17.08.2017 · Hello, i just join the Grafana community to ask some help for a specific need on Grafana graph. I use grafana connected to an open-TSDB base for Capacity Planning purpose I have several (32) servers with their CPU usage graph. What i want to see is the average CPU usage of all these servers agregated in only one graph. I don’t find the manner to build this graph. First …

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

Functions Variables

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.

$__range_series - invoke function over all series values. Examples: groupBy($__range, avg) percentile($__range_series, 95) - 95th percentile ...

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.
