Dnsmasq DHCP monitoring with Netdata
Dnsmasq is a lightweight, easy to configure, DNS forwarder and DHCP server.
This module monitors Dnsmasq DHCP leases database.
Charts
It produces the following set of charts for every dhcp-range:
- DHCP Range Allocated Leases in
leases - DHCP Range Utilization in
percentage
Auto-detection
Module automatically detects all configured dhcp-ranges reading dnsmasq configuration files.
By default it uses:
/var/lib/misc/dnsmasq.leasesto read leases./etc/dnsmasq.confto detect dhcp-ranges./etc/dnsmasq.dto find additional configurations.
Configuration
Edit the go.d/dnsmasq_dhcp.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
sudo ./edit-config go.d/dnsmasq_dhcp.conf
Here is an example:
jobs:
- name : dnsmasq_dhcp
leases_path : /var/lib/misc/dnsmasq.leases
conf_path : /etc/dnsmasq.conf
conf_dir : /etc/dnsmasq.d
For all available options please see module configuration file.
Troubleshooting
Check the module debug output. Run the following command as netdata user:
./go.d.plugin -d -m dnsmasq_dhcp
