# OpenNTPD Input Plugin
Get standard NTP query metrics from OpenNTPD ([OpenNTPD - a FREE, easy to use
implementation of the Network Time Protocol](http://www.openntpd.org/)).
Get standard NTP query metrics from [OpenNTPD][] using the ntpctl command.

Below is the documentation of the various headers returned from the NTP query
command when running `ntpctl -s peers`.

### Configuration:
### Configuration
```toml
# Get standard NTP query metrics, requires ntpctls executable
# provided by openntpd packages
[[inputs.openntpd]]
## If running as a restricted user you can prepend sudo for additional access:
#use_sudo = false
## Run ntpctl binary with sudo.
# use_sudo = false
## The default location of the ntpctl binary can be overridden with:
binary = "/usr/sbin/ntpctl"
## Location of the ntpctl binary.
# binary = "/usr/sbin/ntpctl"
## The default timeout of 1000ms can be overriden with (in milliseconds):
#timeout = 1000
## Maximum time the ntpctl binary is allowed to run.
# timeout = "5ms"
```
### Measurements & Fields:
### Metrics
- ntpctl
- delay (float, milliseconds)
- jitter (float, milliseconds)
- offset (float, milliseconds)
- poll (int, seconds)
- next (int,,seconds)
- wt (int)
- tl (int)
- tags:
- remote
- stratum
- fields:
- delay (float, milliseconds)
- jitter (float, milliseconds)
- offset (float, milliseconds)
- poll (int, seconds)
- next (int, seconds)
- wt (int)
- tl (int)
### Tags:
- All measurements have the following tags:
- remote
- stratum
### Permissions:
### Permissions
It's important to note that this plugin references ntpctl, which may require
additional permissions to execute successfully.

You will also need to update your sudoers file:
```bash
$ visudo
# Add the following line:
telegraf ALL=(ALL) NOPASSWD: /usr/sbin/ntpctl
# Add the following lines:
Cmnd_Alias NTPCTL = /usr/sbin/ntpctl
telegraf ALL=(ALL) NOPASSWD: NTPCTL
Defaults!NTPCTL !logfile, !syslog, !pam_session
```
Please use the solution you see as most appropriate.
