logstash 中缺少 grep 过滤器

Question

我正在尝试使用 grep 函数，但它不起作用，

这是错误：

Couldn't find any filter plugin named 'grep'. Are you sure this is correct?    
Trying to load the grep filter plugin resulted in this error: no such file to 
load -- logstash/filters/grep

这是我的文件logstash.conf

input {
stdin { }
file {
type => "FireWall"
path => "/var/log/test.txt"
start_position => 'beginning'
}
}
filter {


grep {

    match =>["message",".* Morito .*"]
 }
grok {

patterns_dir => "./patterns"
   match => [
    "message", "%{WORD:firstname} %{WORD:lastname} %{NUMBER:age}    
]
}
}
output {
stdout { }
elastic search {
cluster => "logstash"
}
}

请问我该怎么办？

grep{} 被弃用，取而代之的是条件语句和 drop{}:

if [message] =~ /regexp/ {
     drop{}
}
