Brian Brazil d657d722dc Log count of dupliates/out of order samples as warnings. 
Keep log of each sample as debug log.

Brian Brazil 8b9d3e7547 Put end of run staleness handler in seperate function. 
Improve log message.
 2017-05-16 18:33:51 +01:00
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.
 2017-05-16 18:33:51 +01:00
Brian Brazil 73049ba79d Make the choice of NaN values clearer. 
Also switch stale nan value to one more suitable for expansion.
 2017-05-16 18:33:51 +01:00
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.
 2017-05-16 18:33:51 +01:00
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.
 2017-05-16 18:33:51 +01:00
Brian Brazil 850ea412ad If an explicit timestamp is provided, bypass staleness. 2017-05-16 18:33:51 +01:00

Brian Brazil 80b40e6d91 Add initial staleness handing to promql. 
For instant vectors, if "stale" is the newest sample
ignore the timeseries.

For range vectors, filter out "stale" samples.

Make it possible to inject "stale" samples in promql tests.
