How to: View Server and Service Logs

From the Logs page in NodeWorx, Server Administrators are able to view server and service-level log files.

Domain-level logging can be viewed from within SiteWorx. Details can be found here.

While InterWorx does provide this user interface, it is generally recommended to view and manage log files from the CLI, as that provides an improved ability to search for specific entries, as well as view logging in real time while reproducing issues during troubleshooting.
