The output variables are specific to the model used in your inputs. To see all available reports add this to your input file:
Output:VariableDictionary, IDF;
Then run your simulation and find the eplusout.rdd (report data dictionary) file. Choose the report from those available and copy-n-paste directly into your input file.
A few examples from the beginning of this file are:
