I tried doing it with the only translate it did not work.So I added grok to check my luck. Can you please suggest something
input {
file {
path => "C:/Users/kumar/Desktop/grok.csv"
start_position => "beginning"
sincedb_path => "NULL"
}
}
filter {
csv {
separator => ","
columns => ["Name","Age","System"]
}
translate {
field => "System"
destination => "realOS"
fall_back => "not_found"
dictionary => ["Windows10","Kali","Ubuntu","CentOS"]
}
grok {
match => { "field" => ["%{WORD:System}"]}
}
}
output {
elasticsearch{
hosts => "http://localhost:9200/"
index => "grok"
}
stdout{}
