To check the maximum allowed bandwidth and current traffic size, do the following:

1. Check the Maximum bandwidth capacity allowed through Administration > License.
2. Check the network traffic size Deep Discovery Inspector monitors using the Dashboard.
   1. Go to Dashboard, add a new tab, or select one of existing tab.
   2. Click Add Widgets, find Monitored Network Traffic in Past 30 Days widget from the list, and then click Add.
       

      A red line appears to indicate the maximum bandwidth capacity.

       

   If DDI has exceeded the maximum bandwidth capacity frequently, consider to do the following.

   • Narrow down the traffic DDI monitors.
   • Filter traffic on the mirroring device, or divide network segments, then transfer the traffic only DDI should monitor, etc.
   • Add more DDI devices
   • Replace DDI with a high-end model
