Monitors the leases database to show all active leases for given pools.

• dhcpd leases file MUST BE readable by Netdata
• pools MUST BE in CIDR format
• python-ipaddress package is needed in Python2

It produces:

1. Pools utilization Aggregate chart for all pools.

   • utilization in percent

2. Total leases

   • leases (overall number of leases for all pools)

3. Active leases for every pools

   • leases (number of active leases in pool)

Edit the python.d/isc_dhcpd.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/isc_dhcpd.conf

Sample:

local:
  leases_path: '/var/lib/dhcp/dhcpd.leases'
  pools:
    office:         '192.168.2.0/24'                            # name(dimension): pool in CIDR format
    wifi:           '192.168.3.10-192.168.3.20'                 # name(dimension): pool in IP Range format
    192.168.4.0/24: '192.168.4.0/24'                            # name(dimension): pool in CIDR format
    wifi-guest:     '192.168.5.0/24 192.168.6.10-192.168.6.20'  # name(dimension): pool in CIDR + IP Range format

The module will not work If no configuration is given.
