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

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

Jonathan Boulle	38098f8c95	Add missing license headers Prometheus is Apache 2 licensed, and most source files have the appropriate copyright license header, but some were missing it without apparent reason. Correct that by adding it.	9 years ago

Fabian Reinartz	59f1e722df	Return error on sample appending	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
Corentin Chary	7b6c3e556c	Use '.' instead of '=' to separate labels from their values in Graphite Using .label=value. was weird to use in Graphite and didn't bring much value.	9 years ago
Corentin Chary	a2e4439086	Add support for remote storage on Graphite Allows to use graphite over tcp or udp. Metrics labels and values are used to construct a valid Graphite path in a way that will allow us to eventually read them back and reconstruct the metrics. For example, this metric: model.Metric{ model.MetricNameLabel: "test:metric", "testlabel": "test:value", "testlabel2": "test:value", ) Will become: test:metric.testlabel=test:value.testlabel2=test:value escape.go takes care of escaping values to match Graphite character set, it basically uses percent-encoding as a fallback wich will work pretty will in the graphite/grafana world. The remote storage module also has an optional 'prefix' parameter to prefix all metrics with a path (for example, 'prometheus.'). Graphite URLs are simply in the form tcp://host:port or udp://host:port.	9 years ago

Julius Volz	eeb1da36ac	Fix InfluxDB write support to work with InfluxDB 0.9.x. Because the InfluxDB client library currently pulls in multiple MBs of unnecessary dependencies, I have modified and cut up the vendored version to only pull in the few pieces that are actually needed. On InfluxDB's side, this dependency issue is tracked in: https://github.com/influxdb/influxdb/issues/3447 Hopefully, it will be resolved soon. If a password is needed for InfluxDB, it may be supplied via the INFLUXDB_PW environment variable.	9 years ago

Julius Volz	963ad82dcb	Fix "go vet" errors. I ignored all errors of the type "composite literal uses unkeyed fields". Most of them are wrong because of https://github.com/golang/go/issues/9171.	9 years ago

Will Rouesnel	7810448dbe	Add proxy_url parameter to allow specifying per-job HTTP proxy servers Allow scrape_configs to have an optional proxy_url option which specifies a proxy to be used for all connections to hosts in that config. Internally this modifies the various client functions to take a *url.URL pointer which currently must point to an HTTP proxy (but has been left open-ended to allow the url format to be extended to support others, such as maybe SOCKS if needed).	9 years ago

Julius Volz	267fd34156	Switch Prometheus to use github.com/prometheus/log. This change is conceptually very simple, although the diff is large. It switches logging from "github.com/golang/glog" to "github.com/prometheus/log", while not actually changing any log messages. V(1)-style logging has been changed to be log.Debug*().	10 years ago

Julius Volz	61fb688dd9	Add experimental InfluxDB write support.	10 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

Bjoern Rabenstein	1909686789	Make metrics exported by the Prometheus server itself more consistent. - Always spell out the time unit (e.g. milliseconds instead of ms). - Remove "_total" from the names of metrics that are not counters. - Make use of the "Namespace" and "Subsystem" fields in the options. - Removed the "capacity" facet from all metrics about channels/queues. These are all fixed via command line flags and will never change during the runtime of a process. Also, they should not be part of the same metric family. I have added separate metrics for the capacity of queues as convenience. (They will never change and are only set once.) - I left "metric_disk_latency_microseconds" unchanged, although that metric measures the latency of the storage device, even if it is not a spinning disk. "SSD" is read by many as "solid state disk", so it's not too far off. (It should be "solid state drive", of course, but "metric_drive_latency_microseconds" is probably confusing.) - Brian suggested to not mix "failure" and "success" outcome in the same metric family (distinguished by labels). For now, I left it as it is. We are touching some bigger issue here, especially as other parts in the Prometheus ecosystem are following the same principle. We still need to come to terms here and then change things consistently everywhere. Change-Id: If799458b450d18f78500f05990301c12525197d3	10 years ago
