Logstash how to send data from a file in a loop?

As part of load testing, I have a couple of premade log files that simulate different scenarios.

I'm trying to use Logstash to send the content of 1 file, and resend it again in a loop every time it reaches EOF.

Is there a way for me to do that?

better to use an input plugin, called file, so with this, Logstash will continuously read the log file from the beginning every time it reaches the end!

input {
  file {
    path => "/path/to/your/log/file.log"
    start_position => "beginning"
    sincedb_path => "/dev/null"
    mode => "read"
    file_completed_action => "delete"
    file_completed_log_path => "/path/to/completed/log/file.log"
    sincedb_clean_after => "0"
    close_older => "0"
    stat_interval => "1"
    discover_interval => "1"
  }
}

output {
  # Output configuration
}

update

by setting file_completed_action to "logstash_forward",your file will be sent again to Logstash when it reaches the end!

input {
  file {
    path => "/path/to/your/log/file.log"
    start_position => "beginning"
    sincedb_path => "/dev/null"
    mode => "read"
    file_completed_action => "logstash_forward"
    file_completed_log_path => "/path/to/completed/log/file.log"
    sincedb_clean_after => "0"
    close_older => "0"
    stat_interval => "1"
    discover_interval => "1"
  }
}
