I want to find anomalies for the number of registrations my web app gets. Similar to how offset modifier lets you offset the evaluation of vector selector, range vector selector, and subqueries by a fixed duration relative to the evaluation time, the @ modifier lets you fix the evaluation for those selectors irrespective of the query evaluation time. This offset corresponds to the position of the series in the postings section. consumer JMX metrics are only present on the consumer processes themselves, not on the Kafka broker processes. 1 Using Grafana Variable in Prometheus Query.
