title: "NTP daemon monitoring with Netdata"

# 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.
