I'm trying to move fields from multi value fields using mvindex. Currently under "time" field I have only 3 values so i am easily moving them as new field. Is there anyway to automate this process without hard coding it?

time = 9:30
10:30
11:30
Currently I am doing this
| eval first.time=mvindex(time, 1), second.time=mvindex(time, 2), third.time=mvindex(time, 3)

This will give me first.time = 9:30, second.time= 10:30, third.time=11:30 fields moved from time field where it is a multivalued field. If i have undefined number of fields under this what should I do to automate it? instead of hardcoding it like | eval first.time=mvindex(time, 1), second.time=mvindex(time, 2), third.time=mvindex(time, 3) fourth.time=mvindex(time,4)............hundred.time=mvindex(time,100)

Hi, @praneeth2050
It's a boring name, but it works.

What is the problem are you trying to solve? Creating many fields like this is rarely a good idea.

So, I am trying to create a Splunk report with the changes in time and changes in other fields. The data I receive will have multiple time fields. For now i have only 3 time fields. In the future, I may even have 10 or 20-time fields... In the case of hardcoding using mvindex is there any alternative?

PS: I have extracted this multivalued field using REGEX
