is there any way to break if conditions ?
filter {
     grok {
           patterns_dir => "/etc/logstash/file/patterns"
           match => { "message" => "%{COMMON_HEADER}" }
          }   
   if "_grokparsefailure" in [tags] {
          ... break and go to output {}
   } else {
          add_tag => [ "parsed" ]
          ... continue if statement ...
          if {
             if {
              }
          }
          ... go to output {}
}
