Running Graylog on Mac OS X 10.14.4. Previously ran 2.5.1 with the collector configured to use nxlog. Recently upgraded to Graylog 3.0 and have been unable to figure out how to configure the Sidecar for a Darwin collector (nxlog). The OS choices are Linux and Windows. I can set up a Linux collector but when I try to assign it to the Sidecar, it informs me that there are no Darwin collectors available. I currently have the Legacy collector running, but would rather switch to the current technology. Anyone have any advice? Is it possible?
