Hello @tharu85
Filebeat does not support to send same data to multiple logstash server simultaneously . To achieve this you have to start multiple instances of Filebeat with different logstash server configuration. This is the limitation of Filebeat output plugin
To start multiple instances of filebeat in same host, you can refer the below link
