This plugin gathers stats from NSD - an authoritative DNS name server.
# A plugin to collect stats from the NSD DNS resolver [[inputs.nsd]] ## Address of server to connect to, optionally ':port'. Defaults to the ## address in the nsd config file. server = "127.0.0.1:8953" ## If running as a restricted user you can prepend sudo for additional access: # use_sudo = false ## The default location of the nsd-control binary can be overridden with: # binary = "/usr/sbin/nsd-control" ## The default location of the nsd config file can be overridden with: # config_file = "/etc/nsd/nsd.conf" ## The default timeout of 1s can be overridden with: # timeout = "1s"
It’s important to note that this plugin references nsd-control, which may require additional permissions to execute successfully. Depending on the user/group permissions of the user executing this plugin, you may need to alter the group membership, set facls, or use sudo.
Group membership (Recommended)
$ groups cua cua : cua $ usermod -a -G nsd cua $ groups cua cua : cua nsd
If you use this method, you will need the following in your config:
[[inputs.nsd]] use_sudo = true
You will also need to update your sudoers file:
$ visudo # Add the following line: Cmnd_Alias NSDCONTROLCTL = /usr/sbin/nsd-control cua ALL=(ALL) NOPASSWD: NSDCONTROLCTL Defaults!NSDCONTROLCTL !logfile, !syslog, !pam_session
Please use the solution you see as most appropriate.
