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

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 your agent's 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 : '192.168.3.0/24 192.168.4.0/24 192.168.5.0/24'

In case of python2 you need to install py2-ipaddress to make plugin work. The module will not work If no configuration is given.
