The following table describes the host statistics listed on the Statistics page.

If your FireSIGHT System deployment includes a Defense Center with a FireSIGHT license, you can 
also view statistics about the Data Correlator and network discovery processes for the current day. As 
the managed devices perform data acquisition, decoding, and analysis, the network discovery process 
correlates the data with the fingerprint and vulnerability databases, then produces binary files that are 
processed by the Data Correlator running on the Defense Center. The Data Correlator analyzes the 
information from the binary files, generates events, and creates the discovery network map.

The statistics that appear for network discovery and the Data Correlator are averages for the current day, 
using statistics gathered between 12:00 AM and 11:59 PM for each device. 

The following table describes the statistics displayed for the Data Correlator process.
