+title: "ISC Bind monitoring with Netdata"

+sidebar_label: "ISC Bind"
+-->
+
+# ISC Bind monitoring with Netdata
+
+Collects Name server summary performance statistics using `rndc` tool.
+
+## Requirements
+
+- Version of bind must be 9.6 +
+- Netdata must have permissions to run `rndc stats`
+
+It produces:
+
+1. **Name server statistics**
+
+ - requests
+ - responses
+ - success
+ - auth_answer
+ - nonauth_answer
+ - nxrrset
+ - failure
+ - nxdomain
+ - recursion
+ - duplicate
+ - rejections
+
+2. **Incoming queries**
+
+ - RESERVED0
+ - A
+ - NS
+ - CNAME
+ - SOA
+ - PTR
+ - MX
+ - TXT
+ - X25
+ - AAAA
+ - SRV
+ - NAPTR
+ - A6
+ - DS
+ - RSIG
+ - DNSKEY
+ - SPF
+ - ANY
+ - DLV
+
+3. **Outgoing queries**
+
+- Same as Incoming queries
+
+## Configuration
+
+Edit the `python.d/bind_rndc.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/bind_rndc.conf
+```
+
+Sample:
+
+```yaml
+local:
+ named_stats_path : '/var/log/bind/named.stats'
+```
+
+If no configuration is given, module will attempt to read named.stats file at `/var/log/bind/named.stats`

+# netdata python.d.plugin configuration for bind_rndc
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+# - global variables
+# - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# penalty indicates whether to apply penalty to update_every in case of failures.
+# Penalty will increase every 5 failed updates in a row. Maximum penalty is 10 minutes.
+# penalty: yes
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+# name: myname # the JOB's name as it will appear at the
+# # dashboard (by default is the job_name)
+# # JOBs sharing a name are mutually exclusive
+# update_every: 1 # the JOB's data collection frequency
+# priority: 60000 # the JOB's order on the dashboard
+# penalty: yes # the JOB's penalty
+# autodetection_retry: 0 # the JOB's re-check interval in seconds
+#
+# Additionally to the above, bind_rndc also supports the following:
+#
+# named_stats_path: 'path to named.stats' # Default: '/var/log/bind/named.stats'
+#------------------------------------------------------------------------------------------------------------------
+# IMPORTANT Information
+#
+# BIND APPEND logs at EVERY RUN. Its NOT RECOMMENDED to set update_every below 30 sec.
+# STRONGLY RECOMMENDED to create a bind-rndc conf file for logrotate
+#
+# To set up your BIND to dump stats do the following:
+#
+# 1. add to 'named.conf.options' options {}:
+# statistics-file "/var/log/bind/named.stats";
+#
+# 2. Create bind/ directory in /var/log
+# cd /var/log/ && mkdir bind
+#
+# 3. Change owner of directory to 'bind' user
+# chown bind bind/
+#
+# 4. RELOAD (NOT restart) BIND
+# systemctl reload bind9.service
+#
+# 5. Run as a root 'rndc stats' to dump (BIND will create named.stats in new directory)
+#
+#
+# To ALLOW NETDATA TO RUN 'rndc stats' change '/etc/bind/rndc.key' group to netdata
+# chown :netdata rndc.key
+#
+# The last BUT NOT least is to create bind-rndc.conf in logrotate.d/
+# The working one
+# /var/log/bind/named.stats {
+#
+# daily
+# rotate 4
+# compress
+# delaycompress
+# create 0644 bind bind
+# missingok
+# postrotate
+# rndc reload > /dev/null
+# endscript
+# }
+#
+# To test your logrotate conf file run as root:
+#
+# logrotate /etc/logrotate.d/bind-rndc -d (debug dry-run mode)
+#
+# ----------------------------------------------------------------------
