Fabian Reinartz 8b84ee5ee6 storage: remove old storage 
This removes all old storage files and only keeps interfaces
to still allow the code to compile.

Fabian Reinartz 11a731ba82 remote: remove hard-coded remote storages 
This commit removes the flag-configured remote storage integrations
in favor of the generic remote write path.

Brian Brazil 93b70ee4ea Evict chunk descs of all unloaded chunks during maintenance. (#2297) 
Keeping these around has two problems:
1) Each desc takes 64 bytes, 10 of them is 640B. This is a lot of
overhead on a 1024 byte chunk.
2) It can take well over a week to reach a point where this and thus
Prometheus memory usage as a whole enters steady state. This makes RAM
estimation very hard for users, and makes it difficult to investigate
things like memory fragmentation.

Instead we'll wipe them during each memory series maintenance cycle, and
if a query pulls them in they'll hang around as cache until the next
cycle.

Fabian Reinartz d6d03a966f Merge pull request #2295 from prometheus/fast-path-remote 
Don't clone the metric if there's no remote writes.
 2016-12-21 12:36:41 +01:00
Brian Brazil 1b8a474612 Don't clone the metric if there's no remote writes. 
The metric clone can't be further optimised, and is a
non-trivial memory allocation cost so fast path it
if there's no remote writes configured.
 2016-12-21 11:34:48 +00:00
Brian Brazil 6c07453ec1 Only clone the metric in the one place relabelling needs it. (#2292) 
This cuts ~17% off memory allocations related to ingesting data
in a basic setup.

Brian Brazil f421ce0636 Remove label from prometheus_target_skipped_scrapes_total (#2289) 
This avoids it not being intialised, and breaking out by
interval wasn't partiuclarly useful.

Fixes #2269
 2016-12-16 18:00:52 +00:00
Brian Brazil 30448286c7 Add sample_limit to scrape config. 
This imposes a hard limit on the number of samples ingested from the
target. This is counted after metric relabelling, to allow dropping of
problemtic metrics.

This is intended as a very blunt tool to prevent overload due to
misbehaving targets that suddenly jump in sample count (e.g. adding
a label containing email addresses).

Add metric to track how often this happens.

Fixes #2137
 2016-12-16 15:10:09 +00:00
Fabian Reinartz b08f82fa4e Pre-select relevant chunks on series access. 
This adds interval metadata to indexed chunks. The queried interval
is used to filter chunks when queried from the index to save
unnecessary accesses of the chunks file.

This is especially relevant for series that come and go often and larger
files.
