You need to be running a replica set for the advanced stats.

To get the MongoDB stats you first need to enable the monitoring by following the installation instructions for Linux, Mac, FreeBSD and Windows.

Basic stats will be reported for single mongod servers and master/slave setups but for our advanced stats including our MongoDB dashboard, you need to be running in replica sets. The agent must be installed on each server you wish to monitor and appear on the dashboard and at the least, must be installed on the primary for each replica set.
