 2013-05-28 05:35:31 -07:00

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.

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.

Interval value extraction fixes and optimizations.
 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.
 2013-05-22 18:14:45 +02:00
Julius Volz 83d60bed89 extractValuesAroundTime() code simplification. 2013-05-22 18:14:45 +02:00
Julius Volz 008314b5a8 Ensure that all extracted samples are added to view. 
The current behavior only adds those samples to the view that are extracted by
the last pass of the last processed op and throws other ones away. This is a
bug. We need to append all samples that are extracted by each op pass.

This also makes view.appendSamples() take an array of samples.

Simple LevelDB sample dumper tool.
 2013-05-22 07:18:53 -07:00
Julius Volz 6d68626125 Simple LevelDB sample dumper tool. 
This very simple tool dumps all samples in a LevelDB metrics storage
together with their chunk information. This is very crude for now - I
just whipped it up because I needed to debug something. We should add
printf-style formatting support for it in the future to indicate what
information to output for each sample in the database. We could also
support inspecting the index databases.

Julius Volz 8586c7520c Support negative graph values. 
Currently graph Y-Axes were hardcoded to start at 0. Choose the Y-scale
automatically based on the graph data instead.

juliusv 1958063cc7 Merge pull request #262 from prometheus/feature/storage/fix-grouping 
Spawn grouping of fingerprints with free semaphore.
 2013-05-21 07:17:51 -07:00
Matt T. Proud 74a66fd938 Spawn grouping of fingerprints with free semaphore. 
The previous implementation spawned N goroutines to group samples
together and would not start work until the semaphore unblocked.
While this didn't leak, it polluted the scheduling space.  Thusly,
the routine only starts after a semaphore has been acquired.

Matt T. Proud e5ac91222b Benchmark memory arena; simplify map generation. 
The one-off keys have been replaced with ``model.LabelPair``, which is
indexable.  The performance impact is negligible, but it represents
a cognitive simplification.

Several Refactorings: Simplified Encoder / Reduction of Naked Return Values
 2013-05-16 07:01:27 -07:00
Matt T. Proud 8f4c7ece92 Destroy naked returns in half of corpus. 
The use of naked return values is frowned upon.  This is the first
of two bulk updates to remove them.
 2013-05-16 10:53:25 +03:00
Matt T. Proud 4e0c932a4f Simplify Encoder's encoding signature. 
The reality is that if we ever try to encode a Protocol Buffer and it
fails, it's likely that such an error is ultimately not a runtime error
and should be fixed forthwith.  Thusly, we should rename
``Encoder.Encode`` to ``Encoder.MustEncode`` and drop the error return
value.

Matt T. Proud b063338ae6 Expand the in-memory arena size. 
We need to exercise this code path sooner versus later.  This will
be a cheap way of doing so.
