#!/bin/sh
#
# plugin for munin to monitor usage of unbound servers.
# To install copy this to /usr/local/share/munin/plugins/unbound_munin_
# and use munin-node-configure (--suggest, --shell).
#
# (C) 2008 W.C.A. Wijngaards.  BSD Licensed.
#
# To install; enable statistics and unbound-control in unbound.conf
#	server:		extended-statistics: yes
#			statistics-cumulative: no
#			statistics-interval: 0
#	remote-control:	control-enable: yes
# Run the command unbound-control-setup to generate the key files.
#
# Environment variables for this script
#	statefile	- where to put temporary statefile.
#	unbound_conf	- where the unbound.conf file is located.
#	unbound_control	- where to find unbound-control executable.
#	spoof_warn	- what level to warn about spoofing
#	spoof_crit	- what level to crit about spoofing
#
# You can set them in your munin/plugin-conf.d/plugins.conf file
# with:
# [unbound*]
# user root
# env.statefile /usr/local/var/munin/plugin-state/unbound-state
# env.unbound_conf /usr/local/etc/unbound/unbound.conf
# env.unbound_control /usr/local/sbin/unbound-control
# env.spoof_warn 1000
# env.spoof_crit 100000
#
# This plugin can create different graphs depending on what name
# you link it as (with ln -s) into the plugins directory
# You can link it multiple times.
# If you are only a casual user, the _hits and _by_type are most interesting,
# possibly followed by _by_rcode.
#
#	unbound_munin_hits	- base volume, cache hits, unwanted traffic
#	unbound_munin_queue	- to monitor the internal requestlist
#	unbound_munin_memory	- memory usage

=head1 NAME

unbound_munin_ - Munin plugin to monitor the Unbound DNS resolver.

=head1 APPLICABLE SYSTEMS

System with unbound daemon.

=head1 CONFIGURATION

[unbound*]
  user root
  env.statefile /usr/local/var/munin/plugin-state/unbound-state
  env.unbound_conf /usr/local/etc/unbound/unbound.conf
  env.unbound_control /usr/local/sbin/unbound-control
  env.spoof_warn 1000
  env.spoof_crit 100000

Use the .env settings to override the defaults.

=head1 USAGE

Can be used to present different graphs. Use ln -s for that name in
the plugins directory to enable the graph.
unbound_munin_hits	- base volume, cache hits, unwanted traffic
unbound_munin_queue	- to monitor the internal requestlist
unbound_munin_memory	- memory usage
unbound_munin_by_type	- incoming queries by type
unbound_munin_by_class	- incoming queries by class
unbound_munin_by_opcode	- incoming queries by opcode
unbound_munin_by_rcode	- answers by rcode, validation status
unbound_munin_by_flags	- incoming queries by flags
unbound_munin_histogram - histogram of query resolving times
