Hi

I am getting the below errors while parsing using CSV filter

CSV filter

if [filename]{
csv { source => "filename"
separator => ","
columns => ["[docname1]","[docname2]"]
#target => "docname1"
}
}

Your filename field is an Array and not a String, as noted by the errors. Can you post a sample input line?

yes. It is an array. I have changed the filtering as below and it worked. Thanks.

csv {
source => "[filename][0]"
separator => ","
columns => ["[docname]","[docname1]"]
#skip_empty_rows => true
skip_empty_columns => true
}
