Fabian Reinartz cc0ff26f1f retrieval: handle GZIP compression ourselves
The automatic GZIP handling of net/http does not preserve
buffers across requests and thus generates a lot of garbage.
We handle GZIP ourselves to circumvent this.t

Fabian Reinartz 5772f1a7ba retrieval/storage: adapt to new interface
This simplifies the interface to two add methods for
appends with labels or faster reference numbers.

Brian Brazil 34767c2221 Clone lset before relabelling. (#2386)
We need to not change the lset passed into populateLabels, as that
is kept around by the SDs.

Fabian Reinartz c691895a0f retrieval: cache series references, use pkg/textparse
With this change the scraping caches series references and only
allocates label sets if it has to retrieve a new reference.
pkg/textparse is used to do the conditional parsing and reduce
allocations from 900B/sample to 0 in the general case.

beorn7 5dc01202d7 Retrieval: Remove some test lines that fail on Travis only
These lines exercise an append in
TestScrapeLoopWrapSampleAppender. Arguably, append shouldn't be tested
there in the first place.

Still it's weird why this fails on Travis:

```
--- FAIL: TestScrapeLoopWrapSampleAppender (0.00s)
    scrape_test.go:259: Expected count of 1, got 0
    scrape_test.go:290: Expected count of 1, got 0

FAIL

```

Should anybody ever find out why, please revert this commit accordingly.

beorn7 3610331eeb Retrieval: Do not buffer the samples if no sample limit configured
Also, simplify and streamline the code a bit.

beorn7 767c0709b1 Retrieval: Avoid copying Target
retreival.Target contains a mutex. It was copied in the Targets()
call. This potentially can wreak a lot of havoc.

It might even have caused the issues reported as #2266 and #2262 .

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

Fabian Reinartz b4d7ce1370 discovery: respect context cancellation everywhere
This also removes closing of the target group channel everywhere

draining all events once that happened.

Brian Brazil bbec65d454 Call SD metrics refresh rather than scrape. (#2120)
This avoids confusion with scrape_duration_seconds, and
is more in line with the API naming.
