Can you give examples of the metrics in question, and what conditions you're trying to check for?
Looking at your specific PromQL query: Firstly, in my experience, it's very unusual in Prometheus queries to use ==bool or >bool, and in this specific case definitely seems to be wrong. Secondly, you won't be able to join the LH and RH sides of your expression with "and" unless either they have exactly the same label sets, or you modify your condition using "and on (...)" or "and ignoring (...)". "and" is a vector intersection operator, where the result vector includes a value if the labels match, and the value is taken from the LHS, and that means it doesn't combine the values like you might be used to in other programming languages. For example, vector(0) and vector(1) => value is 0 vector(1) and vector(0) => value is 1 vector(42) and vector(99) => value is 42 This is as described in the documentation <https://prometheus.io/docs/prometheus/latest/querying/operators/#logical-set-binary-operators> : vector1 and vector2 results in a vector consisting of the elements of vector1 for which there are elements in vector2 with exactly matching label sets. Other elements are dropped. The metric name and values are carried over from the left-hand side vector. PromQL alerts on the presence of values, and in PromQL you need to think in terms of "what (labelled) values are present or absent in this vector", using the "and/unless" operators to suppress elements in the result vector, and the "or" operator to add additional elements to the result vector.
