Julius Volz b5163351bf Simplify and fix remote write example 
After removing gRPC, this can be simplified again. Also, the
configuration for the remote storage moved from flags to the config
file.

Maxim Ivanov e6db9f8159 New fpsForLabelMatchers and seriesForLabelMatchers methods 
These more specific methods have replaced `metricForLabelMatchers`
in cases where its  `map[fingerprint]metric` result type was
not necessary or was used as an intermediate step

Avoids duplicated calls to `seriesForRange` from
`QueryRange` and `QueryInstant` methods.

Switch back to a single remote writer, as we were only ever meant to
have one and the relabel semantics are clearer that way.

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.

Matt Bostock 926a5ab3dd rules/manager.go: Fix race between reload and stop 
On one relatively large Prometheus instance (1.7M series), I noticed
that upgrades were frequently resulting in Prometheus undergoing crash
recovery on start-up.

On closer examination, I found that Prometheus was panicking on
shutdown.

It seems that our configuration management (or misconfiguration thereof)
is reloading Prometheus then immediately restarting it, which I suspect
is causing this race:

 2016-09-19 16:31:12 +02:00
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.
 2016-09-19 16:29:07 +02:00
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.

Avoid having contended mutexes on same cacheline
 2016-09-19 00:40:03 +02:00
Maxim Ivanov bdc53098fc Avoid having contended mutexes on same cacheline 
CPUs have to serialise write access to a single cache line
effectively reducing level of possible parallelism. Placing
mutexes on different cache lines avoids this problem.

Most gains will be seen on NUMA servers where CPU interconnect
traffic is especially expensive

Before:
go test . -run none -bench BenchmarkFingerprintLocker
