NAME¶

check_rabbitmq_connections - Nagios plugin using RabbitMQ management API to count the connections running, their state and optionally limit these checks to specific connected client user accounts.

SYNOPSIS¶

check_rabbitmq_connections [options] -H hostname

DESCRIPTION¶

Use the management interface of RabbitMQ to count the number of established connections, those that are not in state running and also their throughput. All values are published as performance metrics for the check.

Critical and warning thresholds can be set for each of the metric.

It uses Monitoring::Plugin and accepts all standard Nagios options.

OPTIONS¶

-h | --help

Display help text

-v | --verbose

Verbose output

-t | --timeout

Set a timeout for the check in seconds

-H | --hostname | --host

The host to connect to

--port

The port to connect to (default: 55672)

--ssl

Use SSL when connecting (default: false)

--username | --user

The user to connect as (default: guest)

--pass

The password for the user (default: guest)

-w | --warning

The warning levels for each count of connections established, connections in a non-running state (flow, blocked), receive rate and send rate. This field consists of one to four comma-separated thresholds. Specify -1 if no threshold for a particular count.

-c | --critical

The critical levels for each count of connections established, connections in a non-running state (flow, blocked), receive rate and send rate. This field consists of one to four comma-separated thresholds. Specify -1 if no threshold for a particular count.

--clientuser

Specify the client username to limit the connections checks for.

THRESHOLD FORMAT¶

The format of thresholds specified in --warning and --critical arguments is defined at <http://nagiosplug.sourceforge.net/developer-guidelines.html#THRESHOLDFORMAT>.

For example to be crtical if more than 5 connections, more than 2 connections not running, less than 200b/s received use

--critical=5,2,200,-1

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_connections -H localhost -w 1: -c 1:

This returns a standard Nagios result:

  RABBITMQ_CONNECTIONS CRITICAL - connections CRITICAL (0),
    connections_notrunning WARNING (0), receive_rate OK (0) send_rate OK (0) |
    connections=0;;1: connections_notrunning=0;1:; receive_rate=0;; send_rate=0;;

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.

EXIT STATUS¶

Returns zero if check is OK otherwise returns standard Nagios exit codes to signify WARNING, UNKNOWN or CRITICAL state.
