I made the openshift monitoring instance with ManageIQ. The connection to openshift is succeeded.
But refreshing the openshift monitoring does not work. The openshift variables show nothing on the dash board. These are the evm.log of ManageIQ logs.

It seems that worker, which takes care of refreshing, is not starting at all due to the insufficient resources on Manage IQ server. If your swap is more than 60% full (seen from the log) then the services already used all of your RAM.
