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.

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.

Brian Brazil 850ea412ad If an explicit timestamp is provided, bypass staleness. 2017-05-16 18:33:51 +01:00
Brian Brazil a5cf25743c Move stalness check into a function 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.

Brian Brazil fcc88f0e1e query/query_range should return eval timestamp 
Query and query_range should return the timestamp
at which an evaluation is performed, not the timestamp
of the data. This is as that's what query range asked
for, and we need to keep query consistent with that.

Query for a matrix remains unchanged, returning the literal
matrix.
 2017-05-12 12:00:31 +01:00
Brian Brazil 517b81f927 Add timestamp() function. 
Make the timestamp of instant vectors be the timestamp of the sample
rather than the evaluation. We were not using this anywhere, so this is
safe.

Add a function to return the timestamp of samples in an instant vector.

Fixes #1557
