Julius Volz	f7e8348a88	Re-add contexts to storage.Storage.Querier() (#3230 ) * Re-add contexts to storage.Storage.Querier() These are needed when replacing the storage by a multi-tenant implementation where the tenant is stored in the context. The 1.x query interfaces already had contexts, but they got lost in 2.x. * Convert promql.Engine to use native contexts	7 years ago

Tom Wilkie	ec999ff397	Prevent number of remote write shards from going negative. This can happen in the situation where the system scales up the number of shards massively (to deal with some backlog), then scales it down again as the number of samples sent during the time period is less than the number received.	7 years ago

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
Julius Volz	beb3c4b389	Remove legacy remote storage implementations This removes legacy support for specific remote storage systems in favor of only offering the generic remote write protocol. An example bridge application that translates from the generic protocol to each of those legacy backends is still provided at: documentation/examples/remote_storage/remote_storage_bridge See also https://github.com/prometheus/prometheus/issues/10 The next step in the plan is to re-add support for multiple remote storages.	8 years ago
Brian Brazil	1b8a474612	Don't clone the metric if there's no remote writes. The metric clone can't be further optimised, and is a non-trivial memory allocation cost so fast path it if there's no remote writes configured.	8 years ago
Julius Volz	c7932aa009	Remove gRPC leftovers in protobuf definitions	8 years ago
Brian Brazil	77605649a9	Add support for remote write relabelling. Switch back to a single remote writer, as we were only ever meant to have one and the relabel semantics are clearer that way.	8 years ago
Matthew Campbell	67d76e3a5d	timeseries: store varbit encoded data into cassandra	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	d83879210c	Switch back to protos over HTTP, instead of GRPC. My aim is to support the new grpc generic write path in Frankenstein. On the surface this seems easy - however I've hit a number of problems that make me think it might be better to not use grpc just yet. The explanation of the problems requires a little background. At weave, traffic to frankenstein need to go through a couple of services first, for SSL and to be authenticated. So traffic goes: internet -> frontend -> authfe -> frankenstein - The frontend is Nginx, and adds/removes SSL. Its done this way for legacy reasons, so the certs can be managed in one place, although eventually we imagine we'll merge it with authfe. All traffic from frontend is sent to authfe. - Authfe checks the auth tokens / cookie etc and then picks the service to forward the RPC to. - Frankenstein accepts the reads and does the right thing with them. First problem I hit was Nginx won't proxy http2 requests - it can accept them, but all calls downstream are http1 (see https://trac.nginx.org/nginx/ticket/923). This wasn't such a big deal, so it now looks like: internet --(grpc/http2)--> frontend --(grpc/http1)--> authfe --(grpc/http1)--> frankenstein Next problem was golang grpc server won't accept http1 requests (see https://groups.google.com/forum/#!topic/grpc-io/JnjCYGPMUms). It is possible to link a grpc server in with a normal go http mux, as long as the mux server is serving over SSL, as the golang http client & server won't do http2 over anything other than an SSL connection. This would require making all our service to service comms SSL. So I had a go a writing a grpc http1 server, and got pretty far. But is was a bit of a mess. So finally I thought I'd make a separate grpc frontend for this, running in parallel with the frontend/authfe combo on a different port - and first up I'd need a grpc reverse proxy. Ideally we'd have some nice, generic reverse proxy that only knew about a map from service names -> downstream service, and didn't need to decode & re-encode every request as it went through. It seems like this can't be done with golang's grpc library - see https://github.com/mwitkow/grpc-proxy/issues/1. And then I was surprised to find you can't do grpc from browsers! See http://www.grpc.io/faq/ - not important to us, but I'm starting to question why we decided to use grpc in the first place? It would seem we could have most of the benefits of grpc with protos over HTTP, and this wouldn't preclude moving to grpc when its a bit more mature? In fact, the grcp FAQ even admits as much: > Why is gRPC better than any binary blob over HTTP/2? > This is largely what gRPC is on the wire.	8 years ago

Tom Wilkie	a6931b71e8	Rationalise retrieval metrics so we have the state (success/failed) on both samples and batches, in a consistent fashion. Also, report total queue capacity of all queues, i.e. capacity * shards.	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
Julius Volz	aa3f2b7216	Generic write cleanups and changes. - fold metric name into labels - return initialization errors back to main - add snappy compression - better context handling - pre-allocation of labels - remove generic naming - other cleanups	8 years ago
Brian Brazil	36d2c4bd0b	Add generic write path using grpc. This uses a new proto format, with scope for multiple samples per timeseries in future. This will allow users to pump samples out to whatever they like without having to change the core Prometheus code. There's also an example receiver to save users figuring out the boilerplate themselves.	8 years ago
Dan Milstein	764ceaa939	Add timeout to test, cap waiting at 1 second	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
