# 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](http://doc.ntp.org/current-stable/ntpq.html). ## Requirements - Version: `NTPv4` - Local interrogation allowed in `/etc/ntp.conf` (default): ``` # Local users may interrogate the ntp server more closely. restrict 127.0.0.1 restrict ::1 ``` It produces: 1. system - offset - jitter - frequency - delay - dispersion - stratum - tc - precision 2. peers - offset - delay - dispersion - jitter - rootdelay - rootdispersion - stratum - hmode - pmode - hpoll - ppoll - precision ## Configuration Edit the `python.d/ntpd.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/ntpd.conf ``` Sample: ```yaml update_every: 10 host: 'localhost' port: '123' show_peers: yes # hide peers with source address in ranges 127.0.0.0/8 and 192.168.0.0/16 peer_filter: '(127\..*)|(192\.168\..*)' # check for new/changed peers every 60 updates peer_rescan: 60 ``` Sample (multiple jobs): Note: `ntp.conf` on the host `otherhost` must be configured to allow queries from our local host by including a line like `restrict nomodify notrap nopeer`. ```yaml local: host: 'localhost' otherhost: host: 'otherhost' ``` If no configuration is given, module will attempt to connect to `ntpd` on `::1:123` or `127.0.0.1:123` and show charts for the systemvars. Use `show_peers: yes` to also show the charts for configured peers. Local peers in the range `127.0.0.0/8` are hidden by default, use `peer_filter: ''` to show all peers. --- [](<>)
