Logstash drop filter plugin

Elastic Stack Logstash
1

As we know, we can drop like that:
if [log][file][path] == "/var/log/messages" {
drop {}
}
But I have case when I am getting logs in format "/var/log/messages-20221212" or "/var/log/messages-date"

But logstash drop filter plugin is not understanding:
if [log][file][path] == "/var/log/messages-*" {
drop {}
}
Can anyone help me?
Thanks

Try with:

if ( [log][file][path] =~ /^\/var\/log\/messages-\d+/)  {
  drop {}
}

You can also use without \d+ at the end in case you don't want a number validation, at the end.
