Handle a bunch of unchecked errors (#4461) 
There are many more (mostly finalizers like Close/Stop/etc.), but most of
the others seemed like one couldn't do much about them anyway.

Fabian Reinartz 7ccd4b39b8 *: implement query params 
This adds a parameter to the storage selection interface which allows
query engine(s) to pass information about the operations surrounding a
data selection.
This can for example be used by remote storage backends to infer the
correct downsampling aggregates that need to be provided.

beorn7 c2e9a151ab Make all rule links link to the "Console" tab rather than "Graph" 
Clicking on a rule, either the name or the expression, opens the rule
result (or the corresponding expression, repsectively) in the
expression browser. This should by default happen in the console tab,
as, more often than not, displaying it in the graph tab runs into a
timeout.

Brian Brazil dcea3e4773 Don't append a 0 when alert is no longer pending/firing 
With staleness we no longer need this behaviour.
 2017-05-24 13:52:45 +01:00
Brian Brazil cc867dae60 Copy previous series and alert state more intelligently. 
Usually rules don't more around, and if they do it's likely
that rules/alerts with the same name stay in the same order.

If rules/alerts with the same name are added/removed this
could cause a blip for one cycle, but this is unavoidable
without requiring rule and alert names to be unique - which we don't
want to do.

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:

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.

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.

beorn7 75bae065fd Revert "Modify tests to adjust to reverting the /graph changes" 
This reverts commit f1ea5bf232.

Part two necessary for reverting the /graph revert.

beorn7 f1ea5bf232 Modify tests to adjust to reverting the /graph changes 
These tests have been added after the /graph changes and therefore
already test the new syntax.

This commit has to be reverted together with the previous one to get
back to the old new state. *sigh*

beorn7 064b57858e Consistently use the Seconds() method for conversion of durations 
This also fixes one remaining case of recording integral numbers
of seconds only for a metric, i.e. this will probably fix #1796.

beorn7 45e5775f9b Add missing logging of out-of-order samples 
So far, out-of-order samples during rule evaluation were not logged,
and neither scrape health samples. The latter are unlikely to cause
any errors. That's why I'm logging them always now. (It's alway highly
irregular should it happen.) For rules, I have used the same plumbing
as for samples, just with a different wording in the message to mark
them as a result of rule evaluation.

beorn7 4b574e8a61 Switch chunk encoding to type 2 where it was hardcoded type 1 before 
The chunk encoding was hardcoded there because it mostly doesn't
matter what encoding is chosen in that test. Since type 1 is
battle-hardened enough, I'm switching to type 2 here so that we can
catch unexpected problems as a byproduct. My expectation is that the
chunk encoding doesn't matter anyway, as said, but then "unexpected
problems" contains the word "unexpected".

Fabian Reinartz d89c254849 Make copying alerting state safer. 
This considers static labels in the equality of alerts to
avoid falsely copying state from a different alert definition with
the same name across reloads.

To be safe, it also copies the state map rather than just its pointer
so that remaining collisions disappear after one evaluation interval.
