Julius Volz e681a57d73 Merge pull request #641 from prometheus/stddev 
Add stddev and stdvar aggregation functions.
 2015-04-17 01:36:44 +02:00
Brian Brazil c3a2b63fe9 Add stddev and stdvar aggregation functions. 
This adds the population standard deviation and
variance as aggregation functions, useful for
spotting how many standard deviations some samples
are from the mean.

beorn7 b02d900e61 Improve chunk and chunkDesc loading. 
Also, clean up some things in the code (especially introduction of the
chunkLenWithHeader constant to avoid the same expression all over the place).

Benchmark results:

BEFORE
BenchmarkLoadChunksSequentially     5000            283580 ns/op          152143 B/op        312 allocs/op
BenchmarkLoadChunksRandomly        20000             82936 ns/op           39310 B/op         99 allocs/op
BenchmarkLoadChunkDescs            10000            110833 ns/op           15092 B/op        345 allocs/op

AFTER
BenchmarkLoadChunksSequentially    10000            146785 ns/op          152285 B/op        315 allocs/op
BenchmarkLoadChunksRandomly        20000             67598 ns/op           39438 B/op        103 allocs/op
BenchmarkLoadChunkDescs            20000             99631 ns/op           12636 B/op        192 allocs/op

Note that everything is obviously loaded from the page cache (as the
benchmark runs thousands of times with very small series files). In a
real-world scenario, I expect a larger impact, as the disk operations
will more often actually hit the disk. To load ~50 sequential chunks,
this reduces the iops from 100 seeks and 100 reads to 1 seek and 1
read.

beorn7 c5fa0b90c3 Fix the case where a series in memory has 0 chunks, but chunks on disk. 
This is actually completely normal for a freshly unarchived series.

Tobias Schmidt 49d67fc834 Merge pull request #629 from prometheus/improve-usage-formatting 
Improve readability of usage text
 2015-04-08 17:51:29 -04:00
Tobias Schmidt 7d71d354fd Remove special listing of config.file in usage 
The -config.file parameter isn't required or any more special than the
other flags. In order to avoid confusion, this change removes the
special mention again. Instead, the error message if a config file
couldn't be loaded is changed to mention the flag name.
 2015-04-08 17:36:15 -04:00
Tobias Schmidt 35a44509fb Improve readability of usage text 
Separates flag and description by a newline to make it easier to read
the flags with long descriptions.

This commit increases the usability by grouping flags based on their
first dot-separated group. Long flag descriptions are broken into lines
printed with indentation.

beorn7 3035b8bfdd Adaptively reduce the wait time for memory series maintenance. 
This will make in-memory series maintenance the faster the more chunks
are waiting for persistence.

Julius Volz 9f198cc7b5 Merge pull request #619 from fabxc/fabxc/rule_checker 
Increase the usability of the rule_checker CLI.
 2015-04-01 16:36:56 +02:00
Fabian Reinartz c4e762adbf Increase the usability of the rule_checker CLI. 
This commit allows to invoke the rule_checker with a chain of
filepaths as arguments. If no paths are provided it reads from standard
input.
The -rule-file flag remains for backward-compatibility.
On processing errors the return code is now 1. For bad arguments
the return code is now 2.
