Julius Volz 5d88e8cc45 Round time to nearest second in memory storage. 
When samples get flushed to disk, they lose sub-second precision anyways. By
already dropping sub-second precision, data fetched from memory vs. disk will
behave the same. Later, we should consider also storing a more compact
representation than time.Time in memory if we're not going to use its full
precision.

Matt T. Proud 4d15f8fefe Merge pull request #331 from prometheus/fix/retrieval/payload-extraction-buffering 
Completely extract response payload for decoding.
 2013-07-15 02:38:40 -07:00
Matt T. Proud e20e6980e9 Completely extract response payload for decoding. 
This commit forces the extraction framework to read the entire response payload
into a buffer before attempting to decode it, for the underlying Protocol Buffer
message readers do not block on partial messages.

Matt T. Proud b85ca7c657 Merge pull request #328 from prometheus/scrape-old-targets-on-sd-fail 
Continue scraping old targets on SD fail.
 2013-07-12 13:51:57 -07:00
Julius Volz 9a48f57b66 Continue scraping old targets on SD fail. 
When we have trouble resolving the targets for a job via service
discovery, we shouldn't just stop scraping the targets we currently
have.

juliusv 8f0a3a060c Merge pull request #327 from prometheus/optimize/faster-lexer 
Swap rules lexer for much faster one.
 2013-07-11 11:08:20 -07:00
Julius Volz 64b0ade171 Swap rules lexer for much faster one. 
This swaps github.com/kivikakk/golex for github.com/cznic/golex.

The old lexer would have taken 3.5 years to load a set of 5000 test rules
(quadratic time complexity for input length), whereas this one takes only 32ms.
Furthermore, since the new lexer is embedded differently, this gets rid of the
global parser variables and makes the rule loader fully reentrant without a
lock.

 2013-06-27 09:52:00 -07:00
Matt T. Proud b8c7fd8c34 Include Accept header for telemetry request. 
This pull request introduces a HTTP Accept header to indicate a
preference for Protocol Buffer-encoded messages.

Julius Volz a76a797f3f Always treat series without watermarks as too old. 
Current series always get watermarks written out upon append now. This
drops support for old series without any watermarks by always reporting
them as too old (stale) during queries.

juliusv 0a69119f7b Merge pull request #316 from prometheus/refactor/range-at-interval-op 
Implement getValueRangeAtIntervalOp for faster range queries.
 2013-06-26 09:13:17 -07:00
Julius Volz d2da21121c Implement getValueRangeAtIntervalOp for faster range queries. 
This also short-circuits optimize() for now, since it is complex to implement
for the new operator, and ops generated by the query layer already fulfill the
needed invariants. We should still investigate later whether to completely
delete operator optimization code or extend it to support
getValueRangeAtIntervalOp operators.

Adjust LevelDB Defaults
 2013-06-24 03:55:22 -07:00
Matt T. Proud b811ccc161 Disable paranoid checks and expose max FDs option. 
We shouldn't need paranoid checks now.  We also shouldn't need
too many FDs being open due to rule evaluator hitting in-memory
values stream.

Matt T. Proud 4137c75523 Shrink default LRU cache sizes.

safely.

Matt T. Proud 3784b1779f Upgrade LevelDB to 1.12.0. 
A number of core fixes have occurred in upstream LevelDB.  Given API
compatibility, we should upgrade.

This commit ensures that series that exist only in-memory and not
on-disk are not regarded as too old for operation exclusion.

Matt T. Proud a1a23fbaf8 Ensure new metrics are watermarked early. 
With the checking of fingerprint freshness to cull stale metrics
from queries, we should write watermarks early to aid in more
accurate responses.
