How many free IP-Addresses are available in the DHCP Pool

Hello, is it possible to get information from the Fortigate that there are no or only very few IP addresses available from the interface's DHCP pool. FortiAnalyzer or Syslog server is present.

You may also enable SNMP trap on Fortigate to get an alert when the dhcp pool usage is at 90%.

I will add to akristof's reply that there's also events 26005 (LOG_ID_DHCP_LEASE_USAGE_HIGH) and 26006 (LOG_ID_DHCP_LEASE_USAGE_FULL) to signal that the pool utilisation is high, or exhausted, respectively.

You can use these events as triggers in automation stitches, to send an email/IM notification, etc.
