At some point, you will need to see what is happening on the server side. Maybe your application is failing to deploy, or you need to see the logs after you encounter an error. There are a few ways you can view the OpenShift server logs:
Tail the logfile using client tools
Run SSH into the gear
Tailing the application server log is simple. You just need to run the rhc tail command. For example, to view the log for the example application that we called wildfly, you need to execute the following:
$ rhc tail -a wildfly
This will print out the latest entries from the logfile, as follows:
