This is a plugin for Logentries and Logstash.
You can forward logs from Logstash to Logentries using unique token. To do this you have to configure the output sectin of your .conf file in your logstash main folder.
output { logentries{ token => "LOGENTRIES_TOKEN" } }
Please refer to this [blog](link here) for more information and instruction on how to set up your .config file.
You can find the instructions about Token based input here
Try #logstash on freenode IRC or the logstash-users@googlegroups.com mailing
