Hi,
I have a csv filter which generates the fields. I want to check all the generated fields (whether all the characters are numbers), if then mutate those fields to Integer.

Hi Magnus
Thanks for the reply. But I am aware of the convert option in CSV filter. But my question is more of auto-identifying the eligible fields for conversion to integer. Say I have a CSV with nearly 100 fields with a mix of string and number fields. Is there any generic conditional(like the following) in logstash to run through all those fields and identify number fields.
if [ field] =~ /.^/\d$./{
CSV(or mutate)
{
Convert => { [field] => "integer" }
}
}
Hope you got my question this time
Thanks
Bharath
Currently you need to write a small piece of Ruby in a ruby filter to accomplish this, but it's reasonable for the csv filter to guess the data type of the columns. I created a GitHub issue for this feature request.
