Harold Dost	bf7c771f54	promql: Organize legacy tests into appropriate files (#7989) ... * Separate tests into: ** Aggregators ** Functions ** Operators ** Selectors * Remove simple files and place tests into other files. * Eliminate some of the _over_time tests since there are already plenty of edge cases present in the functions.test file. Relates to #740 Signed-off-by: Harold Dost <harolddost@gmail.com>	4 years ago

Brian Brazil	858c363e94	Fix panic when aggregator param is not a literal. ... The return value for checkForSeriesSetExpansion is always nil, simplify. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	6 years ago
Dan Cech	9f4cb06a37	use Welford/Knuth method to compute standard deviation and variance (#4533) ... * use Welford/Knuth method to compute standard deviation and variance, avoids float precision issues * use better method for calculating avg and avg_over_time Signed-off-by: Dan Cech <dcech@grafana.com>	6 years ago
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	16690736ab	Add count_values() aggregator. ... This is useful for counting how many instances of a job are running a particular version/build. Fixes #622	9 years ago
Brian Brazil	fa9cc15573	Add topk/bottomk tests for multiple buckets.	9 years ago
Brian Brazil	3b0c182eee	Move topk/bottomk unittests over to aggregators.	9 years ago
Brian Brazil	3b89616d82	Allow on, ignoring, by and without wit empty laberls. ... This offers new semantics in allowing on() for matching two single-element vectors with no known common labels. Previosuly this was often done using on(dummy). This also allows making it explict that you meant to do an aggregation without labels via by(). Fixes #1597.	9 years ago
Brian Brazil	9d0112d7cf	Add without aggregator modifier. ... This has the advantage that the user doesn't need to list all labels they want to keep (as with "by") but without having to worry about inconsistent labels as when there's only one time series (as with "keeping_common"). Almost all aggregation should use this rather than the existing two options as it's much less error prone and easier to maintain due to not having to always add in "job" plus whatever other common job-level labels you have like "region".	9 years ago
