Hi,

first thanks for this awesome software. But I have some trouble and I don't know how to proceed. First I try to find out what else I could provide for this report to be a good bug report.

First, I use the latest version (v1.14.0) from openSUSE build Service. I know, I should compile it by my self to avoid any other causes for this behavior. But for now I still use this package from there

[location]: Line 98
[problem]: printf("presss any key to exit\n");

[expect]: someone can fix this and submit a pr.

[[outputs.graylog]]
