Merge two disjunct number fields into one

[mhornste]

Hi,

I had to switch from one DB Connect App to another which leads to two fields where I have my version information:

AverageVersions2
AverageVersions

both fields are disjunct regarding the data in it meaning that intil 10th of August, AverageVersions has data, after that AverageVersions2 has data.

I now want to display the data in my graph showing all values. I tried the following without success:
index=otcs sourcetype=OtcsAvgVersions | rename AverageVersions2 as output | rename AverageVersions as output | table _time output| reverse

The problem is: the data from AverageVersions from 11th of August is not displayed.

Can anyone help please?

The eval coalesce function may be of use here, as the documentation states the function takes an arbitrary number of arguments and returns the first value that is not null. Maybe something like:

index=otcs sourcetype=OtcsAvgVersions | eval output=coalesce(AverageVersions2,AverageVersions) | table _time output | reverse
