Aug 16, 2017 · I was trying to create a Prometheus graph on Grafana, but i can't find the function which calculate the average value. For example , to create a graph for read_latency, the result contain many tags. If there are 3 machine, there will be 3 tag seperately, for machine1, machine2, machine3.

The following functions allow aggregating each series of a given range vector over time and return an instant vector with per-series aggregation results: avg_over_time(range-vector): the average value of all points in the specified interval. min_over_time(range-vector): the minimum value of all points in the specified interval.

Refer to the following list of calculations you can perform in Grafana. You can find these calculations in the Transform tab and in the bar gauge, gauge, and ...

05.05.2015 · Since the avg, min, max are calculated by grafana after graphite does consolidation to (maxDataPoints) it they will not be correct. They will be correct for the points drawn on the graph but not for the real underlying data in the series. By the default graphite will average points when consolidating (can by changed by consolidateBy). So the

Grafana displays the Identifier field, followed by the fields returned by your query. You can apply filters in one of two ways: Enter a regex expression. Click a field to toggle filtering on that field. Filtered fields are displayed with dark gray text, unfiltered fields have white text. In the example below, I removed the Min field from the results.

Supported function for operating over unwrapped ranges are: rate(unwrapped-range): calculates per second rate of all values in the specified interval. sum_over_time(unwrapped-range): the sum of all values in the specified interval. avg_over_time(unwrapped-range): the average value of all points in the specified interval.

Hi. I'm having a value sum(power_watts{job="powerdc"}) which gives me a power usage of some devices. What I want is the an average per ...

Grafana only calculates averages and such based on the data returned from a datasource so only from the selected time range. Usually time series ...

This function can be used with aggregation functions average(or avg), avg_zero, median, sum(or total), min, max, diff, stddev, count, range(or rangeOf) , multiply& last(or current). aggregateWithWildcards(seriesList, func, *positions)¶ Call aggregator after inserting wildcards at the given position(s).
