Graphite how to summarize based on selected interval

Question

How can I summarize graphite data depending on the selected interval? If the selected interval is up to 1 hour, the data counter should show data points for every minute. If the interval is up to 3 hours, the data should be summarized over 5 minutes. If the interval is up to 1 day, the data should be summarized over 15 minutes.

Is this possible?

Solution 1

AFAIK Graphite doesn't do this automatically.

However since Graphite has a public API you can script this yourself automatically to retrieve the graph with the correct summarizing period. Grafana for example does this when using the 'auto' option for interval template.

Pseudo-code:

if interval == '1h':
    get_metric(summarize(metric, '1min', 'sum')
elif interval == '3h':
    get_metric(summarize(metric, '5min', 'sum')
elif interval == '1d':
    get_metric(summarize(metric, '15min', 'sum')

Solution 2

You can get something close this this using by creating an interval template variable, enable the Auto option, and set number of steps. In the example below it's set to 40 steps so it will pick an appropriate interval based on the time range.

Use the variable like this:
