Chapter 1 What’s New for FortiOS 5.0 : New features in FortiOS 5.0 Patch 6 : Endpoint Control Daemon Improvement
  
Endpoint Control Daemon Improvement
Endpoint Control has been improved in several ways:
For FortiGate models 3000 and higher, the maximum limit of FortiClient registration licence has been increased from 8000 to 16000.
The intervals between KeepAlive messages are now configurable on the FortiGate unit, so that the interval value can be adjusted to get a trade-off between accuracy and the FortiGate workload. This value can be configured in the CLI:
set forticlient-keepalive-interval <interval> (interval measured in seconds).
The intervals between two system update messages can be configured through the CLI:
set forticlient-sys-update-interval <interval> (interval measured in minutes).
KeepAlive timestamps are now be stored use a in-memory avl tree structure, in order to decrease the number of CMDB savings.
A mixed TCP/UDP mechanism now handles the registration sync.
FortiClient registration information is stored using a hard disk instead of flash disk.
