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. 

yum install perl-Paws

Setup​

  1. Install the Centreon package on every Centreon poller expected to monitor AWS services generating charges:
yum install centreon-plugin-Cloud-Aws-Billing-Api
  1. On the Centreon Web interface, install the AWS Billing Centreon Monitoring Connector on the Configuration > Monitoring Connector Manager page.

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 CLI using the centreon-engine user account (su - centreon-engine) and test the Plugin by running the following command with the name of your backup vault:

/usr/lib/centreon/plugins//centreon_aws_billing_api.pl \
    --plugin=cloud::aws::billing::plugin \
    --mode=estimated-charges \
    --custommode='awscli' \
    --region=us-east-1 \
    --aws-secret-key='xxx' \
    --aws-access-key='xxx' \
    --service='AWSBackup' \
    --warning-billing='' \
    --critical-billing='' \

The expected command output is shown below:

OK: Service 'AWSBackup' Estimated Charges: 0.85 USD | 'AWSBackup#billing.estimatedcharges.usd'=0.85USD;;;;

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

/usr/lib/centreon/plugins//centreon_aws_billing_api.pl \
    --plugin=cloud::aws::billing::plugin \
    --mode=estimated-charges \
    --help

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

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