Thomas Jackson	404abe0f1c	Bubble up errors to promql from populating iterators (#4136 ) This changes the Walk/Inspect API inside the promql package to bubble up errors. This is done by having the inspector return an error (instead of a bool) and then bubbling that up in the Walk. This way if any error is encountered in the Walk() the walk will stop and return the error. This avoids issues where errors from the Querier where being ignored (causing incorrect promql evaluation).

David King	6286c10df0	Fix OOM when a large K is used in topk queries (#4087 ) This attempts to close #3973. Handles cases where the length of the input vector to an aggregate topk / bottomk function is less than the K paramater. The change updates Prometheus to allocate a result vector the same length as the input vector in these cases. Previously Prometheus would out-of-memory panic for large K values. This change makes that unlikely unless the size of the input vector is equally large. Signed-off-by: David King <dave@davbo.org>	7 years ago

Brian Brazil	67274f0794	Remove 4 interval staleness heuristic. (#3244 ) This means that if there is no stale marker, only the usual staleness delta (5m) applies. It has occured to me that there is an oddity in the heurestic. It works fine as long as you have 2 points within the last 5m, but breaks down when the time window advances to the point where you have just 1 point. Consider you had points at t=0 and t=10. With the heurestic it goes stale at t=51, up until t=300. However from t=301 until t=310 we only see the t=10 point and the series comes back to life. That is not desirable. I don't see a way to keep this form of heurestic working given this issue, so thus I'm removing it.	7 years ago

Brian Brazil	220e78b9c3	Consider a series stale after 4.1 intervals with no data. To cover the cases where stale markers may not be available, we need to infer the interval and mark series stale based on that. As we're lacking stale markers this is less accurate, however it should be good enough for these cases. We need 4 intervals as if say we had data at t=0 and t=10, coming via federation. The next data point should be at t=20 however it could take up to t=30 for it actually to be ingested, t=40 for it to be scraped via federation and t=50 for it to be ingested. We then add 10% on to that for slack, as we do elsewhere.	8 years ago

Jack Neely	896f951e68	Force buckets in a histogram to be monotonic for quantile estimation (#2610 ) * Force buckets in a histogram to be monotonic for quantile estimation The assumption that bucket counts increase monotonically with increasing upperBound may be violated during: * Recording rule evaluation of histogram_quantile, especially when rate() has been applied to the underlying bucket timeseries. * Evaluation of histogram_quantile computed over federated bucket timeseries, especially when rate() has been applied This is because scraped data is not made available to RR evalution or federation atomically, so some buckets are computed with data from the N most recent scrapes, but the other buckets are missing the most recent observations. Monotonicity is usually guaranteed because if a bucket with upper bound u1 has count c1, then any bucket with a higher upper bound u > u1 must have counted all c1 observations and perhaps more, so that c >= c1. Randomly interspersed partial sampling breaks that guarantee, and rate() exacerbates it. Specifically, suppose bucket le=1000 has a count of 10 from 4 samples but the bucket with le=2000 has a count of 7, from 3 samples. The monotonicity is broken. It is exacerbated by rate() because under normal operation, cumulative counting of buckets will cause the bucket counts to diverge such that small differences from missing samples are not a problem. rate() removes this divergence.) bucketQuantile depends on that monotonicity to do a binary search for the bucket with the qth percentile count, so breaking the monotonicity guarantee causes bucketQuantile() to return undefined (nonsense) results. As a somewhat hacky solution until the Prometheus project is ready to accept the changes required to make scrapes atomic, we calculate the "envelope" of the histogram buckets, essentially removing any decreases in the count between successive buckets. * Fix up comment docs for ensureMonotonic * ensureMonotonic: Use switch statement Use switch statement rather than if/else for better readability. Process the most frequent cases first.	8 years ago
