 years ago

Dan Milstein	007907b410	Fix one of the tests for a remote storage QueueManager Specifically, the TestSpawnNotMoreThanMaxConcurrentSendsGoroutines was failing on a fresh checkout of master. The test had a race condition -- it would only pass if one of the spawned goroutines happened to very quickly pull a set of samples off an internal queue. This patch rewrites the test so that it deterministically waits until all samples have been pulled off that queue. In case of errors, it also now reports on the difference between what it expected and what it found. I verified that, if the code under test is deliberately broken, the test successfully reports on that.	8 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	61d26e8445	Add optional sample replication to OpenTSDB. Prometheus needs long-term storage. Since we don't have enough resources to build our own timeseries storage from scratch ontop of Riak, Cassandra or a similar distributed datastore at the moment, we're planning on using OpenTSDB as long-term storage for Prometheus. It's data model is roughly compatible with that of Prometheus, with some caveats. As a first step, this adds write-only replication from Prometheus to OpenTSDB, with the following things worth noting: 1) I tried to keep the integration lightweight, meaning that anything related to OpenTSDB is isolated to its own package and only main knows about it (essentially it tees all samples to both the existing storage and TSDB). It's not touching the existing TieredStorage at all to avoid more complexity in that area. This might change in the future, especially if we decide to implement a read path for OpenTSDB through Prometheus as well. 2) Backpressure while sending to OpenTSDB is handled by simply dropping samples on the floor when the in-memory queue of samples destined for OpenTSDB runs full. Prometheus also only attempts to send samples once, rather than implementing a complex retry algorithm. Thus, replication to OpenTSDB is best-effort for now. If needed, this may be extended in the future. 3) Samples are sent in batches of limited size to OpenTSDB. The optimal batch size, timeout parameters, etc. may need to be adjusted in the future. 4) OpenTSDB has different rules for legal characters in tag (label) values. While Prometheus allows any characters in label values, OpenTSDB limits them to a to z, A to Z, 0 to 9, -, _, . and /. Currently any illegal characters in Prometheus label values are simply replaced by an underscore. Especially when integrating OpenTSDB with the read path in Prometheus, we'll need to reconsider this: either we'll need to introduce the same limitations for Prometheus labels or escape/encode illegal characters in OpenTSDB in such a way that they are fully decodable again when reading through Prometheus, so that corresponding timeseries in both systems match in their labelsets.
