# ISC DHCP monitoring with Netdata Monitors the leases database to show all active leases for given pools. ## Requirements - 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) ## Configuration Edit the `python.d/isc_dhcpd.conf` configuration file using `edit-config` from the Netdata [config directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`. ```bash cd /etc/netdata # Replace this path with your Netdata config directory, if different sudo ./edit-config python.d/isc_dhcpd.conf ``` Sample: ```yaml 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. --- [](<>)
