This collector monitors NSD statistics like queries, zones, protocols, query types and more.

setup:
prerequisites:
list:
- title: NSD version
description: |
The version of `nsd` must be 4.0+.
- title: Provide Netdata the permissions to run the command
description: |
Netdata must have permissions to run the `nsd-control stats_noreset` command.
You can:
- Add "netdata" user to "nsd" group:
```
usermod -aG nsd netdata
```
- Add Netdata to sudoers
1. Edit the sudoers file:
```
visudo -f /etc/sudoers.d/netdata
```
2. Add the entry:
```
Defaults:netdata !requiretty
netdata ALL=(ALL) NOPASSWD: /usr/sbin/nsd-control stats_noreset
```
> Note that you will need to set the `command` option to `sudo /usr/sbin/nsd-control stats_noreset` if you use this method.
configuration:
file:
name: "python.d/nsd.conf"
options:
description: |
This particular collector does not need further configuration to work if permissions are satisfied, but you can always customize it's data collection behavior.
There are 2 sections:
* Global variables
* One or more JOBS that can define multiple different instances to monitor.
The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.
Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.
Every configuration JOB starts with a `job_name` value which will appear in the dashboard, unless a `name` parameter is specified.

Job name. This value will overwrite the `job_name` value. JOBS with the same name are mutually exclusive. Only one of them will be allowed
