Brian Brazil bf38963118 Plumb through logger with target field to scrape loop. 2017-05-16 18:33:51 +01:00
Brian Brazil d657d722dc Log count of dupliates/out of order samples as warnings.
Keep log of each sample as debug log.

Brian Brazil d532272520 Add stalemarkers to synthetic series too when target stops. 2017-05-16 18:33:51 +01:00
Brian Brazil b87d3ca9ea Create stale markers when a target is stopped.
When a target is no longer returned from SD stop()
is called. However it may be recreated before the
next scrape interval happens. So we wait to set stalemarkers
until the scrape of the new target would have happened
and been ingested, which is 2 scrape intervals.

If we're shutting down the context will be cancelled,
so return immediately rather than holding things up for potentially
minutes waiting to safely set stalemarkers no newer than now.
If the server starts immediately back up again all is well.
If not, we're missing some stale markers.

Brian Brazil 95162ebc16 Add log messages for out of order samples 2017-05-16 18:33:51 +01:00
Brian Brazil 3c45400130 Don't fail scrape if one sample violates ordering.
In Prometheus 1.x one sample that is out of order
or that has a duplicate timestamp is discarded, and
the rest of the scrape ingestion continues on.
This will now also be true for 2.0.

Brian Brazil fd5c5a50a3 Add stale markers on parse error.
If we fail to parse the result of a scrape,
we should treat that as a failed scrape and
add stale markers.
2017-05-16 18:33:51 +01:00
Brian Brazil c0c7e32e61 Treat a failed scrape as an empty scrape for staleness.
If a target has died but is still in SD, we want the previously
scraped values to go stale. This would also apply to brief blips.

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:

```

Brian Brazil f421ce0636 Remove label from prometheus_target_skipped_scrapes_total (#2289)

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.
