A question about getting data in

[hnu20123501025]

I installed the Java SE 7/ Mongo DB version 3.0.5/ Apache Maven 3.3.3 in Mac os. I also run the program successfully. When I run sudo ./server.sh
The result is below. It seems right.

Unfortunately, I do not know how to find the collected information in MongoDB. Because I have seen
"2016-03-22T22:56:25.050+0800 I FTDC [initandlisten] Initializing full-time diagnostic data capture with directory '/data/db/diagnostic.data' ", I searched the "data/db/diagnostic.data". In this file, I can see the file named like this "metrics.2016-03-22T14-56-26Z-00000".
So do you know how can I do now.

Thank you very much.
Best Regards.
