Range vector literals work like instant vector literals, except that they select a range of samples back from the current instant. Syntactically, a time duration is appended in square brackets ( [] ) at the end of a vector selector to specify how far back in time values should be fetched for each resulting range vector element.

In Prometheus's expression language, an expression or sub-expression can evaluate to one of four types: Instant vector - a set of time series containing a single sample for each time series, all sharing the same timestamp Range vector - a set of time series containing a range of data points over time for each time series

Range vector seems more logical as it has values per timestamp : range vectors works between a range of 2 timestamps, so when you apply the [5m] ...

09.06.2021 · The above table shows how vector and matrix result types can represent different things, depending on the endpoint and the type of the input PromQL expression. These formats are a bit general in nature and will appear …

The instant vector and range vector are two of four types of expression language; the final two are scalar, a simple numeric floating point ...

Mar 15, 2019 · A range-vector is typically generated in order to then apply a function to it to get an instant-vector, which can be graphed (only instant vectors can be graphed). Prometheus has many functions for both instant and range vectors. The more commonly used functions for working with range-vectors are:

What’s A vector?

Jul 02, 2021 · Instant query: when you query Prometheus for result of an expression on a single timestamp. e.g. for alerting. Range query: when you query Prometheus for an expression with start and end timestamps. e.g. for graphing in Grafana. So your expression can have a number of instant and range vectors in it, and be sent to Prometheus as an instant or ...

PromQL is a powerful, concise querying language for Prometheus. ... PromQL uses three data types: scalars, range vectors, and instant ...

Jul 02, 2020 · Today, let's look a bit closer at the two ways of selecting data in PromQL: instant vector selectors and range vector selectors. We will examine their use cases, the reasoning behind them, and some implementation details you should be aware of. Selecting data from Prometheus's TSDB forms the basis of almost any useful PromQL query before ...

A instant vector (or vector) might be: metric{foo="bar"} 3.0. metric{foo="baz"} 9.7. A range vector might be: metric{foo="bar"} [email protected] [email protected] metric{foo="baz"} [email protected] [email protected] Note that the timestamps (the numbers after the @) don't have to match up across a range vector.

PromQL is a built in query-language made for Prometheus. ... Since only Instant Vectors can be graphed, they take a Range Vector as a parameter and return a ...
