+# 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 <IP> 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.
