In my logstash filter, I received following filed and its value.. In order to remove duplicate filed value, first I need to remove special characters in that filed value.
For given sample the field name "log_name" listed two results and they are duplicated values, but followed with special characters. "Authentication," and "Authentication;"
So Need a help to remove special characters in the filed value (, and ; ) -> comma and colon
"log_name" => [
[0] "Authentication,",
[1] "Authentication;"
],
