Redis Logstash Filter

redis.logstash.filter.rb

input {
  file {
    path => "/var/log/redis/redis-server.log"
    start_position => "beginning"
    type => "redis"
    add_field => { "role" => "redis" }
  }
}
filter {
  if [type] == "redis" {
    grok {
      pattern =>  [ "%{POSINT:redis_pid}:[A-Z] %{MONTHDAY} %{MONTH} %{HOUR}:%{MINUTE}:%{SECOND} \* %{GREEDYDATA:redis_message}" ]
    }
    mutate {
      remove_field => "message"
    }
    mutate {
      rename => [ "redis_message", "message" ]
    }
  }
}

Newer versions seem to include the year, also some messages have a # instead of a *

%{POSINT:redis_pid}:[A-Z] %{MONTHDAY} %{MONTH} %{YEAR} %{HOUR}:%{MINUTE}:%{SECOND} [#*] %{GREEDYDATA:log_message}
