=head1 NAME
check_rabbitmq_objects - Nagios plugin using RabbitMQ management API to
count the number of various broker objects
=head1 SYNOPSIS
check_rabbitmq_objects [options] -H hostname
=head1 DESCRIPTION
Use the management interface of RabbitMQ to count the number of various
broker objects. These are published as performance metrics for the check.
Currently the following objects are counted:
=over
=item * vhost
=item * exchange
=item * binding
=item * queue
=item * channel
=back
It uses Nagios::Plugin and accepts all standard Nagios options.
=head1 OPTIONS
=over
=item -h | --help
Display help text
=item -v | --verbose
Verbose output
=item -t | --timeout
Set a timeout for the check in seconds
=item -H | --hostname | --host
The host to connect to
=item --port
The port to connect to (default: 55672)
=item --ssl
Use SSL when connecting (default: false)
=item --username | --user
The user to connect as (default: guest)
=item --pass
The password for the user (default: guest)
=back
=head1 EXAMPLES
The defaults all work with a standard fresh install of RabbitMQ, and all that
is needed is to specify the host to connect to:
check_rabbitmq_objects -H rabbit.example.com
This returns a standard Nagios result:
RABBITMQ_OBJECTS OK - Gathered Object Counts | vhost=1;; exchange=7;;
binding=2;; queue=1;; channel=0;;
=head1 ERRORS
The check tries to provide useful error messages on the status line for
standard error conditions.
Otherwise it returns the HTTP Error message returned by the management
interface.
=head1 EXIT STATUS
Returns zero if check is OK otherwise returns standard Nagios exit codes to
signify WARNING, UNKNOWN or CRITICAL state.
