Hi @karthi2809 ,

you can use this regex:

| rex field=source "^\/\w+\/\w+\/(?<environment>\w+)\/\w+-(?<component>[^-]+)-(?<filename>.*)"

you can test this regex at https://regex101.com/r/0VJvAw/1

Ciao.

<your_search>|rex field=source "\/audit\/logs\/(?<environment>[^\/]*)\/(?<hostname>[^-]*)\-(?<component>[^-]*)\-(?<filename>.*$)"
