Prometheus offset Note about native histograms (experimental feature): To scrape native histograms via federation, the scraping Prometheus server needs to run with native histograms enabled (via the command line flag --enable-feature=native-histograms), implying that the protobuf format is Prometheus 是一个开源的系统监控和警告工具包，最初由 SoundCloud 开发并广泛使用于各种环境中。它使用拉取模式从目标中收集数据，并允许用户通过灵活的查询语言 PromQL 对收集到的数据进行查询和分析。 Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Prometheus exporter for NTP offset/stratum of a client Resources. ), the configuration file defines everything related to scraping jobs and their instances, as well as which rule files to load. While a Prometheus server that collects only data about itself is not very useful, it is a good starting example. I know the offset can be calculated by time() % 86400 as in the number of seconds since midnight but prometheus does not accept dynamic offset values as The provided query is valid MetricsQL query for VictoriaMetrics, but unfortunately it doesn't work in the original PromQL.

Offset modifier The offset modifier allows changing the time offset for individual instant and range vectors in a query. 51 stars. As a user, one only wants to get a single page while still being able to see exactly which service instances were affected. Prometheus works via a pull-model so we need to expose the lag in a format so that Prometheus can scrape and read it. This time is the actual time offset of the local clock. Operators in PromQL. So either > or < may be used for filtering NaN values before aggregating them with aggregate functions. 0 or higher. however, i want to see data from the past 14 days. The instant vector and range vector are indeed confusing terms in Prometheus. What I'm looking for is simply to tell Grafana that it should display 'now' as 'now-1d'.

This offset corresponds to the position of the series in the postings section. Monitor number of seconds since metric change as prometheus time series. delta(vss_device_number[1d]) The query returns deltas per each matching time series. Improve this answer. With offset, you can request the value from a certain amount of time before the moment the query was done. For example, the following query should return the delta for vss_device_number over the last day (see [1d]):. promql_dst_offset This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. This can be fixed by adding offset -1d inside the query: last_over_time( avg_over_time(metric[1d] offset -1d)[1d:1d] ) Unfortunately the given query with negative offset doesn't work in Prometheus older than v2. The lookbehind window can be augmented on a per-query basis via last_over_time() function. I go into instant and range vector selectors, label matchers, the 5-minute l * Implement offset modifier for range vector aggregation in LogQL implementation for #2785, the offset modifier allows changing the time offset for range vectors in a query to support e. prometheus_http_requests_total{code=~"2. 1. ) The identifying They are a concept that touches almost every part of the Prometheus stack.

Currently, there are no available JMX metrics for consumer lag from the Kafka broker itself. Prometheus自带了很多很强大的计算函数。offset算是一个用得比较多的，下面是一个很实用的例子。 （用在监控业务指标上很合适，比单纯的阈值监控好用，因为某些指标可能在周末或者凌晨是低峰期，单纯阈值告警可能有遗漏情况发生） Prometheus returns incorrect data when using offset queries I'm querying metrics with offset and it looks like it's not working as expected.
