Julius Volz	ab80ced756	storage: separate chunk package, publish more names ... This is a followup to https://github.com/prometheus/prometheus/pull/2011. This publishes more of the methods and other names of the chunk code and moves the chunk code to its own package. There's some unavoidable ugliness: the chunk and chunkDesc metrics are used by both packages, so I had to move them to the chunk package. That isn't great, but I don't see how to do it better without a larger redesign of everything. Same for the evict requests and some other types.	8 years ago

(#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
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

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

Julius Volz	b24e5d63bc	Add noop local storage engine. ... This adds a flag -storage.local.engine which allows turning off local storage in Prometheus. Instead of adding if-conditions and nil checks to all parts of Prometheus that deal with Prometheus's local storage (including the web interface), disabling local storage simply means replacing the normal local storage with a noop version that throws samples away and returns empty query results. We also don't add the noop storage to the fanout appender to decrease internal overhead. Instead of returning empty results, an alternate behavior could be to return errors on any query that point out that the local storage is disabled. Not sure which one is more preferable, so I went with the empty result option for now.	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

beorn7	25385aafcb	Explicitly add logging flags to our custom flag set ... In https://github.com/prometheus/prometheus/pull/1782 , we moved to a custom flag set to avoid getting test flags into the main prometheus binary. However, that removed the logging flags, too. This commit updates the vendoring to a version of the log package that allows adding the log flags to our flag set explicitly.	8 years ago

Fabian Reinartz	9baf120cd5	notifier: dispatch to multiple Alertmanagers ... This commit extends the notifier to dispatch alert batches to multiple Alertmanagers concurrently. It changes the `-alertmanager.url` flag to accept a comma separated list of URLs and/or to be set multiple times.	9 years ago
beorn7	99881ded63	Make the number of fingerprint mutexes configurable ... With a lot of series accessed in a short timeframe (by a query, a large scrape, checkpointing, ...), there is actually quite a significant amount of lock contention if something similar is running at the same time. In those cases, the number of locks needs to be increased. On the same front, as our fingerprints don't have a lot of entropy, I introduced some additional shuffling. With the current state, anly changes in the least singificant bits of a FP would matter.	9 years ago
beorn7	da8cb10b43	Partition the status tab into items in a dropdown ... I got feedback from different sources about rules and targets being too heavy in the status tab if their are lots of them. This change also allows for more fine-granular locking.	9 years ago

beorn7	865d16f870	Rename Gorilla into varbit	9 years ago
beorn7	8cdced3850	Implement Gorilla-inspired chunk encoding ... This is not a verbatim implementation of the Gorilla encoding. First of all, it could not, even if we wanted, because Prometheus has a different chunking model (constant size, not constant time). Second, this adds a number of changes that improve the encoding in general or at least for the specific use case of Prometheus (and are partially only possible in the context of Prometheus). See comments in the code for details.	9 years ago

beorn7	f193f2b8ef	Add a command to promtool that dumps metadata of heads.db ... I needed this today for debugging. It can certainly be improved, but it's already quite helpful. I refactored the reading of heads.db files out of persistence, which is an improvement, too. I made minor changes to the cli package to allow outputting via the io.Writer interface.	9 years ago
