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.

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
2017/01/07 22:48:26 http: TLS handshake error from 127.0.0.1:50716: read tcp 127.0.0.1:40265->127.0.0.1:50716: read: connection reset by peer
FAIL
FAIL	github.com/prometheus/prometheus/retrieval	3.603s
```

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
 2016-12-16 15:10:09 +00:00
Brian Brazil c8de1484d5 Add scrape_samples_post_metric_relabeling 
This reports the number of samples post any keep/drop
from metric relabelling.

Fabian Reinartz b4d7ce1370 discovery: respect context cancellation everywhere 
This also removes closing of the target group channel everywhere
as the contexts cancels across all stages and we don't care about
draining all events once that happened.

Brian Brazil 64263f280d Add scrape_samples_scraped to indicate samples scraped. (#2123) 2016-10-26 17:43:01 +01:00
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.
