Computing average request time with mvcount fields and numerical field values

Hello,

Is it possible to compute an average of the numerical field by dividing it by the mvcount field I am defining?

I have a field foo whose value is numeric. I have another field bar_count whose value is numeric and is the mvcount of a multivalue field.

For each event, I want to chart the average:

... | chart eval(foo/bar_count) as average_tran

You can either:

... | eval f=foo/bar_count | chart first(f) as average_tran

or

... | chart first(eval(foo/bar_count)) as average_tran

You need an aggregator with chart (in this case, first()) as it must be told how to resolve the possibility of multiple values.

I do question why you are charting what will come out as a single value here though, but I assume that you're simplifying somewhat and that your real chart command has a split-by field. Otherwise, you can really just skip the chart command entirely.
