In the Prometheus histogram metric as configured above, almost all observations, and therefore also the 95th percentile, will fall into the bucket labeled {le="0.3"}, i.e. the bucket from 200ms to 300ms. The histogram implementation guarantees that the true 95th percentile is somewhere between 200ms and 300ms. See more First of all, check the library support forhistograms andsummaries. Some libraries support only one of the two types, or they support summariesonly in a limited fashion (lacking quantile calculation). See more A straight-forward use of histograms (but not summaries) is to countobservations falling into particular buckets of observationvalues. You might have an SLO to serve 95% of … See more Histograms and summaries both sample observations, typically requestdurations or response sizes. They track the number of observationsand the sum of the observed values, allowing you to calculate theaverage of the … See more You can use both summaries and histograms to calculate so-called φ-quantiles,where 0 ≤ φ ≤ 1. The φ-quantile is the observation value that ranks at numberφ*N among … See more WebApr 3, 2024 · Bucket中分布的样本值个数,命名为_ Bucket {Le "< upper boundary >"}。解释更容易理解。该值表示索引值小于等于上边界所有样本的个数。 3.2）所有样本值大小的总和,命名为_sum。 取值可以理解为数据指标值字段的划分。划分依据应基于数据值的分布。

WebThis is the Prometheus query expression we're going to use: sum by (le) (rate (duration_post_with_retry_seconds_bucket [30s])) Woof, there's a lot to it! Let's take this slow. It's worth understanding every single bit of this. We added the suffix _bucket. That is using a Prometheus naming convention to get to the per-bucket time series data. WebJan 14, 2024 · Note that the metric name in the code may be a substring of the final metric name, as a namespace may be prepended to it (the prometheus_ part in my example above) and for histograms and summaries _count or bucket or something else may be appended. nba playoffs television coverage
