Hi,

We had the same problem - as RHEL 5.x is not supported by the Go language anymore the Beats won't work. You need at least RHEL 6.x: https://www.elastic.co/de/support/matrix

If for any reason you have to still work with RHEL 5.x you might want to check out LogStash and its file-input.

Best regards
Wolfram

thanks,but if i start up filebeat 6.2.3.It can work. Just the version 6.6.1,it is not worked!

I guess this is because Beats 6.3 upgraded go to version 1.9.4: https://www.elastic.co/guide/en/beats/libbeat/current/release-notes-6.3.0.html#_added_8
