NTP daemon monitoring with Netdata
Monitors the system variables of the local ntpd daemon (optional incl. variables of the polled peers) using the NTP
Control Message Protocol via UDP socket, similar to ntpq,
the standard NTP query program.
Metrics
All metrics have "ntpd." prefix.
Labels per scope:
- global: no labels.
- peer: peer_address.

Configuration
Edit the go.d/ntpd.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 go.d/ntpd.conf
Configuration example:
jobs:
- name: local
address: '127.0.0.1:123'
collect_peers: no
- name: remote
address: '203.0.113.0:123'
timeout: 3
collect_peers: no
For all available options please see
module configuration file.
Troubleshooting
To troubleshoot issues with the ntpd collector, run the go.d.plugin with the debug option enabled. The
output should give you clues as to why the collector isn't working.
-
Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on
your system, open netdata.conf and look for the plugins setting under [directories].
cd /usr/libexec/netdata/plugins.d/
-
Switch to the netdata user.
sudo -u netdata -s
-
Run the go.d.plugin to debug the collector:
./go.d.plugin -d -m ntpd
