Julius Volz	00a2a93a05	Add regression tests for metrics mutations in AST. ... It turned out in the end, that only drop_common_metrics() produced any erroneous output in the old system. The second expression in the test ("sum(testmetric) keeping_extra") already worked in the old code, but why not keep it in... The way to test ranged evaluations is a bit clumsy so far, so I want to build a nicer test framework in the end, where all the test cases can be specified as text files which specify desired inputs, outputs, query step widths, etc. Change-Id: I821859789e69b8232bededf670a1b76e9e8c8ca4	10 years ago

Julius Volz	b7bf11230a	Add absent() function. ... A common problem in Prometheus alerting is to detect when no timeseries exist for a given metric name and label combination. Unfortunately, Prometheus alert expressions need to be of vector type, and "count(nonexistent_metric)" results in an empty vector, yielding no output vector elements to base an alert on. The newly introduced absent() function solves this issue: ALERT FooAbsent IF absent(foo{job="myjob"}) [...] absent() has the following behavior: - if the vector passed to it has any elements, it returns an empty vector. - if the vector passed to it has no elements, it returns a 1-element vector with the value 1. In the second case, absent() tries to be smart about deriving labels of the 1-element output vector from the input vector: absent(nonexistent{job="myjob"}) => {job="myjob"} absent(nonexistent{job="myjob",instance=~".*"}) => {job="myjob"} absent(sum(nonexistent{job="myjob"})) => {} That is, if the passed vector is a literal vector selector, it takes all "=" label matchers as the basis for the output labels, but ignores all non-equals or regex matchers. Also, if the passed vector results from a non-selector expression, no labels can be derived. Change-Id: I948505a1488d50265ab5692a3286bd7c8c70cd78	10 years ago
Julius Volz	3d47f94149	Drop metric names after transformations. ... After many transformations, it doesn't make sense to keep the metric names, since the result of the transformation is no longer that metric. This drops the metric name after such transformations and makes the web UI deal well with missing metric names. This depends on the current branch on the following things: - prometheus/client_golang needs to be at e237cf15c6 in branch "julius/int-fingerprints" (to be merged with new storage) - prometheus/promdash needs to be at dd7691c9c2 Change-Id: Ib3c8cad8d647d9854e8c653c424b8c235ccc231d	10 years ago
