Hi@akhtar,

You can use the filter plugin in Logstash. It will help you to retrieve particular data. There are lots of inbuilt Regex available. To find the IP address, IP Regex is available. I have attached one example below.

filter {
  grok {
  match => [ "message", "%{IP:myclientIP}" ]
  }
}

I hope this will help you.
