Description

Installs AWS Cloudwatch Monitoring Scripts and sets up a cron entry to push system metrics to Cloudwatch.

More info on the monitoring scripts can be found here.

Setup

What cloudwatch affects

Creates a crontab entry in order to routinely push metrics to Cloudwatch. This cron job defaults to being run as the user running Puppet or root.

The Cloudwatch monitoring scripts that this module installs are dependent on the following packages and they will be installed automatically, unless $manage_dependencies is set to false.

  • RHEL/CentOS/Fedora:

    • perl-Switch
    • perl-DateTime
    • perl-Sys-Syslog
    • perl-LWP-Protocol-https
    • perl-Digest-SHA
    • unzip
  • Amazon Linux:

    • perl-Switch
    • perl-DateTime
    • perl-Sys-Syslog
    • perl-LWP-Protocol-https
    • unzip
  • Debian/Ubuntu:

    • libwww-perl
    • libdatetime-perl
    • unzip

Setup Requirements

Once this module has been installed and your manifest has been applied to your Puppet nodes, Cloudwatch metrics will be pushed every minute by default.

You must setup AWS IAM credentials on your instances or assign an IAM role to your instances which has access to push data to Cloudwatch. More info on this can be found here.

Beginning with cloudwatch

Usage

  • Install the module: puppet module install MasterRoot24-cloudwatch
  • Include the module in your manifests: node 'my-node.example.com' { include cloudwatch }
