Centos7 system，graylog、elasticsearch、mongod、sidecar、filebeat all installed and running good.
I want to send /var/log/*.log these local log file with filebeat to localhost：5044
If I create a collection configuration and just add a name ，don’t change anything else。
then ，sidecar-administration-shows——running【status is green】，graylog didn’t get any logs。
But If I change the configuration：hosts:[“localhost:5044”]
then sidecar-administration-shows——red ! Failing -collector configuration file is not valid，waiting for the next update （all I have done is change that host ip address）
and there is a strange thing—— I had to move four cursor to right or i can’t input string
s in the right place——the cursor’s location is not where i see it!
