https://www.eclipse.org/che/docs/che-7/tracing-che/ has a number of environment variables to set to enable tracing.
Is it possible to set these when working on OpenShift? If so; where would the correct place be; and where will the Jaeger interface be available?
Thanks

Yes, you can configure it for the Che master of your installation.
OpenShift is the Saas Che offering
As a user of che.openshift.io you can't leverage from tracing capabilities of Che at this moment.
