Vector matching
- ignoring
- group_left
- group_right
Aggregation
- Aggregation operators can be used to aggregate all dimensions or preserve some dimensions using
without: removes the listed labels from the result vector-
by: drops labels not listed in the by clause -
sum: calculate sum over dimensions
- min: select minimum over dimensions
- max: select maximum over dimensions
- avg: calculate the average over dimensions
- group: all values in the resulting vector are 1
- stddev: calculate population standard deviation over dimensions
- stdvar: calculate population standard variance over dimensions
- count: count number of elements in the vector
- count_values: count number of elements with the same value
- bottomk: smallest k elements by sample value
- topk: largest k elements by sample value
- quantile: calculate φ-quantile (0 ≤ φ ≤ 1) over dimensions
sum without (instance) (http_requests_total)
sum by (application, group) (http_requests_total)
sum(http_requests_total)
count_values("version", build_version)
topk(5, http_requests_total)
# all distinct metrics given a certain label value
group({service="insurance-payments"}) by (__name__)
