This should never show more records than the given k.If you are only wanting to see the history of the current topk, use the table view to grab the currents and then query not for the topk but for just those k records.Note also you could handle the "rest" in a similar way via negated regexp.Since it hasn't been mentioned, even though it is an additional component, Grafana can do this quite easily as well.

Thanks again for this amazing product.


However the use cases for this generally turn out to be averaging of either averages or quantiles, neither of which are statistically valid.that is sum and then divide. Guess we could look at the labels or something if the value is the same.we can let user specify another time-range parameter (for example use last 5m to determine topK and show a 1day graph) / or even queries, use to determine the resulting timeseries to show on the graph.That would at each point display the top 5 metrics based on the average over the last 5m. And since the top 5 changes over time, there can be more than 5 values.For those running into this and finding this, for me this was resolved by checking the "Instant" checkbox in the metric query row.Successfully merging a pull request may close this issue.Prometheus topk and sort_desc provides additional metrics.You signed in with another tab or window. What end users are saying about Grafana, Cortex, Loki, and more. Related. topk: 如查询2的值：topk(2, logback_events_total) 5. irate: 如查询过去5分钟的平均值: irate( logback_events_total[5m]) 配置. In general, always do division last.Relatedly if a NaN manages to get into the input of a function or operator that does math on values the result will be NaN. All calculations in Prometheus are floating point operations. Prometheus depicted in a sculpture by Nicolas-Sébastien Adam, 1762 (). Legend format: Controls the name of the time series, using name or pattern. The query_range API endpoint in Prometheus which is used for graphing evaluates each step independently, so a graph like topk(5, node_scrape_collector_duration_seconds) can display far more than 5 time series.

Some monitoring systems use NaN as a null or missing value, however in Prometheus NaN is just another floating point value. 启动时，可以加载运行参数-config.file指定配置文件， 默认为prometheus.yml: 在该配置文件中可以指定各种属性，其结构体定义如下： For example {{hostname}} is replaced with the label value for the label hostname.
