BIND 9 Nameserver Input Plugin

This plugin collects metrics from BIND 9 nameservers 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.

Global configuration options

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 for more details.

Configuration

toml

# 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.
