BlueCat Address Manager

The DHCP Heat Map displays a calendar view of yearly DHCP leases (up to a maximum of five years of DHCP lease data). This provides daily DHCP lease distribution data which can help you track the patterns and device types to which IP addresses were assigned.

Ensure that you have first performed the collecting data task.

The DHCP Heat Map provides a visual representation of DHCP leases and device types on a daily basis, including historical DHCP leases over multiple years. Depending on the data currently in your database, up to a maximum of five years of DHCP lease data will be displayed.

  • The density of the color for each date box on the calendar map represents a qualitative view of your data. That means different colors don't show any fixed quantity of DHCP lease amount. For example, if you are comparing a dark blue-colored date box with light blue-colored date box, this only means that the dark blue-colored date box has more DHCP leases on that particular date, compared to the light blue-colored date.
  • The Lease Number legend table displays different color schemes in use and the maximum number of DHCP leases for that color.
  • Each cell represents a day.
  • Different color schemes for cells present number of leases per day.
