Chris Marchbanks a6a55c433c Improve desired shards calculation (#5763)
The desired shards calculation now properly keeps track of the rate of
pending samples, and uses the previously unused integralAccumulator to
adjust for missing information in the desired shards calculation.

Also, configure more capacity for each shard.  The default 10 capacity
causes shards to block on each other while
sending remote requests. Default to a 500 sample capacity and explain in
the documentation that having more capacity will help throughput.

* Cache a buffer in each shard for snappy to use

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

Daniele Sluijters f25a6baedb remote: Set User-Agent header in requests (#4891)
Currently Prometheus requests show up with a UA of Go-http-client/1.1
which isn't super helpful. Though the X-Prometheus-Remote-* headers
exist they need to be explicitly configured when logging the request in
order to be able to deduce this is a request originating from

default server logs just a bit more useful.

This also updates a few other places to consistently capitalize the 'P'
in the user agent, as well as ensure we set a UA to begin with.

```

When remove read is enabled, federation will call `q.Select(nil, mset...)`
which will break remote reads because it currently doesn't handle empty
SelectParams.

Fix remote read labelset corruption (#3456)
The labelsets returned from remote read are mutated in higher levels
(like seriesFilter.Labels()) and since the concreteSeriesSet didn't
return a copy, the external mutation affected the labelset in the
concreteSeries itself. This resulted in bizarre bugs where local and
remote series would show with identical label sets in the UI, but not be
deduplicated, since internally, a series might come to look like:

{__name__="node_load5", instance="192.168.1.202:12090", job="node_exporter", node="odroid", node="odroid"}

(note the repetition of the last label)

Thibault Chataigner bf4a279a91 Remote storage reads based on oldest timestamp in primary storage (#3129)
Currently all read queries are simply pushed to remote read clients.
This is fine, except for remote storage for wich it unefficient and
make query slower even if remote read is unnecessary.
So we need instead to compare the oldest timestamp in primary/local
storage with the query range lower boundary. If the oldest timestamp
is older than the mint parameter, then there is no need for remote read.
This is an optionnal behavior per remote read client.

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.

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.

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.

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.

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.

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.

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.

Dan Milstein 764ceaa939 Add timeout to test, cap waiting at 1 second 2016-08-24 11:30:38 -04:00
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.

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.

2016-01-11 13:57:14 +01:00
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.

allow the url format to be extended to support others, such as maybe SOCKS if
needed).
