Matt T. Proud 86f63b078b Fix fallthrough compaction value ordering.
We discovered a regression whereby data chunks could be appended out
of order if the fallthrough case was hit.

Cleanups in tiered storage and apply semaphores.
2013-06-06 09:16:53 -07:00
Matt T. Proud ef1d5fd8a2 Introduce semaphores for tiered storage.
This commit wraps the tiered storage access componnets in semaphores,
since we can handle several concurrent memory reads.

Matt T. Proud beaaf386e7 Add storage state guards and transition callbacks.
To ensure that we access tiered storage in the proper way, we have
guards now.

2013-06-06 02:33:27 -07:00
Matt T. Proud 2c3df44af6 Ensure database access waits until it is started.
This commit introduces a channel message to ensure serving
state has been reached with the storage stack before anything attempts
to use it.

juliusv 115437ad1f Merge pull request #278 from prometheus/debug/query-timings
Add debug timers to instant and range queries.
2013-06-05 09:41:51 -07:00
Julius Volz 51689d965d Add debug timers to instant and range queries.
This adds timers around several query-relevant code blocks. For now, the
query timer stats are only logged for queries initiated through the UI.
In other cases (rule evaluations), the stats are simply thrown away.

My hope is that this helps us understand where queries spend time,
especially in cases where they sometimes hang for unusual amounts of
time.

Matt T. Proud 9cde48754b Fix race conditions in TargetPool.
The race condition detector found a few anomalies whereby a
TargetPool could be read during a mutation.  This has been fixed.

Julius Volz adb87816f4 Put RuleManager concurrency in hands of caller, fix races. 2013-06-05 13:56:56 +02:00
Matt T. Proud 9215580488 Include race condition binary target.
The race condition binary target is special in that it needs to
explicitly link against the dependent libraries and recompile the CGO
bindings.  Because of this, we have a new build target that produces
these binaries.

Conditionalize disk initializations.
2013-06-04 04:25:16 -07:00
Matt T. Proud 8339a189cb Code Review: Fix seriesPresent scope.
The seriesPresent scope should be constrained to the scope of a
scanJob, since this is keyed to given series.
2013-06-04 13:16:59 +02:00
Matt T. Proud fe41ce0b19 Conditionalize disk initializations.
This commit conditionalizes the creation of the diskFrontier and
seriesFrontier along with the iterator such that they are provisioned
once something is actually required from disk.

juliusv 97736a030a Merge pull request #277 from prometheus/feature/exporter-prefix
Prepend "exporter_" to labels that already exist in exported metrics.
2013-06-03 01:46:17 -07:00
Julius Volz dcfd09c801 Prepend "exporter_" to labels that already exist in exported metrics.
If the metrics exported by a process already contain any of a target's
base labels (such as "job" or "instance", but also any manually assigned
target-group label), don't overwrite that label, but instead add a new
label consisting of the original label name prepended with "exporter_".
This is to accomodate intermediate exporter jobs, which might indicate
e.g. the jobs and instances for which they are exporting data.

Include uptime in the status console.
2013-05-24 02:02:28 -07:00
Matt T. Proud 0d2d6e9a27 Include uptime in the status console.
In order to help corroborate whether a Prometheus instance has
flapped until meta-monitoring is in-place, we ought to provide the
instance's start time in the console to aid in diagnostics.
2013-05-24 10:44:34 +02:00
Matt T. Proud c10780c966 Introduce telemetry for rule evaluator durations.
This commit adds telemetry for the Prometheus expression rule
evaluator, which will enable meta-Prometheus monitoring of customers
to ensure that no instance is falling behind in answering routine
queries.

A few other sundry simplifications are introduced, too.

2013-05-22 09:24:46 -07:00
Julius Volz f2b48b8c4a Make getValuesAtIntervalOp consume all chunk data in one pass.
This is mainly a small performance improvement, since we skip past the last
extracted time immediately if it was also the last sample in the chunk, instead
of trying to extract non-existent values before the chunk end again and again
and only gradually approaching the end of the chunk.
