This is my log sample that all lines are starting with follow :
134.255.248.30 - - [01/May/2024:13:54:53 +0330]
I want to use multiline pattern in my filebeat.yml file so I used follow syntax
parsers:
- multiline:
type: pattern
pattern: ^([\d.]{3,17} - - [[\d/:]{1,4}[A-Z]{1,3}[a-z/]{1,5}[\d:]{1,20})
negate: true
match: after
