Plugin dependencies

To interact with Amazon APIs, you can use either use the awscli binary provided by Amazon or paws, a Perl AWS SDK (recommended). You must install it on every poller expected to monitor AWS resources.

For now, it is not possible to use paws if you are using a proxy to reach AWS Cloudwatch APIs.

perl-Paws-installation

yum install perl-Paws

aws-cli-installation

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install

3. On the Centreon web interface, on page Configuration > Monitoring Connector Manager, install the Amazon SQS Centreon Monitoring Connector.

Configuration

• Log into Centreon and add a new host through Configuration > Hosts.
• In the IP Address/DNS field, set the following IP address: 127.0.0.1.
• Aplly the Cloud-Aws-Sqs-custom template to the host.
• Once the template is applied, fill in the corresponding macros. Some macros are mandatory.

	QUEUENAME	Queue name (Default : '.*')
	PROXYURL	Configure proxy URL
	EXTRAOPTIONS	Any extra option you may want to add to every command line (eg. a --verbose flag)
	DUMMYSTATUS	Host state. Default is OK, do not modify it unless you know what you are doing
	DUMMYOUTPUT	Host check output. Default is 'This is a dummy check'. Customize it with your own if needed

How to check in the CLI that the configuration is OK and what are the main options for?

Once the plugin is installed, log into your Centreon poller's CLI using the centreon-engine user account (su - centreon-engine) and test the plugin by running the following command (Some of the parameters such as --proxyurl have to be adjusted):

/usr/lib/centreon/plugins/centreon_aws_sqs_api.pl \
    --plugin=cloud::aws::sqs::plugin \
    --mode=queues \
    --custommode=awscli \
    --aws-secret-key='*******************' \
    --aws-access-key='**********' \
    --region='eu-west-1' \
    --proxyurl='http://myproxy.mycompany.org:8080'
    --statistic=average \
    --timeframe='600' \
    --period='60' \
    --queue-name='my_sqs_queue_1' \
    --filter-metric='NumberOfMessagesSent|NumberOfMessagesReceived' \
    --critical-messages-sent=1: \
    --critical-messages-received=1: \
    --verbose

Expected command output is shown below:

OK: 'my_sqs_queue_1' Statistic 'Average' number of messages sent: 45, number of 
messages received: 32 | 'my_sqs_queue_1~average#sqs.queue.messages.sent.count'=45;;1:;; 'my_sqs_queue_1~average#sqs.queue.messages.received.count'=32;;1:;;
SQS Queue'my_sqs_queue_1'
    Statistic 'Average' number of messages sent: 45, number of messages received: 32  

All available options for a given mode can be displayed by adding the --help parameter to the command:

/usr/lib/centreon/plugins//centreon_aws_sqs_api.pl \
    --plugin=cloud::aws::sqs::plugin \
    --mode=queues \
    --help

All available modes can be displayed by adding the --list-mode parameter to the command:

/usr/lib/centreon/plugins//centreon_aws_sqs_api.pl \
    --plugin=cloud::aws::sqs::plugin \
    --list-mode
