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.

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.

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

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.

Tristan Colgate-McFarlane 4d9134e6d8 Add labeldrop and labelkeep actions. (#2279)
Introduce two new relabel actions. labeldrop, and labelkeep.
These can be used to filter the set of labels by matching regex

- labeldrop: drops all labels that match the regex
- labelkeep: drops all labels that do not match the regex

storage: Sanity-check number of loaded chunk descs
2016-12-14 02:59:10 +01:00
beorn7 253be23c00 storage: Sanity-check number of loaded chunk descs
Two cases:

- An unarchived metric must have at least one chunk desc loaded upon
  unarchival. Otherwise, the file is gone or has size 0, which is an
  inconsistency (because the series is still indexed in the archive
  index). Hence, quarantining is triggered.

- If loading the chunk descs of a series with a known chunkDescsOffset
  (i.e. != -1), the number of chunks loaded must be equal to
  chunkDescsOffset. If not, there is a data corruption. An error is
  returned, which leads to qurantining.

In any case, there is a guard added to not access the 1st element of
an empty chunkDescs slice. (That's what triggered the crashes in issue
2249.)  A time series with unknown chunkDescsOffset and no chunks in
memory and no chunks on disk either could trigger that case. I would
assume such a "null series" doesn't exist, but it's not entirely
unthinkable and unreasonable to happen (perhaps in future uses of the
storage). (Create a series, and then something tries to preload chunks
before the first sample is added.)

Fabian Reinartz 9d68e81b32 web: don't return federation errors over HTTP
We are writing federation responses streaming. So after
the first byte we wrote, the status header is fixed. We cannot
return an HTTP error for intermediate error but should just abort
and log instead.
