Logstash

The logformat option will output logs in Logstash (JSON) format.

Common practice is to run curator as a cron job, e.g.

20 0 * * * /usr/local/bin/curator --logformat logstash <<command>> <<flags>> 2>&1 | /bin/nc localhost 28778

Then Logstash can be configured using:

input {
  tcp {
    codec => json
    type => "curator"
    port => "28778"
  }
}
