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
aws-cli-installation

yum install perl-Paws

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

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

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_sns_api.pl \
    --plugin=cloud::aws::sns::plugin \
    --mode=notifications \
    --custommode=awscli \
    --aws-secret-key='*******************' \
    --aws-access-key='**********' \
    --region='eu-west-1' \
    --proxyurl='http://myproxy.mycompany.org:8080'
    --statistic=sum \
    --timeframe='600' \
    --period='60' \
    --topic-name='my_sns_topic_1' \
    --filter-metric='NumberOfNotificationsFailed' \
    --warning-notifications-failed=0 \
    --critical-notifications-failed=5 \
    --verbose

Expected command output is shown below:

OK: 'my_sns_topic_1' Statistic 'Sum' number of notifications failed: 0 | 'my_sns_topic_1~sum#sns.notifications.failed.count'=0;;;;
Notifications for topic 'my_sns_topic_1' :
    Statistic 'Sum' number of notifications failed: 0 

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

/usr/lib/centreon/plugins//centreon_aws_sns_api.pl \
    --plugin=cloud::aws::sns::plugin \
    --mode=notifications \
    --help

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

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