# BIND 9 Nameserver Input Plugin

This plugin collects metrics from [BIND 9 nameservers](https://www.isc.org/bind) using the XML or
JSON endpoint.

For _XML_, version 2 statistics (BIND 9.6 to 9.9) and version 3 statistics
(BIND 9.9+) are supported. Version 3 statistics are the default and only XML
format in BIND 9.10+.

> [!NOTE]
> For BIND 9.9 to support version 3 statistics, it must be built with the
> `--enable-newstats` compile flag, and the statistics must be specifically
> requested via the correct URL.

For _JSON_, version 1 statistics (BIND 9.10+) are supported. As of writing, some
distros still do not enable support for JSON statistics in their BIND packages.

**Introduced in:** Telegraf v1.11.0
**Tags:** server
**OS support:** all

[bind]: https://www.isc.org/bind

## Global configuration options <!-- @/docs/includes/plugin_config.md -->

Plugins support additional global and plugin configuration settings for tasks
such as modifying metrics, tags, and fields, creating aliases, and configuring
plugin ordering. See [CONFIGURATION.md](/telegraf/v1/configuration/#plugins) for more details.

[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins

## Configuration

```toml @sample.conf
# Read BIND nameserver XML statistics
[[inputs.bind]]
  ## An array of BIND XML statistics URI to gather stats.
  ## Default is "http://localhost:8053/xml/v3".
  # urls = ["http://localhost:8053/xml/v3"]
  # gather_memory_contexts = false
  # gather_views = false

  ## Report xml v3 counters as integers instead of unsigned for backward
  ## compatibility. Set this to false as soon as possible!
  ## Values are clipped if exceeding the integer range.
  # report_counters_as_int = true

  ## Timeout for http requests made by bind nameserver
  # timeout = "4s"
```

- **urls** []string: List of BIND statistics channel URLs to collect from.
  Do not include a trailing slash in the URL.
  Default is `http://localhost:8053/xml/v3`.
- **gather_memory_contexts** bool: Report per-context memory statistics.
- **gather_views** bool: Report per-view query statistics.
- **timeout** Timeout for http requests made by bind (example: "4s").

The following table summarizes the URL formats which should be used,
depending on your BIND version and configured statistics channel.

| BIND Version | Statistics Format | Example URL                   |
| ------------ | ----------------- | ----------------------------- |
| 9.6 - 9.8    | XML v2            | `http://localhost:8053`         |
| 9.9          | XML v2            | `http://localhost:8053/xml/v2`  |
| 9.9+         | XML v3            | `http://localhost:8053/xml/v3`  |
| 9.10+        | JSON v1           | `http://localhost:8053/json/v1` |

### Configuration of BIND Daemon

Add the following to your named.conf if running Telegraf on the same host
as the BIND daemon:

```json
statistics-channels {
    inet 127.0.0.1 port 8053;
};
```

Alternatively, specify a wildcard address (e.g., 0.0.0.0) or specific
IP address of an interface to configure the BIND daemon to listen on that
address. Note that you should secure the statistics channel with an ACL if
it is publicly reachable. Consult the BIND Administrator Reference Manual
for more information.
