1) On ClearGLASS dashboard, add your OpenShift cartridge as 'Other server' in order to receive a uuid/password pair. Check out http://docs.ClearGLASS/article/28-adding-other-servers for more info. You can simple provide a title, or can also provide an ip address.
Enable monitoring on this, so that you get a command with uuid/password. Copy this
the first string is the uuid (18db26b16c398c234fd4c4f27f16a25d) while the second one is the password (b48dfbd90d1d946)
