I tried to parse nmap log using logstash . but logstash stopped with below error message

> [2017-07-06T06:10:19,811][ERROR][logstash.agent] Cannot create pipeline {:reason=\>"Couldn't find any codec plugin named 'nmap'. Are you sure this is correct? Trying to load the nmap codec plugin resulted in this error: Problems loading the requested plugin named nmap of type codec. Error: NameError NameError"}

Config:

```
input {
  http {
    host => "127.0.0.1"
    port => 8000
    codec => nmap
  }
}

output {
  stdout {
    codec => rubydebug
  }
}

```

Logstash Version : 5.4.1  
OS : CentOS 7
