Hi,

I want to run command "ssh ip -c ls" every 1 hour in logstash exec input plugin. If i have 3 logstash nodes in cluster every logstash nodes will execute this ? if yes how do i set only one logstash node execute the command at a time.

Example: 3 logstash nodes has same execute command and same schedule but any one server should execute.
